Can Genetics Affect Your Tooth Color?

Millions of people are unhappy with their teeth. Why? In most cases, it’s because of staining and discoloration. After all, a smile is the first thing most people notice when meeting someone new. When it’s not perfect and brilliantly white, it can be a source of insecurity rather than confidence. Unfortunately, some cases of stained teeth will not respond well to teeth whitening – and that could be because of genetics.  Read on to learn how genes can affect tooth color and what your dentist can do to treat it.

Why Do Teeth Yellow?

Tooth staining and discoloration are completely normal occurrences that happen for several reasons. Usually, it’s the result of lifestyle factors like consuming dark-colored beverages and using tobacco products. But for some people, genetics can play a significant factor in influencing the color of their teeth. Thicker, white enamel can run in families, just like more transparent tooth enamel can be inherited. Since the layer underneath the enamel (dentin) is yellow, thin enamel exposes it more, creating a yellowed smile. That said, even if you take excellent care of your teeth, genetic pre-determination can still make them appear discolored.

Genetic Conditions That Can Cause Tooth Discoloration

Let’s take a look at two inherited conditions that can cause genetic staining and discoloration.

Dentinogenesis Imperfecta

This genetic condition causes grayish, transparent tooth enamel and weak, brittle teeth. Since the teeth are weaker than usual, they’re more susceptible to rapid wear, breakage, and loss. Dentinogenesis imperfecta can affect both baby teeth and permanent teeth.

Amelogenesis Imperfecta

This is another inherited condition caused by genetic mutations, characterized by abnormal enamel formation. Amelogenesis imperfecta creates yellow-brown tooth discoloration and soft, fragile enamel that is more prone to damage. Unfortunately, those with this condition are at an increased risk of tooth decay and damage (i.e., chipped, cracked, broken teeth).

How to Treat Genetic Tooth Discoloration

If genetic tooth discoloration doesn’t respond well to teeth whitening, how can the color of your smile be improved? Luckily, there are many ways you can treat genetically stained teeth!

• Teeth Whitening – Although most store-bought whiteners won’t be able to give you your desired results, bleaching performed by a dentist can be much more effective. They’ll use powerful products that are guaranteed to brighten your smile in no time! Plus, you can enjoy your stunning results for a long time.
• Tooth Restoration – Those with genetic conditions that cause weak, discolored teeth may opt for tooth restoration. Crowns, veneers, and dental implants can not only improve your appearance, but your oral health as well.

Ultimately, good oral hygiene and a healthy lifestyle are the best way to keep your pearly whites shining bright for as long as possible – no matter what your genes say!
