SMILES ARE VALUABLE- When people are asked, “What would you like to improve most about your smile?” The most common response was: Whiter & brighter teeth.

In-Office Teeth Whitening:

Professional tooth whitening in a dental office is the preferred whitening method because even though stronger agents are applied, the rest of the mouth, including the gums, is protected from these materials. extremely effective,and can transform teeth in a single office visit. A special light or laser might be used to enhance the action of the whitening agent. Your teeth can literally brighten up to 10 shades in about an hour.

At-Home Bleaching :

Peroxide-containing whiteners actually bleach the tooth enamel. They typically come in a gel and are placed in a tray that fits on your teeth. The concentration of the bleaching agent is lower than in office teeth whitening Teeth Whitening Myth# 1: Harms the Enamel


Not generally true! Professional Teeth whitening productsuppliers mostly use Hydrogen Peroxide or Caramide Peroxide as the active ingredients in their tooth whitener gels. The chemical hydrogen peroxide (H-O) is a beaching agent which converts into water (H-O) and releases an Oxygen molecule (O) in the process of chemical reaction. Both Water and Oxygen are common , safe components of our everydaylives.

The Oxygen particles penetrate the rough surface of your tooth ( even though they appear smooth, they are microscopically rough rod like crystal structures) and dislodgestaining particles. I like to explain this imagining the TV commercials which show how a clothes washing powder with oxygen lifts stains from your clothing.

Teeth Whitening Myth# 2: Makes your teeth sensitive

Sometimes some amount of sensitivity can occur, but the magnitude of this varies from person to person. However, it just lasts for 24 to 48 hours.

Teeth Whitening Myth # 3: It is painful

Teeth whitening treatments are safe and painless. However, the bleaching agent may cause discomfort if it touches the gums. To avoid this the dentist applies a gel between the gums and teeth called gingival barrier which will prevent the solution from touching the gums.

Teeth Whitening Myth # 4 Oral Cancer

One of the most bizarre misconceptions .This is likely because there are chemicals that are used in the whitening agents, and a lot of people automatically associate chemicals with cancer. There is no scientific proof either.

Tips to Prevent Tooth Discoloration After TEETH WHITENING

Avoid stain-causing foods and beverages – coffee, tea, wine, sports drinks, hard candy, berries and tomato sauce are all foods that can cause tooth discoloration.

Use a straw – when drinking beverages, to keep stain-causing dyes away from your teeth.
Quit smoking , pan & tobacco.


If a person has caps (crowns) or laminates then those teeth will not get whitened. NOTHING LASTS FOREVER… The effect of teeth whitening does not last forever. It will last for eight months up to a year and then the teeth will gradually come back to its original shade
