How often should I change my toothbrush?

Most dentists agree you should change your toothbrush every three months. Studies show that after three months of normal wear and tear, toothbrushes are much less effective at removing plaque from teeth and gums compared to new ones. The bristles break down and loose their effectiveness in getting to all those tricky corners around your teeth. It is also important to change toothbrushes after you’ve had the flu, a mouth infection or a sore throat. That’s because germs can hide in toothbrush bristles and lead to reinfection. Even if you haven’t been sick, fungus and bacteria can develop in the bristles of your toothbrush -another reason to change your toothbrush regularly.

My tooth brush looks like a shaggy dog within a week. Should I get one with harder bristles?

To prevent unnessary wear to your tooth enamel, all dentists recommend a soft bristled brush. Even medium is too hard. And if your tooth bursh looks shaggy in a week, you need to see your dentist to discuss the correct and more efficient brushing technique. Even in 3 months of brushing, your tooth brush should not look shaggy if you are brushing correctly. If you scrub back and forth, which a lot of people incorrectly do, you will flatten the bristles one way and then the other, and miss all the crevaces between teeth. The correct technique involves circular rotation, and brushing right onto then gums. Feel free to bring your tooth brush along to your next check up for your dentist to inspect.
