How is an overbite treated?
An overbite, or deep bite, is usually treated with orthodontics that raises the bite by moving front teeth vertically and levelling the curve of the teeth. Fixed braces suit most cases; aligners suit selected mild to moderate ones, and skeletal cases may need jaw surgery. At Gangnam One Day Dental Clinic, Dr. Kim Do-hoon leads treatment, typically lasting 12 to 30 months.

What counts as an overbite
Overbite is the vertical overlap of the upper front teeth over the lower ones. A small overlap of about 2 to 3 mm is normal. When the upper teeth cover much of the lower teeth, or the lower teeth bite into the gum behind the upper teeth, it is called a deep bite.
People often confuse overbite with overjet, which is how far the upper teeth stick forward horizontally. Forward-flared teeth are covered on our buck teeth page.
- Lower teeth hidden when you bite together
- Lower front teeth touching the gum behind the upper teeth
- Wear on lower front teeth or upper front tooth edges
- Jaw discomfort in some patients
Treatment options
Most deep bites are corrected with fixed appliances such as metal braces or self-ligating brackets, which give control over vertical movement. Selected mild to moderate cases can be treated with Invisalign or other aligners.
When the cause is a jaw size mismatch, especially in adults, orthodontics may be combined with jaw surgery. Dr. Kim Do-hoon plans surgical orthodontics for these cases.

A deep bite can wear the front teeth, irritate the gum behind the upper teeth and make future crowns or veneers harder to place. Correcting it can make the bite more stable and the front teeth easier to restore later.
Because Gangnam One Day Dental Clinic also has occlusion-focused care, including T-Scan digital bite analysis, bite concerns can be reviewed across departments where relevant.

Things to know before you decide
- Deep bites have a known tendency to relapse; retainer wear is important.

- Aligners may not achieve enough vertical change in severe cases.
- Tenderness after adjustments and hygiene demands of fixed braces.
- Active gum disease must be treated first.
