A deep bite is also called a deep overbite, excessive overbite, or closed bite. It is a malocclusion where the upper front teeth excessively overlap the lower front teeth when the mouth is closed.
This can cause the lower front teeth to bite into the gum tissue or palate behind the upper front teeth. A deep bite can sometimes also be an esthetic concern. It may also indicate that there are other issues to address.

A deep overbite is usually an esthetic problem, as some people are embarrassed about their smile. However, it can also cause various dental problems.
An untreated, deep overbite can lead to the following complications:
A deep bite occurs due to many reasons. This includes:
We recommend at-home clear aligners if you have mild teeth misalignment. View our top recommendations.
Treatment for a deep bite usually requires going to an orthodontist. Extreme cases often require at least two years of treatment and maintenance afterward.
Other factors that affect the length and kind of treatment plan include:
A deep bite is often treated with braces or clear aligners like Invisalign. Orthodontists will examine your teeth to determine whether the front or back teeth are causing the overbite.
Traditional braces and clear aligners can provide enough force to move the problem teeth slowly. By repositioning the teeth into the correct position, your dentist creates enough height in your lower teeth to improve the overbite.
Some orthodontists will choose to treat deep bites with myofunctional appliances. These orthodontic tools take advantage of the force your jaw and mouth muscles produce to change your teeth’s placement.
This type of treatment is most commonly prescribed for children with deep bites. The treatment combines children’s growth potential and the appliances to influence the growth of their lower jaw bones (mandible).
When deep bites are caused by tooth damage or loss, people may need additional dental work, like implants. Losing teeth can lessen the height of your lower arch, causing a deep bite.
A dental implant will restore the height of your lower arch. It can also support proper jaw alignment.
If not treated early, a deep overbite worsens over time and may need jaw surgery to correct. Teeth wear down with clenching and grinding, making the overbite more pronounced and noticeable.
A misaligned jaw also causes some deep bites. This cannot be corrected with braces alone, so your orthodontist may suggest surgery to correct the alignment.
A deep bite is when the upper front teeth excessively overlap with the lower front teeth. It’s usually caused by teeth misalignment but can also occur due to tooth loss or jaw misalignment.
The most common treatment for this dental condition is traditional braces or clear aligners. Dentists may also recommend jaw surgery in certain cases.
A deep bite should always be corrected if possible. Aside from the treatment’s esthetic benefits, it can also prevent other oral conditions, including:
