Yes, years of teeth whitening treatments by Dental Offices have proven that it is safe. If directions for use are followed, home application is also safe. If problems such as teeth sensitivity or gum irritations are experienced, the frequency of use should be reduced from every day to every other day. Some people experience mild to moderate teeth sensitivity however, it normally subsides quickly following completion of treatment.

2. How does the whitening treatment work?

A moldable "tray" or mouthpiece is submerged into hot water for 5 seconds until soft and a bite impression is taken. After shaping the trays for upper and lower teeth, the whitening gel, which contains active ingredient Carbamide Peroxide, is applied to individual trays and inserted into the mouth and over the teeth. One tray at a time is left in place for 20-30 minutes.

Extending treatment times for faster whitening may be alright if your teeth are not over-sensitive. As the gel is activated, a slight tingling or bubbling sensation may be felt, which is the oxidation process taking place. Treatment should be done on upper and lower teeth each day until desired whitening is achieved. Twice a day treatments may also, achieve faster whitening results if teeth and gum sensitivity is not apparent.

3. What occurs during whitening?

During the teeth whitening process, the active ingredient in the gel, Carbamide Peroxide, is broken down and oxygen enters the tooth enamel bleaching embedded discoloured substances (stains). The structure of the tooth is not changed; only the tooth enamel becomes a lighter and whiter shade. Fillings, crowns, bridges and bondings, etc. are not affected.

4. What is Carbamide Peroxide?

Carbamide Peroxide is the primary active ingredient or bleaching agent in the professional teeth whitening gel. It is essentially a variation of Hydrogen Peroxide and combined with the unique adherence properties of the specially formulated gel, it provides the chemical reaction required to safely whiten your teeth.

The Clinical Pharmacology Classification of Carbamide Peroxide states that there are "No significant interactions", although some teeth sensitivity or minor gum irritation may be experienced, which normally subsides after completion of treatment.

5. How long will it take until my teeth are whiter?

Whitening results often become apparent during the first few treatments, but typically a noticeable whitening effect becomes evident after about 8-10 treatments. Teeth will continue to whiten with each successive treatment until desired results are achieved.

Results vary, but in our experience backed by studies, show that 90 to 95% of people experience some level of whitening.

6. How long do results last?

For most people, the results are long lasting. Exposure to coffees, teas, tobacco, red wines and certain other stain producing substances will eventually darken teeth again over time.

After initial treatment, some people do touch-ups every 6-8 months based on the amount of stain producing substances that they are exposed to. The ProWhiteSmile Whitening System is not a "supermarket" type tooth whitening kit and is considerably stronger than most "As Seen On TV" type kits.

The active ingredient in the whitening gel, Carbamide Peroxide is in Professional Dental Office strength (23%) and our massive 10cc syringes give up to 40 individual tray treatments. 3 times the amount of most syringe type kits sold at higher prices.
