There are a number of ways that a dentist can help whiten teeth, but in today's society, professional teeth whitening is the most popular option. This professional alternative is a method of whitening teeth utilizing a special gel and a special light. There are many, however, who question exactly how this works and what they will get from it. Below are some of the most frequently asked questions about teeth whitening.
Q: How does teeth whitening work?
A: It's important to note that
professional teeth whitening works only for those who have extrinsic stains, which are stains that are on the teeth thanks to an outside influence, such drinking a great amount of coffee or dark soda. Professional teeth whitening works by using a form of hydrogen peroxide that is applied to the teeth. The light that is used allows the peroxide to break down into radical hydroxyl ions which then travel into each tooth to break down the stains.
Q: Are there different methods available to whiten my teeth?
A: Absolutely. The most common is a laser or LED light-activated bleaching, simply because it has shown the greatest results in the least amount of time. There are, however, also non-light activated bleaching efforts which can take place in the dentist's office, and deep bleaching which is a combination of an office visit as well as an at-home product. You can also find teeth whitening kits that you can purchase in the store.
Q: How long is teeth whitening good for?
A: This is a very difficult question to answer because everyone is so different. Those who have had teeth stains due to the over-consumption of tea, wine, or coffee, and who do not change their habits, will likely find that their procedure doesn't last long at all. On average, teeth can stay bright with a professional teeth whitening anywhere from five to seven years. After that time, the procedure can be done again and the teeth can be re-whitened with no harm coming to them or to the person who happens to own the teeth.
