I am 20 years old with no health insurance(dental).i want to know what exactly I should do and how much will it cost? I have never been to the dentist. I do not know how long these stains were on my teeth( I noticed it recently, when I seen this black tartar growing between mandibular teeth. Do I need a scaling and polishing done by a dentist or do I need scaling and root planing.the stains are only on the lower 6 front teeth, but they are brownish black. Please tell me what I have to do.i can send you picture of my teeth.
