Updated 2 November 2026: This article previously mixed up contraindications with complications and described several medical conditions as absolute barriers to extraction. It has been rewritten to explain individual risk assessment and precautions.
Having a medical condition does not automatically mean a tooth can never be removed. A dentist weighs the reason for extraction, alternatives, the urgency of the problem and your health. Sometimes care can proceed with precautions; sometimes planned treatment needs medical coordination or specialist care.
What does “contraindication” mean?
A contraindication is a reason a treatment may be unsuitable in a particular situation. A complication is a problem that happens during or after treatment. Bruising or a possible difficult recovery is not, by itself, proof that extraction is impossible.
Ask your dentist: “Is this a reason to avoid extraction, a reason to adjust the plan, or a risk we need to manage?” Those are different decisions.
Blood thinners and bleeding disorders
Tell the dentist about anticoagulants, antiplatelet medicines, abnormal bleeding and any diagnosed bleeding disorder. Many dental procedures can be managed without stopping prescribed blood-thinning treatment, using measures at the extraction site to control bleeding.
Do not stop aspirin, warfarin or another prescribed blood thinner yourself. Changes, if needed, must be planned with the appropriate clinician. The medicine, procedure and your other health conditions affect the plan; some patients need tests or specialist input.
Diabetes and high blood pressure
These diagnoses do not automatically rule out extraction. Poorly controlled diabetes can affect infection risk and healing. Your team may need recent information about glucose control, medicines and food intake, particularly if eating will be difficult after treatment. Do not change diabetes medicines or skip meals without instructions.
Blood pressure may be checked at the dental visit. Markedly elevated readings, symptoms or unstable cardiovascular health can change whether treatment should proceed, be deferred or take place with additional support. A general article cannot set a single safe threshold for every patient.
Osteoporosis medicines and previous cancer treatment
Tell the dentist if you take, or previously took, bisphosphonates or denosumab, and why they were prescribed. These medicines can be associated with medication-related osteonecrosis of the jaw. Risk differs between osteoporosis and higher-dose cancer regimens, and extraction requires an individual discussion of benefits, alternatives and healing risks.
Do not stop or delay these medicines on your own. Evidence does not support a routine drug holiday for every patient taking osteoporosis antiresorptive treatment.
Previous radiotherapy involving the jaws can also affect healing, even long after cancer treatment. Your dentist may need treatment records and specialist advice before deciding on extraction or an alternative.
Pregnancy
Pregnancy alone is not a reason to leave a necessary extraction untreated. Timing, medicines and positioning should be tailored to the patient. Read the guide to dental care during pregnancy.
What about infection or difficulty opening my mouth?
An infected tooth needs assessment and treatment of the source. Depending on the diagnosis, care may include drainage, root canal treatment or extraction. Infection is not a blanket reason to wait for it to disappear before providing dental care. Significant difficulty opening the mouth or spreading swelling may require urgent or specialist assessment.
Seek emergency medical help for difficulty breathing or swallowing, or major mouth or neck swelling. Tell the service about your health conditions and medicines.
Questions to ask before agreeing to extraction
- Why is removal recommended, and could the tooth be saved?
- Which risks apply specifically to me?
- Do you need to speak to my medical team or refer me?
- What should I do about my medicines, meals and follow-up?
- Who should I contact if there is a problem afterwards?

This overview explains precautions; it cannot decide whether extraction is suitable for an individual.
A tooth that is severely damaged may need to be removed. A surgeon who specializes in surgeries of the mouth or your dentist can remove a tooth.
how cam i extract a tooth root stumps,upper right first molar,having random blood sugar count 300.and there is a severe swelling in that region,extraction is the only treatment.
@geet vijay, Extraction is not advised when the patient has a random blood sugar level count greater than 125 mg/dL, so the patient needs to be kept on medication to keep the levels low, and only then the extraction is possible. Or else there would a lot of chances of getting infections, continuous bleeding which would be hard to stop. Diabetes and sugar levels are one of the biggest contra-indications for the tooth extraction.
@dental imaging, Didn’t get you. What am trying to explain is that, removal of a tooth doesn’t always depend on the specialty of the dentist. Extraction has a few contraindications which need to be looked upon.
a patient had swelling below left lower premolar and molar region , and molar was slightly tender so access opening was done and antibiotics were given , patient came back wid samw amount of swelling after few days , and got allergy wid metronidazole. dere was no pain on filing . then patient was given oflocos-oz wid preminac sp , patient dint respond and gt allergy . then after 20 days patient came again wid soft sweeling and the pus was sucked out from same region …the amount of sweeling was same….none of the teeth was tender…nad o p g showed some well defined radiolucency much below the premolar roots near mandibular canal the same radiolucency was seen on left side widout ne symtoms . patient only complies well wid ciplox tz. patient has no pain as such still the swelling exists and sometimes pus gets sucked out n sometimes its hard . what should be done ?
can you tell me the exact blood sugar level and blood pressure level above which extraction is contraindicated??
what should be the blood sugar range advisable for extraction both fasting and p.p.?
@dr priyanka banerjee,
blood pressure diastolic shold never exceed beyond 90 mm of hg…however systolic blood pressure can be 160-180 mm of hg depending upon the age
