A crossbite is a type of malocclusion that occurs when the upper and lower teeth do not align properly. It’s a common dental issue that can affect the appearance and function of your smile. In this post, we’ll delve into the two main types of crossbites: Anterior Crossbite and Posterior Crossbite.
What is an Anterior Crossbite?
An anterior crossbite, also known as an underbite, occurs when the lower front teeth overlap the upper front teeth. This can happen due to:
- Misaligned teeth or jaw
- Overcrowding
- Genetics
- Thumb sucking or other oral habits
Symptoms:
- Difficulty biting or chewing food
- Jaw pain or clicking
- Aesthetic concerns
Treatment Options for Anterior Crossbite:
- Orthodontic treatment (braces or clear aligners)
- Dental restorations (veneers or crowns)
- Jaw surgery (in severe cases)
What is a Posterior Crossbite?
A posterior crossbite occurs when the upper back teeth bite inside the lower back teeth. This can lead to:
- Uneven wear on teeth
- Jaw strain
- Difficulty chewing
Causes:
- Narrow upper jaw
- Misaligned teeth or jaw
- Genetics
Treatment Options for Posterior Crossbite:
- Orthodontic treatment (braces or clear aligners)
- Palatal expanders (to widen the upper jaw)
- Dental restorations (crowns or bridges)
Why Treatment Matters
Untreated crossbites can lead to:
- Increased risk of tooth wear and damage
- Jaw pain and TMJ issues
- Decreased self-confidence
