I've been again having some bite and gum problems in at the upper right rear of my mouth. My regular dentist suggested extraction of the rear-most and/or a consult with a periodontist so I'm off to that this afternoon. If it is an extraction that will be my first other than Wisdom teeth. Since it is the rear-most it doesn't need to be replaced. I got to take the Xray with me so I of course scanned it.
