How often should I change my toothbrush is a question we wish we got asked more! The reason is, you should probably be changing your toothbrush a lot more often than you probably are. The average toothbrush sits in a bathroom… where all types of airborne molecules of various “bathroom types”float around (ick!)
Now, there are various devices to cover and sanitize one’s toothbrush that work to varying degrees, however the American Dental Association (ADA)still recommends that you replace your toothbrush approximately every three to four months, or sooner if the bristles are frayed.
Besides length of time you have been using your toothbrush, here are a few reasons you should change your toothbrush regularly:
1) A cold or illness: If you had a cold or illness, it is important to replace the toothbrush to avoid re-infection from germs.
2) The toothbrush was used for anything other than brushing your teeth: This seems like common sense, but it happens! If the toothbrush was borrowed, or used for cleaning anything else besides your mouth, do yourself a favor, and invest in a new one!
3) You’ve recently experienced any cold or canker sores: Any mouth infections can spread to other parts of your mouth through your brush. If you’ve had mouth sores, it is time to retire that old toothbrush.
4) You left your toothbrush out: If you left your brush out on the sink when your toilet was repaired or the exterminator sprayed for bugs… you will want a new toothbrush!
5) The bristles begin to bend: Some toothbrushes show wear quickly for various reasons and become less effective over time. If your toothbrush bristles are bending, it is time for a fresh one!
