Which type of polishing tool should be avoided when treating hypersensitive teeth?

When treating hypersensitive teeth, the use of a heavy polishing device should be avoided because it can generate significant pressure and friction against the tooth surface. This increased pressure could exacerbate any existing sensitivity, causing discomfort to the patient. Hypersensitive teeth are often more vulnerable to irritation and discomfort, so a gentler approach to polishing is essential.

In contrast, a rubber cup with fine paste, a soft cloth disk, and a tapered brush with minimal pressure are considered gentler alternatives. These methods provide a more controlled and less abrasive polishing effect, which is more suitable for patients experiencing sensitivity issues. They help in minimizing discomfort while still effectively cleaning the teeth. Therefore, selecting a polishing method that minimizes force and abrasion is crucial when dealing with hypersensitive teeth.
