The toothbrush is your number one oral hygiene accessory. Toothbrushes help keep your teeth and mouth clean, but how long should you a keep a toothbrush?
It is recommended that you switch out that old toothbrush for a fresh new one every 3 to 4 months. Replacing your toothbrush is essential since it is constantly being exposed to germs and bacteria. If you notice the bristles of your toothbrush have become worn that's a clear sign you need a new toothbrush.
People who wear braces should change their toothbrushes more frequently because braces break down and fracture bristles which makes the toothbrush lose its effectiveness.
It's helpful to keep a pack of toothbrushes available in the house at all times for easy replacement.
3 Reasons to Change Out Your Old Toothbrush:
1. Bacteria - Your toothbrush is a tool for removing bacteria from your teeth…but it doesn’t actually kill bacteria. Some of the bacteria from your teeth stay on your toothbrush after you are done brushing. Now, this isn’t a problem initially, but imagine three to four months of bacteria build up on your toothbrush. That old bacteria ridden toothbrush is in your mouth at least twice a day…yuck.
2. Bristles - Like any tool, a toothbrush wears down. Worn bristles are tough on your enamel and can wear it away over time. Not only that…an old, worn toothbrush can be up to 95 percent less effective at removing plaque.
3. Illness - Always change your toothbrush after you’ve been sick, even if it’s not “technically” time to switch out your toothbrush.
