Can “Bad Teeth” Run in the Family?

Parents are usually the ones responsible for teaching their young children the importance of brushing their teeth. However, while parents can help kids develop healthy oral hygiene habits, there is one thing they cannot control: genetics. Did you know that bad teeth can run in the family? Just like your genes determine the color of your hair and eyes, they also play a role in your oral health. Here are some common dental problems that are connected to genes.  

Tooth Decay

Do you brush your teeth diligently but still get cavities? Your genes may be to blame. Researchers from the University of Pittsburgh School of Dental Medicine recently found that tooth decay can be influenced by variations in certain germ-fighting genes.

Gum Disease

Research indicates that up to 30% of the population may be genetically predisposed to periodontal disease (also known as gum disease). Untreated gum disease can lead to tooth and bone loss and has even been linked to serious diseases like Alzheimer’s. Fortunately, early detection and treatment can usually reverse gum disease.

Oral Cancer

More than 50,000 Americans are diagnosed with some form of oral cancer each year. Lifestyle choices such as tobacco use and heavy alcohol consumption are major risk factors for this type of cancer. However, genetics also play a minor role, as having a family history of oral cancer is also considered a risk factor. Statistics also show that oral cancer is twice as common in men as in women.  

Crooked Teeth

Did you wear braces in middle school or high school? If so, you should not be surprised if your children need orthodontic treatment when they reach the right age group. Genetics play a major role in the size of a person’s jaw and whether they have enough space in their mouth for all their teeth.  

Tooth Color

Tooth color is influenced by both genes and lifestyle choices. The density of the tissues that make up your teeth determines their natural color. Some families are lucky and naturally have thicker and whiter enamel. However, even naturally bright teeth can stain over time, especially if you smoke tobacco or frequently drink dark beverages like coffee or red wine.

How to Preserve a Healthy Smile

Although your genes can influence your oral health, they do not have to define it. People at risk of heart disease can make healthy choices to improve their cardiovascular health. Similarly, you can take steps to preserve a healthy smile, such as:

• Brush twice a day for two minutes at a time
• Floss daily
• Avoid eating sugary snacks
• Quit smoking and avoid heavy alcohol consumption
• Visit a dentist every six months for an exam and professional cleaning

Finally, be sure to share your medical history with your dentist. Doing so will help them better understand your risk of tooth decay and other oral health issues and develop personalized prevention and treatment plans.
