TestYourKnowledgeFrequentlyAskedQuestionsAboutToothWhitening

What causes stains on teeth?

Staining can occur on the outside surfaces of teeth and is caused by foods such as red wine, coffee, and tea, as well as by tobacco use. They can also be developmental, affecting the structure of the teeth due to excessive fluoride levels or from tetracycline antibiotics given during childhood to name a few. Changes in a tooth's enamel or dentin during tooth formation, or as teeth age, can also cause discoloration.

What is going on inside a tooth's structure that makes it look stained?

Most of a tooth's covering (95 percent) is composed of highly mineralized enamel. The crystals of enamel are contained in a framework, or matrix, of organic matter. Dentists believe that various organic compounds that get into this matrix can cause staining.

How do whiteners work?

Tooth whiteners or bleaches expose the teeth to a peroxide compound. This creates reactive oxygen that breaks down highly colored organic compounds within the tooth's sub-surface matrix, making the tooth look whiter, but without changing its internal structure.

What professional in-office whitening techniques are available?

During treatment, a high concentration of peroxide solution in the form of a gel is applied directly on the teeth, often with activation by a heat or light source. These systems use custom tailored trays fitted to an individual's mouth. Silicone barriers or protective gels are used to keep the peroxide gel away from the gums or sensitive membranes in the mouth.

How are professional home whiteners different?

Home whiteners involve a less concentrated solution of peroxide in a gel form. It is delivered to the tooth surface by a bleaching tray that is custom-made in your dentist's office. Over-the-counter whiteners such as whitening strips or paint-on formulas can also be used, but they take longer and they're not as effective — the more diluted solutions are used for safety.

Can toothpastes really whiten teeth?

Mild abrasives in toothpastes clean surface stains but cannot change the underlying tooth color or remove significant staining.

How long do the results last?

Usually, the results last from six months to two years, but effects will diminish over time. You can make them last longer by avoiding the foods and habits that cause staining.

Are teeth whiteners safe to use?

Teeth whitening products are safe if used according to our recommendations or the product manufacturer's directions. Peroxide products may be toxic if used in excess of recommended intervals and amounts.

Christie Brinkley's world-famous smile has graced the covers of countless magazines for over 30 years. In fact, in her own words from an interview with Dear Doctor magazine, the supermodel said, “I think my smile was really my passport to success in the modeling industry.” And while most of her smile's appeal comes naturally, Christie does give it a boost with good oral hygiene, regular dental checkups and tooth whitening. As Christie says, “When it comes to teeth, keep it as natural as possible. Do not go overboard on whitening. You want your teeth to compliment your face…your friends should not be required to wear sunglasses when you smile!”

Aside from some potential minor side effects such as tooth sensitivity, whitening teeth through bleaching is a relatively inexpensive way to brighten your smile conservatively and successfully. There are three common methods, as described below:

  • An external or vital approach where “vital” (living) teeth are bleached through direct contact to the tooth's surface.
  • An internal or non-vital approach where the tooth is whitened from the inside during a root canal treatment.
  • A combination approach in which both internal and external bleaching techniques are used.

But what causes teeth to become discolored?

Tooth discoloration can be caused by a traumatic blow to your teeth resulting in nerve tissue (pulp) death. However, there can be many other causes: consuming or using products that stain the teeth such as coffee, tea, cola, tobacco products and red wine, to name just a few. Aging is another factor, as it results in changes in the mineral structure of the tooth as the enamel, the outermost layer, loses its beautiful and youthful translucency. Other causes include exposure to high levels of fluoride; tetracycline, an antibiotic, administered during childhood; inherited developmental disorders and jaundice in childhood; and tooth decay.

The good news is that we routinely brighten smiles through tooth whitening.

In modern society, a bright, white smile conveys optimal health, youth and sound teeth. However, various influences including age, wear, diet, and lifestyle may prevent you from having and maintaining the glistening smile you long to share with the world. Luckily, there are many safe, inexpensive, and successful treatment options for discolored or stained teeth.

We can perform a “power bleaching” in our office to whiten teeth that are severely stained or discolored. This procedure whitens the external surfaces of the teeth by using a high concentration (35-45%) hydrogen peroxide solution, which is sometimes activated by a specialized light. To prevent irritation of the mouth's soft tissue lining during this procedure, we will isolate your gums and membranes with a rubber dam, a silicone or other effective barrier. Professionally applied in-office power bleaching provides control, speed, and predictability capable of lightening teeth up to ten shades in an hour. Don't try this at home! Our staff will take precautions in the office to avoid side effects and possible tooth sensitivity.

We can also provide you with custom-made, vacuum-formed, plastic bleaching trays for use with a take-home whitening application. In this instance, a gel made from carbamide peroxide (4-7% hydrogen peroxide, safe for home use) is delivered to the tooth surfaces in the bleaching trays. You will need to wear the tray for 30 minutes twice a day, which is a longer process than in-office bleaching. The first subjective signs of whitening will occur after three or four sessions, allowing whitening of up to eight shade units.

Another home-based option, whitening strips, essentially look like band-aids for the teeth. They are capable of lightening teeth by about three shades after being worn directly on the surface of the teeth for 30 minutes twice a day for one week.

If you have always wanted whiter teeth, schedule an appointment so we can determine which of these treatment options would work best for you.

Vanna White has been a household name for the last 27+ years and is best known as the first female co-host of the game show, Wheel of Fortune. She radiates a warm, friendly, down-home appeal and says when describing herself, “what you see is what you get!” While this is quite true, there is so much more to her. She has received a star on the famous Hollywood Walk Of Fame, has starred in an NBC movie and written a book. She is even featured in The Guinness Book of World Records as TV's most frequent clapper, and most recently started her own line of yarn called Vanna's Choice with half of the proceeds going to St. Jude Children's Research Hospital. And while any one of these accolades could serve as the highlight of a lifetime for most, for Vanna they fall slightly short. Her favorite job is being mother to her son, Nicholas, and daughter, Giovanna.

The following are excerpts taken from an exclusive interview in Dear Doctor magazine, the premier oral healthcare resource for patients and consumers.

What is the secret to her dazzling smile?
Vanna's oral healthcare routine is the same today as it has been since her childhood — and one everyone can follow. She brushes her teeth at least twice a day (morning and at bedtime) and flosses her teeth daily. She also has strong feelings about flossing. “I think that flossing is the most important thing. I believe that dental floss helps a lot as it keeps your gums strong and looking younger.”

What about bleaching, has she done it?
Absolutely! Vanna bleaches her teeth once or twice a year to help retain her naturally white teeth and to offset any discoloration from coffee and an occasional glass of red wine. “I have done over-the-counter and professional bleaching, but I do like the trays my dentist made because they fit perfectly.” She also states, “Anything you can do professionally is probably better because I would assume that a dentist's ingredients are stronger than over-the-counter products.”

Has she had any cosmetic dentistry?
When it comes to answering a question about cosmetic dentistry, Vanna is just as open and honest as she is about everything else — a trait for which she is known. “I had a bridge put in probably 30 years ago, where I had a tooth pulled and there was a space. And I did have a little tiny chip on one of my front teeth years ago that my dentist fixed. But that is it. Again, I feel very fortunate to have good teeth. The braces [from her childhood] straightened them out and there has been no need for any cosmetics since then.”

Does she do anything to protect her teeth?
While she admits to occasionally forgetting to use her nightguard, a protective mouthguard worn during sleep, she firmly believes in their need. “I do sleep in a nightguard because I grind my teeth. I have a filling in the back that probably has been filled five times from grinding.” She added, “Both of my children do have mouthguards that they wear for their sports.”
