Teeth Bleaching Results, Safety, and Risks – Your Questions Answered


Teeth whitening procedures give you back your radiant smile after unsightly stains take it away. Before you make an appointment with your dentist, it helps to be familiar with the process, and know what to expect. The following questions and answers may help you understand how the best teeth bleaching options work.

Does the Tooth Stain Color Matter? 

Stain color does have an effect on your results. Bleaching works best for yellow discoloration; it is less effective for resolving brown stains. Blue, gray, or purple stains are more difficult and may require additional treatment. Other factors that affect results include the condition of your teeth, the strength of bleaching agents used, and the duration of treatment.

Does Teeth Bleaching Carry Risks? 

Even the best teeth whitening procedures may cause minor side effects. The most common are tooth sensitivity and irritation of the soft tissues inside your mouth. Both symptoms disappear quickly. If they are severe, your dentist may be able to help relieve your discomfort.

Are Routine Touch-Ups Required? 

If you regularly consume stain-causing foods and drinks like coffee, tea and wine, your teeth bleaching results may not last long. Avoiding them, or maintaining your results with at-home products can help them last as long as a year without a touch-up.

Does Teeth Whitening Damage Existing Fillings or Crowns? 

Teeth bleaching products have not produced any damage to fillings or other restorations. However, tooth-colored crowns, veneers and bridges are not lightened during a tooth whitening procedure, so they may no longer match natural teeth that have been lightened.

Do Teeth Bleaching Products Harm Tooth Enamel? 

Ten-percent concentrations of peroxide contained in most over-the-counter teeth bleaching products have been shown to have little or no effect on tooth enamel.

Does Teeth Whitening Damage a Tooth’s Nerve? 

No evidence of damage to a tooth’s nerve by bleaching agents has ever been found.

Are Teeth Whitening Products Safe? 

Bleaching products sold through dentists’ offices and professional in-office systems have received the ADA Seal of Acceptance, which designates them as both safe and effective. With the exception of several teeth whitening toothpastes, over-the-counter whitening treatments have not received the Seal of Acceptance.
