What is professional teeth whitening?

Professional teeth whitening uses whitening agents provided or supervised by a dental professional to lighten certain types of tooth discoloration. Depending on the dental practice, treatment may be performed in the office, through a dentist-supervised take-home system, or with a combination approach.

How do I know if my teeth can be whitened?

Suitability depends partly on why the teeth are discolored and whether you have cavities, sensitivity, gum problems, or visible dental restorations. A dental evaluation can help determine whether whitening is appropriate and what results may reasonably be expected.

Does teeth whitening work on crowns or veneers?

Crowns and veneers generally do not respond to whitening in the same way as natural tooth structure. This can create a shade difference if surrounding natural teeth become lighter, so existing restorations should be considered before treatment begins.

Can teeth whitening cause sensitivity?

Some people experience temporary sensitivity during or after whitening. The likelihood and intensity can vary. Patients who already have sensitive teeth should discuss this with their dentist before treatment and ask about appropriate ways to manage it.

How long does professional teeth whitening last?

There is no single duration for everyone. Diet, tobacco use, oral hygiene, the original cause of staining, and maintenance can affect how long teeth retain their lighter appearance. Some patients may consider future touch-up treatment.

Is professional teeth whitening covered by dental insurance?

Whitening performed primarily to improve appearance is commonly considered an elective cosmetic treatment, so coverage may be limited or unavailable. Insurance policies differ, and patients should verify benefits directly with their insurer and dental practice.

Why is one of my teeth darker than the others?

A single dark tooth can have a different cause from general surface staining. Rather than simply whitening it, a dental evaluation can help identify why its color changed and which treatment options may be appropriate.

Should I get my teeth cleaned before whitening?

Professional cleaning and whitening serve different purposes. Cleaning removes plaque, tartar, and certain surface stains, while whitening changes tooth color. A dentist can determine whether cleaning or other dental care should occur before whitening.

Can yellow teeth become white again?

Some yellow discoloration may respond to whitening, but results vary according to the cause and natural tooth color. Whitening also has limitations, so treatment should not be expected to produce the same shade for every person.

Will whitening make my fillings look darker?

Whitening does not normally lighten tooth-colored restorations the same way it lightens natural teeth. A restoration that previously matched may therefore appear relatively darker after surrounding natural teeth become lighter.
