Turned and misaligned teeth, bite problems, tooth decay, and yellowing teeth are among the most common aesthetic and functional dental concerns in the world. While genetics can play a role in your risk of experiencing these issues, most of the risk factors lie in your environment and oral hygiene practices. Read on to learn what common dental problems can run in your family and which ones are within your power to prevent.

Genetics & Oral Development

The answer to whether or not your parents passed on a gene to make you get more cavities or need orthodontic treatment isn’t as black and white as you may think. Just like with medical conditions, there are a number of factors that play a role in whether or not you’re at a higher risk of developing common oral health problems. Because of that, it’s important to maintain a good oral hygiene routine at-home, and to visit your dentist every six months for professional cleanings. In doing this, you can drastically minimize any genetic factors that may put you at-risk for problems like gum disease.

Common Oral Health Problems & Their Risk Factors

Here are some of the most common oral health problems in the nation. Learn which ones are more influenced by genetics, and which ones are more influenced by your environment and habits.

Gum Disease

The Centers for Disease Control and Prevention estimates that 50% of adults in the United States will experience symptoms of gum disease. If gum disease runs in your family, practicing good oral hygiene can help reduce your risk of developing it and even prevent tooth loss.

Tooth Decay

While genetics can play a role in whether or not you’re pre-disposed to dental decay, your oral hygiene routine plays an even larger role. Cavities are one of the most common dental issues in the world. Fortunately, they can be prevented with routine brushing and flossing as well as bi-annual dental cleanings and checkups.

Orthodontic Problems

Orthodontic problems like a narrow palate, crowded teeth, or bite problems are more heavily impacted by your genetics. If you needed braces as a teen, there’s a much higher chance that your child will need braces as well.

Oral Cancer

Oral cancer is a deadly disease, especially if it’s not caught early on in its development. While genetics can play a minor role in your risk of getting this disease, your habits play a much larger role. Smokers are five to 10 times more likely to develop head and neck cancer compared to those who don’t smoke.

There’s Only So Much in Your Control

An unfortunate but true reality of dental and medical problems alike is that you can only control your own actions. If you’re concerned about developing problems like cavities and gum disease, one of the best methods of prevention is maintaining good at-home oral hygiene by brushing twice a day for two minutes, flossing at least once a day, and rinsing your mouth with antimicrobial mouthwash. Visiting your dentist in Los Angeles twice a year for routine checkups and cleanings can also help keep your oral health on the right track.

By doing these small things that are within your control, you can likely beat out genetic influences in your goal of maintaining a healthy and whole smile for the rest of your life.
