Most adults with adequate jawbone density, healthy gums, and no uncontrolled conditions that impair healing are reasonable candidates for dental implants. Smoking, uncontrolled diabetes, and significant bone loss are the most common factors that complicate or delay candidacy.
Key takeaways
- —Adequate bone volume in the jaw is the single biggest factor — and it's assessable with imaging, not guesswork.
- —Smoking measurably increases implant failure risk by impairing blood flow needed for healing.
- —Uncontrolled diabetes, certain autoimmune conditions, and a history of radiation to the jaw can complicate candidacy without ruling it out.
- —Age alone is not a disqualifier — candidacy is about bone and health status, not a birthday.
What providers actually screen for
A candidacy evaluation usually covers three things: bone quantity and density at the implant site (via CBCT or panoramic X-ray), gum health (active periodontal disease needs treatment first), and overall medical history, including medications that affect bone metabolism or healing, such as certain osteoporosis drugs.
When bone loss doesn't disqualify you
Patients are sometimes told years ago that they 'don't have enough bone' for an implant — but bone grafting techniques have advanced enough that many of those patients are candidates today. A graft adds healing time, generally three to six months before the implant itself can be placed, but it expands who can be treated.
Where metal-free options fit into candidacy
Candidacy for zirconia specifically follows similar bone and health requirements as titanium, with one added consideration: some one-piece zirconia systems require more precise initial bone-to-implant contact, since the angle can't be adjusted after placement the way some two-piece titanium systems allow.

Frequently asked questions
Can I get an implant if I smoke?+
Smoking is not an automatic disqualifier, but it does raise the risk of implant failure and slower healing. Many providers ask patients to reduce or pause smoking around the surgical period to improve outcomes.
Is there an age limit for dental implants?+
There's no upper age cutoff as long as the patient is healthy enough for minor oral surgery and has adequate bone; implants are commonly placed in patients well into their 80s and 90s. Implants are generally not placed in patients whose jaw is still growing, typically before the late teens.
