How does the dentist should clean dentures?

Ultrasonically: Dentists will place the denture in a solution called "tartar and stain remover" and place the container in an ultrasonic bath. The shock waves within the solution speed up the action of the solution to dissolve hardened deposits and dislodge stain from the denture. The use of a "high shine" material applied to the denture can restore a high lustre to the denture surface.

Ultrasonic, brush, : I clean dentures in an ultrasonic bath first and then clean them the same way you do at home...With a brush and non-abrasive cleaning agent. Clean your dentures thoroughly every day with a non-abrasive cleaner such as liquid soap and rinse thoroughly.

Ultrasonics: A liquid bath of chemicals with ultrasonic waves thru the liquid.

Special chemicals.: The dentist will have his staff clean the denture with special instruments and solutions to remove stains, plaque, or any buildiups present. They will then be polished to a high shine. Keep smiling !
