This is Why You Can’t Blame Genetics for Bad Teeth

For years, people have attributed their mouth problems to family genes. But new research shows that you can’t blame genetics for bad teeth. In reality, it’s caused by the foods you eat and your daily oral care habits.

Inherited microbes, not genes

Researchers at the J. Craig Venter Institute in Maryland studied the oral health of twins, ages 5 to 11. They discovered that people inherit some mouth microbes from their parents. But, the studies showed, these microbes do not cause cavities. In fact, the number of hereditary bacteria in the mouth decreases with age.

Oral bacteria

The mouth contains over 20 billion bacteria that reform every five hours. Most of these are healthy microbes that occur naturally and help breakdown foods and protect your teeth and oral tissues. However, some of the bacteria are harmful and can cause tooth decay and gum disease. The two most common bad bacteria are:

  • Streptococcus mutants – This bacteria feeds on sugars and starches found in food particles that get caught in the teeth and gums. If not removed by daily brushing and flossing, they can cause tooth decay.
  • Porphyromonas gingivalis – Normally this bacteria microbe is not found in a healthy mouth. If it develops, it’s a sign of periodontitis, a serious bacterial infection that attacks the tissues and bones that support the teeth. If left untreated, the bacteria can cause tooth loss.

Oral care tips

For a lifetime of use, take good care of your teeth and gums by following these tips:

  • Schedule professional cleanings, as directed by your dentist.
  • Eat nutritious foods including a good mix of vegetables, fruits, dairy and lean meats.
  • Limit sugary snacks, desserts and beverages.
  • Brush teeth twice daily, after breakfast and at bedtime, for two minutes each time. Don’t forget to carefully brush your tongue to remove bacteria that can collect on the surface.
  • Floss teeth once a day.
  • Rinse mouth with a non-alcoholic mouth rinse to remove food particles and kill harmful bacteria.
