genes affect our tooth colour

How Do Genes Affect Our Tooth Colour?

Teeth become stained for a variety of reasons and although genes influence how our body works, there’s still a grey area on whether discolouration is hereditary. Here’s what you should know.

Key takeaway:

  • Teeth can get stained due to smoking, ageing, medications, poor oral hygiene and diet.
  • There are genetic mutations that can cause teeth to weaken, appear blue, or feel sensitive to hot or cold temperatures.
  • Tooth discolouration can be treated through in-office and over-the-counter teeth whitening procedures.

Talk to your dentist before trying any tooth whitening products to ensure they are safe.
