Medication and Dental Treatment — What Your Dentist Needs to Know

Most dental treatment goes ahead without any complications related to medications. A few, however, change how we plan an appointment — particularly blood thinners, certain bone medications, immunosuppressants, and a small number of others. The single most useful thing you can do before your visit is bring an accurate list of what you are taking.

This page explains why medications matter, what to bring to your appointment, and how we plan treatment safely around them. To book, please book online or phone the practice during business hours.

Why your medication list matters

Medications can affect dental treatment in several ways:

Bleeding — some medications make you bleed more, which matters for extractions and gum surgery
Healing — some affect how bone and gum tissue heal afterwards
Interactions — antibiotics and certain anaesthetic medications can interact with regular medications
Side effects in the mouth — dry mouth, taste changes, gum overgrowth, or ulcers
Anaesthetic safety — particularly with cardiovascular medications
Allergies and reactions — important to flag before any injection or prescription

You do not need to know what each medication does — we just need an accurate list so we can plan safely.

What to bring or share

Please bring or send through:

A current list of all medications and doses, including new or recently changed ones
Over-the-counter products such as aspirin or fish oil
Vitamins and supplements
Herbal remedies (some affect bleeding)
Inhalers, patches, and topical medications
Any IV or infusion medications you have had — particularly bisphosphonates or denosumab
Allergies and previous reactions, including to local anaesthetic
Recent INR results if you are on warfarin

A printed list from your GP, or a screenshot from My Health Record or the Express Plus Medicare app, is perfect. If you forget — we can usually still proceed with routine care and reschedule anything more involved.

Common medications that affect dental treatment

Blood thinners and antiplatelets

Medications including:

Warfarin
Apixaban (Eliquis), rivaroxaban (Xarelto), dabigatran (Pradaxa)
Aspirin (regular daily dose)
Clopidogrel (Plavix), ticagrelor (Brilinta)

For check-ups, fillings, and most non-surgical work, no change is needed. For extractions and surgical work, we plan around the medication carefully — usually without stopping it, because the risk of stopping is often greater than the risk of bleeding. For warfarin, a recent INR is helpful. We may liaise with your GP or specialist.

Bisphosphonates and denosumab

Medications used for osteoporosis and certain cancers can affect how the jawbone heals after extractions and implant surgery. These include:

Alendronate (Fosamax), risedronate (Actonel)
Zoledronic acid (Aclasta, Zometa) — infusions
Denosumab (Prolia, Xgeva) — injections

For routine cleans and fillings these medications do not change much. For extractions or implant surgery, the picture is more individual — particularly with IV or injectable forms used for cancer. We will plan carefully and may consult with your specialist.

Immunosuppressants and biologics

Medications for autoimmune conditions, organ transplants, and inflammatory disease — including prednisone, methotrexate, azathioprine, and biologics like adalimumab (Humira), etanercept (Enbrel), and infliximab (Remicade) — can affect healing and infection risk. We work around them rather than against them and coordinate with your specialist where it makes sense.

Cardiovascular medications

Beta blockers, ACE inhibitors, calcium channel blockers, and diuretics are very common and rarely cause problems for dental treatment. Some calcium channel blockers can cause gum overgrowth — worth knowing because a good clean usually settles it.

If you have had a recent heart attack, stent, valve replacement, or major cardiac surgery, please tell us — we may stage elective treatment or coordinate with your cardiologist.

Diabetes medications

Insulin, metformin, GLP-1 medications, and SGLT2 inhibitors do not usually need adjustment for dental treatment. The main thing we plan around is avoiding hypoglycaemia during longer appointments — see our diabetes and dental health page.

Antidepressants and anti-anxiety medications

SSRIs, SNRIs, and other antidepressants generally do not cause issues. A small number affect bleeding slightly, and many can cause dry mouth. Benzodiazepines occasionally interact with sedation — please let us know if you are on any.

Asthma and COPD medications

Inhaled corticosteroids can predispose to oral thrush. Bring inhalers to longer appointments in case they are needed during the visit.

Cancer treatment

Chemotherapy, radiation to the head and neck, and certain newer targeted therapies have significant implications for dental treatment — both during and after treatment. Please flag any current or recent cancer treatment when you book, and we will plan accordingly.

Antibiotics, including bisphosphonate alternatives

If you are already on antibiotics, or have had repeated courses, tell us — particularly if there is any history of Clostridioides difficile infection or significant allergy.

Allergies — what we need to know

True allergic reactions to dental medications are uncommon but important to flag. Please mention:

Any past allergic reaction to penicillin or other antibiotics
Reactions to local anaesthetic (real anaphylaxis is rare; fainting and palpitations are much more common — both are worth noting)
Latex allergy
Allergy to metals (nickel is the most common)
Allergy to chlorhexidine or other antiseptics
Severe asthma, particularly if triggered by NSAIDs

Pregnancy and breastfeeding

If you are pregnant or breastfeeding, please tell us — it changes the medications we use and prescribe. Local anaesthetic and most common dental medications are safe in pregnancy and during breastfeeding, but a small number of antibiotics and pain medications are avoided. Our pregnancy and dental care page has more.

Antibiotic prophylaxis (premedication)

Some patients are advised to take a single dose of antibiotics before certain dental procedures — typically those with certain heart valve conditions, a history of infective endocarditis, or a recent joint replacement (in some cases). The current Australian guidelines are quite specific. We will check whether premedication applies to you and prescribe it where appropriate.

If you have just started a new medication

Please mention it. Side effects in the mouth — ulcers, dry mouth, gum changes, altered taste — are sometimes the first sign of a new medication issue, and your dentist can flag this back to your GP if needed.

What we will do at the appointment

Review your full medication list (yes, even the ones you have been on for years)
Confirm any allergies and recent medical changes
Check whether the planned treatment needs any adjustments
Discuss any need to liaise with your GP or specialist
Explain pain relief and antibiotic plans clearly
Update your records, so future visits are easier

Medication FAQs

Should I stop my blood thinner before a tooth extraction?

Usually no. For most patients we plan around the medication rather than stopping it, because the risk of stopping is often greater. Your dentist will explain what we recommend in your case.

I take Prolia for osteoporosis — does that matter for my dentist?

Yes, please mention it. For routine fillings and cleans it does not change much. For extractions or implants, we plan carefully and may coordinate with your GP.

Do I need antibiotics before every dental visit because I had a hip replacement?

For most patients, no — current guidelines have moved away from routine premedication for joint replacements. Bring details and we will check your situation.

What if I forget my medication list?

For routine appointments this is usually fine — we can update on the day. For surgical appointments we may need to reschedule if the picture is unclear.

Can dental local anaesthetic interact with my heart medication?

In most cases no, but the choice of anaesthetic may be adjusted. This is one reason to share your full list.

Why do my gums look swollen since I started a new medication?

Some medications — including certain calcium channel blockers, ciclosporin, and phenytoin — can cause gum overgrowth. A good professional clean usually helps, and we will work with your GP if needed.

I had a bad reaction to dental local anaesthetic once. Can I still have treatment?

Almost certainly yes. Most past “reactions” turn out to be fainting, palpitations from a small amount of adrenaline, or anxiety rather than allergy. Bring details and we will plan a safe alternative if needed.
