When it comes to dental discoloration, it’s fairly common that people end up with a yellow tint. The culprits for these stains can be easier to find, but what if your teeth are starting to look gray? This can leave you more confused about why it’s happening and what to do about it. Thankfully, your dentist can help you out. Here are common reasons that this flaw can develop and cosmetic solutions to consider.

Why Are My Teeth Looking Gray?

For some people, gray teeth can happen as they get older. It can be on just a single tooth or more, but these are some other reasons that may have led to this discoloration:

  • The tooth has died due to an infection or trauma. When this happens, the entire structure can turn into a dark bluish gray color.
  • You have metal in your restoration peeking through. A silver filling or crown can wear down and expose its more shiny parts the older they are.
  • You have dentinogenesis imperfecta, which is a hereditary tooth development disorder. It often makes your smile weaker and look blue-gray.
  • You were exposed to tetracycline during your childhood or in the womb. This is an antibiotic, but it can be the culprit. It also doesn’t respond well to whitening.

What Can I Do About My Gray Teeth?

Although your grin has a gray tint, there are ways you can correct the color. Your dentist is here to help give you back an aesthetic look with reliable solutions. These are popular cosmetic treatments you can consider getting:

  • Professional Whitening: This service is often the go-to for any type of discoloration. It uses high-quality bleaching gel that’ll brighten your teeth by up to eight shades. Again, it’s important to know that if tetracycline is the cause, then you might end up with uneven results.
  • Metal-Free Restorations: If you have an old crown or filling with metal in it, then you can opt to have it replaced with tooth-colored materials. Porcelain or composite resin versions are some that can be matched to your smile and blend in seamlessly.
  • Veneers: These are thin, durable shells that bond to the front-facing parts of your teeth. They effectively cover flaws behind them and transform the shape, shade, and size to your goals. Better yet, they can last up to 15 years with proper care.

In the end, a grey smile can leave you self-conscious, but your dentist is here to help. By talking with them, you can learn more about what’s behind your case and what treatments can give you the results you want.
