Implants and Your Health

Can you have implants if you have diabetes?

What decides it is not whether you have diabetes, but whether your blood sugar is under control

Most patients with diabetes come to us with this question, and many of them have already been told somewhere that it cannot be done. The truth is this: diabetes on its own is not a barrier to implants. The barrier is uncontrolled blood sugar. On this page we explain the difference, how healing changes, how to prepare for the day of your appointment and what to look out for in the long term.

Short answer

Implant treatment can be carried out in people with diabetes whose blood sugar is under control. With uncontrolled diabetes, however, healing is delayed, the risk of infection rises and the tissues around the implant are more easily affected by disease, so the plan is postponed until your readings are back on track. Your dentist looks at your HbA1c, the medicines you take and the health of your gums together. Postponing is not cancelling the treatment; it is protecting its chances of success.

What decides it: Whether your blood sugar is under control
What is checked: HbA1c and your recent blood sugar monitoring
If it is uncontrolled: Delayed healing, a higher risk of infection
On the day: A morning appointment, with no missed medicines or meals

What diabetes does in the mouth

High blood sugar affects the smallest branches of the blood vessels, the capillaries. The gums and the jawbone are also fed by this circulation. In tissue whose blood supply is impaired, two things happen at once: healing slows down and it becomes harder for immune cells to reach the area. This is why gum disease is both more common and progresses faster in people with diabetes.

Nor does the relationship run in one direction only. Advanced gum disease creates an ongoing source of inflammation in the body, and that inflammation makes blood sugar harder to control. In other words, the condition of the mouth makes diabetes worse, and diabetes makes the condition of the mouth worse. This cycle explains why, for people with diabetes, gum treatment is not just about the mouth.

Where implants are concerned, there are two critical periods. The first is healing after surgery: what is expected here is for the wound to close and the bone around the implant to settle. Uncontrolled blood sugar makes this period longer and increases the chance of infection. The second is the long term: inflammation around the implant (peri-implantitis) is reported more often in people with diabetes, and this is where regular maintenance becomes all the more important.

So what does 'under control' mean? Your dentist does not look at a blood sugar reading from a single day, but at your HbA1c, which shows the average over the last two to three months. Alongside this, they consider how regularly you monitor your blood sugar, whether you have had episodes of hypoglycaemia and the medicines you take. The decision rests on all of this information and, if needed, on a discussion with your internal medicine specialist.

Another common issue for people with diabetes is dry mouth. When there is less saliva, the mouth is less able to clean and buffer itself, and the chance of tooth decay, gum disease and fungal infection all goes up. For people with diabetes who wear a removable denture, this also makes it easier for the denture to rub and cause sores. For these patients, moving to a fixed solution has added value.

Let us be clear about this: it is not right for you to be turned away because you have diabetes, but nor is it right for you to be taken straight into surgery while your readings are borderline or uncontrolled. The right approach is to get things under control together and build the plan around that. In a patient whose readings improve, treatment goes well; treatment carried out before they improve is unfair to both the patient and the implant.

Who can go ahead now, and who needs to prepare first

The distinction below is the framework for the assessment made at the consultation. The final decision is made once your HbA1c, the condition of your mouth and your general health have been looked at together.

The tooth can be saved

Patients whose blood sugar is monitored regularly and is under controlIn a patient whose readings stay within the target range, implant treatment can be carried out, and healing largely follows the same course as in patients without diabetes. Check-ups are kept a little more frequent.
People with healthy gumsThe picture is favourable for patients who, although they have diabetes, have no gum inflammation and look after their mouth regularly. In this group, oral care habits are the most important factor in how long the implant lasts.
Plans carried out together with your internal medicine specialistWhen the clinic is in contact with the doctor who manages your diabetes, both the timing of the surgery and your medication routine can be set correctly. This cooperation makes the treatment directly safer.
Patients with diabetes who struggle with a removable dentureIn a patient with a dry mouth, a removable denture is more likely to cause sores and infection. For this group, moving to a fixed solution is a gain not only in comfort but also in the health of the tissues.

Saving it is unlikely to hold

Patients whose blood sugar is uncontrolledWith high, fluctuating readings, healing is delayed and the risk of infection rises. In this situation the right decision is to wait; once the readings are back on track, the same plan can go ahead.
People with active, advanced gum diseasePlacing an implant in an inflamed base both lowers the chance of the surgery succeeding and, in the long term, leaves conditions open to peri-implantitis. Gum treatment is completed first.
People who often have episodes of hypoglycaemiaA drop in blood sugar during a long session is a separate risk. In this situation, your blood sugar needs to settle into a steady pattern first, the session plan needs to be shortened and, if needed, your medication routine needs to be adjusted.
If you smoke as well as having diabetesWhen the two risk factors come together, their effects do more than simply add up. In this group, the likelihood of implant loss and peri-implantitis rises markedly; stopping smoking should be discussed before treatment.

Preparation and the day of your appointment

For people with diabetes, the safety of treatment depends largely on planning. The following are standard practice.

1
An up-to-date HbA1c and list of medicines
An HbA1c result from within the last three months and a list of all the medicines you take. If you use insulin, the doses and times should be written down too. This information is the foundation of the plan.
2
Assessing the health of your gums
Any inflammation in the mouth is dealt with before the implant. Scaling and, if needed, gum treatment are completed before surgery; for people with diabetes, this step cannot be skipped.
3
Talking to your internal medicine specialist if needed
If your readings are borderline or your medication routine needs adjusting, the clinic gets in touch with the doctor who manages your diabetes. This directly determines the timing and safety of the surgery.
4
Booking a morning appointment
Mornings are more predictable for blood sugar and also leave you the rest of the day to keep an eye on how you are. In long sessions, breaks can be taken to check your blood sugar.
5
Keeping to your usual meals and medicines
Do not come on an empty stomach. Have your normal meal and take your medicine as usual; unless you have been told otherwise, do not change your insulin dose on your own. Bring your meter and a source of fast-acting sugar with you.
6
Eating and monitoring plan after surgery
Because you will need soft foods in the first few days, your meal plan is discussed in advance. You will be asked to check your blood sugar a little more often during these days; the stress of surgery can raise your readings temporarily.

Plan options for people with diabetes

These are the routes discussed for this group, and each has its own implications where diabetes is concerned.

Implants once your readings are under control

The route chosen most often. A few months spent getting things under control markedly increases the chance of the treatment succeeding. This time is not wasted; gum treatment and a care routine are set up during the same period.

Planning that does not need a bone graft

Adding bone means an extra operation and months of extra healing. For a patient whose healing is already slow, avoiding this step is a real advantage. When the anchorage is taken from the deep cortical and basal layer that does not shrink, a bone graft does not come into it in most cases.

Keeping treatment time short

Reducing the number of operations and healing periods shortens the total time a patient with diabetes is exposed to risk. This is the aspect of a plan that fits into three clinical days that deserves particular consideration for this group.

Removable implant-retained denture

An in-between solution that gives stability with a small number of implants. The surgery is smaller in scope; the trade-off is that the denture remains removable and there is still a surface resting against the soft tissue of the mouth.

Full removable denture

The route with no surgery. Because rubbing and sores from the denture are more common in patients with diabetes who have a dry mouth, it can be hard going for this group in terms of comfort; it also does not stop bone loss.

Risks you should know about

The following occur more often in people with diabetes. None of them is inevitable; all of them can be kept under control.

Delayed healing

Because the capillary circulation is affected, wound healing slows down. This does not mean the treatment cannot be done; it means allowing a little more time for healing and having check-ups more often.

A higher risk of infection

When it is harder for immune cells to reach the area, the chance of infection rises. That is why oral hygiene, not missing any of the medicines you are given and an early check-up are more critical for this group.

A tendency towards peri-implantitis

The point that needs the most attention in the long term. Because it progresses silently, the patient does not notice it; the only things that catch it early are regular check-ups and pocket measurements.

Dry mouth

When there is less saliva, the chance of tooth decay, gum disease and fungal infection all goes up. Drinking water, saliva substitutes if needed and a review of your medicines all help here.

Healing and long-term care

Healing is no different for people with diabetes; it is simply followed more closely.

The first few days
The stress of surgery can raise your blood sugar temporarily; you will be asked to check it more often during these days. While you are on soft foods, take care to keep to your usual meal routine and the amount of carbohydrate you eat.
The first week
The swelling goes down and the pain eases. Anything outside what is expected during this time, such as increasing swelling, a fever or a bad taste, should be reported straight away; in people with diabetes, infection can progress faster.
The first months
Check-ups are kept more frequent than for patients without diabetes. At each one, the health of your gums, the pocket depths and the bone level around the implants are assessed.
The long term
Professional maintenance at least twice a year is recommended. The aim is to catch peri-implantitis while it is still at an early stage; with this condition, the difference between acting early and acting late is the difference between keeping the implant and losing it.

Message us right away if

You have a fever or increasing swelling while healing. In people with diabetes, infection can progress faster. Call your clinic without waiting; if the swelling is spreading towards your eye or neck, go straight to A&E.
Your blood sugar has got out of control. If your readings go outside the expected range after surgery, let both your dentist and the doctor who manages your diabetes know. The two should decide together.
Your gums have started to bleed or recede. This is the first sign of peri-implantitis, and it is seen more often in this group. Acting early resolves it without losing anything; if you wait, it goes on to bone loss.
You have a dry or burning mouth, or white patches. A dry mouth can pave the way for a fungal infection. These signs can be treated, and if they are ignored they also affect the tissue around the implant.

What affects the cost

Diabetes does not change the price of treatment directly; what it affects is the preparation stage and the check-up routine. These are the items:

Preparation and gum treatment: Clearing up inflammation in the mouth before the implant is a step that cannot be skipped for this group. Its extent depends on the condition of your mouth, and it may be a separate item.
Whether extra procedures are needed: A plan that requires adding bone increases both the cost and the healing time. For a patient whose healing is already slow, avoiding this step is a gain on both fronts.
How often you have check-ups: For people with diabetes, check-ups are kept more frequent. This means the long-term maintenance item is a little larger; in return, it directly extends the life of the implant.
How long treatment takes: In a plan spread over months, travel, time off work and repeated sessions all add to the total. In a short plan, these items get smaller.

Frequently asked questions

I have diabetes. Does that mean I can't have implants?

You can. What decides it is not whether you have diabetes, but whether your blood sugar is under control. Treatment goes ahead for patients whose readings stay within the target range, and healing largely follows the expected course. With uncontrolled readings, however, the plan is postponed.

What should my HbA1c be?

It would not be right to give a single cut-off; the decision is made by looking at your HbA1c together with how regularly you monitor your blood sugar, your history of hypoglycaemia, the medicines you take and the condition of your mouth. This assessment is often made together with the doctor who manages your diabetes.

Is my implant more likely to fail?

With uncontrolled diabetes, yes; the reason is delayed healing and a higher risk of infection. For patients whose diabetes is under control, this difference becomes markedly smaller. The two things with the biggest effect are how steady your blood sugar is and whether you smoke.

Should I come without eating on the day of surgery?

No. Unless you have been told otherwise, have your normal meal and take your medicines as usual. Coming on an empty stomach increases the risk of hypoglycaemia. Bring your meter and a source of fast-acting sugar with you; if sedation is planned, you will be given separate fasting instructions.

Should I change my insulin dose?

Do not change it on your own. If an adjustment is needed, it is made together with the doctor who manages your diabetes. Because what you eat changes in the first few days after surgery, your insulin routine may need to be reviewed; talk about this in advance.

Will it take me longer to heal?

With uncontrolled readings, yes. For patients whose diabetes is under control, healing is usually complete within the expected time. Even so, check-ups are kept more frequent and a little more time is allowed for healing.

Do I need different care in the long term?

Yes, and this is the most important point. Peri-implantitis is seen more often in this group and progresses silently. At least two professional maintenance appointments a year, cleaning between your teeth every day and keeping your blood sugar steady: how long the implant lasts depends largely on these three.
