Overbite
Excessive vertical overlap of upper over lower front teeth — a deep overbite can cause wear and discomfort.
Overview
A normal overbite involves the upper front teeth slightly overlapping the lower ones — typically by 1–3 mm. A deep overbite describes significantly greater overlap, where the lower front teeth may bite into the roof of the mouth or be almost hidden by the upper teeth.
Deep overbites can cause excessive wear on the lower front teeth, gum irritation, and jaw muscle fatigue. They also sometimes limit the room available to restore worn teeth — so addressing the overbite first can change the whole treatment plan.
For most adult overbite cases, in-house clear aligners (Pro Aligners) are an effective option; complex skeletal overbites are referred to a trusted orthodontic specialist. The result is both cosmetic and functional.
Common symptoms
- Upper teeth cover lower teeth excessively
- Tooth wear on lower front teeth
- Jaw discomfort or muscle fatigue
- Biting the gum behind the upper front teeth
- A 'gummy' smile
Common causes
- Genetic jaw relationship
- Teeth lost from the back of the mouth
- Long-term grinding
- Relapse after prior orthodontics

Related conditions
Overjet
Horizontal projection of upper front teeth beyond the lower — can affect appearance, lip closure and trauma risk.
Crossbite
One or more upper teeth sit inside the lower teeth — can affect bite function and tooth wear.
Open Bite
A bite where upper and lower teeth don't meet when closed — can affect chewing, speech and tooth wear.
Teeth Grinding
Involuntary clenching or grinding — often during sleep — that can wear teeth and strain the jaw.
