When the dentist told Tina Valek that her gums were eroding near her back teeth, the news came as a surprise to the 32-year-old. After a lifetime of perfect dental checkups without a single cavity, Tina thought she was doing all the right things. So what was the problem? She was overbrushing.

“Vigorous brushing can cause gums to recede and over time erode tooth structure, leading to sensitive teeth and exposure of the root area,” said Jed Jacobson, D.D.S., M.S., M.P.H., vice president of Professional Services and dental director at Delta Dental of Michigan, Ohio and Indiana. “Severely receded gums may require gum grafts or other procedures to repair damage caused by long-term overbrushing. A proper brushing technique will help keep teeth and gums healthy.”

• Brush at least twice daily, especially after meals
• Use gentle circular movements at a 45 degree angle to help brush away plaque
• Floss daily
• Visit the dentist regularly

It is also important to use a soft-bristled toothbrush and replace it every three months to avoid bacteria buildup on the bristles. Beyond that, it’s a matter of personal preference whether you choose a toothbrush with an angled head, battery-powered, or a toothbrush with a special handle, as long as you’re able to reach all of the surfaces of the teeth.

“If you begin to experience any pain or tooth sensitivity, talk with your dentist or hygienist,” said Dr. Jacobson. “A dental professional can advise you on the proper brushing technique and let you know if you’re applying the right amount of pressure.”
