A toothbrush is a tool designed to clean the teeth and gums.

It is usually made up of nylon bristles on a plastic handle.

It is recommended to change the toothbrush every 3 months to maintain good oral hygiene.

Toothbrushes come in different sizes and hardness, depending on each person's needs.

Some toothbrushes also feature advanced technology such as angled bristles or interchangeable heads.

It is important to brush your teeth at least twice a day to prevent plaque buildup and oral diseases.
