Your top teeth usually go over your bottom teeth due to a combination of factors including genetics, childhood habits, and jaw structure. This alignment, known as an overbite, is common, but if excessive, it can cause problems.
Causes of Overlapping Teeth
Several reasons can explain why your top teeth might overlap your bottom teeth:
- Genetics: Inherited traits often determine jaw size and shape, influencing tooth alignment. If your parents or other family members have overbites, you are more likely to develop one too.
- Childhood Habits: Habits like thumbsucking or prolonged use of a pacifier can exert pressure on developing teeth and jaw, pushing them out of alignment over time.
- Jaw Size Discrepancy: If your upper jaw is larger than your lower jaw, or if your mouth simply doesn't have enough room for all your teeth, an overbite can result.
- Facial/Jaw Injury: Trauma to the face or jaw can displace the bones, altering the alignment of the teeth.
Understanding Overbite
An overbite is when the upper front teeth vertically overlap the lower front teeth. This is a normal dental alignment to a certain extent. However, when the overlap is too large, it can create problems.
| Contributing Factor | Explanation |
|---|---|
| Genetics | Inherited traits can affect the size and shape of the jaws, leading to an overbite. |
| Childhood Habits | Thumbsucking and pacifier use can push teeth out of alignment. |
| Jaw Size | Differing sizes between the upper and lower jaws can cause the upper teeth to protrude. |
| Facial Injury | Injuries that misalign the jaw can also lead to an overbite. |
Addressing an Overbite
If your overbite is severe, it is crucial to consult a dentist or orthodontist. They can recommend solutions such as:
- Braces: To move the teeth into correct alignment.
- Invisalign: A clear alternative to traditional braces.
- Jaw surgery: In extreme cases, surgery may be needed to reposition the jaw.
It's important to remember that not all overbites are problematic. However, if you have concerns, professional evaluation is essential for a tailored treatment plan.
