Tooth whitening lightens teeth and helps to remove stains and discoloration. Most dentists perform tooth whitening.
Whitening is not a one-time procedure. The outer layer of a tooth is called the enamel. Tooth enamel also contains pores that can hold stains.
The most common reasons for teeth to get yellow or stained are:
*Not taking good care of your teeth
It is also possible to have stains inside the tooth. These are called intrinsic stains. Teeth are still developing during these years. Trauma may also darken a tooth.
Tooth whitening is most effective on surface (extrinsic) stains.
Other dental problems can affect the success of tooth whitening. For example, cavities need to be treated before teeth are whitened. Whitening products will not make them whiter.
If you have tooth decay or receding gums, whitening may make your teeth sensitive. For in-office whitening, your dentist probably will photograph your teeth first. Next, the dentist or a dental hygienist will clean your teeth. For whitening at home, your dentist can make trays to hold the whitening gel that fit your teeth precisely. Vital whitening is performed on teeth that have live nerves.
Vital whitening may not improve the appearance of a tooth that has had root-canal treatment because the stain is coming from the inside of the tooth. Vital Whitening
The most common type of vital tooth whitening uses a gel-like whitening solution that is applied directly to the tooth surface. Tooth whitening can be done in the dentist’s office or at home. In-office (chairside) whitening allows your dentist to use a more powerful whitening gel. Then, the whitening agent, usually hydrogen peroxide, will be placed on the teeth.
After the whitening agent is applied, the dentist will shine the light on your teeth. A close fit helps the whitening agent remain in contact with your teeth.
Whitening toothpastes are available as well. Whitening is not a permanent solution. If you avoid these sources of staining, you may not need another whitening treatment for 6 to 12 months.
If you have a custom-made mouthpiece and whitening agent at home, you can whiten your teeth as frequently as you need to. Discuss your whitening schedule with your dentist. Women should not have their teeth whitened while pregnant. If you feel your teeth would benefit from whitening, contact your dentist to discuss the procedure.
Whitening treatments don’t yield permanent results. You worked hard to get your teeth white. Avoid the consumption of or exposure to products that stain your teeth. Gently brush from where the tooth and gum meet to the chewing surface in short (about half-a-tooth-wide) strokes. Brushing too hard can cause receding gums, tooth sensitivity, and, over time, loose teeth.
