When do we need to throw out our toothbrushes?

Change yourtoothbrush every three to four months, or when the bristles look frayed andgross. Partially because fresh bristles clean best, and also because you wantto avoid putting germs back into your mouth with an old tool. Soft bristles arepreferred – they are most gentle. The size and shape really depend on yourmouth. Since your husband has a larger mouth, he’ll probably need a biggerbrush to reach to the farthest depths, but it really comes down to personalcomfort. If you want handles to match your bathroom, that’s fine too. The mostimportant thing is to brush your teeth twice a day; not so much what kind orbrand of brush you use.
