hi
In terms of the views of dentistry,
1. is there any difference between a normal cheap brush and an electric brush? would an electric brush work much better?
2. I've heard about something like 'sonic' brush recently, it looks like they are different from generic electric brush, in what way are they better?
3. what is usually the main difference between a high-end electric/sonic brush and a low/middle-end electric/sonic brush??
Thank you so much.
