Taking Care of Your Most Important Brush
Have you ever looked at your toothbrush and forgotten how old it was? Could it possibly be older than 3 months? If the answer to that question is “Yes”, you need to go to the store and buy a new brush as soon as possible and throw away your old brush.
Toothbrushes need to be replaced every three months because the bristles deteriorate and are not effective in cleaning your teeth. When the bristles start to flare outwards and appear frayed, it is time to go shopping for a new brush. To be effective in cleaning your teeth, the bristles must be standing straight up.
If you have been sick recently with a cold or the flu or a herpetic infection, replace your toothbrush because bacteria and germs that cause these illnesses can grow on your brush and cause reinfection with the illness. Bacteria can grow on food particles left on your toothbrush when it is not rinsed thoroughly. When you rinse your brush, always check to see that all food particles are gone. If they are not gone, rinse again.
Using the dishwasher or microwave to sanitize your toothbrush will only damage it. Do not use these techniques for home care.
After rinsing your toothbrush, place it in an upright position to dry. Placing it in a travel case or drawer provides an environment for bacterial growth. Air drying is best to inhibit bacterial growth. The circulation of air helps prevent an environment for bacterial growth.
For disease prevention, do not share your toothbrush with anyone else, and do not allow brush heads to touch in the toothbrush holder. This provides an environment for cross-contamination.
REMEMBER: When in doubt, throw it out!
