I like to use Howard Leight MAX 🙂
Can you still hear patients/people talking while drilling noises are drowned out?
I am definitely interested in a product that would block out most of the drill noise, yet still let you be able to verbally communicate with people.
Earplugs are the obvious choice, but due to infection control it's not always the best choice and you will definitely go through them FAST everyday which is why I think most dentists don't use them.
