Tooth whitening is a cosmetic procedure that can help improve the appearance of teeth. It can be done at home or in a dentist's office.
At-home tooth whitening kits
At-home tooth whitening kits are available over-the-counter at drug stores and online retailers. These kits typically contain a whitening agent, such as hydrogen peroxide or carbamide peroxide, and a tray that holds the agent against the teeth. The tray is worn for a specified amount of time each day, and the whitening agent gradually lightens the teeth.
In-office tooth whitening
In-office tooth whitening is performed by a dentist. The dentist will use a stronger whitening agent than is available in over-the-counter kits, and the agent will be applied directly to the teeth. In-office tooth whitening typically takes one to two hours, and the results are immediate.
How long does tooth whitening last?
The results of tooth whitening can last for up to several years. However, the longevity of the results depends on a number of factors, including the type of whitening treatment, the patient's diet, and oral hygiene habits.
Side effects of tooth whitening
Tooth whitening can cause a number of side effects, including:
* Sensitivity to heat, cold, and sweets
* Toothache
* Gum irritation
* Dry mouth
These side effects are usually temporary and will go away within a few days. However, if you experience severe side effects, you should stop using the whitening product and see your dentist.
Who should not use tooth whitening products?
Tooth whitening products are not recommended for everyone. You should not use tooth whitening products if you have:
* Sensitive teeth or gums
* Tooth decay or cavities
* Exposed roots
* Gum disease
* Pregnant or breastfeeding
If you have any of these conditions, talk to your dentist before using a tooth whitening product.
Tooth whitening is a safe and effective way to improve the appearance of teeth. However, it is important to use tooth whitening products correctly and to be aware of the potential side effects.
