Why are some people more prone to cavities? Ask our dentist!

One of the most frequent questions patients ask our friendly family dentist at is why some people seem to get more cavities than others. Even among people who follow similar oral hygiene regimens, the amount of tooth decay varies. So, why exactly does this occur? We’re more than happy to provide some possible reasons.

Sometimes the answer is simply genetics. Some people are born with a susceptibility to certain types of bacteria that causes tooth decay, meaning the erosion of the hard enamel that protects the outer portion of the teeth.

The shape of your teeth, which is unique to each individual, also can be a factor in tooth decay. Crowded teeth present plenty of hiding places for bacteria, and for a sticky coating of plaque to build up. 

If you have spaces between your teeth, that provides a convenient place for food particles to linger. Teeth with lots of ridges or grooves can also be landing spots for bacteria. 

Saliva is the first line of defense against plaque and bacteria, so the amount and type of saliva your mouth produces can have an impact. And, let’s not forget about diet! A balanced, nutritious diet that limits sugary and highly acidic foods and beverages is a major difference-maker when it comes to the frequency of cavities. 

So, as that old song goes, the fundamental things apply: Take a stand against tooth decay by brushing with a fluoride toothpaste twice daily; floss or use an interdental cleaner at least once a day; visit our dentist regularly for professional cleanings and exams; and ask us about supplemental fluoride treatments and dental sealants if you are particularly prone to cavities.
