If you take or have taken medication for osteoporosis, your dentist needs to know before any surgery in the jaw — including extractions and dental implants. This is one of the few medical details where an omission can genuinely change an outcome, and it is often left out because patients do not connect a bone tablet with their teeth.
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 medication history in detail at consultation for this reason.
Which medications matter?
The group of interest are drugs that alter bone turnover. They include:
- Bisphosphonates, taken as tablets (weekly or monthly) or given by infusion.
- Denosumab, given as an injection, commonly six-monthly.
- Some other bone-modifying agents used in cancer care.
They are prescribed for osteoporosis, and at higher doses in the management of certain cancers that affect bone.
Corticosteroids taken long term are also worth mentioning, as are treatments for rheumatoid arthritis and some cancer therapies, all of which can influence healing.
Why do they affect the jaw?
These medications work by slowing the cells that break down bone. That is the point — it preserves bone density and reduces fracture risk.
The jaw, however, remodels more actively than most bones and is unusual in being separated from a bacteria-rich environment by only a thin layer of tissue. When bone turnover is suppressed and the bone is then exposed by surgery, healing can be slower and in some cases the bone does not cover over as expected.
The condition that can result is called medication-related osteonecrosis of the jaw, usually abbreviated MRONJ: an area of jawbone that stays exposed and does not heal. It is uncommon, particularly at the doses used for osteoporosis, and considerably more likely at the higher doses used in oncology. But it is serious when it occurs, and prevention is far easier than treatment.
Does this mean I cannot have implants?
Not usually. For most people taking oral bisphosphonates for osteoporosis, the reported risk is low, and implant treatment is often proceeded with after discussion.
What changes is the process:
A fuller history is taken — which drug, what dose, how it is administered, how long you have taken it, and whether you have stopped.
Your prescribing doctor may be contacted. Coordination matters, particularly where a decision about pausing medication might be raised. That decision belongs to the doctor managing your bone health, never to a dentist alone, and stopping osteoporosis medication carries its own fracture risk.
The plan may be adjusted — fewer surgical sites at once, gentler technique, closer follow-up, and attention to any infection before rather than after surgery.
You are told the risk plainly, in writing where relevant, before consenting.
In higher-risk situations — particularly intravenous bone medication given for cancer — elective implant surgery may be advised against, and alternatives such as a bridge or a removable option discussed instead.
What if I stopped taking it years ago?
Tell your dentist anyway. Bisphosphonates bind to bone and their effect persists after the last dose — for a considerable period. "I used to take it" is relevant information, not old news.
This is the single most common omission. People stop a medication, remove it from their list, and it never comes up again.
What should I bring to the consultation?
- A current, complete medication list, including anything taken by injection or infusion, and over-the-counter products and supplements.
- Any medication you have stopped in recent years, especially bone medication.
- Your prescribing doctor's details.
- Any history of jaw surgery, extractions or slow healing.
- Whether you have had radiotherapy to the head or neck, which affects jaw healing in a related way.
What can I do to lower the risk?
Prevention centres on avoiding surgery where possible and keeping the mouth healthy so surgery becomes less likely.
- Have dental problems addressed before starting bone medication, if that timing is available to you. This is worth raising with your doctor when the medication is first proposed.
- Keep gum disease under control, since infection is a contributing factor.
- Maintain regular examinations, so small problems are treated before they need extraction.
- Report any exposed bone, persistent pain, swelling or a non-healing socket promptly.
- Stop smoking if you can, since it compounds the risk — see smoking and implants.
The honest summary
For most people on osteoporosis medication, dental treatment including implants proceeds with additional care rather than being ruled out. For a smaller group, particularly those on high-dose intravenous therapy, the calculation is different.
What matters is that the decision is made with the full picture. Individual risk varies with the drug, dose, duration and your general health, and can only be assessed properly in consultation with both your dentist and the doctor managing your bone health.

Arranging an assessment
Planning includes a CBCT scan taken on site and a written, itemised quote with item numbers before anything is booked. Consultations run in English or Korean. HICAPS on-the-spot claiming is available, and the practice is a CBHS and NIB preferred provider.
