Dental implants are considered a safe, well-established procedure with decades of clinical use and published success rates generally above 95%. As with any surgical procedure, individual risk depends on bone health, overall medical history, and the skill of the provider.
Key takeaways
- —Both titanium and zirconia implant materials are classified as biocompatible and are used in millions of procedures annually worldwide.
- —The most common complications — infection and peri-implantitis — are manageable and often preventable with good aftercare.
- —Serious complications like nerve injury or sinus perforation are uncommon, particularly with modern 3D imaging and planning.
- —Safety is also a function of provider experience — ask directly about a provider's placement volume and complication history.
What 'safe' means in this context
No surgical procedure is risk-free, and implants are no exception — but the relevant comparison is to the alternatives: leaving a gap, a removable denture, or a bridge that requires grinding down adjacent healthy teeth. Each of those carries its own long-term risks to oral health, which is part of why implants have become a standard recommendation for many patients.
Material safety specifically
Titanium has an extensive safety record spanning over 50 years of orthopedic and dental use. Zirconia, used in dental and joint replacement applications, is also well-studied for biocompatibility, though its specific use as a dental implant post has a shorter track record simply because it's a newer application of the material.
What actually drives outcomes
Across the research, patient factors (smoking, diabetes control, oral hygiene) and provider factors (planning, technique, experience) tend to influence implant safety and success more than the choice between well-established materials does.

Frequently asked questions
Are there long-term health concerns with having metal implants in your mouth?+
Titanium implants have not been shown in large studies to cause systemic health problems for the general population; true titanium allergy is considered uncommon. Patients with a known or suspected metal sensitivity often discuss zirconia as an alternative with their provider.
Is implant surgery riskier for older adults?+
Age itself isn't the primary risk factor — overall health and bone quality are. Many older adults are good candidates, though providers will assess medications and any conditions that affect healing.
