Hi
The bristles on my toothbrush begin to wear away after 1 week of usage twice a day!  What should I do? Should I change my brush every week?

Answer:

This is a clear sign that you are brushing your teeth entirely too hard.  Remember, brushing, when done the right way, is great for your teeth.  However, brushing too hard is actually bad for your teeth.  It prematurely wears away enamel and can eventually cause sensitivity close to the gum line.  Enamel does not regenerate and you may eventually need a restoration (filling) if you continue to brush with great force.  Continue to brush after each meal but just remember that light to medium force is all you need to accurately clean your teeth.  The bristles in your toothbrush should at least last 2-3 months (see our article on when to change your toothbrush).  Any time less than this is an indication that you may brush too hard.  Also, if you happen to use a soft bristles, step it up to medium strength bristles.  These may last a little longer in your situation.

Good Luck!
