An overbite is a common dental condition where the upper front teeth overlap the lower front teeth when you bite down, but what actually causes it?
If not addressed, it can cause discomfort and even lead to other dental issues.
Wondering what you can do to fix an overbite? In this article, we’ll explore what an overbite is, its causes, and how it can be corrected using Smilelign clear aligners.
What is an overbite?
An overbite occurs when the upper teeth overlap the lower teeth more than what is considered ideal. This condition can vary in severity, and there are two types:
- Vertical Overbite: This is when the upper teeth excessively overlap the lower teeth vertically.
- Horizontal Overbite: In this case, the upper teeth jut out further than the lower teeth horizontally.
Overbites are often classified as mild, moderate, or severe, with more significant cases potentially leading to jaw discomfort, difficulty chewing, and wear on the teeth.
Causes of an overbite

An overbite can be caused by a number of factors, many of which are hereditary or related to childhood habits. Here are some of the main causes.
- Genetics
- Thumb sucking
- Jaw growth issues
- Teeth misalignment
If you’ve noticed your teeth overlap more than you’d like or feel discomfort when chewing, it’s worth looking into treatment options sooner rather than later.
Why should you fix an overbite?
While an overbite may not always cause immediate pain, it can lead to several long-term issues if left untreated. Therefore, correcting an overbite will not only improve the appearance of your teeth but also enhance your overall dental health and comfort.
Wear on teeth
The excess overlap can cause the upper and lower teeth to rub against each other more than normal, leading to tooth wear, chips, and sensitivity.
Jaw pain
Misalignment of the bite can put additional strain on the jaw muscles, potentially causing discomfort or even headaches.
Difficulty chewing
A severe overbite may make it harder to chew properly, which can affect your eating habits and overall comfort.
Speech challenges
In some cases, an overbite can affect speech, making it difficult to pronounce certain sounds clearly.
