Many people associate beautiful smiles with straight, well-aligned teeth. Unfortunately, not everyone is naturally gifted with perfect teeth. Some people are born with an overbite, which can affect their appearance and oral health. This guide will help you understand the differences between overbite and normal teeth, their causes and effects, and their treatment options.
What is an overbite?
While an overlap should exist, an overbite occurs when the upper front teeth overlap the lower front teeth too much. Overbites can be mild to severe and may affect the smile, chewing, or general oral health.
Types of overbite
An Overbite can be classified into two types:
Skeletal overbite
The skeletal problem with the jawbone structure is when the upper jaw grows to be longer than the lower jaw.
Dental overbite
It relates to the upper teeth being misaligned and not fitting together properly.
What are normal teeth?
Normal teeth naturally align, with the upper teeth slightly overlapping the lower teeth, and there isn't any strain while biting and chewing. A well-aligned bite reduces the risk of dental problems and promotes optimal oral health.
Causes of overbite
The following are some of the causes of an overbite:
Genetics
Inborn features predispose a few people to jaw forms that cause the natural likelihood of having an overbite.
Thumb sucking
Thumb sucking in childhood can push teeth out of line.
Pacifier use
An overbite could result from prolonged use of a pacifier.
Teeth grinding
Continuous teeth clenching or grinding can cause misalignments, which worsens the symptoms of overbite.
Jaw growth issues
The reason behind an overbite can be uneven growth of the upper and lower jaw.
Tooth loss
Tooth loss creates gaps, leading to the gradual shifting of surrounding teeth. This misalignment can cause bite issues, jaw discomfort, and difficulty chewing.
Effects of overbite
An untreated overbite may lead to the following concerns:
Aesthetic problem
An overbite, inherited or otherwise, alters the face contour, instilling self-esteem problems.
Jaw pain
The overbite increases tension in the jaw muscle and causes pain and discomfort.
Tooth wear
Poorly aligned teeth could cause uneven damage to them.
Gum Problems
Due to a deep overbite, the lower teeth can sometimes touch the gums behind the upper teeth, irritating them.
Difficulty Chewing
Severe overbite may make chewing difficult, leading to digestive complications.
Correcting overbite
Several methods can be employed in correcting an overbite:
Braces
Traditional braces are one of the most effective treatments for correcting an overbite. They use brackets and wires to slowly and steadily move teeth into proper alignment.
Clear aligners
For a discreet treatment, clear aligners like CasperSmile are used to straighten minor-to-moderate overbites. They are custom-made, removable trays, that gradually shift teeth into appropriate positions without metal brackets.

Palate expanders (For children & teens)
A palate expander can be used as a preventive or corrective treatment for an overbite while a child or teen is still growing. It is most effective during jaw development.
Jaw surgery
Orthognathic surgery may be used in extremely severe overbites caused by jaw misalignment. This type of surgery repositions the jaw and fixes it with plates or screws for balanced bite maintenance, which is rarely used in children but rather advised for adults with considerable skeletal problems.
Tooth extraction
Tooth extractions may be necessary when you have an overbite due to overcrowding. When certain teeth are extracted, they leave space for the remaining teeth to shift into a better position and improve the bite.
Overbite vs. normal: Key differences
Feature | Normal Teeth | Overbite |
Teeth Alignment | Slight overlap of upper teeth | Excessive overlap of upper teeth |
Jaw Function | Normal chewing and speaking | Difficulty in chewing and speaking |
Oral Health | Lower risk of dental issues | Increased risk of cavities, gum problems, and jaw pain |
Treatment Needed | No treatment required | May need braces, aligners, or surgery |
Aesthetic Impact | Balanced facial structure | Can cause protruding lips or receding chin |
