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.

Your smile is one of the first things people notice, but if your pearly whites have lost their luster, chances are you might be hesitant to show them. As we age, our teeth naturally darken, and certain substances can leave teeth stained or discolored, making you appear older. One easy way to turn back the clock is to have your teeth whitened; a safe, painless, and non-invasive way of achieving a young, healthy-looking smile.

Causes of Tooth Discoloration: Exposure to high-levels of fluoride and taking tetracycline antibiotics during childhood can stain the teeth's structure. Smoking cigarettes and using chewing tobacco can also cause tooth discoloration, as well as foods containing tannins such as red wine, coffee and tea. In addition, poor brushing techniques and not flossing regularly cause bacteria to build on teeth resulting in yellow stains.

The Whitening Process: Our office can help you to achieve a brighter smile using either an in-office procedure or an at-home whitening kit. We can help determine the best treatment for your budget, time frame and individual needs. If you choose to have professional whitening done in our office, we will utilize a prescription strength gel sometimes even activated by a concentrated light source. This procedure offers immediate and long-lasting results in less than an hour. After a single treatment, teeth are typically six to ten shades lighter and with proper maintenance, can last five years or longer.

At-Home Results: For those seeking more gradual results, another option is to use custom-fit trays, which our office will make for you to use at home to whiten your teeth. This is generally less expensive, and is very effective at lightening teeth several shades, although it may take a week or longer to see optimal results.

Choosing the Best Procedure: For some people, teeth whitening may not offer adequate results. If you have thin enamel, chipped, uneven or crooked teeth, we may recommend applying porcelain veneers to restore your damaged teeth. Veneers are bonded to the front of teeth to give your smile a straighter, more uniform appearance.

When asked about her dazzling white smile, Cat Cora, the first female iron chef on the hit television series Iron Chef America, freely admits to maintaining the brightness of her smile with professional whitening sessions.

“With what I do, whitening your teeth is like getting your hair done, your nails done and everything else you have to do to be on television,” Cat recently told Dear Doctor magazine. However, she does have her limits. “I want my teeth to be white and healthy looking — but not stark white or looking like they could glow in the dark,” she said with a laugh.

Cat's perceptions and experiences with tooth whitening may accurately describe Hollywood, but through the power of media, celebrities and their respective fan bases, having attractive white teeth has become a goal for most people. This is because white teeth are subconsciously associated with youth and virility.

Here in the dental office, we can use professional-strength “power bleaching” to whiten teeth several shades in a single visit. To prevent irritation to the area surrounding the teeth being treated, we isolate the gums and skin of the mouth with a protective gel or a rubber barrier known as a dental dam. After the whitening solution is placed on the teeth, the process may be supplemented by heat or a light source to activate or enhance peroxide release.

For bleaching teeth at home, our office can make custom-fitted bleaching trays that you fill with a gel form of carbamide peroxide. Sometimes this whitening gel can cause a temporary tooth sensitivity to hot and cold, but this normally lasts for no more than four days after you stop bleaching your teeth.

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.”
