If you are using an old toothbrush, then it is not removing all of the food debris from your teeth. In addition, an old toothbrush will contain a lot of bacteria that can lead to gingivitis or halitosis. Your orthodontist will tell you to replace your toothbrush every three months, but if a toothbrush’s bristles look frayed, then throw it away before buying a new one. The best way to remember to replace a toothbrush is by marking a date on a calendar, and it is a good plan to buy new toothbrushes for everyone in your family at the same time.
