Summary

The goal of this randomized clinical trial is to investigate two different types of toothbrush bristles.

The main questions it aims to answer are the effects of two different bristle types on:

* how much plaque is on the teeth
* how deep the space is between gums and teeth
* how much gum and bone are attached to the teeth
* whether the gums bleed when checked
* if the gums get scratched or irritated

Researchers will compare toothbrushes with tapered bristles to those with regular round bristles.

Participants will be randomly assigned toothbrush A or B to use at home during the study.
