Discolored Tooth 

Teeth naturally darken as you age.  But the overall color of your teeth should be about the same.  If a tooth is darker than those around it, that would be considered a discolored tooth.  In some cases, the discoloration may indicate decay or a dead nerve.  And these could lead to severe infection or loss of tooth.

What causes a discolored tooth?

Here are the following causes of a discolored tooth:

  • Decay
  • Trauma
  • Gum recession exposing a dark tooth root
  • A dead or receded nerve in the tooth
  • An existing root canal treatment
  • An old silver filling which has leeched gray color into the tooth
  • An old composite filling which is staining underneath the edges or has discolored over time
  • Tooth wear leading to the exposure of the darker layer of tooth under the enamel
  • Food or beverage stains

Who is at risk for a discolored tooth?

People who have the following:

  • Poor oral hygiene
  • Untreated periodontal disease
  • Existing root canal treatments and old fillings
  • Bite problems
  • Smoking
  • Consuming high-staining foods or beverages

What can I do to prevent my tooth from discoloring?

Here are a few recommended options:

  • Repair decayed teeth
  • Repair gum recessions that expose tooth roots
  • Replace old fillings
  • Correct bite problems
  • Bleach the inside of root canal treated teeth
  • Use dental whitening products
  • Avoid or reduce consumption of foods and drinks that stain (such as coffee and tea).  Immediately rinse your mouth with water when consuming staining meals.
