Understanding the Teeth Whitening Process: How Does It Work?

If you’re looking for a way to improve your smile, teeth whitening may be the answer for you. Teeth whitening is a safe and effective way to remove stains and make your teeth look whiter.

There are two main types of teeth whitening: professional teeth whitening and at-home teeth whitening.


  1. Professional Teeth Whitening

Professional teeth whitening is done by professional teeth whitening specialists. The specialist will use a whitening gel that contains hydrogen peroxide or carbamide peroxide. The gel is applied to your teeth and then activated with a light. The light helps to break down the stains in your teeth, making them look whiter.

Professional teeth whitening is typically more effective than at-home teeth whitening. It can also produce results more quickly. However, professional teeth whitening is also more expensive.


  1. At-Home Teeth Whitening

At-home teeth whitening kits are available over-the-counter or from your professional teeth whitening specialists. These kits typically contain a whitening gel and a mouthguard. You apply the gel to the mouthguard and then wear the mouthguard for a certain amount of time each day.

At-home teeth whitening is less expensive than professional teeth whitening. However, it is also less effective. It may take longer to see results with at-home teeth whitening, and the results may not be as dramatic.


How Does Teeth Whitening Work?

The active ingredient in most teeth whitening gels is hydrogen peroxide or carbamide peroxide. These substances work by breaking down the bonds that hold stains to your teeth. Once the bonds are broken, the stains are released and can be washed away.

The light that is used in professional teeth whitening helps to activate the hydrogen peroxide or carbamide peroxide. This makes the whitening process more effective.


How Long Does Teeth Whitening Take?

The amount of time it takes for teeth whitening to work depends on the type of teeth whitening you choose. Professional teeth whitening can take anywhere from one to two hours. At-home teeth whitening can take anywhere from two to four weeks.


How Long Do the Results Last?

The results of teeth whitening can last for several years. However, the color of your teeth can gradually darken over time. You may need to have your teeth whitened again every few years to maintain the results.


Is Teeth Whitening Safe?

Teeth whitening is generally considered to be safe. However, there are some risks associated with it. These risks include:

  • Sensitivity to hot and cold
  • Gum irritation
  • Tooth sensitivity
  • Discoloration of the gums
