The answer is the same for both a manual toothbrush or if you are replacing the head on an electric brush. It is recommended that toothbrushes be replaced every 3-4 months. For those using an electric toothbrush that frequency can seem a little costly. But the reason for such a short lifespan of your toothbrush is simple: our brushes can harbor more germs, bacteria, and fungus than we care to know about. Reintroducing these unwanted germs repeatedly into your mouth is not the healthiest thing we can be doing for our bodies.
It is also recommended to replace your toothbrush after recovering from a cold, mouth sore, flu, sore throat, illness, after returning from travels, and after having your teeth cleaned. Your child’s toothbrush should be replaced even more frequently since the bristles tend to wear out faster, making it less effective.
