Products & Services

Holistic Dentistry

Holistic dentistry–sometimes called biologic or natural dentistry–emphasizes that your body is an interconnected whole, that your teeth are part of a system and need to be treated that way, and that your entire body is healthiest–and you’re happiest–when all its systems are working properly and working together.

At Top Down Dental, we emphasize three main principles of holistic dentistry:

Materials used in dental treatment should be biocompatible or bio-inert
Choosing equipment, materials, and protocols that are safe for patients, the dental team, and the environment
Acknowledge the interconnectedness of the body to promote whole-body health–practice comprehensive dentistry

Following these principles allows us to provide our patients with the best possible dental care.

General Dentistry

The most common reason most of us visit a general dentistry office is for our regular check-ups and cleanings. But if those dental check-ups reveal signs of oral disease, we may need to get gum disease treatment. And if oral disease damages our teeth, or if our teeth experience injury as a result of trauma, we may need to get our teeth repaired.

TMD Treatment

Jaw pain, a sore neck, constant headaches, or an intense earache are sure signs that something isn’t right. If you’re living with any of these painful symptoms, you may have a TMJ disorder, often called TMD. Thankfully, there are TMD treatment options available to help.

TMD is a disorder of the temporomandibular joint – the jaw joint. The problem is most often caused by your bite. Your “bite” is a delicately engineered machine. The position of your jaw joints, and the way your jaw muscles work and your teeth fit together are critical for a healthy bite.

If any one of them is out of whack, eventually the machine will break down. TMD can cause damage to your teeth (wear, fractures, chips) , gum tissues (recession and bone loss) , jaw joints (arthritis, noises, locking) , and muscles (pain) .

Cosmetic Dentistry

Are you unhappy with the appearance of your teeth? Do you cover your mouth when you talk, laugh, or smile? Do all the pictures of you, even on the happiest days of your life, show you with a tight-lipped mouth because you don’t want to show your teeth? If any of those describe you, you may be looking for cosmetic dentistry to improve the appearance of your smile. Whether your teeth are crooked, discolored, short, gapped, chipped, or even missing, modern cosmetic dentistry can give you a bright, beautiful smile.

If you want to improve the appearance of your smile in Los Gatos, we can help. Please call (408) 477-1496 for an appointment with cosmetic dentist Nancy Nehawandian at Top Down Dental today.

Mercury Free Dentistry

One argument that is sometimes used to defend the use of mercury fillings it’s locked in the fillings. This is not true. There are several mechanisms by which it can exit the fillings.

First, it is a liquid metal, and it can evaporate, creating vapor in the mouth that is then inhaled. As a liquid, it is also able to seep through the tooth material. This not only discolors your tooth, it allows mercury to reach the bloodstream via the tooth pulp. Finally, chemical reactions in the mouth create an electric current similar to a battery. As part of the corrosion that occurs, it can be liberated from your fillings.

Experiments with sheep have shown that it only takes a few months for mercury to spread to the entire body, with the highest concentrations found in the kidney and liver. Pregnant sheep also showed that it passed into the fetus, concentrating in the liver and pituitary gland, which has a central role in development. Tests of both sheep and human breast milk showed that mercury could be found there as well, and that the concentration levels related to the presence of metal fillings.

OMD Treatment

Now that you recognize some of the symptoms that could indicate you have an OMD, you might wonder, how did I develop this condition?

OMDs occur when the normal developmental pattern of your face and jaw is interrupted or altered, usually by certain physical structures or habitual actions. Facial development is governed by the relationship between your muscles (including the lips, cheeks, and tongue) , teeth, and jaw. Dynamic, repeated pressure from the muscles stimulates the hard structures to grow, but also limits their growth. It’s the balance between these forces that governs development.

The normal balance can be altered by some bad habits, including:

Thumb or finger sucking
Mouth breathing
Biting nails
Chewing nonfood objects
Tongue thrusting
Inadequate chewing or avoiding hard foods
Poor swallowing habits
But it can also be changed by unusual physical structures such as a very restrictive tongue or lip tie.

Often, these habits and structures create a reinforcing pattern that can intensify with time. For example, a tongue tie might keep the tongue from stimulating development of the hard palate of the mouth. The hard palate is the roof of the mouth, but also the floor of the sinuses. If it doesn’t develop properly, the nasal airway may be narrow and inadequate. To supplement air from the nostrils, a person begins breathing through the mouth. In order to breathe through the mouth, the tongue must be on the bottom of the mouth, which means it provides even less stimulation to grow the upper palate, which results in improper chewing and swallowing.

Dental Implants

Dental implants are a welcome alternative to poor-fitting dentures or bridgework. Approximately 21% of all Americans are missing some or all of their teeth. Wearing a complete denture can cause gum loss, which often results in pain or discomfort. When loose dentures rub against your gums, the pain caused by the abrasion takes the joy out of pretty well everything that involves your teeth. Eating is not just a way to stay alive, in almost every human culture, eating is a social, happy event.

Fortunately, modern technology has advanced dental implants to the point where they can be used to replace as many missing or broken teeth as you have, even if you have lost all your teeth. These days, we’re living longer. With dental implants you can live your whole life with the greatest possible pleasure.

Once installed, your dental implants will give your new teeth solid support. Your bone heals around the root device, essentially becoming part of the structure of your jaw and face. When you use dental implants to replace missing or broken teeth, your face gets the structural support it needs to keep its natural shape and beauty.


Dentures with a Comprehensive Fit
The reason why many dentures fit or function poorly is that dentists don’t fit them properly. Economy dentures come in just a few sizes. A dentist selects the one closest to the size of your mouth, then takes an impression and makes sure they fit over your gums. Essentially, these fit only your gums. They may start out uncomfortably tight, but they quickly become loose and slippery. They may have limited function for chewing and may slip when you talk, laugh, or eat.

Traditional dentures are based on measurements of your mouth. They are custom-made to fit in your mouth as well as over your gums. These typically start out with a more comfortable fit. The quality fit may last longer. They are adequate for chewing and talking as long as you take care to modify eating techniques and carefully seat your dentures before speaking. They may not be comfortable for long wear, and you may experience jaw pain, headaches, and other TMJ symptoms.

But with the Denture Fountain of Youth ®, we use neuromuscular dentistry to get the most comprehensive fit yet. We not only measure your gums and mouth, we measure the muscles that are used in biting, chewing, and talking. We ensure that your dentures will support an optimal position of your jaw, which can make them more comfortable and will make talking, biting, and chewing more efficient. These don’t just fit your gums or your mouth, they fit your entire face.

Gum Disease Treatment

Gum disease, including gingivitis and periodontitis, are serious infections that, when left untreated, can have serious dental consequences like tooth loss and medical issues such as osteoporosis, heart disease, and stroke.

It begins when the bacteria in plaque (the sticky, colorless film that constantly forms on your teeth) builds up along and below your gum line. Once it sets in, periodontal disease inflames your gums with a toxic release of chemicals. These toxins damage your gums, causing them to pull away from your teeth resulting in gum and bone loss.

It only takes twenty four hours for plaque to turn into calculus (tartar) on your teeth! Once tartar is in place, it protects bacteria growing along and below your gum line. That’s why daily brushing and flossing is so important. It helps get rid of plaque and curtail tartar formation, but, no matter how diligently you brush, those hard to reach areas will always need special attention. Regular dental cleanings at Top Down Dental in San Jose/Los Gatos will help you keep tartar and gum disease at bay.


In our day and age, people are living longer. By preserving your teeth you can age gracefully and in good health. If you have a cross-bite, or if your teeth are misaligned, it’s easier for food and plaque to build up on your teeth. Food and plaque build-up can lead to gum disease, a real concern as we age as it leads to tooth loss and a myriad of health issues. An improper bite can hinder your ability to chew. People with “bad bites” often swallow big chunks of food, leading to intestinal pain and problems.

Sleep Apnea Treatment

During sleep apnea, your own body is literally choking you to death. The constant waking, even if you are not aware of it, causes daytime sleepiness at its mildest, or sleep deprivation at its worst. The lack of oxygen your body gets at night can lead to a host of serious health conditions.

Obstructive sleep apnea has been linked to:
Sleep apnea can cause various complications throughout your body, find out more at Top Down Dental in Los Gatos
Heart attack
Cardiovascular Disease
Right and left congestive heart failure
Gastro-esophageal Reflux Disease (GERD)
Cognitive Impairment
Sexual dysfunction
Type II Diabetes
Injury/death due to automobile accident from excessive daytime sleepiness

Dental Bridges

Dental bridges will do all three things for you. At Top Down Dental in San Jose/Los Gatos, Dr. Nancy Nehawandian is trained and experienced in both cosmetic and general dentistry.
With one eye on your beauty and one eye on your health, Dr. Nancy Nehawandian will recontour your abutment teeth to prepare them for crowns that will support the dental bridge. Next she’ll take an impression of your teeth and send it to a dental lab who will use it as a model to make your bridge. While your dental bridge is being fabricated, you’ll be fitted with a temporary bridge to protect your teeth and gums.
When your permanent dental bridge is completed, you’ll head back to Top Down Dental in San Jose/Los Gatos to be fitted. An excellent fit is critical for your smile, oral health and comfort, and Dr. Nehawandian may schedule subsequent visits to make sure you get the best fit possible.

Tooth-Colored Fillings

Tooth fillings are used when dental decay has created a cavity in your tooth. Left untreated, the cavity can shelter bacteria and trap food, causing the tooth to decay even more. Eventually, the cavity will pierce the inner chamber of the tooth, where the living portion of the tooth, called the pulp, is located. When bacteria infect the tooth, it may need to be extracted. Fillings are an early preventive treatment to preserve teeth. And these days they are attractive as well as functional.

The two different white filling options can help you get the optimal treatment for your teeth. Dental fillings can be made of a composite that is made of a plastic filled with hard ceramic particles that give it strength. These fillings are inexpensive and easily placed in a single visit. They polish nicely to emulate the luster of your natural teeth. But they may not last as long as we want. They can lose their polish, may become discolored, and can wear out.

Ceramic fillings are more of an investment of time and money, but they can be worth it. They are the most attractive fillings available, and they are the longest-lasting. The only drawback is that they require two visits to place, one where your tooth is prepared and one where the filling is placed.

Porcelain Veneers

Generally, dental veneers cost less than other cosmetic treatments, because the process is less invasive and less time consuming. Porcelain veneers can usually be installed in just two visits to Top Down Dental in San Jose/Los Gatos.

On your first visit, Dr. Nancy Nehawandian will prepare your teeth by buffing them lightly. Next she’ll shape the surface of your teeth so that the veneer will adhere well. After she takes a mold of your teeth, you’ll help choose the color.

You’ll be fitted with temporary veneers until your permanent ones are fitted. The temporaries allow you and Dr. Nancy Nehawandian to assess the look and fit of your veneers, ensuring your permanent veneers are comfortable and attractive.

Once your porcelain veneers are fabricated, you’ll come in for your second visit – the installation. The staff at Top Down Dental will clean your teeth with a special solutions that will help the adhesive form a durable bond. The veneer is cemented in place using an adhesive hardening light.

That’s it. Requiring little or no anesthetic, the whole process is quick, painless, and effective.

Full Mouth Reconstruction

A full mouth reconstruction is recommended when you have a collapsed bite. This means that your teeth are not properly meeting together and not properly supporting the lower third of your face. Your teeth may be worn, they may be lost, or they may just not be coming together properly. As a result, your teeth may be painful, your jaw may hurt when you bite and chew, you may have chronic headaches, and your face can look sunken and imbalanced.

With older techniques, where the mouth is restored one tooth at a time, it takes multiple visits, the old collapsed bite is duplicated, and the appearance of the face is not improved. Neuromuscular Dentistry allows Dr. Nehawandian to establish the most comfortable bite position using computerized neuromuscular technology. This includes tools to measure the movement and function of the jaw, including determining the stress in your muscles. We also use T-Scan, a digital tool that shows us exactly how much force your teeth are subjected to as you bite down. This allows us to ensure that every system from your muscles to your teeth are all working together in balance.

Dr. Nehawandian has received extensive training in full mouth reconstruction at LVI. It can dramatically improve your bite as well as the appearance of your smile and your face.

Ozone Therapy

Ozone can be thought of as an activated form of oxygen. Most oxygen is in stable molecules with two oxygen atoms, but ozone is a molecule with three oxygen atoms, which makes it unstable. As an unstable molecule, ozone wants to react with other molecules around it, especially organic molecules. This means that it is very good at attacking oral bacteria and killing it. Which makes it a great sterilization treatment in many environments.

Ozone is also a great sterilizer because as a gas it can penetrate into areas where we can’t clearly see, let alone shine a laser. And ozone has other valuable properties for certain applications.

Ozone Can Reverse Minor Tooth Decay
Tooth decay is caused by oral bacteria which excrete acid on teeth, removing vital minerals from the enamel or dentin. The minerals that make tooth enamel strong against pressure make it weak against acid. But ozone is a powerful treatment for reversing the process of decay.

Of course, when we blow ozone on an area impacted by decay, it kills the oral bacteria there, stopping current decay.

But as ozone decays, it doesn’t just turn into oxygen (which is deadly to many of the most harmful bacteria, but harmless to you) , it bonds with hydrogen atoms in the environment. Loose hydrogen is what makes a solution acidic, so as ozone is bonding with these hydrogens, it is neutralizing the acid and creating a basic environment.

In basic solution, the process of tooth decay reverses. The tooth takes minerals from saliva or from a mineral-rich formula we apply to the tooth, repairing the early stages of tooth decay. This stops or postpones the need for a dental filling.

Teeth Whitening

Why go pro?
There are many advantages to choosing professional tooth whitening treatments as opposed to home teeth whitening.

Professional tooth whitening treatments are very comfortable, safe and effective. If you have sensitive teeth and gums, you might experience discomfort or pain with home teeth whitening. A dentist can make custom trays to hold the whitening agent, causing less irritation. At Top Down Dental in San Jose/Los Gatos, we apply desensitizers for people who have very sensitive teeth and gums.
Professional whitening is quick and noticeable. If you are whitening your teeth for a wedding, graduation or other special event, you’ll appreciate how fast you’ll get your white teeth.
The results are controllable. Teeth whiteners only work on natural enamel. Without the color control of a professional tooth whitening treatment, your natural teeth may end up looking whiter that your crowns, white filling or implants. A professional treatment will give you more consistent results.


Straightening your teeth is a great idea. Not only will it improve the appearance of your smile, it will improve its health and efficiency, too. Straight teeth are easier to clean and they are more effective at chewing. But metal braces are not as good an idea. Although they are effective, introducing metal into your mouth for a year or more, and bonding brackets to your teeth is not an optimal solution.

Thankfully, there’s a better approach to straightening your teeth that we can offer you. Invisalign uses clear, BPA-free plastic aligners to push your teeth into position. These aligners are not only nearly invisible, they’re removable, so you can enjoy all your favorite foods, and don’t have to worry about cleaning around braces. And they’re more comfortable than metal braces, too.

I highly recommend Top Down Dental to anyone in search of the right dentist. Dr Nancy is a great dentist and all her employees are warm and friendly!

I was looking for a Biologic dentist to remove my root canal effectively and safely. Top Down Dental made the experience very pain free, by implementing many different relaxation techniques, which I completely appreciated. I was very happy with the work they did!

I started seeing Dr. Nancy after a recommendation from another fantastic dentist I know (who is now retired) from another state. When I started seeing her, I had multiple problems in my tooth due to an implant badly done. Dr Nancy was able to make me recover from that situation quickly and make recommendations which would make my general oral health much better in the long run. It was a complete 180 turn for me. I completely recommend this place. To top it all, the staff is amazing!

Dr Nehawandian and all of the staff are great. Our boys love that they get to watch movies during treatments, and the chairs have a massage option. We always feel welcome and pampered here. They get my highest recommendations.

I love Dr Nancy and her staff Vicky and Faye are the best all of her staff are accomdating and empathetic to my every request. I give the 10 Stars

I have been going to Dr. Nancy for over 18 years now and I have never thought about changing dentists. She is honest about your oral health and is truly committed to best serving your needs. Her skills are unique in that she is able to find a solution to any problem you may have. Unlike other dentists, she tries to solve the root of the problem instead of masking the pain.

Nancy has been my dentist for as long as I can remember! The office is great for kids and adults both; it has a calm, relaxed environment that has never made me feel anxious about going in for an appointment. The staff is all so friendly, and I always leave feeling great! Jenna is awesome
