Bite problems, explained without the orthodontic jargon
Straight teeth are only part of orthodontics. The way the upper and lower teeth fit together matters too.
Orthodontists evaluate the bite because a problem can involve tooth position, jaw relationships, growth, or a combination of all three. The right treatment depends on which part of the system is actually causing the problem, which is why bite correction at SmileWorks in Tallahassee starts with a free evaluation by an orthodontic specialist.
Overbite
"Overbite" is often used casually to describe several different things. Clinically, it generally refers to how much the upper front teeth vertically overlap the lower front teeth.
A deeper-than-normal bite can sometimes contribute to tooth wear, gum contact, or other functional concerns. Treatment depends on age, severity, tooth position, and jaw relationships.
Overjet
Overjet describes how far the upper front teeth project forward relative to the lower front teeth.
Significant overjet can make the front teeth more vulnerable to injury and may be related to tooth position, jaw relationships, or both.
Underbite
An underbite occurs when the lower front teeth sit ahead of the upper front teeth. In growing children, early evaluation can be especially useful because the orthodontist can determine whether the problem is primarily dental or reflects a developing jaw relationship.
Not every underbite is treated the same way, and timing can matter.
Crossbite
A crossbite occurs when one or more upper teeth bite inside the lower teeth. Crossbites can involve the front or back teeth and may sometimes cause the lower jaw to shift to one side when the patient bites down.
Selected crossbites are among the problems orthodontists may choose to address earlier in childhood, sometimes with a palatal expander.
Open bite
An open bite means some upper and lower teeth do not meet when the mouth closes. It can be influenced by tooth position, growth pattern, oral habits, tongue posture, or a combination of factors.
Treatment depends heavily on the cause.
Crowding and spacing
Crowding occurs when there is not enough room for teeth to align normally. Spacing occurs when excess room leaves noticeable gaps.
Both can be treated orthodontically, but the plan may differ depending on tooth size, arch width, missing teeth, eruption patterns, and the bite.
Why age matters, but diagnosis matters more
Children may benefit from growth-related treatment for selected bite problems. Teens often complete comprehensive treatment as permanent teeth finish erupting. Adults can also correct many bite and alignment problems, although treatment planning must account for mature jaw relationships and dental health.
The same visible "underbite" or "crowding" can have different causes in two different people. That is why treatment should start with an orthodontic diagnosis rather than choosing an appliance from a website.
Questions families ask
Can Invisalign fix an overbite or underbite?
Clear aligners can treat many bite problems, but whether they are the best option depends on the cause and severity of the problem.
Should a child with a crossbite see an orthodontist early?
Yes. A crossbite is a reasonable reason to schedule an early orthodontic evaluation because selected crossbites can benefit from treatment while a child is growing.
Can adults correct bite problems?
Many adult bite problems can be treated orthodontically. The approach depends on the teeth, gums, jaw relationships, and severity of the problem.
How do I know what kind of bite problem I have?
An orthodontic exam is the most reliable way to determine whether the issue is tooth position, jaw position, or both.
