Does this look a bit too familiar?
Too often people believe that this is what should signal the replacement of your toothbrush or toothbrush head. Unfortunately, if you are seeing this, you are way overdue!

Toothbrushes should be replaced every three months to ensure you are getting the most benefit you can from your twice daily brushing habits. To help keep you on track, try writing the date you pulled out the toothbrush on the handle.
