Underbite
Lower front teeth sit in front of the upper — may be dental or skeletal, with tailored correction pathways.
Overview
An underbite — sometimes called a reverse bite — occurs when the lower front teeth sit in front of the upper front teeth when biting together. It can involve just a few teeth or the whole arch.
Underbites can be dental (the teeth have tipped) or skeletal (the lower jaw is genuinely longer than the upper). The distinction matters because skeletal underbites in adults may need a combined orthodontic–surgical approach for a stable, functional result.
We assess both the dental and skeletal components with clinical examination and imaging, then discuss realistic options — aligners, braces, combined therapy, or surgical orthodontics — so you understand the trade-offs of each route.
Common symptoms
- Lower teeth sit in front of upper teeth
- Difficulty biting or chewing
- Jaw discomfort or muscle fatigue
- Speech differences
- Changes in facial profile
Common causes
- Genetic jaw relationship
- Forward lower jaw growth
- Habitual forward posturing of the lower jaw
- Missing upper teeth
Our approach
Comprehensive examination
We begin with a focused clinical examination, digital X-rays where indicated, and a full medical and dental history to build a complete picture of your symptoms.
Transparent diagnosis
You receive a clear explanation of what we find, shown on-screen with intra-oral imaging so you can see exactly what we see — no jargon, no pressure.
Options-based treatment plan
We present all suitable treatment options with realistic outcomes, timings and written costs so you can make an informed decision at your own pace.
Related conditions
Overbite
Excessive vertical overlap of upper over lower front teeth — a deep overbite can cause wear and discomfort.
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.
Crowded Teeth
Insufficient space in the dental arch causes teeth to overlap, rotate or push out of line.
