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.
