For oral care, replace your toothbrush once a month.

I asked my dentist about when to replace my toothbrush, and he said it is best to replace it once a month. So, I am replacing it according to that schedule as well.

Since I replace my toothbrushes quickly, I buy and use a large pack. I really like that the colors are all different, so there is no overlap with my family.

These days, toothbrush design is important too.
