Success depends on planning around fatigue, heat sensitivity, trigeminal neuralgia." updated: 2026-09-05T00:00:00Z publisher: Virtual Consultant Online --- Multiple Sclerosis Neurological Conditions Special Needs Orthodontics # Multiple Sclerosis and Orthodontic Treatment Multiple sclerosis (MS) is a chronic neurological condition affecting approximately 130,000 people in the UK — one of the highest rates in the world. MS affects the central nervous system, causing a wide range of symptoms that can fluctuate, relapse, and progress over time. For patients considering or undergoing orthodontic treatment, MS creates specific challenges that benefit from informed clinical planning and open communication with the treating team.

It can be severe, unpredictable, and disproportionate to activity level. Orthodontic appointments are typically brief, but for MS patients even a short trip from home plus the physical and cognitive demands of an appointment can trigger profound fatigue. Morning appointments — before fatigue accumulates through the day — are generally better tolerated than afternoon ones. Appointments should be kept as short as possible, and patients should be allowed to rest in the waiting room before and after. Heat sensitivity (Uhthoff's phenomenon) affects the majority of MS patients: exposure to warmth temporarily worsens neurological symptoms including weakness, visual disturbance, and balance. The orthodontic clinic environment should be kept comfortably cool. Heat-generating procedures — dental light exposure, prolonged bracket bonding with heat from curing lights — should be managed with short bursts and breaks where needed. ## Trigeminal neuralgia and facial pain in MS Trigeminal neuralgia — severe, lancinating facial pain triggered by touch, eating, or cold — occurs in around 2–5% of MS patients and is more common in MS than in the general population because MS plaques can affect the trigeminal nerve root entry zone. This creates a diagnostic challenge during orthodontic treatment: lancinating or severe facial pain in an MS patient may be trigeminal neuralgia rather than orthodontic pain, periodontal disease, or toothache. MS patients should be specifically asked about facial pain patterns before starting treatment, and any new severe facial pain during treatment should be assessed carefully. Orthodontic adjustment schedules may need to be modified if trigeminal neuralgia is active. Medical management of trigeminal neuralgia — carbamazepine, oxcarbazepine, or gabapentin — does not contraindicate orthodontic treatment but should be noted in records. ## Sensory changes and their effect on orthodontic assessments Many MS patients experience paraesthesia — altered or reduced sensation — in the face, mouth, or tongue. This can affect bite registration accuracy: a patient with reduced oral sensation may not correctly perceive their bite position, leading to inaccurate clinical records. Orthodontists should take extra care with bite registrations and may need to perform them more slowly, with the patient guided to maximum intercuspation manually. Sensory changes can also alter pain perception during treatment — some MS patients report less orthodontic soreness than expected, while others report heightened sensitivity. Communicating openly about symptom changes after adjustments helps both patient and clinician calibrate responses appropriately. ## Disease-modifying therapy and effects on bone Modern MS treatment centres on disease-modifying therapies (DMTs) that reduce relapse frequency and slow progression. Natalizumab (Tysabri), ocrelizumab (Ocrevus), alemtuzumab (Lemtrada), and other DMTs work primarily on the immune system and their direct effects on bone metabolism are limited. Published data on the orthodontic implications of specific DMTs is sparse. Fingolimod (Gilenya) — an oral sphingosine-1-phosphate receptor modulator — has been associated with a small number of case reports of gingival enlargement, which is relevant to orthodontic treatment because gingival overgrowth impedes tooth movement and makes hygiene harder. Orthodontists managing patients on fingolimod should monitor gingival health closely throughout treatment. For most other DMTs, no specific orthodontic precautions are currently recommended beyond standard practice. ## Corticosteroid use during MS relapses Relapses in MS are commonly treated with high-dose intravenous methylprednisolone (typically 500 mg to 1 g per day for three to five days). Repeated courses of corticosteroids are associated with reduced bone mineral density — a relevant consideration for orthodontic treatment because adequate alveolar bone density is required for predictable tooth movement and anchorage. Patients who have received frequent corticosteroid courses for MS relapses may warrant discussion of bone health with their neurologist. Long-term oral corticosteroids for any reason should also be noted and may indicate the need for a more conservative approach to force levels and extraction decision-making. Calcium and vitamin D supplementation is commonly prescribed to corticosteroid-treated MS patients, which has a modest beneficial effect on bone density. ## Aligner compliance with hand dexterity difficulties Clear aligner treatment requires the patient to remove and re-insert their aligners multiple times per day. This demands reasonable hand strength and fine motor control — something that is impaired in MS patients with upper limb weakness, tremor, or spasticity. Patients with moderate or severe hand dexterity impairment may genuinely struggle to remove tight-fitting aligners without assistance, and forgetting or avoiding removal for eating and drinking leads to poor compliance. Aligner removal tools are available — small plastic hooks designed to assist tray removal — and these can be invaluable for patients with grip or dexterity difficulties. Fixed braces avoid the compliance issue entirely and may be the more appropriate appliance choice for patients with significant upper limb involvement. The treating orthodontist should assess dexterity realistically at the treatment planning stage and discuss appliance options openly. ## Relapse timing and orthodontic procedure planning MS relapses — periods of new or worsening symptoms — are not predictable but are more likely during periods of stress, infection, or post-partum. Major orthodontic procedures — brace bonding, surgical exposure of impacted teeth, or orthognathic surgery — should be timed away from active relapses wherever possible. During a relapse, the patient's capacity to attend appointments and manage appliance care is reduced. Orthodontists should adopt a flexible scheduling approach for MS patients and have a clear plan for treatment pauses when needed. Communication with the MS nurse specialist — who is the day-to-day clinical contact for most UK MS patients — can help coordinate timing of orthodontic milestones around the patient's neurological management. ## UK resources and liaison with the MS care team The MS Society (mssociety.org.uk) provides information on dental care with MS, including guidance on accessing treatment adjustments and reasonable adjustments under the Equality Act 2010. The MS Trust similarly offers patient-facing resources. Most MS patients in the UK are managed by a neurologist, an MS nurse specialist, and often physiotherapy and occupational therapy. The MS nurse specialist is the most accessible contact for orthodontists wishing to discuss treatment timing, relapse frequency, DMT implications, or functional capacity. A brief introductory letter from the orthodontist to the MS nurse — with the patient's consent — at the start of a treatment course sets a useful foundation for communication during what may be a multi-year treatment period. ## Useful related pages [Fibromyalgia and Orthodontics](https://virtualconsultant.online/guides/fibromyalgia-orthodontics-uk) [Medication Effects on Orthodontics](https://virtualconsultant.online/guides/medication-effects-orthodontic-treatment-uk) [Dental Anxiety and Orthodontics](https://virtualconsultant.online/guides/dental-anxiety-orthodontics-uk) [Orthodontic Appointment Frequency](https://virtualconsultant.online/guides/orthodontic-appointment-frequency-uk) [Orthodontics for Special Needs UK](https://virtualconsultant.online/guides/orthodontics-special-needs-uk) This guide is for general information only.

MS does not preclude orthodontic treatment, and many MS patients complete successful courses of braces or clear aligners. The key is planning that accounts for fatigue, heat sensitivity, appointment scheduling, appliance choice, and the potential impact of relapses or DMT side effects. Discussing your MS openly with your orthodontist at the consultation stage allows for a treatment plan tailored to your needs. Should I choose clear aligners or fixed braces if I have MS? This depends on your specific symptoms. Clear aligners require good hand dexterity to remove and insert trays multiple times daily — if you have upper limb tremor, weakness, or spasticity, fixed braces may be more practical. Fixed braces require no compliance with wear time and do not need to be removed. However, they demand more rigorous hygiene, which can be challenging if oral care is affected by fatigue or reduced fine motor control. Discuss both options with your orthodontist in the context of your particular MS symptoms. Can MS cause toothache or facial pain that mimics orthodontic pain? Yes. Trigeminal neuralgia — severe, electric shock-like facial pain — is more common in MS than in the general population because MS lesions can affect the trigeminal nerve. This can be confused with orthodontic pain, dental pain, or temporomandibular joint pain. If you have known MS and experience new severe lancinating facial pain during orthodontic treatment, tell your orthodontist and your neurologist or MS nurse so that an appropriate assessment can be made. Does Roaccutane affect MS patients who need orthodontics? Isotretinoin (Roaccutane) is not a treatment for MS. If an MS patient also has severe acne requiring isotretinoin, the considerations about isotretinoin and orthodontics apply alongside the MS-specific considerations — these would need to be managed together with input from both the prescribing dermatologist and the neurologist. Will MS relapses delay my orthodontic treatment? They may. During an active relapse, attending appointments may be difficult and appliance management may be compromised. Most orthodontists will adopt a flexible approach for MS patients, allowing pauses in active treatment during relapses and resuming when the patient has recovered. Minor delays of weeks to months are unlikely to harm the overall treatment outcome. Communicating promptly with your orthodontist when a relapse occurs helps avoid unnecessary missed appointments and allows the treatment plan to be adjusted. Do MS medications affect orthodontic tooth movement? Most DMTs used for MS do not have well-documented direct effects on orthodontic tooth movement. Fingolimod has been linked to gingival enlargement in some patients, which can complicate tooth movement and hygiene. Repeated high-dose corticosteroids for relapses may affect bone mineral density over time. For most MS patients on standard DMTs, no specific modification to orthodontic mechanics is required, but your orthodontist should be aware of all medications you are taking. What reasonable adjustments should I ask for at an orthodontic practice for MS? Under the Equality Act 2010, dental practices are required to make reasonable adjustments for disabled patients. For MS, these might include morning appointment preference, a cool waiting and treatment environment, a reclining or adjustable chair to manage fatigue and balance, extended appointment time if needed, a carer being present, and flexible rescheduling when relapses occur. Do not hesitate to communicate your needs to the practice — most orthodontists are happy to accommodate adjustments that make treatment more accessible.
