Studies have demonstrated that those who have a family history of poor dental health are likely to experience oral health issues themselves. While not all aspects of oral health are inherited, this research has demonstrated that it plays a distinct role. Our family genetics can influence how our teeth develop, how they fit together, and what developmental concerns we may experience. Even the resistance of enamel to bacteria has been shown to have a genetic component.
The Role Of Genetics In Oral Health
A significant part of your oral health is directly affected by your genetics. The mouth and bone structure composition is directly linked to your parental heritage. It’s not uncommon to see a family line of misaligned teeth, with each generation sharing similar concerns to those before. Some commonly inherited oral health concerns are:
- Teeth that are crooked or overcrowded
- Jawbone size and shape
- Issues with an improper bite
- Temporomandibular Joint Disorder (TMD) concerns.
One area that remains largely unaffected by genetic heritage is poor oral hygiene habits. Even with a familial history of poor oral health, maintaining good oral hygiene can be an effective deterrent. Overcrowded or misaligned teeth can often create a situation where teeth are difficult to clean. This means that bacteria will be able to effectively hide from your toothbrush. You can give yourself a leg up by checking to see if your relatives experienced the following concerns:
- Periodontal Disease (Gum Disease) is common even in families with good dental composition. However, there is evidence that nearly 30% of the American population may have a genetic tendency to develop this condition. Common symptoms of this condition include inflamed and sensitive gums that bleed when brushed or flossed. Treatment and diagnosis can help prevent the advance of these conditions when done early. Speak to your dentist if your family has a history of this condition.
- Tooth Decay – While most dental decay is due to poor oral hygiene habits, there can be a genetic component. The appearance of certain gene variations can make it more likely for you to develop cavities in your permanent teeth. This can be due to weakened enamel or impaired response to bacterial attacks.
- Weak Teeth – Teeth can become weak when deprived of necessary nutrients due to a deficient diet. Genetic elements can have a role to play as well. One good step towards protecting your teeth, in this case, is fluoride treatments. Let your dentist know if there’s a family history of this condition.
These are just three oral health conditions that can be tied to genetic heritage. Each of them represents an oral health concern that can be addressed with the help of your dentist.
Family History For Oral health
Communicating with your family about your history of oral health can be important. It can provide valuable warning about the kinds of conditions you may face. Consider speaking to your family about their oral health history and sharing it with your dental health provider.
