Just as a dentist will recommend changing toothbrushes every three months or thereabouts the same applies to the head of an electronic toothbrush. After this period of time the bristles have become worn and not as effective in cleaning the teeth and gums. Also, bacteria will build up and this can lead to infections and other dental problems. However, the toothbrush head should also be changed if you have received treatment for:
– Gum disease
– Tooth loss
This is because the bacteria responsible for these conditions “may still be present on your toothbrush” and re-infection is a real possibility.
