Though everyone wants a beautiful, bright smile, you may eventually experience tooth discoloration in an unfamiliar shade. Instead of a yellowish hue, your teeth may appear to be a gray color. There are various reasons why this can occur, but there are also a variety of ways to correct this issue and whiten your smile. Here are some of the things that can cause gray teeth in Lincoln Park and how your dentist can help you fix them.

Dental Restorations

If you have amalgam fillings, silver or gold crowns, or another metal dental restoration, this may cause your teeth to turn a blue or gray color. This issue is more common with older dental restorations, and they can usually be with a new one made from natural-looking dental porcelain to give the teeth a more natural appearance.


According to the Journal of International Oral Health, exposure to a common infection-fighting antibiotic called tetracycline while in the womb or as a child can lead to discoloration in adult teeth. The affected teeth will develop bluish-gray or yellowish-brown stains, which often appear in horizontal stripes.

Dentinogenesis Imperfecta

A rare hereditary disorder called Dentinogenesis Imperfecta can make both baby and permanent teeth appear to give off a blue or gray hue. This disorder also causes the teeth to become weaker than usual, which makes them more prone to damage.


As we age, our teeth become discolored due to both natural and external causes. This may lead to them appearing to be more of a yellow or grayish-blue color.

Dead Teeth

If only one or a couple of your teeth turn a blue or gray color, this could be a sign that the teeth have died. Dead teeth can be caused by anything that cuts off blood flow to the tooth. Since it can take several years for trauma to the tooth to result in a color change, people may not even be aware of what led to the discoloration.

Treatments for Gray Teeth

Some of the treatments your dentist may recommend to correct gray tooth discoloration include:

  • Professional teeth whitening – If the tooth discoloration is only on the surface, professional teeth whitening may be just what you need to renew and revitalize your smile.
  • Dental veneers – These porcelain shells are placed over the front surface of the teeth to cover up imperfections like cracks and minor misalignments. They can also make your smile appear whiter and more uniform
  • New restorations – If the graying of your teeth is due to old dental restorations, your dentist may be able to replace them with tooth-colored ones that won’t cause the same issues.

Though tooth discoloration is a common issue, there are several ways your dentist can correct them. They can also help you get to the root of the problem and come up with a treatment plan to keep your smile looking lovely!
