Can anyone have a dental implant? Who qualifies, who has to wait, and who needs a different plan

Hardly anyone asks “am I suitable?” out of curiosity. They ask because something happened.

A dentist mentioned in passing that there might not be enough bone. A relative was turned down somewhere. Someone read that smokers cannot have implants, or that diabetes rules them out, or that you have to be under a certain age. And then the question sits there for months, unasked, while the gap stays where it is.

So it is worth saying clearly at the start: implantology in Germany is not a gate with a bouncer. It is a planning discipline. The overwhelming majority of consultations that begin with “I was told I probably can’t” end with a plan — sometimes a longer one, sometimes with an extra preparatory step, occasionally with a different solution that suits the situation better. What you need is not a verdict. It is an assessment.

Bone. An implant is a screw anchored in the jawbone. It needs sufficient bone height, width and quality around it, and a safe distance from anatomical structures — the nerve canal in the lower jaw, the sinus in the upper. This is measured, not guessed, which is why a 3D X-ray (DVT) is central to the assessment rather than optional.

Gums and the mouth around the site. An implant does not decay, but the tissue holding it can become inflamed. Active gum disease (Parodontitis) is therefore treated before an implant is placed, not afterwards. So is untreated decay elsewhere in the mouth, because bacteria do not respect the boundaries of a treatment plan.

Your general health and the medication you take. Healing is a whole-body process. Anything that affects wound healing, bone metabolism, immune response or bleeding matters here — which is why the medical questionnaire in an implant consultation is longer than the one for a filling, and why it is worth filling in properly.

Everything else people worry about — age, a crown that looks different, how long ago the tooth came out — sits downstream of these three.

When a tooth is lost, the bone that used to hold it slowly reduces, because the stimulus of chewing through the root is gone. The longer a gap has been there, the more likely it is that bone volume has changed. This is normal biology, not neglect, and it is the single most frequent reason someone is told an implant is “difficult”.

It is rarely the end of the discussion.

Bone grafting (Knochenaufbau) rebuilds volume where it is short, either in a separate step before the implant or at the same appointment, depending on how much is needed. In the upper jaw the sinus floor can be raised to create height (a sinus lift). In the lower jaw, planning is dominated by the nerve canal and the width of the ridge. As a general market range in Germany — not our prices — bone grafting sits somewhere between 500 and 2,500 €, and it adds time as well as cost, because grafted bone needs its own healing period before it can carry an implant.

There is also a growing set of situations where grafting can be avoided: shorter or narrower implants, angled placement, or positioning that uses the bone that is still there rather than rebuilding what is gone. Whether that applies to you is a question of millimetres on a 3D scan, which is exactly why the scan comes before the promise. We look at that question in detail in Can implants be placed without bone grafting?.

This is the condition patients push back on most, so it deserves a proper explanation rather than a rule.

Periodontitis is a bacterial inflammation that destroys the attachment between tooth and bone. An implant placed into a mouth where that process is still active is exposed to the same bacteria. The equivalent condition around an implant — peri-implantitis — behaves similarly and is one of the main reasons implants are lost years after they were placed. German dental associations are consistent on the sequencing: stabilise the gums, then implant.

In practice that means a periodontal treatment programme, a reassessment, and often a professional cleaning (professionelle Zahnreinigung, PZR) rhythm that continues afterwards for the life of the implant. It adds months to the timeline. It also substantially changes the odds, which is why it is not a delaying tactic.

Having had periodontitis does not disqualify you. Having it untreated at the moment of surgery is the problem. Patients with a history of gum disease can and do have successful implants — with closer aftercare intervals and a maintenance routine they stick to.

The honest summary of this whole section: very few medical conditions are an outright “no”, and quite a few are a “yes, with these precautions”. What matters is that your dentist knows about them.

Well-controlled diabetes is not a barrier to implants. Poorly controlled diabetes affects wound healing and infection risk, and that is what raises the stakes — the diagnosis itself matters less than the control. In practice this means your dentist will want to know your current HbA1c and will often coordinate with the doctor treating your diabetes before surgery. Many patients with diabetes have implants placed successfully; the difference is preparation and a slightly closer eye on healing. There is a dedicated article on this: Dental implants with diabetes.

Osteoporosis by itself is generally not a reason to rule out an implant. What requires careful thought is a specific group of bone-modifying drugs — bisphosphonates and related medicines, particularly in high-dose or intravenous form, which are used in osteoporosis and in some cancer treatments. They change how the jawbone remodels and carry a recognised risk in jaw surgery. This is genuinely important: tell your dentist about every such medication, including infusions you had years ago, because they stay relevant long after the last dose. It does not automatically mean no implant. It means the decision is made together with your treating physician.

Anticoagulants and platelet inhibitors are extremely common and are not an obstacle to implant surgery as such. They are a reason for planning: the surgical approach is adapted, and any adjustment to medication is decided by the doctor who prescribed it — never by you and never unilaterally by the practice. The same applies to heart valve conditions or replacements, where antibiotic prophylaxis may be indicated. Bring the exact drug names and doses to your consultation.

Immunosuppressive therapy after a transplant, ongoing chemotherapy, or previous radiotherapy to the jaw region all change how bone and soft tissue heal. Radiotherapy to the jaw in particular requires specialist assessment and, in some situations, a different approach entirely. These are the cases where a straightforward yes is least likely and where coordination with the treating clinic is not a formality.

Smoking does not disqualify you, and no honest article should pretend otherwise. It does measurably affect healing of the soft tissue and is associated with a higher rate of complications around implants. Stopping — or substantially reducing — around the surgical and healing phase is one of the few things fully within your own control that changes your odds. Most dentists will say this plainly and then treat you either way.

Too old? There is no upper age limit for a dental implant. What matters is general health and the ability to sit comfortably through a short surgical appointment, not the year on your ID. Implants are routinely placed in patients well into their seventies and eighties, often to stabilise a denture (Prothese) that has stopped sitting properly.

Too young? Here there is a real limit. Implants are not placed while the jaw is still growing, because a natural tooth moves with the growing jaw and an implant does not — it stays where it was put, and the result becomes visible over years. Completion of jaw growth is assessed individually rather than by a birthday, and it typically happens later in young men than in young women. For an adolescent who has lost a front tooth, the usual approach is a well-made temporary solution until growth is complete.

Pregnancy. Elective surgery is normally postponed. Nothing about an implant is urgent in the way an infection is, and there is no good reason to schedule anaesthetic, X-rays and a surgical procedure during pregnancy when it can wait. Acute problems are of course treated — that is a different question.

Short, honest list. Very little belongs on it permanently.

Notice what is not on this list: age, a metal allergy (ceramic implants exist for exactly that reason), having lost the tooth a long time ago, or having been told “no” somewhere else without a 3D scan.

A proper assessment is not a glance in the mouth.

It starts with the consultation: what you want, what happened to the tooth, what else is going on in your mouth, and — at length — your medical history and every medication you take, including supplements and anything by injection or infusion. Then imaging: a 3D X-ray (DVT) shows bone height, width and density, and the position of the nerve and sinus, in a way a flat X-ray cannot. In our practice a DVT costs 178 €, and the first consultation is free, so the assessment itself does not commit you to treatment. Where a case is complex, we plan it digitally and place the implant with a surgical guide, and scan review is supported by AI analysis alongside the dentist’s own assessment — never instead of it.

Out of that comes one of three answers: suitable now; suitable after a preparatory step, with the step and its timeline named; or better served by an alternative, with the reasoning explained. You should leave with a written treatment and cost plan (Heil- und Kostenplan, HKP) rather than an impression.

Two practical things trip people up here, and neither is medical.

Your medical history is somewhere else. If you were treated abroad, bring what you have — medication names, previous X-rays, the name of any bone-modifying drug or cancer therapy. Drug brand names differ between countries; the active ingredient is what your dentist needs, and it is printed on every package. A photo of the box works.

Suitability is a conversation, not a form. This is precisely the appointment where nuance matters — “sometimes”, “how well controlled”, “how long ago”. If discussing your health in German would flatten those nuances, have the conversation in a language you think in. Expats commonly travel half an hour for that, and for implant work patients come to Wuppertal from across NRW — Düsseldorf, Cologne, Bonn — and from further afield in Germany. Where to look: English-Speaking Dentist in NRW.

Ordinary swelling, mild bruising and moderate soreness in the first few days are expected and not a warning sign. The pattern to watch for is symptoms that worsen instead of easing.
