Many people with diabetes assume dental implants are off the table. That assumption is usually wrong. What matters clinically is not whether you have diabetes, but how well it is controlled — and that distinction changes the conversation entirely.
Dr. Jin-Ho Cho at Shine Dental Newington — BDS (University of Sydney, 1987), more than 35 years in practice, over 9,000 implant fixtures placed — reviews medical history in detail at consultation, and diabetes is one of the conditions that most often shapes planning.
Why does blood sugar affect implant healing?
An implant fuses with bone over months. That process depends on blood supply, immune function and the activity of bone-forming cells.
Persistently raised blood glucose interferes with all three. It affects small blood vessels, reducing circulation to the healing site. It impairs the function of white blood cells, which matters when a surgical wound is exposed to a mouth full of bacteria. And it slows the formation of collagen and new bone.
There is also a two-way relationship with gum disease. Poorly controlled diabetes increases susceptibility to gum disease, and gum inflammation in turn makes blood sugar harder to control. Since gum health around an implant determines much of its long-term outlook, this loop is directly relevant.
Does well-controlled diabetes change the picture?
Substantially. The research literature draws a consistent distinction: patients with well-controlled diabetes show implant outcomes broadly comparable to patients without diabetes, while poorly controlled diabetes is associated with slower healing and higher failure rates.
This is why a dentist will ask about your recent HbA1c rather than simply whether you are diabetic. HbA1c reflects average blood glucose over roughly the preceding three months, which is a more meaningful figure for a healing process measured in months than a single day's reading.
Individual outcomes still vary. A favourable HbA1c improves the odds; it does not settle the result in advance, and no honest practice will suggest otherwise.
What should I bring to the consultation?
Useful information to have ready:
- Your type of diabetes and how long you have had it.
- Your most recent HbA1c, and whether it has been stable.
- All medications, including insulin, oral agents and anything else you take. Some medications affect bleeding or bone metabolism.
- Your GP or endocrinologist's details, in case coordination is helpful.
- Any history of slow healing, previous infections or complications after surgery.
Bringing this to the first appointment saves time and produces a more realistic plan.
Will the treatment plan be different?
It may be, in a few ways.
Timing. If control is currently poor, the sensible recommendation is often to improve it before elective surgery rather than proceed and hope. This is a delay, not a refusal, and it usually improves the outcome.
Appointment scheduling. Morning appointments are often preferred, and you should eat and take medication as normal beforehand unless specifically advised otherwise. Turning up fasted for a dental procedure is a common and avoidable mistake.
Healing periods. Longer integration times may be allowed before loading the implant.
Infection management. Preventive measures around surgery may be adjusted. Any decision about antibiotics is a clinical judgement made for the individual case.
Follow-up frequency. More frequent reviews after placement, since early detection of a problem matters more when healing is slower.
What about gum health around the implant afterwards?
This is the part that deserves as much attention as the surgery.
Peri-implantitis — inflammation of the gum and bone around an established implant — is the main cause of late implant loss, and diabetes increases susceptibility to it. That makes the ongoing routine more important, not less: thorough daily cleaning around the implant, professional maintenance visits at the interval your dentist recommends, and prompt attention if the gum becomes red, swollen or bleeds.
Our guides on caring for implants and peri-implantitis cover the practical routine.
Are there alternatives if implants are not advisable?
Yes, and they deserve genuine consideration rather than being treated as consolation. A dental bridge does not depend on bone integration. Removable options, including implant-retained dentures where fewer implants are workable, may suit some situations.
The purpose of the assessment is to lay out what is realistic for you, which sometimes means recommending against the treatment you came in asking about.
Working with your doctor
Dental treatment does not happen in isolation from the rest of your health. Where your control is borderline or your medical history is complex, coordination with your GP or endocrinologist is sensible before elective surgery. Nothing in this article replaces advice from the doctor who manages your diabetes.
Arranging an assessment
Planning includes a CBCT scan taken on site and a written, itemised quote with item numbers before anything is booked. HICAPS on-the-spot claiming is available, and the practice is a CBHS and NIB preferred provider. Consultations run in English or Korean.

Treatment described here depends on an individual clinical and medical assessment, and outcomes vary between patients.
