Why Do Teeth Darken?

Stained and darkened teeth can compromise an otherwise attractive smile. While teeth whitening can solve most cases of discoloration, understanding why teeth darken at all is important if you want to avoid letting your teeth get stained again in the future.

Teeth can darken due to several different factors, such as:

  • Food and drink – Coffee, wine, tea, soda, and certain fruits and vegetables can easily stain teeth if they are consumed on a regular basis.
  • Tobacco – Nicotine is one of the most common causes of dark teeth stains.
  • Poor dental hygiene – If you fail to brush and floss regularly, plaque and other staining substances can build up on your teeth, causing discoloration.
  • Age – Your enamel will start to wear away as you get older, eventually revealing more of the yellowish dentin layer of your teeth.
  • Medication – Antibiotics like tetracycline and doxycycline can discolor teeth if they are given to children before the age of 8. Certain antihistamines (like Benadryl) can also cause discoloration.
  • Disease – Some diseases affect your teeth’s enamel and dentin layers, making them yellow. Disease treatments like chemotherapy can also affect tooth color.
