Genes are responsible for so many things about our health and our bodies that it seems only natural to assume that they play a role in the well-being of our teeth. Those of us with cavities and gum disease may be wondering if genetics are partly to blame for why we’re having so many issues in that department.

The answer does have a lot to do with genetics but not in the ways you might think.


One of the most important components of your teeth is the enamel layer. This acts as a barrier of sorts to keep teeth strong and protected. But not all of us have the same enamel and genes. Much like with fingerprints we all have our own unique version and where enamel is concerned, some of us have much thinner enamel than others.

Those with thin enamel are more susceptible to experiencing some form of tooth loss and the condition of that protective layer is determined by genetics. In this case, if enamel is the problem, it can be blamed on bad genes.


Genes play a substantial role in your urges for sugary sweets. This may sound strange but it’s true. If you are more inclined to reach for chocolates, sodas, and other potentially damaging foods capable of rotting your teeth, the decision you’re making is predicated on your genetic makeup.

So those of you with a sweet tooth picked it up from your parents. Eating these foods on a routine basis is something you can blame on bad genes. That’s why it’s up to you to make the right decisions about your eating habits and, while genetics are a factor, the ultimate choice is yours when it comes to finding something to eat.


There is some good news. Just because you may be at a disadvantage where genetics are concerned, doesn’t mean you can’t avoid the dental dangers that come with them. It all starts with adopting strong brushing and flossing habits. If you are genetically predisposed to a preference for indulging your sweet tooth, you need to make up for it by being extra diligent about your dental hygiene practices.

Brushing and flossing are only one piece of the puzzle. Setting up regular dental appointments is also important for maintaining excellent dental health and for those individuals with bad genes, this can provide the best advantage for keeping their smile looking and feeling its best.
