Should I get upper second molar implant in addition to upper first molar implant? Second premolar is already an implant.

Hello!Without an exam and x-rays it's difficult to determine what the best course of treatment would be for you. If you have a tooth below your second molar an implant would be beneficial for complete and balanced chewing. Good luck!

In general, the more teeth replaced the better, although there are many factors that need to be addressed when deciding on the best solution for you. Age (you're young), the number and health of opposing teeth (the bottom molars), and future prognosis of remaining teeth (it sounds like you have a history of perioontal disease) all come in to play when making these decisions as well as local factors such as is there enough bone in the 1st molar spot for an implant? Affordability? Overall health? ... 
If you re a good candidate and the yopu can make the $ work, I would recommend the 2nd molar position due to your age and also because they can be recommissioned in the future for other applications lime supporting fixed dentures, etc.

Hope this helps

Hi:It’s always best to replace missing 1st and 2nd molars with implants in order to maintain the bite and balanced chewing on both sides.Best,Dr. Maddahi
