Teeth Whitening: Frequently Asked Questions

Overview

Teeth whitening is one of the easiest ways to improve your appearance. Whiter teeth can boost your self-esteem and confidence. Years of drinking Coffee, tea, cola, red wine, and smoking eventually takes their toll on teeth. The results are dull, yellowish-colored teeth. Some teeth may have darker gray-colored stains due to antibiotics. Most teeth will benefit from tooth whitening. Teeth whitening is a proven safe and effective way to brighten stained, discolored teeth.

Your dentist has a variety of methods for restoring a bright white smile including porcelain veneers, composite bonding, implants and whitening, also known as bleaching. However, of all the advances made in dentistry to enhance the appearance of the teeth, whitening is the easiest and least invasive, and effective for 3 out of 4 cases. The procedure is safe, simple, and more affordable than ever before. Because of these reasons and more, whitening has become very popular.

Should I consult a dentist about teeth whitening?

You may want to start by speaking with your dentist. They can tell you whether whitening procedures would be effective for you. Whiteners may not correct all types of discoloration. For example, yellowish hued teeth will probably bleach well, brownish-colored teeth may not bleach as well, and grayish-hued teeth may not bleach well at all.

Bleaching may not enhance your smile in the event you have had bonding or tooth-colored fillings placed in your front teeth. The whitener will not affect the color of these materials and they will stand out in your newly whitened smile. You may want to investigate other options in this case such as porcelain veneers or dental bonding.

What teeth whitening methods are available to me?

All whitening products contain peroxide either as carbamide peroxide (CP) or hydrogen peroxide (HP). Peroxide dissolves the organic stains in the tooth to change the color and produce a whitened effect.

There are four types of peroxide-containing tooth whitening products available:

* In-practice products are applied by a dental professional. These products contain a high percentage of CP or HP and are applied directly to the teeth. Some activated by heat, light, or laser. This may be the product for you if you're in a hurry for whiter teeth and you don't have tooth sensitivity. For very dark-colored teeth, the whitening process can be sped up in two to three hours followed by a take-Home product until the desired whiteness is achieved.

* A take-home product supervised by a dentist is the most popular whitening method. These products contain a lesser percentage of CP or HP than in-practice products and are worn in a tray overnight or during the day at Home. A custom-fitted tray is made to hold the whitening product directly against the teeth while lessening its contact with the gums. Some products have fluoride added to help prevent or treat mild tooth sensitivities. The typical stains of ageing will whiten in seven to fourteen days when the tray is worn overnight.

* Over-the-counter (OTC) whitening products contain a small percentage of HP or CP. Caution should be used with these products as many contain an acidic solution that can wear away tooth enamel. OTC products use a bulky, one-size-fits-all tray to hold the product. Usually more product is swallowed than stays in the tray because of the trays poor fit against the teeth. It can take up to six months and the purchase of several kits to get whiter teeth. Flexible strips coated with whitening gel have recently been introduced as an OTC at-Home tooth whitening method. The strips are worn on the front teeth and folded over to keep them in place. Results are reported to be noticeable after fourteen days and effective for 6 months.

* Over-the-counter whitening toothpastes contain a small percentage of HP, CP, or polishing ingredient. The toothpastes are effective in keeping teeth cleaner and whiter looking but some may be very abrasive. The harsh abrasive will wear away the enamel with repeated use gradually making the teeth look yellow. Whitening toothpastes remove surface stains and prevent new stains from building up. Whitening toothpastes however aren't in contact with the teeth long enough to remove internal stains. Ask your dentist about the safety and cavity protection of specific toothpastes before you buy.
