A crossbite — where upper and lower teeth don't line up correctly when biting down — can affect chewing, speech, and long-term jaw health if left untreated. Here's how Invisalign corrects it.
A crossbite occurs when one or more upper teeth sit inside (rather than outside) the lower teeth when you bite down — the opposite of a normal bite relationship. It can affect just the front teeth (anterior crossbite) or the back teeth (posterior crossbite), and each requires a slightly different treatment approach.
Anterior vs Posterior Crossbite
Anterior crossbite affects the front teeth and is often visible as a single tooth or a small group sitting behind the lower teeth. Posterior crossbite affects the back molars and premolars and is frequently linked to a narrow upper jaw. Both types are treatable with Invisalign using targeted attachments, though posterior crossbite correction sometimes benefits from combining aligners with auxiliary appliances in growing patients.
Why Untreated Crossbite Matters
Treatment Timeline & Cost
Most adult posterior crossbite cases are treated with Invisalign Moderate to Comprehensive plans, typically 9–18 months, starting from ₹1,60,000. Anterior crossbite involving a single tooth can sometimes be resolved faster with Invisalign Lite, in 3–6 months.
