3. Don’t Overdo It

Brushing more than three times a day might not be ideal, Sesemann says. That's because too much brushing can wear down tooth enamel and damage your gums.

Also, “don’t bear down too hard,” he says. “Use a lighter touch.”

“With electric brushes, you let the bristles do the work and just guide the toothbrush,” Price says.

Be gentle. It doesn’t take a lot of force to remove plaque, he says.

4. Perfect Your Technique

Are you brushing correctly? Wide, side-to-side strokes can cause scrapes along your gum line, Sesemann says.  Hold your brush at a 45-degree angle to your gums, and make an up-and-down motion. Use short strokes.

Brush outer and inner tooth surfaces, back molars, and your tongue. “Don’t forget about those hard-to-reach areas,” Sesemann says. If you aren’t thorough, plaque has time to sit in your mouth and cause damage.

5. Switch Things Up

Do you always begin brushing in the same place? Dentists say most of us do.

"Start in a different place so that you don't get lazy," Price says. By the time you get to the last area of your mouth, you may be bored. Stay aware of what you’re doing.

“Keep track of where you are going and where you have been. Make it to all the surfaces,” Sesemann says.  

6. Pick Products Wisely

The kind of toothpaste you use matters, he says. The things that brighten or control tartar can be harsh. “An increase in whitening particles can be harmful and sand away tooth structure.”

Go back to plain old fluoride toothpaste, he says. If you want to lighten your smile, you can always switch between whitening toothpaste and regular.

7. Control Your Sour Tooth

Energy drinks, diet sodas, and sour candies -- even healthy things like apple juice, orange juice, and coffee -- have acid that can soften tooth enamel, Sesemann says.

If you do go for sour goodies, wait half an hour before you brush. That gives your saliva time to restore tooth enamel. “The mechanical action of brushing softened teeth is the perfect recipe for wearing away enamel,” Sesemann says.
