- Ionic toothbrushes: These brushes are designed to release positively charged ions that change the surface charge of a tooth.
- Orthodontic toothbrushes: They are designed especially for patients with orthodontic appliances. The bristles in the center of the brush are shorter than those present at the periphery allowing it to pass over the appliance without causing abrasion of the teeth.
