Why do Some People Always Get Cavities?

Cavities are a common dental health problem that most people face at least once in their lives. With a combination of routine dental visits to a dentist in Cleveland Heights, OH, and good at-home oral hygiene, most problems with cavities can be eliminated. Still, some people seem more prone to getting cavities than others. If you’ve ever wondered why some people always seem to get cavities, you’ll be interested in learning about all the factors involved.

Oral Microbiome

The oral microbiome, a complex ecosystem of bacteria and other microorganisms residing in the mouth, plays a crucial role in oral health, including cavity susceptibility. The oral microbiome consists of diverse microorganisms, with hundreds of species coexisting in the mouth. While most of these microorganisms are harmless or beneficial, some species, such as Streptococcus mutans, are cavity-causing bacteria. Individuals with a less diverse oral microbiome, characterized by an imbalance in microbial populations, may be at a higher risk of cavities.

Acidic Levels

Cavity-causing bacteria, such as S. mutans, metabolize sugars from food and beverages, producing acids as byproducts. These acids lower the mouth’s pH level, creating an acidic environment that erodes tooth enamel and promotes cavity formation.

Composition of Saliva

Saliva plays a crucial role in maintaining oral health by buffering acids, washing away food particles, and remineralizing tooth enamel. Its composition, including its pH level, flow rate, and antimicrobial properties, can influence cavity susceptibility. Factors such as dry mouth or altered saliva composition may compromise its protective functions, increasing the risk of cavities.

Diet

Dietary habits can influence the composition of the oral microbiome and cavity formation. Consuming a diet high in sugars and carbohydrates fuels cavity-causing bacteria, increasing acid production and enamel erosion. On the other hand, a balanced diet rich in fruits, vegetables, and dairy products can support a healthy oral microbiome and reduce cavity susceptibility.

As you can see, many factors are involved in the formation of cavities. The best way to ensure that cavities don’t destroy your teeth is to visit your dentist often for dental exams in Cleveland Heights, OH. Contact us today to book your next dental appointment.
