How Genetics Affect Children’s Dental Health

Every person has a hereditary genetic code, specific DNA sequences passed on from parents to their children. Genetics affects every aspect of our being, from the color of our eyes and hair to our ability (or inability) to roll our tongues. Genetics can make us more or less susceptible to developing certain health problems, and they can have a big impact on our oral health. 

Is There a Connection Between Genetics and Dental Health?

Yes, genetics and dental health are connected. A person's genetics has an effect on oral health in a variety of ways, including:

  • The size and shape of the teeth
  • Tooth alignment, spacing, and crowding
  • Occlusion (bite alignment)
  • Enamel strength
  • Jawbone growth and function
  • General myofascial anatomy
  • Saliva composition
  • Oral microbiome composition
  • Lip and tongue tie

Genetics also plays a role in a person's risk for developing certain oral health problems, such as:

  • Tooth decay and cavities
  • Periodontal (gum) disease
  • Orthodontic problems
    • Malocclusion (abnormal bite alignment)
    • Irregularly timed tooth eruption
    • Crooked or crowded teeth
    • Irregularly gapped teeth
    • Abnormal jaw size
  • Congenital or hereditary dental conditions
    • Amelogenesis imperfecta (abnormal tooth enamel development)
    • Dentinogenesis imperfecta (irregular dentin formation
    • Condylar resorption (jawbone degeneration)

What Parents Should Know About Hereditary Dental Conditions

Routine dental examinations, professional teeth cleanings, and preventative dental care (such as fluoride applications, dental sealants, and interceptive orthodontics) can help ensure the early detection and diagnosis of any potential oral health problems that your child might encounter.

It can also be helpful for parents to talk with our dentists about their own oral health history. Any issues that a child's parents have encountered could potentially increase the risk of a child experiencing the same or similar issues. 

Inherited Behaviors: Environment, Lifestyle, Nutrition, and Healthy Habits Are Important, Too

While genetics creates a baseline of oral health and predispositions to developing certain oral health issues, they are not the only factor in determining your child's oral health. Inherited behaviors such as oral hygiene habits, nutritional habits, lifestyle habits, and a child's environment can also significantly impact a child's oral health. 

As a result, regardless of your child's genetic predisposition for optimal or less-than-optimal oral health, helping them develop healthy habits can curb the effect of their genetic makeup, giving them a better chance at developing a strong foundation of oral health. 

To promote good oral health in your child, we recommend:
  • Teaching positive oral hygiene habits (good brushing and flossing techniques)
  • Feeding a healthy, nutritious, and well-balanced diet
  • Visiting the dentist every six months
  • Talking with children about the importance of good oral health
  • Being a good role model and taking care of your own teeth
Living a healthy lifestyle will promote overall better health, helping to support good oral health, too. By keeping the body and its immune system strong, your child will also enjoy better oral health, stronger teeth, and healthy gums.
