@a-lone-raven requested some reference photos for raccoon teeth! Hope these will help! My apologies for taking so long to post these!
A little tidbit on telling the difference between raccoon upper and lower incisors (and most other mammals with upper and lower incisors) is to remember that the upper incisors have shorter, more curved roots and that the lower incisors have longer, straighter roots.
