Toothbrush Care

Toothbrush care, cleaning and storage tips.

Bacteria and Toothbrushes

Do you have a family member who leaves their toothbrush everywhere? Have you found it on the kitchen counter, coffee table, dresser, desk or in the car? This is not ideal toothbrush care since the cleanliness and storage are questionable.

It is impossible to keep a toothbrush sterile since germs are everywhere. However, it is good practice to always keep toothbrushes as far away from the toilet as possible. This is important because when the toilet is flushed, a cloud of microscopic particles sprays into the air. The particles can include E. coli bacteria that can spread from the toilet to your toothbrush. The bacteria increase your risk of getting ill with fever, diarrhea, infection, vomiting and stomach pain. This risk can be greatly reduced by closing the toilet lid before flushing.

How to Store Toothbrushes

Do not use a medicine cabinet to store toothbrushes. The cabinet reduces airflow and is a dark and humid environment that promotes microbial growth. To safely store toothbrushes:

• Use holders that store them in an upright position.
• Keep them as far away from the toilet and sink as possible.
• Store them where there is sufficient airflow to ensure proper drying.
• To avoid spreading bacteria across toothbrushes, do not let the bristles from different toothbrush heads touch.

Simple Toothbrush Rules:

• To avoid cross-contamination, do not share your toothbrush with others.
• Rinse your toothbrush with tap water after each use.
• Store your toothbrush in an upright position and allow it to air dry.
• Clean your toothbrush holder regularly.
• Don't routinely cover or store toothbrushes in closed containers.

Replace your toothbrush every 3-4 months or when the bristles flare. Children's toothbrushes may need to be replaced more frequently.

There is no evidence that soaking a toothbrush in antibacterial mouthwash or using a sanitizer has any effect. Using a dishwasher or other appliance to clean a toothbrush can damage the brush and its bristles.
