Without proper toothbrush care, the plaque and debris your toothbrush has removed from your teeth will continue to sit on your toothbrush. Toothbrushes can become contaminated by several different things: bacteria, saliva, oral debris, blood, and toothpaste. Because of this we recommend that you rinse your toothbrush thoroughly with water after each use, shake off excess water, allow it to air dry and store in an upright position. While this won’t eliminate all bacteria, it will help remove some of it.
Other steps for toothbrush care include:
- Replace your toothbrush every 3-4 months (or sooner if you notice that the bristles are splayed or worn)
- Don’t store in a closed container. Being in a moist environment can increase bacteria growth
- Do not share your toothbrush with others, and if you store your toothbrush in the same container with someone else, do not allow them to touch as this can spread bacteria from one toothbrush to the other.
