Tooth Whitening

Tooth whitening refers to the use of concentrated bleaching agents applied to the surface of a tooth to lighten the colour. A consultation prior to treatment is recommended to discuss your expectations and current lifestyle, assess your dental history and determine the degree of tooth discolouration.

Common reasons teeth may be discoloured:

• Surface staining due to smoking
• Certain foods and beverages
• Presence of plaque or generally poor oral hygiene
• Medications such as antibiotics at a young age

There are two options foe whitening treatment, commonly referred to as “take-home” or “in-office”.

In-Office whitening procedure

A dental professional isolates your teeth from your lips and gums, and applies the bleaching agent onto the surface of each tooth. The gel used for this type of procedure is much stronger than the gel issued for the self-applied “take-home” system. Usually, a high intensity light or laser is used to strengthen the bleaching properties of the gel.

Initial results from the treatment are usually satisfying, however whitening treatments of any kind will often need to be followed up with periodical treatments to maintain the lighter colour. After a detailed assessment, a dentist cannot anticipate or guarantee an outcome. Side effects of teeth whitening may include sensitivity to temperature or air, tooth discomfort, or irritated gums. They usually subside soon after.

Toothpastes made for “sensitive teeth” are less abrasive and may provide relief. Oral health problems such as disease or tooth decay must be treated before whitening treatment can be recommended.
