Are cavities genetic?
Many patients wonder if getting cavities runs in their families or if it comes from their lifestyle.
The truth is, genetics can play a part, but cavities are mostly affected by how well you care for your teeth, your diet, and your dental habits.
At Junction Family Dental Care, we want to help you understand both the genetic and lifestyle factors that can lead to cavities, so you can better protect your smile.
Cavities, also called tooth decay, are a common dental problem around the world.
They happen when the hard outside layer of the tooth, known as enamel, gets worn away by acids.
These acids form when bacteria in the mouth break down sugars and starches from food and drinks.
Over time, this process creates small holes in the teeth.
Cavities happen when bacteria in your mouth create acids that wear away tooth enamel.
If you don't treat them, cavities can lead to pain, infections, and even tooth loss.
So, why do cavities occur? You might know that not brushing and flossing enough your teeth is a factor, but other causes include:
You can treat cavities in different ways, depending on how severe the decay is.
In the early stages, fluoride treatments can help strengthen enamel and possibly reverse damage.
For most cavities, dentists will remove the decayed part of the tooth and fill it with materials like composite resin or amalgam.
If the decay is more extensive, a crown may be needed to restore the tooth's shape and function.
When decay reaches the inner pulp, a dentist performs a root canal to remove the infection and save the tooth.
In severe cases, if the tooth can't be repaired, extraction may be necessary.
Are cavities inherited?
Yes, some aspects of cavities can be influenced by genetics. Here are a few ways this happens:
Some people naturally have weaker enamel, making their teeth more likely to decay.
Your genes may also affect how much saliva you produce and how well it protects your teeth.
If your teeth are crowded or have grooves, they might trap more food and bacteria.
Some people are more likely to have bacteria that cause cavities.
However, just because your parents had cavities doesn’t mean you will too.
It means you may need to take extra care of your teeth.
Genetics can play a role in dental health, but the environment usually has a bigger impact.
Brushing, flossing, and getting professional dental care can reduce most risks.
For instance, if you wear braces, you need to pay more attention to cleaning your teeth.
Your diet is also important.
Foods that are high in sugar and acid increase the chance of decay, while healthy foods and staying hydrated help protect your enamel.
Yes.
Genetics may influence your dental health, but your habits are what really matter to prevent any bad things from happening with your dental care, so:
Yes, children can inherit risk factors from their parents.
However, early dental care, sealants, and fluoride treatments can greatly lower the chances of decay.
We recommend bringing children in for their first checkup by the time they are one year old.
