Most people skip the medication question on the form. It is the one dentists most want answered, because a few medicines change the plan — and stopping one of them on your own is the riskiest thing you can do before an appointment.
Every dental form asks what medication you take, and most people write "none" or skip it. It is the question dentists most want answered, because a handful of medicines genuinely change how treatment is planned — and one of them changes what you must not do before an appointment.
The one to get right first
If you take a blood thinner, do not stop it on your own before dental work.
This is the most common and most dangerous decision patients make by themselves. The reasoning feels sensible — less bleeding — but stopping an anticoagulant without supervision carries a risk of clot, stroke or heart attack that is generally considered more serious than bleeding from a dental socket, which a dentist can usually control locally.
Most extractions and most routine treatment go ahead with the medication continued. Any change is a decision for the doctor who prescribed it, in coordination with the dentist — never a unilateral one.
Tell the clinic before the appointment, not on the day. Common examples include warfarin, the newer direct oral anticoagulants, aspirin and clopidogrel.
Medicines that change the plan
| What you take | Why the dentist needs to know |
|---|---|
| Blood thinners / antiplatelets | Bleeding control and timing — never stopped without the prescriber |
| Bisphosphonates, denosumab (osteoporosis, some cancer care) | Affects how the jaw heals after extractions or implants. Say so even if you stopped years ago |
| Immunosuppressants, long-term steroids | Infection risk and healing time |
| Diabetes medication | The medication matters less than how controlled things are; relevant for surgery and implants |
| Some blood pressure medicines | A few can cause gum overgrowth that looks like gum disease but is not |
| Antidepressants, antihistamines, some others | Dry mouth, which raises decay risk over time |
This is not a list of reasons to be refused treatment. In almost every case it changes how something is done, not whether.
Conditions worth saying out loud
- Heart valve problems, a previous heart-valve infection, or a prosthetic joint. Antibiotic cover before treatment is given far more selectively than it used to be, but the decision needs the history.
- A recent heart attack or stroke, within the last several months.
- Pregnancy, including if you are trying.
- Allergies — especially to penicillin or latex. "I had a reaction once" is worth saying even if you do not know to what.
- Radiotherapy to the head or neck, at any point in the past.
When you do not share a language
This is where it usually breaks down, and the fix is not translation.
Photograph the boxes. Korean medication packaging prints the generic drug name in Latin letters alongside the Korean, and so does most packaging from elsewhere. A photo of the box communicates more accurately than any sentence either of you could construct.
If you were prescribed it in Korea, the 약 봉투 — yak bongtu, the pharmacy envelope — lists everything, and the 처방전 — cheobangjeon, the prescription — more still. Keep one and show it.
To raise it at all, this is enough:
| Korean | Roughly |
|---|---|
| 약 먹고 있어요 | yak meokgo isseoyo — I'm taking medication |
| 피 묽어지는 약이에요 | pi mulgeojineun yagieyo — it's a blood thinner |
| 알레르기 있어요 | allereugi isseoyo — I have an allergy |
What the dentist actually does with it
Mostly, planning. Treatment might be scheduled for the morning, or split into shorter visits. Local measures for bleeding are prepared in advance. An antibiotic may or may not be added. Sometimes the dentist calls your doctor before proceeding.
What rarely happens is refusal. The reason to tell them is not to be turned away — it is so that the predictable thing is planned for rather than discovered halfway through.

Frequently asked questions
Should I stop my blood thinner before a tooth extraction?
Not on your own. Stopping an anticoagulant without supervision carries a clot, stroke or heart attack risk that is generally considered more serious than bleeding from a dental socket, which a dentist can usually control locally. Most extractions go ahead with the medication continued. Any change is a decision for the doctor who prescribed it, coordinated with the dentist — tell the clinic before the appointment rather than on the day.
Which medications does a dentist need to know about?
Blood thinners and antiplatelets, bisphosphonates or denosumab for osteoporosis (even if you stopped years ago), immunosuppressants and long-term steroids, diabetes medication, some blood pressure medicines that can cause gum overgrowth, and anything causing dry mouth such as certain antidepressants and antihistamines. In almost every case it changes how something is done, not whether.
Why does an osteoporosis drug matter years after I stopped?
Bisphosphonates and denosumab affect how the jaw heals after extractions or implant surgery, and the effect can persist well after the last dose. It does not usually prevent treatment, but the dentist plans differently and may discuss it with your doctor. Mention it even if it feels like old history.
How do I tell a Korean dentist about my medication if I don't speak Korean?
Photograph the boxes. Korean packaging prints the generic drug name in Latin letters alongside the Korean, as does most packaging from elsewhere, so a photo communicates more accurately than a translated sentence. If it was prescribed in Korea, the 약 봉투 (yak bongtu, pharmacy envelope) or 처방전 (cheobangjeon, prescription) lists everything — keep one and show it.
Will a dentist refuse to treat me because of my medication?
Rarely. It usually changes the timing, the technique, what is prepared for bleeding, or whether an antibiotic is added — and occasionally the dentist calls your doctor first. The point of telling them is not to be turned away; it is so the predictable thing is planned for rather than discovered halfway through.
