A mini dose of sedative, and a few power tools later, Tess doesn't need dental work for another year (yippee!) I had my vet come out and do it (as the gal I normally use lives by the folks and the scheduling just wasn't working out)
Dr. K mentioned that Tess didn't have any "bit seats" so she went ahead and put some very non-aggressive ones in.
A "bit seat" is a rounding of the edges on the first set of back molars:
The points can catch the inner cheek between the bit and the teeth - pinching it and causing pain.
Dr. K said I will feel a total difference in how Tesla feels in the contact.... I'll keep you posted :)
