كيف تنظف فرشاة أسنانك؟

هذا ما يقوله د.ويل:

1. Rinse the brush thoroughly after use and let it dry in an upright position.
2. If you keep your brush in the same holder as others in your family, make sure the bristles don't touch each other.
3. Don't share toothbrushes.
4. Keep your toothbrush in a location well away from the toilet - flushing can allow bacteria to travel from the bowl to your brush
5. Never store your toothbrush in a closed container - bacteria are more likely to multiply in a warm, humid, closed environment.
6. Replace your toothbrush every three to four months, or sooner if you notice that it looks worn (look for bristles that are splayed or bent out of shape).
