Underbite
Underbite (Pronunciation: /ˈʌndərbaɪt/)
An underbite is a type of malocclusion or misalignment of the teeth where the lower teeth protrude in front of the upper teeth when the mouth is closed. This condition is also known as prognathism or Class III malocclusion.
Etymology
The term "underbite" is derived from the English words "under," meaning below or beneath, and "bite," referring to the act of closing the teeth together. The term thus refers to the condition where the lower teeth are positioned below the upper teeth when biting.
Symptoms
Symptoms of an underbite may include:
- Difficulty biting or chewing
- Speech difficulties
- Breathing through the mouth
- Changes in facial appearance
- Jaw pain
Causes
Underbites are usually caused by genetic factors, meaning they are often inherited. Other causes can include childhood habits such as thumb sucking, prolonged use of a pacifier, or tongue thrusting.
Treatment
Treatment for an underbite can vary depending on the severity of the condition. Options may include:
- Orthodontic treatment: This involves the use of devices such as braces or retainers to gradually move the teeth into the correct position.
- Orthognathic surgery: In severe cases, surgery may be required to correct the position of the jaw.
- Dental restoration: This involves reshaping or rebuilding the teeth using crowns, veneers, or bonding.
Related Terms
- Overbite: A condition where the upper teeth protrude over the lower teeth when the mouth is closed.
- Crossbite: A condition where some of the upper teeth fit inside the lower teeth when biting.
- Open bite: A condition where the upper and lower teeth do not meet when the mouth is closed.
