The autumnal equinox happened quietly on Sunday ushering in Fall. As the seasons change, so should your toothbrush.

The American Dental Association strongly suggests replacing your toothbrush every three to four months. With your brain filled with many important details, it might prove a bit difficult to remember when you bought your last toothbrush, which can make it equally difficult to buy a new one in a timely manner. So here is an easy mnemonic device to help you along. Change your toothbrush every time the seasons change and then you will be replacing the old one every three months, just like the ADA suggests.

Simple right?
