{Purchased with my own money} - It is an interdental brush.

3~4 I have been going to the dentist for several months.

I am currently undergoing implant treatment because a few of my teeth are giving me trouble.

Regarding this... while I was getting a scaling, the nurse called an assistant and told her to bring an interdental brush.

They explain it after the scaling is finished.

You have to try brushing your teeth 60% They are saying that because the teeth are not cleaned properly and the spaces between them cannot be reached, plaque forms and causes cavities, so you should use an interdental brush every time you brush your teeth.

I was recommended this and have been using it diligently. ~~
