Crossbite Treatment UK

Yes, in most cases. Dental crossbites — where individual tooth positions are responsible — can be corrected with braces or aligners at any age. Skeletal crossbites in adults involve the jaw width itself, and while dental compensation is possible, severe cases may need surgically assisted palatal expansion for a stable result. Your orthodontist will assess which type you have and recommend the appropriate approach.

Not all crossbites require urgent treatment, but any crossbite should be assessed because some affect jaw function, gum health, or tooth wear over time. Functional crossbites that shift the lower jaw are particularly worth treating early in children, as the asymmetric jaw position can influence how the face and jaw develop during growth.

Clear aligners can be effective for dental crossbites, especially mild to moderate anterior or posterior tooth-position problems. They are less reliable for significant expansion of the upper jaw or for crossbites involving a large skeletal component. The treating orthodontist should review whether aligners alone or aligners combined with elastics can achieve the planned correction.

Treatment duration varies with the type and severity of crossbite. A single-tooth anterior crossbite in a child may be resolved in a few months with a simple removable appliance. A posterior crossbite requiring expansion and full fixed braces typically takes 18 to 24 months. More complex skeletal crossbites or those treated surgically take longer and require multi-disciplinary planning.

Yes. Crossbites that score IOTN grade 4 or 5 on the dental health component — particularly those with a functional jaw shift or causing damage to teeth or gums — qualify for NHS orthodontic treatment for patients under 18. Your general dental practitioner can complete an IOTN assessment and refer if the threshold is met.

Relapse risk depends on the type of crossbite and the retention plan. Dental crossbites corrected with braces rarely relapse if retainers are worn consistently. Crossbites involving upper arch expansion have a higher relapse tendency, and a bonded palatal retainer or continued retainer wear is often recommended long-term. Functional shifts that have been fully corrected in growing patients tend to be more stable once the jaw is in the correct position.
