Some of the most popular smile enhancers on the market today are both over-the-counter (OTC) and professional teeth whitening products. And while studies indicate that bleaching can successfully achieve noticeable increases in whitening of stained teeth, there are some facts you need to know about these products and the results that they can deliver.
- Nearly all bleaching products contain the same basic ingredient, carbamide peroxide or its breakdown product, hydrogen peroxide. However, the products our office uses to professionally whiten your teeth are much stronger without compromising the health and safety of your teeth, gums, and mouth.
- OTC bleaches typically contain no more that 10% carbamide peroxide while professional bleaches can contain between 15% and 35%. And to make professional bleaching even more effective, we may use them in combination with specialized lights or lasers.
- Bleaching is NOT a permanent solution and thus results will diminish over time. The “fade rate” begins to occur 6 to 12 months after treatment.
- While you can't avoid the fading process, you can extend your bleaching results by avoiding foods and drinks that stain your teeth, such as red wine, red (tomato-based) sauces, coffee, tea, sodas/colas, and blueberries to name a few.
- Another method for extending your results is to use a straw when drinking beverages that can stain your teeth so that the liquid does not come in contact with your teeth.
- If you have visible crowns and/or veneers mixed with your natural front teeth, it may be quite difficult for you to bleach your natural teeth so that they perfectly match your veneers or crowns. Remember, tooth whitening is not effective on crowns, veneers, bridgework, or any type of artificial tooth.
- One of the most common side effects of whitening teeth is tooth sensitivity and irritation of the gum tissues. They both are usually temporary and often occur when you start bleaching; however, they generally subside after a few days.
Overall, bleaching your teeth is an effective way to brighten your smile with minimal side effects. If it is something you are interested in pursuing, talk it over with us first — even if you plan to use OTC products — so that you have a clear understanding about your specific options and projected outcomes.

We are often asked about the role the tongue plays with bad breath or halitosis, as it is known medically. The truth is that everyone will experience it at some point in life; however, there can be a number of reasons for its cause. Some of these include:
- Consuming odorous foods and/or drinks such as coffee, onions and garlic. This is usually just a temporary condition that can be resolved by brushing and flossing your teeth and using mouthwash. Also consider chewing gum containing xylitol, a sugar-free gum that both promotes saliva flow and reduces tooth decay.
- Diabetes, a disease caused by a faulty metabolism of sugar, as well as diseases of the liver and kidneys can also cause bad breath. Be sure to always let all your health care professionals know if you have any unusual symptoms or you been diagnosed with any of these or other illnesses.
- Poor oral hygiene, which causes gingivitis (gum disease), is one of the most common reasons for bad breath. And if your gum disease is progressive, you could eventually lose your teeth.
- If you use tobacco and regularly drink large amounts of alcohol, you are dramatically increasing the likelihood of having halitosis.
- And lastly, if you do not drink enough water to maintain proper hydration, you can develop bad breath.
There are more than 600 types of bacteria found in the average mouth, many of which can cause bad breath. And the back of the tongue is where these bacteria typically produce Volatile Sulfur Compounds (VSC), the culprits responsible for the worst odors attributed to halitosis.
As for cleaning your tongue, there are two common methods. You can use your toothbrush to brush your tongue, or you can use a tongue-scraper. The latter can generally be purchased at a drug or discount store. The keys to remember are that a clean, healthy tongue should be pink in color and not have a yellow or brownish coating.
If you have discolored teeth, the cause is often staining on the enamel surfaces from foods, beverages, or smoking. But tooth discoloration may also originate deep within the root of a tooth. Sometimes this happens to a tooth that had to have earlier root canal treatment because of injury or decay.
In such cases the living pulp tissue and its blood vessels and nerves had to be removed from the root canals, resulting in the death of the dentin layer, which makes up most of the tooth's body. Over time this caused the dentin to darken. The color may come from remains of blood that was left in the tissue, or from filling materials left in the root canal that are showing through.
Since these stains are caused internally (intrinsic) and not on the outside of the tooth (extrinsic) they must be whitened from the inside. This is usually done by putting a bleaching agent into the empty chamber from which the pulp was removed. Usually the bleaching agent is a substance called sodium perborate.
When it is mixed with a solution of hydrogen peroxide, sodium perborate slowly bleaches the color from the tooth's internal material. It is considered to be safe and reliable for this use.
The work begins by taking x-ray images to make sure that the root canal is correctly sealed and the bone is healthy. After this, we will make a small hole in the back of the tooth through which the root canal space will be cleaned. The root canal space will be sealed and the bleach will be applied in a putty-like form and sealed off from the rest of your mouth. Every few days this procedure will be repeated until the bleaching reaches the desired level.
At this point a tooth-colored composite resin will be used to seal the small hole that was made in the dentin to insert the bleach. After the tooth has reached the level of whiteness that matches it to your other teeth, veneers or crowns must sometimes be used to repair the surface if it is chipped or misshapen, for example.

A veneer is a thin layer of dental ceramic tooth-colored restorative material, usually made of porcelain, which replaces some of the tooth's enamel and is physically bonded to it.
You might want to consider porcelain veneers:
- If your teeth are severely discolored. (For best results we may recommend that your teeth be whitened before veneering them.)
- If your teeth cannot be evenly whitened or matched by other means.
- If your teeth are misshapen or worn, you can change their size or shape for optimum aesthetic appeal.
- If you don't want to have your teeth prepared (drilled), prepless veneers may be an option to change your smile.
- If you want as little natural tooth structure prepared as possible to improve your smile.
- If you would like something temporary first to “test-drive” your new smile, then:
- “Provisional veneers” allow you to try out your new smile and give us feedback before the final permanent veneers are placed.
- If you want to improve your smile for just one tooth or even multiple teeth.
- If you want long-lasting restorations — veneers can last from seven to twenty years or more.
And the top reason is:
- Porcelain laminate veneers are among the most aesthetic ways to create a more beautiful, yet normal, looking smile.
