A toothbrush is a frequently used personal item. The American Dental Association recommends not sharing it, rinsing thoroughly, and letting it dry upright. This is routine hygiene advice, not treatment for a dental condition.

Keep a separate toothbrush for each person; do not share brushes.
After brushing, rinse the bristles thoroughly under running water to remove remaining paste and debris.
Store the toothbrush upright where it can drain and air-dry.
Do not keep a damp toothbrush continuously in an unventilated closed case.
Replace a brush sooner if the bristles become frayed, matted or worn.
As a general rule, replace brushes every three to four months. Do not microwave or dishwasher-sanitize them; high heat can damage the brush.
