I just had one root-canal (#18 molar-left lower jaw) extracted a couple of days ago and it helped me regain the full use of the left side of my body. Since the adjoining tooth of the pulled #18 is also missing, I really don't have enough lowar molars for chewing (and by the way, the root-canaled molar on my right side is now in queue for extraction). What sort of materials do you recommend in place of the missing molars?
