dental cleaning at a dentist's office---who does it?

Hi,

Usually I get my teeth cleaned in the US, but won't be able to go this year, and thus, will miss my usual 6 month cleaning appointment.

Never been to a dentist in Belgium and was curious---if I just want to have a dental cleaning done, who does it, the dentists, or is there another person doing this task?

Also, is it acceptable to just have a dental cleaning and not the dental checkup?

I just want to have the dental cleanup since I already had my dental checkup by my dentist in the US earlier this year.

thanks!
