Tips to Help with Plaque Prevention and Removal

Published Date

Inadequate brushing and flossing leaves particles of food and drink on the gums and teeth, which attract bacteria that turn into the sticky film called plaque. If that is not cleaned off within a few days it can harden into tartar, which has to be removed by a dental hygienist. Otherwise, this periodontal infection will eventually cause the gums to pull back their support for teeth, which will fall out or need to be removed. Plaque can also cause cavities that become so large that teeth have to be extracted.

The two top tips to prevent these things from happening:

First, if you have not had a recent physical dental exam by Dr. Louie, you should know that the American Dental Association recommends that this be done twice a year to catch oral problems in their early stages. If he suspects there may be cavities that are hidden or a periodontal infection that may have reached into the jawbone, you will need a digital x-ray (involving minimal radiation).

Professional Cleaning

Second, you should also receive a professional cleaning by your hygienist at least semi-annually, more often if she probes and discovers deep gum infections. She has the tools and techniques to do a much better job of cleaning hard-to-reach areas of your mouth than you can. She will also inject an antibacterial solution if needed to stop a serious infection. She can also note when even this is not enough and cleaning needs to be done below the gum line by Dr. Louie.

Brushing and Flossing

Of course, brushing and flossing correctly can prevent plaque formation, but few of us grew up understanding exactly how to do this. Brushing needs to be done twice a day for two minutes each time, ideally after breakfast (which will allow you to remove both the food particles from the meal, as well as the bacteria that collects in the mouth overnight) and then after your last snack at night, when you floss. If you are not sure exactly how to do this, ask your hygienist to show you.

There are other tools your dentist or hygienist can recommend for your plaque prevention and removal, such as an electric toothbrush, a water flosser, small bristle brushes that can clean tight spaces, a periodontal-grade toothpaste, and a dentist-approved mouthwash.

Diet Habits

Drinking more water and chewing gum with xylitol (a bacteria-fighting sweetener) will prevent your mouth from getting dry and not forming sufficient saliva, which also keeps periodontal bacteria in check. Ultimately, if you eat a healthy diet of proteins, good fats, and complex (not refined) carbohydrates, such as whole grains, seeds, nuts, peas, and vegetables, you are far less likely to create the conditions in your mouth for plaque to develop. 

But if your gums have already started to bleed, you have an advanced periodontal infection and need to call today to set up an appointment for an exam.

How to Save a Damaged Tooth

Published Date

There are many ways that teeth can be damaged, including due to car or bike accidents, falling, sports, grinding teeth unconsciously, gnawing on pens, pulling clothes off with teeth, munching on ice, eating hard candy, chewing tough jerky, and the pits of fruits and vegetables. Or the harm to a beautiful smile could just be severe discoloration.

It is important to have Dr. Louie examine any damage ASAP to determine what needs to be done to repair or save the tooth.

A Chipped or Sensitive Tooth

If a tooth has been chipped and is painful or sensitive, Dr. Louie could create a customized veneer, a thin piece of dental porcelain, which is attached to the front to cover a minor crack and strengthen the tooth. Unlike most dental practices, we have a an iTero scanner that can produce this while you wait. He can also create an extremely thin veneer called a Lumineer, which requires less enamel to be shaved off the front compared with conventional veneers, which is done to keep a veneer from sticking out artificially.

Damaged Teeth from Grinding

If the damage has been due to grinding your teeth while you sleep, Dr. Louie can either manufacture a customized dental crown to cover the damage to each and protect them from further harm. He will also provide a personalized nightguard, a mouthguard worn while sleeping, which will stop the grinding (known as bruxism).

For some minor cases, such as small chipping, malformed teeth, gaps between them, or staining, these can be covered by a composite resin known as dental bonding. A shade is chosen and the bonding is applied, sculpted, and then hardened with a special curing light.

Infected Tooth Root

If severe pain is being caused by an infected tooth root, a root canal procedure can clean out the infected pulp, fill the canals with neutral material to prevent this from happening again, and restore the tooth. Contrary to the popular expression about painful experiences, “I’d rather have a root canal,” the procedure itself does not cause pain, it stops it. 

If you have a damaged tooth, call Dr. Louie to set an appointment for a full dental exam to determine what your best options are for restoring your full oral health.

How Chronic Stress Affects Your Oral Health

Published Date

Life is full of stress of all kinds for everyone, from job and financial problems to accidents and family health crises. The three years of the pandemic have increased the stress by magnitudes, whether not because of not being able to socialize with friends or to buy things we thought would always be available.

Unless you have perfected your oral health care regimen, challenges like cavities, periodontal disease, and teeth that fall out may have added to normal stress. But what may not be fully appreciated is that chronic stress of all kinds, including mental health, can impact your dental health.

According to the National Health and Nutrition Examination Survey, two-third of people with clinical depression reported toothaches and half of those rated their oral health as fair to poor. The reasons for this range from unhealthy diets, lack of discipline to brush twice daily and floss once, and a tendency not to have a dental exam the recommended two times a year. Small cavities can become so serious even in six months that the entire tooth needs to be extracted.

Stress has Many Effects on the Body

Stress of all kinds has an effect  on the body, including dental health. It drives up the level of the hormone cortisol, which weakens the immune system, so periodontal bacteria can find a welcoming home. Some antidepressants and anti-anxiety medications can dry up saliva, which normally fights oral bacteria. Smoking also dries the mouth and often the habit gets worse under stress.

Stress often leads to unconsciously grinding teeth while you sleep, known as bruxism, which can damage the crowns of teeth. These need to be repaired and a personalized nightguard created by Dr. Louie to prevent this from happening again.

Increased Tension Affects TMJ

Stress can cause tension in your jaw and dislocation of the TMJ, the set of hinges on both sides of the mouth that connect the lower jaw to the skull. You can feel these by placing your fingers just in front of your lower earlobes and opening and closing your mouth. The symptoms can be difficulties in even doing that or a popping sound when you do. Many suffering from TMJ Disorder also have soreness around the face, neck, or shoulders.

Cold Sores

Canker sores are mouth ulcers that can be due to a deficiency of vitamin B complex and any kind of stress. Cold sores are caused by the herpes simplex virus. This can be dormant until triggered by stress and these sores appear as lesions on the lips. Other oral infections can appear as red or white spots or white lines are usually due to stress, smoking, and too many acidic beverages (such as sodas) and foods (especially citrus).

If you have not had a full dental examination in the past year, contact our Los Angeles dentist and team today.

What to Ask at Your Dental Implants Consultation

Published Date

As you probably know, the older one gets, the more likely we will have missing teeth, whether due to accidents or because poor brushing and flossing habits result in some falling out or needing to be extracted. You no doubt have questions about whether a dental implant is your best option.

Are there less expensive and quicker alternatives to implants?

Dentures are not an ideal solution because they do not stop the natural erosion of the jawbone that occurs when teeth are missing, which is why they need to be adjusted for fit about every five years. Dental bridges can slow this down by suspending a crown that looks like a tooth between the two teeth on either side of the gap, tricking the body into thinking no tooth is missing, but bridges typically only last 5-7 years. Dental implants can be a permanent solution with good oral care and so very cost-effective. The success rate for experts like Dr. Louie is about 95%.

How long does it take for each tooth to be replaced by an implant?

If a tooth is loose, it first needs to be extracted and the socket allowed to heal, which could take a couple of months. Otherwise, the first step will be for Dr. Louie to use his iTero intraoral scanner to take a 3D image of the area of the missing tooth and transmit the image to a top dental lab to create the biocompatible titanium implant. Because of this fast and highly-accurate digital process, you will quickly be able to have it ready to be screwed into the jawbone. Then you will need to wait a few months for the implant to integrate with the jawbone. The lab will have also made the dental crown, which will look exactly like your lost tooth (or teeth) and this will be attached to the top of the implant as soon as the implant has bonded. But multiple implants can be done in the same time frame.

When can I start eating normally after an implant?

In the first couple of weeks, it is important to rely on healthy soft foods like yogurt, eggs, smoothies, protein shakes, and soups. Drink lots of water, which will wash away food particles, buffer teeth from bacterial acids, and keep tissues hydrated. Avoid spicy, sour, and sweet foods, since they can irritate the surgical site while it is healing. Do not eat hard, crunchy, and sticky foods for a couple months, since they could dislodge the implant. But once the implant has become settled, it is a true treatment for missing teeth, then you can eat normally (and hopefully healthfully). 

Call today for a full exam and consultation to determine if dental implants are right for your case.

Can a Chipped Tooth Heal on Its Own?

Published Date

The anxiety after realizing you’ve chipped a tooth can be overwhelming. Sometimes, the chip is just a filling that comes from wear and tear. But other times, it may be a large piece of your tooth broken off due to an injury, which can be a much more severe issue. 

Chips that are small and not causing any pain or sensitivity can sometimes be left alone and eventually smooth out on their own as you continue to use your teeth for biting and chewing. But if the chip is large, jagged, or causing you pain, it’s best to see a dentist right away.

Do Teeth Grow Back?

Teeth are like any other part of your body—if they’re injured, they need treatment. However, teeth don’t just heal on their own like other tissues in your body. When a bone is broken, for example, it will grow back together over time. But when a tooth is broken, it can’t grow back. 

A chipped tooth can sometimes be repaired with a filling, bonding, or veneers. If the chip is large, you may need a crown. If the tooth is severely damaged, it may need to be extracted. Let’s not forget that a chipped tooth can also be a sign of a more serious underlying dental issue, such as tooth decay or gum disease. So it’s essential to see a dentist in order to get an accurate diagnosis and treatment plan.

How Do Dentists Treat a Chipped Tooth?

The type of treatment you need will depend on the size and location of the chip, as well as the severity of the damage.

Small Chips

If the chip is small and not causing any pain or sensitivity, your dentist may just smooth it out with a file. This is called “fracture smoothing.” Fracture smoothing is often used for chips on the chewing surfaces of teeth that are not visible when you smile.

If the chip is on a front tooth and is visible when you smile, your dentist may use bonding to repair it. Bonding is a process where a tooth-colored resin is applied to the tooth and hardened with a light. Bonding can also be used to change the shape, color, or length of your teeth.

Large Chips

If the chip is large, your dentist may use bonding or veneers to repair it. Veneers are thin, porcelain shells that are bonded to the front of your teeth. They can be used to change the shape, color, size, or length of your teeth.

If the chip is large and the tooth is severely damaged, you may need a crown. A crown is a “cap” that covers the entire tooth. It can be made from metal, porcelain, or a combination of both.

You may need a root canal if the chip is large and the tooth is severely damaged. A root canal is a procedure where the nerve and blood supply are removed from the tooth. The tooth is then filled with a rubber-like material and sealed.

If the chip is large and the tooth is severely damaged, you may need to have the tooth extracted and replaced with an artificial tooth.

A chipped tooth can “heal” on its own if it is a small chip and does not cause any pain or sensitivity. However, the tooth does not regrow or repair itself. It simply may smooth out over time as you continue to use your teeth for biting and chewing. If the chip is large, jagged, or causing pain, it is best to see a dentist right away for an accurate diagnosis and treatment plan.

For cosmetic purposes, a chipped tooth can sometimes be repaired with a filling, bonding, or veneers. If the chip is large, you may need a crown. If the tooth is severely damaged, it may need to be extracted. Regardless of the issue, you can schedule a consultation with our Los Angeles dentist to determine which treatment option can work for you.

Dental Injuries After a Car Accident

Published Date

If you are in a car accident, it is likely to involve injuries to your mouth that would require our expertise to heal and restore to health.

Sudden crashes often result in the head of the driver and anyone in the front passenger seat hitting the steering wheel or the dashboard. Airbags don’t always stop these injuries for a variety of reasons. The most common result is chipped teeth, for which dental bonding or veneers would provide the remedy. Our veneers are made of a strong cosmetic porcelain that can last for 10-15 years with proper care.


Cracked Teeth

The second most common injury from an auto accident is cracked teeth and a dental crown can hold them together and protect from further damage any tooth that has been cracked or fractured.

If teeth are knocked out in the accident or so severely damaged that they need to be extracted, dental implants are the ideal replacement. An implant consists of a biocompatible metal screw that is inserted into the jawbone and attached to a crown that looks exactly like a natural tooth. This can be a permanent solution.

If teeth are missing for any reason, they always need to be replaced because otherwise the mouth goes through a process of causing neighboring teeth to lean towards the gap, causing them and other teeth to become loose and they may eventually fall out. Alternatively, a dental bridge, which attaches an artificial tooth to neighboring teeth, could slow down this process. 


iTero Restorations

Crowns and implants can be made using our in-office iTero, which produces a highly-accurate 3-D digital image of the inside of your mouth, allowing Dr. Louie to plan the process, speed instructions to a dental lab, and make sure the results are an exact match to your natural teeth.

Another common injury from accidents is TMJ Disorder (short for the displacement of the  temporomandibular joint, the hinges that connect the lower jaw to the upper). You can feel them by holding your fingers just in front of your earlobes when you open and close your mouth and if they are displaced, they will make a popping or clicking sound when you do this. Or you may have trouble opening your mouth at all, feel pain in the hinges, soreness on the sides of your face, experience headaches, and neck or shoulder discomfort.

A customized orthotic splint is an oral appliance you can wear to get the jaw back in its proper place. Your bite can also be improved using crowns, bridges, implants, or Invisalign trays to prevent TMJD. We can also show you neuromuscular exercises to help and prescribe anti-inflammatories or muscle relaxers.

If you are in a car accident, call us as soon as possible for a full dental exam to discuss how Dr. Louie can help you recover.

Advantages of Getting Invisalign

Published Date

Los angeles ca dentist

The advantages of using the Invisalign system are greater than simply achieving a beautiful smile. With Invisalign’s clear, comfortable, and removable devices, you can expect to see significant and lasting results as well as a variety of oral health benefits.

What is Invisalign?

Invisalign is a highly effective teeth alignment program that provides a welcomed alternative to traditional wire braces—in less time. Invisalign corrects any tooth abnormality, including over-bites, under-bites, cross-bites, overcrowded, gapped and protruding teeth. But that’s not all. Here are some of the added benefits of using Invisalign:

Overall health

In addition to fixing crooked, crowded and gapped teeth, Invisalign also corrects abnormal bite functions: for example, when the upper and lower jaws fail to align properly when your mouth is closed. If bite issues are left unmanaged, they can lead to further oral health problems, like cavities, tooth loss, gum infections, erosion of tooth enamel and difficulty speaking and/or eating.

Gum disease is a major factor in mouths where teeth are too widely spaced or crowded. Once your teeth are properly aligned, gums fit around them more snugly, providing a stronger defense against infections. The straighter your teeth, the healthier your mouth.


Invisalign aligners gradually and gently move teeth into their proper positions, without the unsightly metal brackets that come with traditional braces. Invisalign appliances are made from medical-grade polyurethane resin; their smooth, soft edges provide greater control throughout the teeth-straightening process, shifting your teeth slightly, vertically and horizontally. They are virtually indestructible, invisible and best of all, comfortable—and, also unlike metal braces, Invisalign aligners are removable, allowing you to brush and floss your teeth as normal while maintaining a greater level of oral hygiene.


Another benefit to choosing Invisalign is that you get to spend more time doing what you love, and less time in a dentist’s chair. Unlike conventional fixed braces, typical Invisalign treatment plans last about 12 months, with the aligners worn roughly 22 hours per day. That means fewer in-person check-ups!

Invisalign also grants you the freedom to continue enjoying the foods you love. Simply remove your aligner and tuck into corn on the cob, whole apples, and other previously tricky solids that wreaked havoc on wire braces and allowed for trapped debris, thus leading to tooth decay and gum disease.

Boost in confidence

Invisalign can drastically boost your self-confidence by allowing you to show off your beautiful smile—with the added knowledge that your oral health is in top condition.

Teens and young adults

Protruding, crooked or even missing teeth can have a detrimental effect on the self-esteem of teenagers and young adults, resulting in feelings of unattractiveness. Teens who experience low levels of self-confidence during their formative years are vulnerable to negative influences and are more likely to become depressed. Fortunately, teens are now opting for the Invisalign treatment over conventional braces due to the former’s discreet and unnoticeable fit.

If you still have questions about Invisalign, our experts at Shervin M. Louie, DDS are always available to help. Call today!

3 Things You Should Know About Tooth Contouring

Published Date

Tooth Contouring

Tooth contouring, a procedure also called enameloplasty) is a way to alter the shape of a patient’s tooth, not to mention the surface, which can start to become stained and experience plaque and tartar buildup over time.

Pits and bumps can also start to develop in the tooth which can lead to bacterial growth and cavities.

The benefits of a tooth contouring and reshaping procedure at Shervin M. Louie, DDS extend beyond simple aesthetics and reach into functional and preventive as well.

Below are a few things you should know about the tooth contouring procedure.

1.) Tooth Contouring is Painless!

Many dental procedures involve the use of novocaine or some other type of numbing agent. But not the tooth contouring procedure. Tooth contouring is simple, fast, and relatively pain-free.

2.) You Have to Have a Sufficient Amount of Enamel

The best candidates for the tooth contouring procedure already have a fair amount of tooth enamel to work with. For those of our patients who are in need of more major dental restoration work or lack the necessary amount of enamel for the procedure will want to consider other options like dental veneers.

3.) Tooth Contouring is an Easy Way to Boost Self-Confidence

A great smile will open new doors you didn’t know existed before. Having a smooth, contoured set of pearly whites will help you stand out in a crowd and leave you with a smile more often — on a daily basis!

If you have any questions about the tooth contouring procedure, please contact Shervin M. Louie, DDS to schedule your consultation today. We have a long track record of giving our patients the celebrity treatment, whether they’re a celebrity or not! Don’t wait another day to achieve the smile of your dreams.

Going Overboard on Bleaching?

Published Date

Woman with nice white teeth

Teeth Whitening and Bleachorexia

Teeth whitening products have given people the opportunity to smile brightly after years of staining their teeth with coffee, tobacco, tea, and other products that aren’t good for dental health and tooth color.

However, they’ve also given rise to a new issue that dentists have begun calling bleachorexia. Bleachorexia describes the act of over-bleaching one’s teeth to make them as white as possible. Not only do overtly white teeth look unnatural, but the act of over bleaching them can actually destroy them.

Therefore, it’s important to know the effects of bleachorexia and how to prevent them.

What Does Bleachorexia Cause?

Bleachorexia can cause several effects that range from simply uncomfortable to downright painful. The intensity of these effects depends on how often a bleaching product is abused, the starting condition of the user’s teeth, and the particular product being used.

A bleaching agent works by using peroxide to lessen the effects of stains that have built up by drinking coffee, tea, smoking, using chewing tobacco, and other habits that aren’t good for the coloring and health of teeth.

This peroxide is fairly strong and it causes teeth to become very sensitive to varying temperatures. However, it’s usually not a permanent problem if the user stops using the bleaching product. The sensitivity will typically cease soon after the bleaching agent is removed from the user’s teeth cleaning regimen.

Another common effect of bleaching is irritation in the gums and throat. This is another symptom that’s caused by the peroxide used to whiten the teeth. The gums and throat simply aren’t good at resisting corrosive chemicals such as peroxide.

It’s not a very serious side-effect of bleachorexia, but it is an annoyance and it’s avoidable by using ADA-approved products, or by having a licensed dentist perform the whitening.

The most serious side-effect of over-bleaching is tooth erosion. If teeth are exposed to bleaching agents too often and for too long, the enamel that protects teeth is destroyed. This causes a number of long-lasting oral health issues and quite a bit of pain.

After an individual bleaches the enamel off of their teeth, professional help is a necessity. It’s best to simply have a professional do the bleaching properly to avoid the effects of improper bleaching.

Dr. Shervin M. Louie, DDS: An Expert in Preventing Bleachorexia

Dr. Louie is a cosmetic dentist in Los Angeles. He recommends using only ADA-approved products for teeth whitening. It’s also recommended to use them under the watchful eye of a licensed dental expert.

However, Dr. Louie also provides his patients with ADA-approved kits that they can use at home. That removes the guesswork involved in finding an effective product. If you’re looking for professional teeth whitening services, you’ll find some of the best at Smile in LA.
