Dental implant surgery is generally safe, with published success rates above 95% over 5 to 10 years, but it carries real risks including infection, nerve injury, sinus complications for upper-jaw implants, and implant failure to integrate with bone.
Key takeaways
- —Infection at the surgical site is the most common complication and is usually treatable if caught early.
- —Nerve injury, while uncommon, is a serious risk specific to lower-jaw implants placed near the inferior alveolar nerve.
- —Upper-jaw implants carry a distinct risk of sinus perforation if bone height is insufficient and not addressed beforehand.
- —A thorough pre-surgical CBCT scan is one of the most effective ways providers reduce these risks before they happen.
The risks worth understanding in advance
Beyond general surgical risks like infection and bleeding, implant-specific risks include peri-implantitis (a gum infection around the implant that can develop months or years later), nerve damage causing numbness or tingling in the lip or chin, and sinus membrane perforation for upper posterior implants placed near the sinus floor.
How these risks are typically managed
Pre-surgical 3D imaging lets providers map nerve location and sinus position precisely before drilling, which is the primary reason these complications have become less common as CBCT imaging has become standard. Antibiotics are sometimes prescribed prophylactically for higher-risk cases, and meticulous oral hygiene during healing reduces infection risk substantially.
Material-specific considerations
Failure rates between titanium and zirconia implants are broadly comparable in published studies, though zirconia's greater brittleness means fracture under high bite force is a distinct (if uncommon) failure mode that doesn't apply the same way to titanium, which tends to bend rather than crack under stress.

Frequently asked questions
What are the chances my implant will fail?+
Published long-term success rates for both titanium and zirconia implants generally range from 90 to 97% over 10 years, varying by bone site, patient health, and provider experience.
Is nerve damage from implant surgery permanent?+
Many cases of nerve irritation from implant placement are temporary and resolve over weeks to months. Permanent nerve injury is uncommon but possible, which is why precise pre-surgical imaging near the lower jaw nerve canal matters.
