Dental Implants · Suitability

Are You a Candidate for Dental Implants?

Dental implants suit many adults, but they are not the right answer in every case. Suitability is decided by a careful assessment — bone, gum health, general health, smoking, age, bite, and your willingness to commit to the process and the maintenance.

This page walks through the main factors your dentist will consider, situations where implants may not be appropriate, and what to expect from an implant suitability assessment. To have your own situation assessed in person, book a consultation online or phone the practice.

The starting point — a thorough assessment

There is no online quiz that will tell you whether implants are right for you. The decision rests on a clinical examination, imaging, your medical history, and a conversation about your goals. At Sandgate Family Dental, an implant suitability appointment usually includes:

  • A full mouth examination, including the teeth around the gap and the opposing teeth
  • A periodontal (gum) assessment
  • Digital imaging, and a 3D scan where bone needs to be assessed in detail
  • A review of your medical history, current medications, and lifestyle factors
  • A discussion of your priorities, time frame, and budget

From there, your dentist will explain what is realistic in your case and where collaboration with a colleague with specialist training in implant surgery may be appropriate.

Bone — how much, and what quality

An implant relies on having enough good-quality bone to support it. Bone loss is common after a tooth has been missing for some time, and it can also follow long-term gum disease or trauma. Your dentist will assess:

  • The height and width of bone in the area where the implant would sit
  • The position of nearby anatomical structures such as the sinus or major nerves
  • The density of the bone, which affects how predictably the implant will integrate

If there is not enough bone in the right place, a bone graft or sinus lift may be considered to build up the area first. This is a planning decision rather than a barrier — many patients with initial bone limitations go on to have successful implants after preparation.

Gum health

The gums and the bone around teeth are closely linked. Active gum disease must be brought under control before implants are placed. The same bacteria that drive periodontal disease can drive disease around an implant (peri-implantitis), so going into implant treatment with healthy, stable gums is non-negotiable. This may include:

General health

Implants involve a minor surgical procedure and a healing period, so general health is part of the picture. Conditions and medications that can affect implant planning include:

  • Poorly controlled diabetes (well-controlled diabetes is usually fine, but the control matters)
  • Conditions affecting healing or the immune system
  • Some bone-modifying medications used for osteoporosis or certain cancers
  • Long-term steroid therapy
  • Recent radiation therapy to the head or neck
  • Bleeding disorders or medications that affect bleeding

None of these is automatically a reason to rule out implants — but they are reasons to discuss the case more carefully with your dentist and, where appropriate, your medical team.

Smoking

Smoking is one of the strongest individual factors that affects implant outcomes. It reduces blood flow to the gums, slows healing, and significantly increases the risk of implant complications and long-term peri-implantitis. We do not refuse to treat smokers, but we will be honest about the increased risk and we encourage quitting — or at least pausing — around the time of surgery. The closer you can get to being a non-smoker through implant placement and healing, the better the outlook.

Age

  • Young patients: Implants are usually placed once jaw growth is complete, typically late teens or early twenties depending on the individual. Placing an implant too early can leave it looking shorter than the neighbouring teeth as the rest of the face continues to develop.
  • Older patients: Age alone is not a barrier. Many implants are placed for patients in their seventies and eighties. What matters is general health, bone, gum health, and the patient’s wishes — not the date on the chart.

The bite, clenching, and grinding

Implants sit in bone but do not have the cushioning ligament that natural teeth have, which means heavy bite forces are felt more directly. Where clenching or grinding (bruxism) is part of the picture, your dentist will usually:

  • Assess wear patterns on the teeth and any signs on the jaw joint
  • Discuss the use of a nightguard after implant placement to protect the restoration
  • Adjust the bite carefully when fitting the crown

The state of the rest of the mouth

Implants do best in a healthy mouth. Where there are other issues — fractured teeth, large old fillings, untreated decay, or failing restorations — these are usually addressed before or alongside implant planning. The aim is a stable foundation, not a patch-up.

Your commitment to the process

Implants are a multi-month treatment with several appointments and a long-term maintenance commitment. Suitability is not only clinical — it also depends on:

  • Whether the timeline works for you
  • Whether you are willing and able to keep up daily home cleaning
  • Whether you can commit to regular professional cleans
  • Whether you are comfortable with the surgical step

For patients who would prefer to avoid surgery, a bridge, denture, or other restoration may be a better fit. Our implant vs bridge and implant vs denture pages compare them.

When implants may not be the right answer

There are situations in which implants are usually deferred, modified, or set aside altogether — for example:

  • Active uncontrolled gum disease (treat first, then reassess)
  • Recent or planned high-dose radiation therapy to the jaws
  • Heavy active smoking with no intention to reduce
  • Severe bone loss where grafting is not realistic or wanted
  • Significant uncontrolled medical conditions that affect healing
  • Young patients whose growth is not complete
  • A clear patient preference for a non-surgical solution

Being unsuitable today does not mean being unsuitable forever. Many situations can be improved with treatment, lifestyle change, or planning.

What happens after the assessment

After your suitability assessment, you should leave with:

  • A clear understanding of whether implants are realistic in your case
  • A written plan if you are proceeding, including each stage and item number
  • Honest alternatives if implants are not the best fit
  • Time to think it over — there is rarely a clinical urgency to decide on the day
Payment

Health funds and payment

We are HICAPS providers. Rebates for implant treatment depend on your individual policy and on lifetime or annual implant limits — many funds have these specifically. Our implants and your health fund page covers this in detail, and our implant cost and funds page explains the cost structure.

FAQs

Implant suitability FAQs

Can I have implants if I have lost bone where the tooth used to be?

Often yes. A bone graft can be planned to build up the area before the implant is placed. The first step is a 3D scan so the bone can be assessed properly.

What if I have gum disease?

Implants are not placed while gum disease is active. The gums are treated first and stabilised, and then implant planning can proceed if appropriate.

Can I have implants if I smoke?

Smoking significantly increases the risk of implant complications. We do not refuse to treat smokers, but we will discuss the risks honestly and encourage you to stop, or at least pause, around the time of treatment.

I have diabetes — does that rule me out?

Well-controlled diabetes is usually compatible with implant treatment. The level of control is what matters, not the diagnosis alone.

I take a bone-modifying medication — what should I do?

Tell your dentist. Some medications used for osteoporosis or certain cancers can affect jaw healing. Your dentist may liaise with your prescriber before recommending treatment.

Am I too old for implants?

Probably not. There is no fixed upper age limit. What matters is your general health and your wishes.

I am only a teenager — can I have an implant?

Usually implants are deferred until jaw growth is complete, typically late teens to early twenties. A temporary solution can usually be planned in the meantime.
