Some people only replace their toothbrush when their dentist gives them a new one, but replacing it even more often is actually super important if you want to maintain your oral health.
Most dentists recommend changing your toothbrush after three months of use, which is typically when a brush begins to lose its effectiveness. Bristles become progressively weaker after each use, and once they’ve become too worn out, they lose stiffness, bend away from the teeth, and no longer effectively remove plaque, which can lead to gum disease and tooth decay.
When it comes to replacing your toothbrush, time isn’t the only factor. If a toothbrush isn’t properly taken care of (i.e. stored upright, rinsed/dried thoroughly, kept away from other brushes, etc.), fungus and bacteria can develop on the bristles.
How to take care of your brush:
• Wash your hands with soap and warm water before and after brushing or flossing.
• After brushing, rinse your toothbrush with warm water and store it upright to air-dry.
• Don’t cover your toothbrush until it is completely dry in order to avoid bacterial growth.
• Use a toothbrush only when it is completely dry.
• Never share a toothbrush with anyone.
• Make sure that toothbrushes stored near each other don’t touch.
