Not changing our toothbrush regularly :
How often do you change your toothbrush? Most of us wait until most of the bristles have either fallen off, or are in such bad shape that we”d be embarrassed to pull out our brush in public. However, since not many of us need to pull out our brush in public, we carry on with our frayed one until we lose it. Replace your toothbrush often. Damaged bristles can harm the enamel, and don”t massage your gums well. If you find brushing your teeth a pain like I do, but know you must do it, you might as well be doing it right. Imagine going through the annoyance of brushing your teeth twice a day only to find out that you”re damaging your enamel every time you clean your teeth. Also, use a brush with soft bristles unless your dentist has advised otherwise.
