Tooth discoloration can be annoying. There’s just something about a yellow, tarnished smile that can make you hesitant to “open up.” But if your teeth are specifically turning gray, you might be a bit worried – and have a ton of questions! This post will not only explain what could be going on, but will also tell you how your dentist can help. Keep reading so you can get to the bottom of this pesky problem.

Why in the World Are My Teeth Gray?

Let’s address the elephant in the room: teeth “going gray” is not the typical result of everyday staining. There most likely is a special circumstance that’s causing your smile to be tinted by this hue. For example, you might:

  • Have had exposure to tetracycline. This antibiotic is known for causing gray dental discoloration in children younger than eight, or in cases where the mother took it during pregnancy.
  • Have a metal restoration. Fully or partially metal fillings and crowns can make your tooth look blueish-gray over time.
  • Be taking root canal medication. Ledermix and Ultracal XS can produce gray-brown tones in your dental enamel.
  • Have a troubled tooth. Physical trauma can cut off blood flow to your tooth, in which case it might look less than white.
  • Be influenced by genetics. Certain hereditary disorders, like dentinogenesis imperfecta, can affect the color of your teeth.

Never Fear – Your Dentist Knows What to Do

To solve your little “gray problem,” your dentist will first have to identify the reason why it became discolored. If its due to physical trauma, they may have to perform a root canal to remove infected or “dying” material. Otherwise, a teeth whitening treatment or customized dental veneers could have your smile looking good as new! Professional teeth whitening methods are far more effective than any solution you’ll find in stores, and veneers can conceal stubborn discoloration with a perfectly pearly facade.

In any case, it’s a good idea to have your grayish tooth examined by your dentist. On the off chance physical trauma has stopped blood flow and damaged the inner layers, it’s crucial to receive a root canal ASAP. Even if this isn’t the case, the sooner you can address unpleasant dental shading, the sooner you can restore your confidence in your smile!
