What is Cross Bite?

A cross bite happens when some upper teeth sit inside the lower teeth when you bite. It can affect the front teeth, back teeth, or both. This can make chewing or biting difficult and may cause jaw pain or cause some teeth to wear down faster than others. Cross bites can happen because of how teeth grow, jaw size differences, or habits like thumb sucking. If not treated early, a cross bite can get worse over time.

Treatment Process

Day-Time Invisible Aligners – Quick Smile Correction
Day-Time invisible aligners are suitable for people who want faster teeth straightening and don’t mind wearing aligners during the day. These aligners are usually worn for most of the day and night to keep steady pressure on the teeth.If worn properly, Day-Time aligners can show results in a shorter period. Many patients select this option when they want quick changes, especially before special occasions. Following the recommended wear time helps achieve the best results.
Night-Time Invisible Aligners – Discreet Treatment at Night
Night-Time invisible aligners are designed for people who prefer not to wear aligners during daytime hours. These aligners are worn only while sleeping, making them a convenient and private option.Since they are worn for fewer hours, the treatment can take a little longer compared to Day-Time aligners. However, they are ideal for busy lifestyles, public-facing jobs, or personal comfort. Night-Time aligners provide an easy and comfortable way to improve your smile over time.

Expected Timeline and Outcomes

Treatment time can be different for each person, depending on how severe the cross bite is and how much the teeth need to move. Some patients begin to see noticeable improvements within just a few months, while full treatment usually takes longer to achieve the best results. By the end of the process, patients can enjoy a properly aligned bite, straighter teeth, and better overall oral health, all while using a comfortable and discreet invisible aligner system.

Frequently asked question


A crossbite is a type of dental misalignment where the upper teeth fit inside the lower teeth when you bite down. It can affect one tooth or several and can occur in the front (anterior crossbite) or back (posterior crossbite) of the mouth.

Common causes include:


  • Genetics (inherited jaw size or tooth alignment)

  • Delayed or abnormal eruption of baby or permanent teeth

  • Prolonged habits like thumb-sucking or pacifier use

  • Mouth breathing or abnormal swallowing patterns

  • Jaw growth imbalance (upper or lower jaw growing too much or too little)

Ideally, during childhood or early adolescence, when the jaw is still growing. However, adults can also benefit from orthodontic or surgical correction.
