Crossbite
One or more upper teeth sit inside the lower teeth — can affect bite function and tooth wear.
Overview
A crossbite describes a bite where one or more upper teeth sit behind (anterior crossbite) or inside (posterior crossbite) the lower teeth when biting together. It can affect a single tooth or an entire arch, and it sometimes forces the jaw to shift sideways when closing.
Crossbites are worth correcting. Left untreated, they can cause uneven tooth wear, recession on affected teeth, and — in some cases — asymmetric jaw development in younger patients.
Modern orthodontics offers several predictable routes to correction. For most adult cases we use clear aligners (Pro Aligners) as the in-house option; if your case is too complex for aligners we'll refer you to a trusted orthodontic specialist. We build a plan around the specific bite, the supporting bone, and the patient's lifestyle preferences.
Common symptoms
- Teeth crossing over when biting
- Uneven tooth wear
- Jaw discomfort or shifting
- Changes in facial symmetry
- Chewing on one side
Common causes
- Genetic jaw size or shape
- Retained baby teeth
- Early habit (thumb sucking, prolonged dummy use)
- Late-erupting adult teeth

Options-based treatment plan
We present all suitable treatment options with realistic outcomes, timings and written costs so you can make an informed decision at your own pace.
Related conditions
Overbite
Excessive vertical overlap of upper over lower front teeth — a deep overbite can cause wear and discomfort.
Underbite
Lower front teeth sit in front of the upper — may be dental or skeletal, with tailored correction pathways.
Crowded Teeth
Insufficient space in the dental arch causes teeth to overlap, rotate or push out of line.
Open Bite
A bite where upper and lower teeth don't meet when closed — can affect chewing, speech and tooth wear.
