Do Cavities Run in Your Family? 5 Things You Should Know

Everybody’s mouth is different. In fact, if you were to get imprints of your dentition, it would be as unique as your fingerprints. But have you noticed that almost every member in some families has cavities despite good oral hygiene? Why is this? Do cavities run through families? Pearl Dental Care in Hamden, Connecticut, is here to help families understand and manage their unique risks. 

Do genetics contribute to cavities?

Yes! Genetics can play a significant role in your risk of developing dental cavities. The shape of your teeth, saliva production, and oral microbiome can raise the risk of tooth decay. 

Here’s a closer look: 

1. Enamel strength: Enamel is your first line of defense against cavities. Some people have naturally thicker, more resistant enamel. Others have thinner or softer enamel that may make teeth more vulnerable to decay.
2. Enamel shape: The shape of your teeth can affect how easy they are to brush and floss. If your teeth have deep pits and fissures, they’ll likely trap food debris and plaque. Over time, these two factors promote tooth decay. 
3. Saliva composition: Saliva is essential in washing away food debris, neutralizing PH, etc. The amount and quality of saliva you produce can affect how well you fight harmful bacteria. Unfortunately, some people inherit dry mouth syndrome, which increases the risk of decay. 
4. Oral microbiome: This refers to the types of bacteria naturally present in your mouth. Research shows that families share bacteria, especially between parents and children. If you have more cavity-causing bacteria, you can pass them down to your young one through kisses or sharing utensils or food. While this is environmental and not hereditary, it often shows patterns in families.      
5. Taste preferences: Some people have a stronger inclination toward sweet foods, which can be influenced by genetics. As you know, bacteria break down sugars and produce acid as a byproduct. This acid attacks tooth enamel, gradually eroding its mineral content through demineralization. If these acids happen frequently, the enamel weakens and cavities develop, especially with poor oral hygiene.

Even if your DNA points to a high risk, your choices can make a real difference. Genetics increases your susceptibility, but your everyday choices shape the outcomes. No matter your background, brush and floss your teeth at least twice daily. Limit the consumption of sugary and acidic foods and avoid sharing utensils and toothbrushes. Visit your dentist at least twice annually (or sooner), even if everything seems fine. You can talk to your dentist about dental sealants and fluoride treatment for added protection. This comprehensive care creates a strong defense against cavities, even if genetics say otherwise.
