There are a few different groups of people who may want to avoid dental implants, at least according to some experts:
People with certain types of cancer or chemotherapy may want to hold off on getting implants, as these treatments can weaken the bones and make implant surgery more difficult.
Pregnant women may also want to wait until after giving birth to get implants, as their bodies undergo so many changes that it’s hard to predict how the implant will fare.
People with autoimmune disorders like Lupus or rheumatoid arthritis may also be advised against dental implants, as their condition could make it difficult for the implant to heal properly.
