No: Have the calculus (tarter) professionally removed...it causes gum/bone recession. Have your Dentist teach you how to keep it from reforming.

DDS evaluation: Get a definitive diagnosis from your dentist. You mention that the dentist stated that calculus is present, after a through prophy, your issues should be remedied. If the dentist feels that you need to follow through with scaling and root planing or an evaluation with a periodontist- do it.
