The back of my bottom set of teeth feel rough and dirty. should i be worried?

Yes: The back of lower front teeth is a common area to build up tartar. This tartar is old plaque that becomes hard or calcified from the minerals in saliva. It feels rough to your tongue. This will cause gum inflammation that make them bleed and sore. Will lead to more serious disease and infections. Gum disease is common in adults but can be controlled. See your dentist.

Concerned: A roughness on your teeth is an indication that calculus is present. Calculus is hardened plaque and needs to be removed professionally. The plaque is full of bacteria that release acid, causing irritation of your gums, bone loss, loss of teeth, and halitosis. Have yourself examined and treated.

Yes: This is tartar from old plaque which has become hard or calcified. The bacteria from this can cause gum problems and problems for your teeth. I suggest getting a professional cleaning as soon as possible from a dental office.

How long: how long has it been since your last Dental Examination and professional cleaning? Tarter on the backs of your teeth can cause gum and bone loss. Please do not put this off, call your Dentist NOW.
