Depilation and scaling is a very precise and difficult process for even a dentist or a dental hygienist. Visibility and touch feel good, and it's important to know if there is a plaque under your gums. Also, you risk tearing and damaging your gums with unsterilized instruments at home. Dentists and health workers won't try to do this, so why are you doing this? Leave the work to the professionals, and don't waste it on the kit.
