How often should you change your toothbrush, and which one should you use?

Tooth brushes

It is essential to replace your toothbrush every 2–3 months, or even sooner if the bristles become frayed, bent, or worn out. A worn toothbrush is far less effective at removing plaque, bacteria, and food debris, which can increase the risk of tooth decay and gum disease. Regularly changing your toothbrush ensures you are always cleaning your teeth with a tool that works effectively and keeps your oral hygiene routine at its best.

Whether you are choosing a manual toothbrush or an electric toothbrush, the key is to ensure the head size, bristle type, and replacement schedule match your individual needs. Following these guidelines will help you maintain healthy teeth and gums, keep your breath fresh, and support long-term oral health.

Best type of toothbrush for adults

For adults, the best choice is usually a small or medium-sized toothbrush with soft or medium, multi-angled, round-ended nylon bristles.

These bristles are designed to be gentle on the gums while still reaching between teeth and along the gumline to remove plaque. A smaller brush head is recommended because it makes it easier to reach all areas of the mouth, including the back teeth, which are often missed with larger brushes.

Best type of toothbrush for children

Children need to use smaller toothbrushes that comfortably fit their mouths

The bristles should be the same type – soft or medium, round-ended nylon – to protect their developing teeth and sensitive gums. Choosing a toothbrush that is the right size and shape for your child helps encourage good brushing habits from an early age.
