What Are the Risks and Complications of Dental Implants?

Every medical procedure carries some risk. Here is an honest look at possible complications with dental implants.

Dental implants are very safe and have a success rate over 95%, but complications can occur.

Common complications (usually minor):
Swelling and bruising — normal after surgery, resolves in 1–2 weeks
Pain or discomfort — manageable with over-the-counter pain relievers
Minor bleeding — normal for the first 24–48 hours
Numbness — temporary numbness in the lip, chin, or tongue from nerve irritation; usually resolves

Less common but more serious:
Infection (peri-implantitis) — gum infection around the implant, similar to gum disease. Can be treated if caught early; if severe, may cause implant loss
Implant failure — the implant does not bond with the bone. Occurs in 2–5% of cases. Often due to smoking, poor bone quality, or infection
Nerve damage — rare, can cause persistent numbness or tingling in the lip, chin, or tongue
Sinus problems — upper jaw implants can protrude into the sinus cavity; usually preventable with proper planning
Implant fracture — very rare, but the implant post can break under extreme pressure
