Treating Different Types of Tooth Discolouration

Toronto Tooth Discolouration Treatment

For many patients, the colour of the teeth is a top concern. While most would love a bright, white smile, the reality is often a lackluster smile with teeth that are discoloured and stained. There are dental treatments, including teeth whitening, that can treat these stains and restore a bright shade of white to the teeth, but in order for treatment to be successful, it is important to understand what type of discolouration is present. Although the appearance of the teeth is likely to be affected in much the same way, it is important to understand that there are different types of tooth discolouration. By determining what type of discolouration is present, cosmetic dentist Sol Weiss can offer his Toronto patients effective tooth discolouration treatment.

Extrinsic Discolouration

Extrinsic stains are very common amongst our patients. These are stains that affect the outer layer of the teeth, also known as the enamel. There is a wide range of factors that can lead to the formation of extrinsic stains, including the following:

  • Deeply colorred foods and beverages (wine, coffee, cola, berries, etc.)
  • Smoking
  • Poor oral hygiene habits
  • Aging

Although extrinsic stains can have a significant impact on the appearance of the teeth, this type of discolouration is generally considered to be superficial, because it is easy to treat.

Treating Extrinsic Stains

Extrinsic stains respond very well to bleaching agents that are found in teeth whitening treatments. Over-the-counter products may offer some improvement, but for dramatic effects patients should consider professional teeth whitening. Dr. Weiss offers both in-office and at-home treatment options, both of which can improve tooth colour by up to 8 shades. Although teeth whitening is considered safe and highly effective for extrinsic tooth discolouration, patients may also consider dental bonding or porcelain veneers.

Intrinsic Discolouration

Intrinsic discolouration affects the inner layer of the teeth, also known as the dentin. If discoloured, the dentin can show through to the outer layers of the teeth, making the smile appear gray or yellow. The causes of intrinsic discolouration differ from those of extrinsic discolouration and include the following:

  • Overexposure to fluoride
  • The use of certain medications
  • Trauma or injury to the mouth or teeth
  • Wear and tear/aging

Intrinsic discolouration is the permanent result of one of the above circumstances, and is, therefore, not considered to be superficial.

Treating Intrinsic Discolouration

Because intrinsic discolouration comes from the center of the tooth, it is not responsive to the bleaching agents found in teeth whitening products. Rather than erase intrinsic stains or discolouration, Dr. Weiss treats this condition by concealing these flaws. Both dental bonding and porcelain veneers are excellent options for covering up intrinsic stains or discolouration in order to reveal teeth that are bright and white in colour. These treatments offer the added benefit of being able to address any other aesthetic imperfections that may be present.
