Bright, white, and sparkling teeth improve your overall appearance. You may, however, notice stains or shades that are not typically yellow. Those stains are usually gray or blue. You may wonder about the reason your teeth get discolored this way. You will want to get a sparkling white color.
Here are some reasons for blue or gray teeth.
Natural tooth color
Natural teeth come in different shades and colors. According to Medline Plus, one of the reasons for the natural discoloration of teeth is a genetic condition known as dentinogenesis imperfect. This condition affects the appearance and structure of teeth. It can cause baby and adult teeth to have a blue-gray or yellow-brown color, and those teeth tend to be weaker than other teeth. This condition is also known as hereditary opalescent dentin, and it may be due to a genetic mutation that results in defective dentin. Be sure to discuss with your dentist for proper evaluation if you think you have this condition. Since this condition is rare, it is highly likely for your tooth discoloration due to some other reason.
Early antibiotic exposure
The Journal of International Oral Health suggests that exposure to the infection-killing antibiotic tetracycline at a young age can result in discoloration in adult teeth. The discolored teeth develop yellow-brown or blue-gray stains. These stains usually occur in horizontal patterns. While regular brushing and other daily care techniques won’t improve this discoloration, cosmetic whitening may work. You can discuss with your dentist the treatment that may work best for you.
Filling and other dental restoration can give your teeth a gray or blue appearance. Such an appearance can occur when you have an amalgam filling. This material usually has ingredients such as porcelain, acrylic, or ionomer. If your teeth appear gray or blue due to silver filling, your dentist may refill your tooth with white amalgam.
When teeth turn gray or blue, it might be due to the death of those teeth. Although all teeth appear lifeless, they contain living tissues in the form of nerves and vessels. This living portion of teeth is known as tooth pulp. The pulp of these teeth can die as a result of damage caused by trauma or illness. When that happens, the tooth may get discolored. If you think that one or more of your teeth have died, be sure to book an appointment with your dentist to discuss treatment options. While there is no way to revive a dead tooth, it can contain bacteria in the pulp chamber. This bacterial buildup can travel to the jawbone and cause an abscess, which can be severely painful.
If your dead tooth is getting discolored, your dentist will look for options to restore the looks of your smile.
Whitening gray or blue teeth
Although whitening treatments aim at bringing whiteness to yellowed teeth, some whitening options may help improve the appearance of naturally gray or blue teeth. Your dentist will give you details of results you can get from in-office or at-home treatment options. A whitening treatment can even improve the appearance of a dead tooth.
