What Causes Yellow Teeth?

Yellow teeth or stained teeth are classified as either intrinsic stain or extrinsic stain in nature. An extrinsic stain is the most common type of stain. These are stains that occur on the surfaces of the teeth, usually on the front and sides of the teeth.

Common causes of Extrinsic Stains:

  • Coffee
  • Tea
  • Wine
  • Smoking


Intrinsic stain occurs on the inside of the teeth. This type of stain affects the dentin, which is the layer just under the enamel layer. Dentin is naturally darker than the tooth’s enamel, but it can be made even darker due to other factors.

Common causes of Intrinsic Stains:

  • Excess fluoride during the childhood years
  • Mother’s use of tetracycline medications during pregnancy
  • Use of Tetracycline during childhood
  • Damage or trauma to the teeth
  • Dentinogenesis imperfecta condition (gray or purple look)

What Is A Dental Veneer?

A dental veneer may also be called a porcelain veneer or dental veneer. It is a thin tooth-like shell or outer layer that fits on top of your existing teeth. The dental veneer is made to match your natural teeth’s shape and colour.

These thin dental veneers are bonded to the front of your existing teeth by first removing a small amount of the existing enamel, to make room for the veneer. They are used on the front teeth to enhance or freshen your smile.

Dental Veneers & Stained Teeth

Surface stains can be removed over time by having a dental cleaning, professional teeth whitening and maintaining proper oral care. Internal stains that have affected the dentin of the teeth, however, cannot be removed in the same way.

By using dental veneers to cover teeth with intrinsic or extrinsic stain, it is possible to enhance your smile completely. Dental veneers can also help to close gaps or spaces between teeth and even balance out your smile line.

If you would like to enhance your smile or whiten your teeth, dental veneers are a great option. Contact us for a complimentary consultation; we would love to discuss cosmetic dentistry options that suit your smile!
