What Actually Happens in a Candidacy Evaluation
Most people worry about being turned down, so it helps to know that candidacy is decided in an evaluation — not by a website, a photo, or a phone call. A typical first evaluation blends a conversation, a clinical exam, and imaging.
You'll usually be asked about your medical and dental history, so bring a current list of medications, any diagnoses you carry, and dental records if you can. The dentist examines your teeth and gums for signs of gum disease, infection, loose teeth, or existing dental work that could complicate a placement. Then imaging takes over where the eye can't see. Many practices use a 3D cone-beam CT scan to measure bone in three dimensions — how thick or thin it is, where the sinus cavity sits in the upper jaw, and where nerves run in the lower jaw. That level of detail is a big reason evaluations tend to end with a clear recommendation rather than a maybe, and it's also why you should expect the dentist to explain findings as they go. Some evaluations span more than one visit, so a firm answer on the first day isn't always realistic.
The Bone Factor: Why Your Jawbone Decides So Much
The single biggest reason candidacy is individualized is bone. Implants work through osseointegration — the process where a titanium post fuses with living bone and effectively becomes part of the jaw. That fusing gives the crown attached to the post its anchor. For it to happen, the bone has to be dense and deep enough to hold and support the post.
Bone loss is common, which is often what patients worry about most. The bone that once supported a tooth begins to shrink after the tooth is removed, and untreated gum disease can erode supporting bone over time. In the upper jaw, the sinus cavity can limit how much bone is available. But finding that bone is insufficient does not mean implants are off the table. In some cases a bone graft can build up the site first, and candidacy is reassessed after healing. In others, the dentist may recommend a different path. Whether grafting is possible depends on your anatomy, your health, and the extent of the loss — which is exactly why this is decided per case, not by a general rule.
Gum Health, Health Conditions, and Habits: Risk Factors, Not Rules
Implants need stable supporting tissue, much like a natural tooth does. Active, untreated gum disease is typically addressed before implant placement is even considered — treatment happens first, then the dentist reassesses whether you're a candidate. Treating gum disease is often a step in the plan rather than a reason to rule you out.
The same case-by-case logic applies to health conditions and habits. Diabetes, especially when blood sugar isn't well controlled, and smoking can slow healing and raise risk. But the dentist looks at how a condition is managed, not just whether it exists — well-controlled diabetes presents a different picture than uncontrolled diabetes. Smoking affects blood flow and healing, so a dentist may discuss ways to reduce risk or time the procedure accordingly. Certain medications can also affect healing, which is why the complete medication list you bring, including supplements, matters. None of these automatically disqualify you. Dentists weigh them as risk factors in the context of everything else — your bone, your gums, your overall health. Age alone doesn't rule anyone out either; what matters is the state of your mouth and body at the time of the evaluation.
When Implants Might Not Be the Right Path
There are realistic limitations, and a good evaluation is honest about them. If bone loss is severe and grafting isn't a workable option, or if a health condition significantly impairs healing, a dentist may recommend against implants or suggest waiting until the situation improves. In some situations, the first step is managing a condition or habit before candidacy is revisited. If implants aren't recommended, a responsible clinician explains why and walks you through the alternatives that fit your situation better. The goal is to find what is most likely to work for you, not to place an implant at any cost. Because eligibility depends on individual anatomy, health status, and the evaluating clinician, two people with similar circumstances can walk away with different recommendations — and both can be reasonable.
Questions to Ask at Your Consultation
A consultation is your chance to hear the reasoning behind a recommendation. Useful questions include:
- What imaging do you recommend, and what will it show about my bone?
- If my bone is insufficient, what are my options, and how is that decision made?
- Which health conditions or habits could affect my healing, and what can I do to improve my chances?
- What does the overall timeline look like from evaluation through placement?
- What specific risks apply to my situation?
- If gum disease or another issue needs treatment first, how will we know when it's time to reassess?
- Who would perform the placement, and what does that part of the process involve?
Answers will vary from person to person, and that variation is expected rather than a sign something is wrong. Write the answers down or bring someone along to help you remember them.
After the Consultation: What to Expect Next
When you leave, ask for the reasoning behind the recommendation and the steps that follow — whether that's grafting, treating gum disease first, or a different treatment altogether. If a second opinion would help you feel confident, that's a normal part of the process, not a sign of trouble. Health information is easy to misstate, so let your clinician's assessment guide you rather than generalized claims you may read elsewhere. This article is educational and does not replace a dentist's or periodontist's clinical judgment. Eligibility decisions vary by individual anatomy, health status, and the evaluating clinician — the consultation is where your real answer lives.
