Are electric toothbrushes better than manual toothbrushes?

Posted April 03, 2012

DEAR DOCTOR K: I’ve been brushing with a manual toothbrush my entire life. But my best friend insists that electric toothbrushes are better. Should I switch?

DEAR READER: What matters most is that you brush your teeth at least twice a day. That’s the way you keep plaque from forming. Plaque is a sticky film that attaches to the surface of your teeth. If it isn’t removed, it can lead to tooth decay and gum disease. Brushing regularly keeps plaque in check.

DEAR DOCTOR K: I always thought chewing gum was bad for my teeth. But then a friend told me it actually helps prevent cavities. Who’s right?

DEAR READER: My mother would have said your friend is wrong. But actually your friend is partly right. The answer depends on the type of gum you’re chewing. If your gum contains sugar, then you’re not doing your teeth any favors. But sugar-free gum can be a good thing.

DEAR DOCTOR K: I’d like to have whiter teeth. But no matter what I try, including whitening toothpaste and other drugstore treatments, I can’t get the brightness I want. Can professional treatments help?

DEAR READER: There are many myths and misconceptions when it comes to our teeth. One of the most common is that all stains and discolorations can be easily whitened or cleaned away. Sometimes they can, but it depends on what’s causing your tooth discoloration. Sometimes even professional procedures can’t make your teeth sparkling white.
