The key issues are infective endocarditis risk, managing anticoagulant medication, and ensuring appointments are safe for you. This guide explains current UK guidance and the questions to ask before treatment starts.

These include the risk of bacteraemia triggering infective endocarditis in patients with structural heart defects, the management of anticoagulant and antiplatelet medications during treatment, the possibility that stress or lengthy appointments may be poorly tolerated, and the need to liaise with treating cardiologists before proceeding. Orthodontists are not expected to diagnose or manage cardiac conditions, but they must take a thorough medical history, identify relevant risk factors, and modify their care accordingly. Failing to do so can have serious clinical consequences. ## Infective endocarditis risk and NICE NG208 guidance Infective endocarditis (IE) is a serious infection of the heart valves or inner lining of the heart, most commonly caused by Streptococcal or Staphylococcal bacteria entering the bloodstream. Historically, dental and orthodontic procedures — which can cause transient bacteraemia — were considered a risk trigger for IE in susceptible patients. High-risk patients include those with prosthetic heart valves, a previous episode of IE, congenital heart disease with unrepaired cyanotic defects or residual defects adjacent to prosthetic material, and cardiac transplant recipients with valve regurgitation. NICE guideline NG208 (updated 2023) continues the position that antibiotic prophylaxis before dental or orthodontic procedures is not routinely recommended, even for high-risk patients, as the overall evidence does not support its effectiveness in preventing IE from dental bacteraemia. ## Antibiotic prophylaxis — current UK guidance NICE NG208 explicitly states that antibiotic prophylaxis should not be offered solely to prevent IE before invasive dental or orthodontic procedures. This guidance overturns the previous practice of giving amoxicillin or clindamycin before procedures such as banding, bonding, extractions, and debonding in high-risk patients. UK orthodontists and dentists are expected to follow this guidance. Some cardiologists — particularly those trained or practising outside the UK — may still recommend prophylaxis based on AHA (American Heart Association) guidelines. If your cardiologist has advised prophylaxis, discuss this discrepancy with your orthodontist and GP; a joint decision documented in your records is the safest approach. Regardless of prophylaxis, maintaining excellent oral hygiene throughout orthodontic treatment remains the most important protective measure. ## Anticoagulants (warfarin and NOACs) and INR monitoring Patients on anticoagulant therapy — warfarin, apixaban, rivaroxaban, dabigatran, or edoxaban — require special consideration for procedures that may cause bleeding, including extractions for orthodontic treatment and surgical placement of TADs. For warfarin, the INR should be checked within 72 hours of any surgical procedure; orthodontic treatment should proceed if INR is 2.0 to 4.0 without dose alteration. Stopping warfarin is rarely necessary and potentially dangerous. NOACs (novel oral anticoagulants) do not require routine INR monitoring but their short half-life means missing doses affects anticoagulation rapidly. Orthodontic bonding, wire changes, and retainer fitting do not typically cause significant bleeding and do not require anticoagulation adjustment. Any procedure likely to cause bleeding should be planned in liaison with the prescribing clinician. ## Pacemakers and orthodontic electrical equipment Patients with pacemakers or implantable cardioverter-defibrillators (ICDs) sometimes ask whether orthodontic equipment can interfere with their device. Standard orthodontic equipment — intraoral scanners, dental X-ray units, standard dental chairs, light-curing units, and ultrasonic scalers — does not produce electromagnetic interference at levels capable of disrupting modern pacemakers or ICDs. Electrosurgery (diathermy) and TENS devices are the main contraindications for pacemaker patients, and these are not routinely used in orthodontics. If you have a pacemaker or ICD, inform your orthodontist, but this should not prevent orthodontic treatment proceeding normally. ## Post-cardiac surgery timing Patients who have recently undergone cardiac surgery — including valve replacement, coronary artery bypass grafting, or device implantation — should complete an adequate recovery period before starting elective orthodontic treatment. The recommended minimum interval is typically 3 to 6 months post-surgery, depending on the procedure. During this period the patient is at highest risk of complications, immunosuppression from medications may affect tooth movement and healing, and the patient's focus should be on cardiac recovery. Your cardiologist should confirm fitness for elective dental treatment before you proceed. For children with congenital heart disease, the timing of orthodontic treatment should be co-ordinated with the paediatric cardiologist. ## Arrhythmia and stress management at appointments Patients with arrhythmias — including atrial fibrillation, supraventricular tachycardia, or ventricular arrhythmias — may find that anxiety and stress during appointments can trigger episodes. Orthodontists can mitigate this by scheduling shorter appointments, ensuring effective local anaesthesia where needed to reduce pain-related stress, and allowing rest periods during longer procedures. Patients should inform the orthodontist if they feel unwell during an appointment; treatment should be paused and the patient allowed to recover. If a patient loses consciousness or experiences chest pain during an appointment, standard medical emergency protocols apply and emergency services should be called immediately. ## Communication between cardiologist and orthodontist Effective care for patients with significant cardiac conditions requires communication between the treating orthodontist and the patient's cardiologist or GP. Before treatment starts, the orthodontist should send a letter outlining the planned treatment, any procedures likely to cause bleeding, and asking for confirmation of any specific precautions required. This creates a documented record and ensures that the patient's cardiac team is aware of the proposed treatment. Patients can facilitate this by bringing their cardiac diagnosis details, current medication list, and any letters from their cardiologist to the first orthodontic consultation. Where a patient has a rare or complex congenital heart condition, referral to a specialist dental unit within a hospital setting may be the most appropriate pathway. ## NHS vs private access for cardiac patients Cardiac patients who are under 18 and have IOTN grade 4 or 5 are entitled to NHS orthodontic treatment and should be assessed on the same basis as other patients. Complex medical needs do not themselves grant additional NHS priority, but they may influence where treatment is delivered — patients with severe or unstable cardiac conditions may be better treated in a hospital orthodontic department with immediate medical backup. Adult cardiac patients pursuing orthodontic treatment will typically do so privately. Costs should include any additional liaison appointments or investigation costs. Ask whether the practice has experience managing medically complex patients and whether they have emergency protocols in place. ## Useful related pages [Orthodontics and Blood Thinners](https://virtualconsultant.online/guides/orthodontics-blood-thinners-anticoagulants-uk) [Medication Effects on Orthodontic Treatment](https://virtualconsultant.online/guides/medication-effects-orthodontic-treatment-uk) [Autoimmune Disease and Orthodontics](https://virtualconsultant.online/guides/autoimmune-disease-orthodontics-uk) [Orthodontics and Diabetes UK](https://virtualconsultant.online/guides/orthodontics-and-diabetes-uk) [Immunosuppressed Patients and Orthodontics](https://virtualconsultant.online/guides/immunosuppressed-orthodontics-uk) This guide is for general information only.

Under current NICE NG208 guidance, antibiotic prophylaxis is not routinely recommended before orthodontic or dental procedures, even for patients with high-risk cardiac conditions such as prosthetic valves or previous infective endocarditis. However, if your cardiologist has specifically recommended prophylaxis, discuss this with your orthodontist so a joint decision can be documented. The most important protection is maintaining excellent oral hygiene throughout treatment. Can I have braces if I take warfarin? Yes, in most cases. Routine orthodontic procedures such as bonding brackets, wire changes, and retainer fitting do not cause significant bleeding. Procedures that do cause bleeding — such as tooth extractions for orthodontic treatment or TAD placement — require an INR check within 72 hours beforehand. If the INR is within the therapeutic range (2.0 to 4.0), treatment can proceed without altering your warfarin dose. Stopping warfarin is not recommended without medical advice. Will my pacemaker be affected by orthodontic equipment? Standard orthodontic equipment does not interfere with modern pacemakers or ICDs. Intraoral scanners, dental X-ray units, bonding lights, and ultrasonic scalers are all safe to use. Electrosurgery (diathermy) is the main electrical contraindication for pacemaker patients, and this is not used in routine orthodontic treatment. Inform your orthodontist about your pacemaker so it is documented, but it should not prevent your treatment proceeding normally. How soon after open heart surgery can I start orthodontics? Most guidelines recommend waiting at least 3 to 6 months after cardiac surgery before starting elective orthodontic treatment. Your cardiologist should confirm that you are fit for elective dental procedures before treatment begins. If you are taking post-operative anticoagulants or immunosuppressants, these need to be stable and at therapeutic levels. Starting orthodontic treatment during cardiac recovery would not be recommended. Should I tell my orthodontist about my heart condition? Yes, absolutely. You should disclose your full medical history — including all cardiac diagnoses, medications, previous procedures, and the name of your cardiologist — at your first consultation. This allows your orthodontist to plan treatment safely, identify any procedures that need modification, and liaise with your cardiac team if required. Withholding medical information could compromise your safety during treatment. Can children with congenital heart disease have orthodontic treatment? Yes, in most cases. Children with congenital heart disease (CHD) can receive orthodontic treatment, but it should be planned in close liaison with their paediatric cardiologist. The timing relative to cardiac surgery, any medication effects on bone and tooth movement, and the risk category for infective endocarditis must all be assessed. Children with complex or unstable CHD may be better treated within a hospital dental department with direct cardiac backup rather than in a standard orthodontic practice.
