We caught up with British Dental Association scientific adviser, Professor Damiel Walmsley, who advised on the best ways to keep your toothbrush in good condition.

Do you need to clean your toothbrush?

Yes you should. They will harbour bacteria, other microorganisms, saliva and other bodily contamination. A simple rinse after toothbrushing under the tap will get rid of debris and other material. Then store them upright in the open. Most importantly, don’t share your toothbrush as you may share the bacteria and other germs with your family.

How do you clean your toothbrush?

Rinsing under water and storing them upright should be enough. You can use mouthwash to rinse them and give them a quick soak. However don’t leave your brush in the mouthwash. Milton’s solution which is used to clean babies bottles is an effective cold disinfection procedure.

How often should you replace your toothbrush / toothbrush head?

A rule of thumb to replacing toothbrushes is every 3 to 4 months especially if the bristles start splaying out. It is also good practice as your brush may not be as effective if the bristles start to flay outwards.
