How often should you replace your toothbrush? It’s a good question. We all brush our teeth on a daily basis. Like a good pair of jeans, it seems the more we use a toothbrush, the more comfortable it gets. But the dentist at Decatur Smiles in Decatur AL reminds you, that’s not a good thing when it comes to brushing your teeth.
The angle of the bristles on your toothbrush are an important part of cleaning. Straight bristles scrub your teeth and flex your gums. A light circular motion is enough to clean your teeth without causing damage.
Flat or frayed bristles are less capable, and can even cause you to work harder. Pressing harder on your teeth can cause damage.
So, back to the original question: how often should you replace your toothbrush?
Anyone who has worried about changing the oil in their car has learned this basic rule of thumb; change your oil every three months. It’s the same with your toothbrush.
Most dental professionals recommend a new toothbrush every three months. The American Dental Association suggests replacing your toothbrush “every three to four months.”
Bacteria can also built up in the small gaps of your toothbrush and may contribute to decay and bad breath. Make sure you keep your toothbrush in a sanitary location. Allow for good drying to help extend its life.
Regardless of how long it’s been, if the bristles on your toothbrush look like they’re trying to get away from each other, it’s time.
