Want whiter teeth?

There are a number of causes for tooth discoloration. We can separate them in to three categories: Extrinsic, Intrinsic and age-related discoloration.
  • EXTRINSIC or surface stains are mainly caused by food and beverages. The most common are coffee, tea, wine, and cola. Other stain causing substances are tomato sauce, berries and hard candy. Try to consume these in moderation, followed by water and/or brushing.
  • INTRINSIC discoloration is caused when the inner structure of the tooth (dentin) darkens or tints. This can be caused by trauma, certain medications or genetics.
  • AGE-RELATED discoloration is a combination of both intrinsic and extrinsic factors. The enamel on our teeth thins over time allowing the yellower dentin under it to show more.

    Appropriate treatment to achieve whiter teeth depends on the causes and extent. If you would like a brighter smile, be sure to ask us what can be done for you.
