Are You Suitable for Dental Implants? An Honest Assessment

Last updated: July 2026 · 6 minute read

Most adults who've lost teeth can have implants, but "most" isn't "all", and the factors that matter aren't always the ones people expect. This is how implant dentists actually assess a patient.

The big one: bone volume

An implant is a titanium post that fuses with your jawbone (a process called osseointegration). If there isn't enough bone to grip, it can't work. Bone shrinks after tooth loss, fastest in the first year, which is why implant dentists quietly wince when someone says "I've had this gap for fifteen years."

Insufficient bone doesn't automatically rule you out. Bone grafting and sinus lifts rebuild volume (adding cost and healing time), and techniques like zygomatic or pterygoid implants exist for severe upper-jaw bone loss. A 3D CBCT scan settles the question in minutes, so never accept a suitability verdict without one.

Gum health: the non-negotiable

Active gum disease (periodontitis) must be treated and stabilised before implants are placed. Implanting into inflamed gums significantly raises the risk of peri-implantitis, the leading cause of late implant failure. The good news: treated, controlled gum disease is a green light, not a red one.

Smoking: the unvarnished version

Smoking roughly doubles implant failure rates. The mechanism is reduced blood flow, which impairs bone healing and integration. Most clinics will still treat smokers, but the good ones will tell you the numbers and strongly encourage quitting, or at least stopping through the healing phase. Vaping is gentler but not neutral. If you smoke, factor this into your decision openly rather than hoping it away.

Medical conditions

• Diabetes: well-controlled diabetes (sensible HbA1c) is generally fine. Poorly controlled diabetes impairs healing and raises failure risk, so get control first.
• Bisphosphonates and similar bone medications (used for osteoporosis and some cancers) require careful assessment because of a rare risk of jaw bone problems after dental surgery. Tell your implant dentist everything you take.
• Radiotherapy to the jaw needs specialist management but isn't always a barrier.
• Blood thinners are usually managed rather than being a barrier. Full disclosure is key.
• Autoimmune conditions and steroids are case-by-case; healing capacity is the question.

Age: mostly a myth

There is no upper age limit. Implant dentists routinely treat patients in their 80s, and the oldest well-documented cases are older still. The only real age barrier is the lower one: jaws must have finished growing, so implants are almost never placed before 18 to 21.

Grinding (bruxism)

Heavy grinders can have implants but need planning, because the forces involved can overload a crown. Expect discussion of a night guard, and possibly a different restoration design.

When implants genuinely aren't the answer

A proper assessment means admitting the alternatives sometimes win. A conventional bridge may suit a single gap with strong neighbours. Modern dentures have improved enormously for full-arch loss at a fraction of the cost. And sometimes the right answer is to stabilise gum disease first and revisit implants in a year. A clinic that never says "actually, implants aren't your best option" is a clinic that sells implants rather than solutions.
