# Ehlers-Danlos Syndrome (EDS) and Orthodontic Treatment

Ehlers-Danlos syndrome encompasses a group of hereditary connective tissue disorders characterised by joint hypermobility, skin fragility, and tissue laxity. The hypermobile type (hEDS) is the most common and the most relevant to orthodontics. This guide explains how the condition affects your oral tissues, joints, and pain experience and what adaptations are needed for safe treatment.

## How does TMJ hyperlaxity in EDS affect orthodontics?

The temporomandibular joint is a synovial joint stabilised by ligaments and the joint capsule. In EDS, generalised connective tissue laxity means these stabilising structures are more extensible than normal, producing TMJ hypermobility. Patients frequently report jaw clicking, clunking, catching, and locking. Subluxation — where the condyle slides forward out of the fossa — can occur on wide opening. TMJ hypermobility creates a complex backdrop for orthodontic treatment: appliances that alter the bite, even transiently, can destabilise an already hyperlaxic joint. Patients with active TMJ subluxation or dislocation require careful joint assessment and management before or alongside orthodontics.

## How does tooth hypermobility in EDS affect tooth movement?

The periodontal ligament (PDL) is the connective tissue that suspends each tooth in its bony socket and provides the biological mechanism for orthodontic tooth movement. In EDS, the PDL may be more lax than normal, which has two implications. First, teeth may have more inherent mobility — they move more easily under normal biting forces. Second, orthodontic forces applied to hypermobile teeth may produce faster, less controlled movement, making careful force calibration essential. The same laxity may also mean teeth are more likely to relapse after treatment, returning towards their original positions when active forces are removed.

## How does tissue fragility in EDS affect orthodontic treatment?

Gingival fragility in EDS means that the gum tissue may be more susceptible to trauma from orthodontic appliance components — archwires, elastics, and bracket edges. Good appliance design with smoothed and covered components helps minimise gum trauma. Enamel defects and dentine hypersensitivity are reported by some EDS patients, though not universal. Bracket bonding may be less reliable if there is any enamel surface abnormality, and the orthodontist should check bond strength carefully. Medical-grade adhesive tapes used in some orthodontic procedures can cause skin reactions or bruising in EDS patients with skin fragility.

## Why should orthodontic forces be lighter for EDS patients?

Standard orthodontic force levels are calibrated for typical connective tissue. In EDS, reduced forces are appropriate for two reasons: tissue fragility means excessive forces risk causing more harm than in a typical patient, and tooth movement may occur faster than expected due to PDL laxity, risking uncontrolled overmovement. Most EDS-experienced orthodontists use lighter initial archwires, progress through wire sequences more slowly, and use reduced force spring designs to maintain control throughout treatment.

## Should EDS patients choose clear aligners or fixed braces?

Clear aligners have some practical advantages for EDS patients. They are removable, avoiding the continuous mucosal trauma that fixed appliances can cause in patients with fragile gum tissue. They cause less friction on soft tissues. They can be removed if TMJ symptoms flare. Fixed braces offer continuous controlled forces and are appropriate for complex tooth movements. The decision should be made in discussion with the orthodontist considering each individual's joint status, tissue fragility, and pain profile — both approaches can work well for EDS patients with appropriate modifications.

## How should patients with EDS be managed at orthodontic appointments?

Central sensitisation and widespread pain are features of hEDS, and many EDS patients report heightened sensitivity to procedures that non-EDS patients find minimally uncomfortable. Practical accommodations include: longer appointment slots to allow more rest breaks, topical anaesthesia before bracket bonding, careful communication with the patient during each step, willingness to pause and reschedule if pain is excessive, and avoidance of heavy initial forces. Premedication with appropriate analgesics, coordinated with the patient's GP or pain management team, may help for particularly demanding procedures.

## Why is long-term retention especially important in EDS?

Relapse risk after orthodontic treatment is higher in EDS patients than in the general population due to the inherent laxity of the PDL and surrounding soft tissues. Standard retention protocols may need to be extended to full-time or near-full-time wear indefinitely. Patients with EDS should be counselled at the outset that lifelong retention is likely to be necessary. Some specialists advocate for bonded retainers on both arches and may recommend more rigid removable retainer designs. If a retainer is lost or broken, prompt replacement is especially important in EDS patients to prevent rapid relapse.

### Frequently Asked Questions

Can I have orthodontic treatment if I have Ehlers-Danlos syndrome?

Yes. EDS is not a contraindication to orthodontic treatment, but it requires an experienced orthodontist who is aware of the condition and willing to adapt their approach. Key modifications include reduced forces, attention to tissue fragility, careful TMJ assessment, pain-sensitive appointment management, and a robust long-term retention plan. Many EDS patients complete orthodontic treatment successfully with these adaptations in place.

Will braces worsen my TMJ problems if I have EDS?

There is a risk that orthodontic appliances, particularly those that alter the bite position, may aggravate a hyperlaxic TMJ. A thorough joint assessment before starting treatment helps identify the current level of instability. If TMJ subluxation is frequent or disabling, this should be addressed or at least stabilised before orthodontic treatment begins. Many EDS patients with mild to moderate TMJ symptoms complete orthodontic treatment without worsening joint problems when care is taken with appliance selection and force levels.

Are clear aligners better than fixed braces for EDS patients?

Many EDS patients find clear aligners more tolerable because they avoid continuous soft tissue contact and can be removed during symptom flares. However, they require sustained compliance and may not suit all cases orthodontically. Fixed braces provide continuous controlled forces and are appropriate for complex tooth movements. The choice depends on individual factors and should be made with your orthodontist after a thorough assessment of your joint status, tissue fragility, and pain profile.

Why do I need lighter orthodontic forces if I have EDS?

The periodontal ligament in EDS may be more lax, meaning teeth may respond to orthodontic forces more readily and less predictably than expected. Lighter forces reduce the risk of uncontrolled overmovement and root resorption. They also reduce discomfort at appointments, which is important given the pain sensitivity that many EDS patients experience. Your orthodontist can adjust wire sequences and spring designs to apply appropriately reduced force levels throughout treatment.

How long will I need to wear retainers after braces if I have EDS?

Lifelong retention is the realistic expectation for most EDS patients. The inherent laxity of the connective tissues means teeth are more likely to drift back towards their original positions when active treatment ends. A combination of fixed bonded retainers and removable retainers worn nightly indefinitely is typically recommended. Patients should be counselled about this at the start of treatment so that the commitment to lifelong retention is understood before proceeding.

Do I need to tell my orthodontist I have EDS?

Yes, absolutely. Informing your orthodontist about your EDS diagnosis — and any medications you take for it, including pain management — allows them to plan appropriate treatment. It also ensures the team know to handle tissue gently, avoid adhesives on fragile skin, and accommodate your pain sensitivity at appointments. EDS is not widely known in general dental practice, so bringing information about your specific subtype and current symptoms is very helpful for the treating team.

Is root resorption more likely in EDS patients during orthodontic treatment?

There is limited specific research on root resorption rates in EDS. However, given that PDL laxity may affect the biomechanics of tooth movement, and that lighter forces are used which generally reduce resorption risk, many orthodontists are cautiously optimistic about the risk profile. Standard monitoring protocols — including periapical radiographs at six months of treatment — should still be followed. Inform your orthodontist of any family history of significant root resorption, as this is an additional risk factor to consider.
