As we age, many of us become more conscious of our oral health. We brush twice a day and floss daily as well as visit the dentist regularly. Yet, some still find themselves susceptible to cavities and other oral health issues despite these efforts. Is this due to genetic inheritance? Could soft enamel be an actual genetic trait?
To answer these questions, let's first take a closer look at what causes cavities. Cavities are caused by tooth decay, where bacteria in our mouths produce acids which wear away at our enamel, an important protective layer on each of our teeth that serves to shield us against cavities. Therefore, those with thinner or weaker enamel could be more prone to cavities than others.
But is soft enamel genetic? While no single gene has been linked with soft enamel development, studies have indicated that genetics could play a significant role. One Journal of Dental Research study demonstrated this linkage: up to 50% of variation in enamel thickness can be attributed to genetic factors alone! If either one of your parents has soft enamel, there's a chance you could inherit their trait as well.
Still, are cavities themselves genetic? Although no single gene has been identified as being responsible, studies have demonstrated how genetics may contribute to our susceptibility for cavities. One such research paper published in Caries Research revealed a substantial genetic component to caries development, accounting for up to 60% of variations in caries experience.
Genetics play an important part in our susceptibility to cavities, but diet, oral hygiene practices, and environmental influences also have an effect. If you eat too many sugary or acidic foods and beverages regularly, however, this could increase your likelihood of cavities regardless of genetic predisposition.
So, how can you protect your oral health if genetics could be an underlying factor in the susceptibility to cavities? The key is maintaining good oral hygiene habits; brush twice daily, floss daily, and visit the dentist for regular checkups and cleanings. You should also limit sugary and acidic food and beverages while considering using fluoride mouthwash or toothpaste to strengthen enamel.
Additionally, certain dental treatments can also help protect soft enamel or cavity-prone teeth. Dental sealants provide a thin, protective coating that can be applied directly onto the surface of teeth to help prevent decay. Fluoride treatments and varnishes can strengthen enamel against future decay as well.
Genetics certainly play a part in our susceptibility to cavities and other oral health problems; though, diet, oral hygiene habits, and environmental influences can have an effect on oral health too. If you're concerned about your oral health, be sure to maintain good hygiene practices and speak to a dentist regarding any concerns that arise.
