Ask Dr. Stanfield: When should I change my toothbrush?
If you can’t remember the last time you replaced your toothbrush… replace your toothbrush today! As a rule of thumb, when the bristles on your brush become slightly splayed, it should be changed and replaced. A worn-out brush is ineffective at cleaning your teeth and gums.
Also remember, your toothbrush should be used to clean your teeth, not your floors or your jewelry!
What is the best toothbrush?
The best toothbrush is one with soft (not medium or firm) bristles and a comfortable handle. Buy a name brand, because overall quality of the brush and its components will be guaranteed. Some good brands I like are Butler, Crest, Oral-B, and GUM.
I think electric toothbrushes are a good option, particularly for older folks who have reduced manual dexterity and anyone with braces. The better electric brushes are the ones with name brands and, unfortunately, a higher price tag. I personally prefer the Phillips Sonicare brush.
