An overbite is a malocclusion with an increased vertical overlap between the upper and lower front teeth. In some cases the overbite is so deep that the lower teeth bite into the roof of the mouth causing pain and inflammation of the gum.
Many factors can cause an overbite. They include:
Two types of overbite exist. They include:
A dental overbite is when developmental issues occurs in a child, such as overcrowding and other factors, which result in the lower front teeth over erupting and increasing the overbite. A skeletal overbite occurs when the jaw bone develops abnormally.
The IOTN system classifies overbite issues in children, as shown in the table below.
|Type of overbite||Size||Cause||Surgery needed?||Braces needed?|
|Normal||2 – 4mm||Usually dental-related||Unlikely||Possibly|
|Deep||4 – 8mm||Skeletal or dental||Unlikely||Yes|
|Severe||9mm and above||Skeletal or dental||Likely||Yes|
Treating an overbite is necessary for several reasons, as an untreated deep overbite can cause
Early overbite correction in a child is more effective than correcting this problem in adulthood. In adults, the teeth and jawbones are fully developed, which makes repositioning them more difficult.
A normal overbite is about 2 – 4mm, so you don’t need to worry about treatment if your top teeth slightly overlap the bottom teeth.
Your orthodontist may recommend different options to correct an overbite. The most suitable overbite treatment will depend on its cause and the severity of the case.
Many people with an overbite undergo braces treatment as they are effective and give a long-term result when combined with a retainer. The treatment duration may be between 1 – 3 years long depending on the other aspects of the bite that also need to be corrected.
If you opt for private treatment, you may get clear braces which are less noticeable than the traditional metal braces. Before braces treatment for an overbite, ask your orthodontist for before and after pictures of past patients. This should give you an idea of what to expect after your treatment and may motivate you to undergo yours.
Invisalign can effectively correct mild to moderate overbites. Your Orthodontist will let you know whether Invisalign is a suitable treatment option in your case.
If an overbite results from a skeletal discrepancy, jaw surgery may be necessary. This procedure is also known as orthognathic surgery. Surgery can help shape a poorly developed mandible or lower jaw. Your face may look slightly different after jaw surgery and will be more in proportion and in harmony.
