It's always the same. I go to the dentist, I get a nice clean teeth, and like 2 months later there's a line of tartar showing up. 6 month and I need to go back to remove the thing. It's always on the same front lower teeth. Im wondering if I have tartar below the gum and I should get an x-ray to see if I actually have a nasty buildup under the gumline on these teeth, because it's only these same teeth, so if I had it under the gumline the usual advice like oil pulling, baking soda, doesn't really work. Anyone deals with tartar buildup in here?
