Anticoagulants and Antiplatelet Drugs in Dentistry: UK Guidance for Safe Dental Practice (SDCEP & NICE)

A Complete 2026 Guide for UK Dental Professionals

As a UK dental professional, managing patients who take anticoagulant or antiplatelet medication is no longer occasional — it is routine.

From atrial fibrillation and stroke prevention to coronary stents and venous thromboembolism, modern medical care means more patients than ever are prescribed:

  • Direct Oral Anticoagulants (DOACs)

  • Warfarin

  • Aspirin

  • Clopidogrel

  • Dual antiplatelet therapy (DAPT)

Yet despite clear national guidance from SDCEP and NICE, many dental teams still ask:

  • Should I stop apixaban before an extraction?

  • What INR is safe for dental treatment?

  • Can I treat a patient on dual antiplatelet therapy?

  • Am I at medico-legal risk if I proceed?

At First Medical Training, we regularly meet dentists, therapists, hygienists, and practice managers who feel uncertain about managing bleeding risk safely and confidently.

This comprehensive guide provides:

  • Current SDCEP recommendations (2nd Edition)

  • Relevant NICE guidance

  • Practical risk assessment advice

  • Clear answers to common UK search queries

  • Medico-legal considerations

  • Best practice documentation guidance

If you work in UK dentistry, this is essential knowledge.

Why Anticoagulants and Antiplatelet Drugs Matter in UK Dentistry

The number of patients taking blood-thinning medication continues to rise due to:

  • An ageing population

  • Increased survival following cardiac events

  • Wider prescribing of DOACs

  • Improved stroke prevention strategies

These drugs are prescribed for:

  • Atrial fibrillation (AF)

  • Deep vein thrombosis (DVT)

  • Pulmonary embolism (PE)

  • Mechanical heart valves

  • Stroke prevention

  • Coronary artery stent placement

  • Acute coronary syndromes

Dental treatment is not contraindicated — but it requires structured clinical decision-making.

Incorrect management can lead to:

  • Prolonged post-operative bleeding

  • Delayed haemorrhage (6–24 hours later)

  • Emergency hospital admission

  • Thromboembolic events if medication is stopped

  • Stroke or myocardial infarction

  • GDC investigation for failure to follow national guidance

Understanding the balance between bleeding risk and thrombotic risk is critical.

Key UK Guidance for Dental Professionals

The primary reference document in the UK is:

SDCEP – Management of Dental Patients Taking Anticoagulants or Antiplatelet Drugs (2nd Edition)

This guidance is widely accepted as the gold standard for primary dental care.

Additional relevant guidance includes:

  • NICE CG180 – Atrial Fibrillation

  • NICE NG196 – Acute Coronary Syndromes

  • GDC – Standards for the Dental Team

Following SDCEP provides strong medico-legal protection, as it represents recognised national best practice.

Direct Oral Anticoagulants (DOACs) in Dental Practice

Common DOACs Prescribed in the UK

  • Apixaban (Eliquis)

  • Rivaroxaban (Xarelto)

  • Edoxaban

  • Dabigatran

DOACs are now prescribed more frequently than warfarin for many indications.

Unlike warfarin:

  • They do not require routine INR monitoring

  • They have predictable pharmacokinetics

  • They have shorter half-lives

This has important implications for dental treatment planning.

SDCEP Guidance: Managing DOACs for Dental Procedures

Low-Risk Dental Procedures

Examples:

  • Simple extraction (1–3 teeth)

  • Supragingival scaling

  • Simple restorative treatment

  • Incision and drainage

SDCEP Recommendations

✔ Do not interrupt DOAC therapy
✔ Treat early in the day
✔ Consider timing procedure just before next dose
✔ Use local haemostatic measures
✔ Provide clear post-operative advice

There is no recommendation to routinely stop apixaban, rivaroxaban, edoxaban, or dabigatran for low-risk dental procedures.

Higher-Risk Dental Procedures

Examples:

  • Surgical extraction

  • Multiple adjacent extractions

  • Flap raising

  • Periodontal surgery

  • Implant placement

For higher bleeding risk procedures, SDCEP advises:

  • Consider omitting or delaying the morning dose (depending on drug and dosing schedule)

  • Follow drug-specific recommendations

  • Seek medical advice only if:

    • Complex comorbidities exist

    • Renal impairment is present

    • Combined anticoagulant + antiplatelet therapy is prescribed

Routine GP referral is not required for straightforward cases.

What Happens If You Stop a DOAC?

This is where clinical risk becomes significant.

According to NICE CG180 (Atrial Fibrillation):

Interrupting anticoagulation increases stroke risk.

Potential consequences include:

  • Ischaemic stroke

  • Pulmonary embolism

  • Systemic embolism

  • Death

The thrombotic risk of stopping DOACs unnecessarily is often greater than the bleeding risk from dental procedures.

This is a key medico-legal principle.

Warfarin in Dental Practice

Although DOAC prescribing is increasing, many patients remain on warfarin.

Warfarin management differs because anticoagulation intensity varies.

INR Requirements for Dental Treatment

SDCEP guidance states:

  • INR must be checked within 24–72 hours before dental treatment

  • Dental treatment can proceed if INR ≤ 4.0

  • Do not routinely discontinue warfarin

If INR is above 4.0, defer treatment and refer back to anticoagulation clinic.

Common UK Search Question:

What INR is safe for dental extraction?

Answer:
Dental treatment is generally considered safe if INR is ≤ 4.0, provided local haemostatic measures are used.

Risks Associated with Warfarin in Dentistry

Possible complications include:

  • Prolonged intra-operative bleeding

  • Post-operative haemorrhage

  • Haematoma formation

  • Rare bleeding after inferior alveolar nerve block

However, stopping warfarin increases risk of:

  • Stroke

  • Valve thrombosis (in mechanical valve patients)

  • Myocardial infarction

National guidance strongly favours continuing therapy.

Antiplatelet Drugs in UK Dental Practice

Antiplatelet therapy affects platelet aggregation rather than coagulation cascade factors.

Bleeding risk is typically manageable with local measures.

Common Antiplatelet Drugs

  • Aspirin 75mg daily

  • Clopidogrel

  • Ticagrelor

  • Prasugrel

Patients may be on:

  • Single antiplatelet therapy

  • Dual antiplatelet therapy (DAPT)

Aspirin and Dental Treatment

Low-dose aspirin is extremely common in the UK.

SDCEP Recommendation

✔ Continue aspirin
✔ Do not discontinue for routine dental procedures

Stopping aspirin increases cardiovascular risk and is not justified for routine dentistry.

Bleeding is usually mild and controllable.

Clopidogrel and Ticagrelor

Often prescribed following:

  • Coronary stent placement

  • Acute coronary syndrome

  • Stroke

Dual Antiplatelet Therapy (DAPT)

DAPT commonly includes:

  • Aspirin + Clopidogrel

  • Aspirin + Ticagrelor

Premature discontinuation can cause:

  • Stent thrombosis

  • Myocardial infarction

  • Sudden cardiac death

NICE NG196 emphasises uninterrupted therapy following stent placement.

Common UK Search Question:

Can a patient on dual antiplatelet therapy have a tooth extracted?

Answer:
Yes. According to SDCEP, do not discontinue single or dual antiplatelet therapy for routine dental procedures. Manage bleeding locally.

Local Haemostatic Measures Every UK Dental Practice Should Have

Effective local haemostasis is essential.

Recommended materials include:

  • Oxidised cellulose (e.g., Surgical)

  • Collagen sponges

  • Sutures

  • Haemostatic packs

  • Tranexamic acid mouthwash (where locally available)

Clinical Technique Recommendations

  • Use atraumatic extraction technique

  • Limit number of extractions where appropriate

  • Ensure primary closure where possible

  • Apply pressure packs for adequate time

  • Treat early in the day

  • Provide written instructions

Managing Post-Operative Bleeding

Patients should be advised:

  • Bite firmly on gauze for 20–30 minutes

  • Avoid rinsing vigorously for 24 hours

  • Avoid alcohol

  • Avoid strenuous exercise

  • Contact practice if bleeding persists

Clear emergency contact details must be provided.

Red Flag Patients Requiring Enhanced Risk Assessment

Exercise additional caution in patients with:

  • Renal impairment (affects DOAC clearance)

  • Liver disease

  • Previous severe bleeding episodes

  • Combined anticoagulant + antiplatelet therapy

  • Alcohol misuse

  • Poor compliance

  • Frailty

These patients may require modified planning or liaison with medical teams.

Medico-Legal Protection for UK Dental Professionals

Failure to follow national guidance is difficult to defend in a GDC investigation.

To protect yourself:

Document clearly:

  • Medication name and indication

  • Last dose taken

  • INR result (if warfarin)

  • Risk assessment

  • SDCEP guidance followed

  • Haemostatic measures used

  • Post-operative instructions given

  • Advice sought

The GDC expects evidence-based decision making.

Following SDCEP demonstrates that your actions align with accepted UK standards.

Frequently Asked Questions

Can you extract a tooth on apixaban in the UK?

Yes. According to SDCEP guidance, most simple extractions can proceed without stopping apixaban, using appropriate local haemostasis.

Should warfarin be stopped before dental treatment?

No. Warfarin should not be routinely discontinued. Treatment is acceptable if INR ≤ 4.0.

Is it safe to do scaling on a patient taking rivaroxaban?

Yes. For low-risk procedures such as scaling, DOAC therapy should not be interrupted.

What is the biggest risk — bleeding or stroke?

In most cases, thrombotic risk from stopping anticoagulation is greater than manageable dental bleeding.

Can dental local anaesthetic blocks be given to patients on anticoagulants?

Yes. With appropriate care and aspiration technique, local anaesthetic blocks are generally safe. Monitor for haematoma formation.

Clinical Bottom Line for UK Dental Teams

✔ Do not routinely stop anticoagulants
✔ Do not routinely stop antiplatelets
✔ Check INR for warfarin patients
✔ Follow SDCEP guidance
✔ Use local haemostasis
✔ Document thoroughly
✔ Understand thrombotic risk often outweighs bleeding risk
