What Do I Need To Know About Teeth Whitening?

What Do I Need To Know About Teeth Whitening?

With more and more teeth whitening products being available at local grocery stores, it’s important to decipher between the products that actually work and the products that are harmful to ones teeth. People often think that these products are just as good as the service dentists can provide and are actually putting their teeth at risk by treating them improperly. Looking for Teeth Whitening Services? Trust all of your dental needs with John Powers DMD and staff.

Why Do Teeth Turn Yellow?

There are actually two methods of whitening teeth when treated by a dentist and that is because there are two ways teeth can turn yellow or discolored.

Teeth actually yellows with age. Just as our hair turns gray as we grow older the inner part, or dentin, of teeth yellow over time. As teeth repair themselves for various reason, the dentin becomes darker. By wearing down the enamel of your teeth through other processes like grinding teeth, this will result in an overall yellowish look to teeth.

Other reasons why teeth can turn yellow include:

  • Taking tetracycline before age 10
  • Falling on or hitting a tooth
  • Too much fluoride (also called fluorosis)
  • Genetics, which determine the color of your teeth to begin with
  • Silver fillings

How does Teeth Whitening Work?

There are two methods of teeth whitening: intrinsic and extrinsic

Intrinsic

This process is the whitening of the inner portion of the tooth. Intrinsic Whitening soaks up hydrogen peroxide gel and helps lighten up the tooth. By whitening the inner part of the tooth, the color is reflected through the enamel of your teeth and makes them look whiter and brighter. It’s important to note a common misconception- bleach lightens the inner tissue of the tooth and not the hard outer enamel.

Extrinsic

This processing is removing the stain from the outer enamel of the tooth. These type of stains have been left by smoking, coffee, wine other substances that will stain teeth.

Which Teeth Whitening Technique Is Right For Me?

If you have intrinsic yellowing, no amount of stain-removing toothpaste can lighten the intrinsic color of the tooth. You’ll need to whiten your teeth using a bleaching gel that is held up against the teeth.

If you have extrinsic discoloration (i.e. staining from things like coffee and tea) it can be removed by cleaning the teeth with a professional teeth cleaning. Bleach will not work well on extrinsic discoloration.
