Who May Be Suitable for Dental Implants?

Dental implants can be an excellent way to replace missing teeth, but suitability is individual. Most adults can be considered, although some factors increase the risk of complications and need careful assessment — and sometimes treatment — before implants are placed.

The short answer

Adults with missing teeth, healthy gums, adequate bone (or suitability for bone grafting) and reasonable general health are often suitable. Smoking, poorly controlled diabetes, certain medications and untreated gum disease increase risk and need careful assessment.

Factors that support suitability

• Jaw growth is complete — implants are generally placed once growth has finished, usually in adulthood
• Healthy gums, or gum disease that has been treated and stabilised
• Adequate bone height and width, confirmed by imaging
• Good oral hygiene and commitment to maintenance
• Reasonable general health for minor oral surgery

Factors needing careful assessment

Smoking

Smoking reduces blood flow to the gums and bone and is associated with higher implant failure rates and more complications. Stopping smoking — or at least stopping around the time of surgery — can improve outcomes.

Diabetes

Well-controlled diabetes does not necessarily prevent implant treatment. Poorly controlled diabetes can impair healing and increase infection risk. Your dentist may ask about your recent blood sugar control.

Medications affecting bone

Some medications used for osteoporosis or cancer (such as certain bisphosphonates and other antiresorptive drugs) are associated with a rare but serious condition called medication-related osteonecrosis of the jaw. Your dentist needs to know if you have taken these.

Blood thinners

Anticoagulant and antiplatelet medications affect bleeding. Do not stop them without medical advice; your dentist will plan around them.

Previous radiotherapy

Radiotherapy to the head and neck can affect bone healing and needs specialist assessment.

Gum disease

Active periodontal disease increases the risk of peri-implantitis and must be treated before implants.

Bone loss

After a tooth is lost, bone gradually shrinks. If there is not enough bone, grafting or alternative approaches may be needed.

Grinding

Heavy grinding or clenching places extra force on implants and their crowns. A night guard and careful planning may be recommended.

Age

There is no upper age limit for healthy adults. Many older patients benefit from implants, particularly to stabilise dentures. General health matters more than age.

How suitability is assessed

• Medical history and medication review
• Clinical examination
• 3D imaging of bone
• Discussion of risks and alternatives

Conclusion

Suitability for implants is individual and depends on your health, bone and gums. A thorough assessment will show whether implants are right for you and what preparation might be needed. Learn more about implants or book an implant consultation.
