Tooth whitening procedures and products have become increasingly popular over the last two decades. There are two main sources of application: professional procedures performed in a dentist’s office; and over-the-counter products for performing whitening applications at home. While there are pros and cons to both approaches, neither type poses a significant health risk — that is, if you match the correct product to the type of staining you have, and it’s applied according to the manufacturer’s instructions.
Although whitening treatments may differ in formula and strength, almost all use hydrogen peroxide as the bleaching agent, usually contained in carbamide peroxide which splits into hydrogen peroxide and urea upon activation. After many studies, there’s a strong consensus that hydrogen peroxide used at the levels found in whitening products doesn’t cause any harm to the body, including as a precursor to cancer.
But as the 16th Century Swiss physician Paracelsus once noted, “All substances are poisons… The right dose differentiates a poison from a remedy.” This is true of the chemicals that make up whitening products — they’re safe unless they’re overused. Going beyond their directions for use could lead to tooth enamel damage.
Further caution is also in order for teenagers using whitening products. Although they may have their permanent teeth (although younger teens may still have some primary teeth), the enamel layer is still developing and can be more vulnerable to damage from whitening chemicals than for adults.
The best approach for both a professional or home whitening procedure is to first seek consultation from our office. If nothing else, you should at least undergo a dental examination to identify the true cause of your teeth’s staining or discoloration. If the discoloration originates within the tooth, home applications and many professional treatments will not help if they bleach the outer surface only. We can also advise you on the proper application and dosage for a chosen product.
Using the right whitening product and in an appropriate manner will reduce the risk of injury to your teeth and overall health. And, the end result can be a brighter, more vibrant smile.

There are a number of materials and techniques available in cosmetic dentistry that help us improve our patients' smiles. Porcelain veneers stand out as one of the most popular and least interventional of these options.
As the name implies, a veneer is a thin layer of dental restorative material that covers the original tooth surface. Veneers don't require an extensive amount of tooth preparation or removal of sound tooth structure, as with a crown or bridge.
Veneers are made of dental porcelain, a material compatible with living tissue and with a very life-like appearance. The dentist as artist can fashion the porcelain to precisely imitate an individual's natural teeth, including the natural color and hue of surrounding teeth.
Are porcelain veneers an option for you? Only a smile analysis in our office can determine that. Your teeth must be in a somewhat normal position. The teeth in question must have a sufficient amount of remaining tooth structure to support veneers. And you must have symmetrical gum contours that will allow for proper framing of the teeth, which will enhance the final cosmetic result.
If your current dental health meets these criteria, then porcelain veneers could help correct spaces between teeth that aren't too wide, improve poor color, or address poor shape, contours or minor bite problems. Veneers, however, do have their limitations. They aren't effective if you have poor tooth position, if the root positions are widely out of line, or if you have a poor profile. Some form of orthodontics may be needed initially for these situations.
That being said, porcelain veneers are an excellent long-term option in the right situation. Depending on your individual circumstance and how you care for your teeth, a veneer application can last for several years, or if they come loose or become chipped they can be repaired in most cases. The material is strong enough to withstand normal pressures exerted during chewing or biting, as long as you avoid activities like opening nutshells with your teeth or chewing on very hard candy.
Overall, porcelain veneers can give your smile a whole new look with little impact on your remaining tooth structure.

Dental professionals sometimes use specialized words, and you may not be clear about exactly what we mean. Test yourself on some of the specialized vocabulary concerning tooth whitening. How many of the following can you define correctly?
A method of making yellow, discolored teeth whiter. It is relatively inexpensive and safe, with few side effects.
2. External or extrinsic staining and whitening?
Extrinsic staining mainly results from diet and smoking. For example, foods such as red wine, coffee and tea can produce extrinsic stain. Teeth with these stains are bleached by placing whitening substance in direct contact with the living tooth surface.
3. Internal or intrinsic staining and whitening?
Intrinsic tooth discoloration is caused by changes in the structure of enamel, dentin, or pulp tissue deep within the root of the tooth. When the discoloration originates with the pulp tissue, root canal treatment may be needed to whiten the tooth from the inside.
4. Chromogenic material?
Color generating material that may get incorporated into the tooth's substance. It can be a result of wear and aging, or can be caused by inflammation within the tooth's pulp.
5. Carbamide Peroxide?
A bleaching agent discovered in the 1960s and frequently used for tooth whitening. When used, carbamide peroxide breaks into its component parts, hydrogen peroxide and urea, which bleach the colored organic molecules that have been incorporated between the crystals of the tooth's enamel.
6. Power Bleaching?
This technique is used for severely stained tooth. It uses a highly concentrated peroxide (35 to 45 percent) solution placed directly on the teeth, often activated by a heat or light source. This must be done in our office.
An antibiotic used to fight bacterial infections. It can result in tooth staining when taken by children whose teeth are still developing.
8. Rubber Dam?
Use of strong bleaching solutions requires protection for the gums and other sensitive tissues in your mouth. This is done using a rubber dam, a barrier to prevent the material from reaching your gums and the skin inside your mouth. Silicone and protective gels may also be used.
9. Whitening Strips?
Strips resembling band-aids that you can use in your home to whiten your teeth. They generally contain a solution of 10 percent or less carbamide peroxide gel. When using them, be sure to read the directions and follow them strictly to avoid injury or irritation.
10. Fade Rate?
The effects of bleaching may fade over time, from six months to two years. This is called the fade rate. It can be slowed down by avoiding habits such as smoking, along with food or drink that causes tooth staining.
The “Hollywood Smile” — dazzlingly white — is associated in our society with youth, health and vitality. Achieving that smile through either professional or home whitening applications has become very popular.
Teeth become discolored or dull for a number of reasons. It can be something intrinsic with the teeth — changes in enamel or dental structure during development, inherited disorders, heavy exposure to fluoride or tetracycline, or changes in mineral structure or wear due to aging. It can also be extrinsic, resulting from environmental or lifestyle causes. Eating foods with tannins (red wine, coffee or tea) or carotene pigments found in plant foods like oranges or carrots, or using tobacco may all cause staining.
Most modern applications involve an oxidizing chemical (usually hydrogen peroxide) that bleaches the teeth. Professional applications in a dentist's office use high concentrations of hydrogen peroxide (usually 35 to 45%) applied directly to the teeth with control measures to protect the lips and gums. This type of application can lighten the color of teeth up to ten shades.
There are a number of home options too: whitening strips, “Paint on” or “Brush on” whitening, and even whitening gum. We can also provide you with a “Take home” kit that resembles the professional application but is generally less expensive. Although all these home applications are generally safe and effective, they typically take longer for results (several repeated days as opposed to about one hour for an office application), and not always to the same level of lightness as the professional.
Just about anyone can be a candidate for a whitening application. However, if you have thinner than normal dentin and more porous enamel, or suffer from gum recession or enamel loss, then whitening may increase tooth sensitivity. And, whitening is not a permanent solution: the brightness will fade over time, usually within a year. You can slow the fading by avoiding foods and habits that contribute to staining. It's also possible to touch up the initial whitening once or twice a year to extend the life of your new, bright smile.

Nothing conveys confidence quite like a bright, white smile. Unfortunately, not all smiles are created equal. And, some smiles are much whiter than others. Whether your teeth have become discolored from food and drink or general wear and tear from aging, you may find yourself looking in the mirror one day wishing that there was a simple way to enhance your smile.
You've probably seen many over-the-counter products that claim to whiten your teeth. However, the strongest and fastest whitening solutions are those that are available in our office. There are many reasons why a professional whitening treatment might be the right solution for you. Here are a few:

If you cringe at the appearance of your less than pearly whites when you look in the mirror, you are not alone. A frequently requested cosmetic procedure, teeth whitening is a very successful and relatively inexpensive way to enhance your smile. We can determine which whitening treatment will work best for you after performing a basic oral examination in our office. When will it work and when won't it? Here's some background:
Teeth most commonly become stained or discolored due to surface (extrinsic) changes, the most common of which are dietary and smoking. Foods including red wine, coffee, and tea can cause extrinsic staining. Teeth can also commonly become discolored or stained due to intrinsic (internal) reasons, such as changes in the structure of enamel or dentin or by incorporation of chromogenic (color generating) material into tooth tissue during formation or after eruption.

Thanks to technological advances, today there are more than 40 types of traditional or standard implants. A traditional dental implant actually replaces the root of a tooth, upon which a crown is built — the part you see in the mouth. There are 2 others types that are quite similar to standard implants. Mini implants are most like traditional implants except they are smaller in diameter. Micro-mini implants are an even smaller variation with an even narrower, more screw-like appearance. Micro-mini implants are also designed to be used on a temporary basis, thus can easily be removed. Together all of these types of implants provide us with a wide variety of options for permanently replacing missing teeth.
The following list details the types of implant restorations:
It is always good to be prepared before you have any dental or medical procedure. Make sure that you are informed and know what to expect to make you as comfortable as possible. We recommend that you have a list of questions with you to ask us during your consultation. If we inform you that you need a crown, consider asking any or all of the following questions:
