If your smile has ever been a source of insecurity for you, you’re not alone. According to research done by the American Association of Orthodontics, more than one-third of American Adults are unhappy with their smiles. For some, even whitening kits may not be enough to turn their yellow grins white. In fact, for some patients, their tooth discoloration may be genetic.

Continue reading to learn more about the genetic factors that can influence the color of your teeth.

1. Genetics and Tooth Enamel

The natural color of your teeth is determined by the thickness of your tooth enamel and the shade of dentin underneath. These traits can be passed down through generations. While genetics contribute to the baseline color of your teeth, it’s important to note that lifestyle factors also play a significant role.

Consumption of tea, coffee, and wine as well as acidic foods can also wear down and stain your enamel.

2. Hereditary Conditions That Change Tooth Color

Natural tooth color isn’t the only thing that can be determined by your genetics. Some disorders can also be passed down from parents to children. Here are two that can specifically affect the color of your teeth:

Dentinogenesis Imperfecta – This is a rare condition that affects the formation of dentin, the support structure of your teeth. It causes transparent tooth enamel and weak, easily cracked teeth.

Amelogenesis Imperfecta – This condition affects the enamel of your teeth rather than the dentin. It causes abnormal formation of the enamel, causing yellow-brown discoloration and small, discolored, pitted, grooved teeth that are prone to damage.

3. How to Treat Genetic Tooth Discoloration

While the genetic conditions listed above need to be treated with cosmetic or restorative dentistry, genetically yellowed teeth can be responsive to whitening treatments. It’s important to note that while over-the-counter kits can be used for this, they will not yield strong, lasting results.

Instead, it’s best to have your teeth whitened by a professional with stronger whitening agents. The chemicals that dentists use penetrate deeper into teeth to leave behind brighter, whiter teeth that last.

If you’ve been considering whitening treatments, now may be the time to schedule a consultation. A brilliant white grin awaits you, all you have to do is pick up your phone and start the process.
