If you’re wearing braces, you might wonder how often you should change your toothbrush. Your dentist has a general rule of replacing your toothbrush every three to four months. However, your particular situation may require you to replace your toothbrush more frequently.
Brushing teeth is your first line of defense against oral health problems. Food particles and plaque can build up on your teeth and cause cavities and bad breath. In addition, harmful bacteria can develop in your mouth, resulting in gum disease and tartar buildup.
The American Dental Association recommends that you replace your toothbrush every three to four months. Using an old or dirty toothbrush can re-introduce bacteria into your mouth, causing an infection.
You should also replace your toothbrush after you’ve been sick or have been to the dentist. It’s important to do this because it prevents you from reinfecting yourself and spreading germs.
A new toothbrush should be replaced when the bristles of the brush begin to appear frayed. This is a common warning sign that you need to buy a new one.
Another common warning sign that you need to change your toothbrush is when the bristles start to look bent. Braces can exacerbate the wear on your bristles, so it’s best to buy a new one as soon as you notice the bristles start to get bent.
In addition to changing your toothbrush, you should floss your teeth at least twice a day. Flossing will remove plaque from areas your toothbrush bristles cannot reach.
