Types of Bite Problems and Their Treatment

A bite problem can be easy to miss at first. Your child may chew comfortably and smile with confidence, yet their teeth may not meet in the right positions. For adults, a bite concern may show up as uneven tooth wear, jaw tension, or a retainer that no longer fits. Understanding the different types of bite problems can make it easier to know when an orthodontic evaluation may be helpful.

A healthy bite is about more than straight-looking teeth. It describes how the upper and lower teeth fit together when the mouth closes. When that relationship is off, certain teeth can receive too much pressure, gums may be harder to clean, and jaw function can be affected. Some concerns are mild and mostly cosmetic. Others benefit from treatment to protect long-term oral health.

What are bite problems?

Orthodontists use the term malocclusion to describe teeth or jaws that do not align as intended. A malocclusion may involve the front teeth, back teeth, one side of the mouth, or the relationship between the upper and lower jaws.

Bite problems can occur even when teeth appear relatively straight. Conversely, crowded or spaced teeth do not always mean a person has a significant bite issue. That is why a personalized examination matters. It allows an orthodontic specialist to look at tooth position, jaw growth, facial balance, function, and the health of the teeth and gums together.

Common types of bite problems

Overbite

An overbite occurs when the upper front teeth overlap the lower front teeth. A small amount of vertical overlap is normal. However, when the upper teeth cover too much of the lower teeth, it is often called a deep bite.

A deep overbite can cause the lower teeth to contact the roof of the mouth or place excess pressure on the lower front teeth. Over time, that pressure may contribute to enamel wear, gum irritation, or chipping. Treatment may involve braces or clear aligners, depending on the bite, tooth movements needed, and patient age.

Overjet

Overjet is sometimes confused with an overbite, but it refers to the horizontal distance between the upper and lower front teeth. When the upper front teeth extend too far forward, they may be more vulnerable to injury during a fall, sports activity, or other impact.

Overjet can result from tooth position, jaw growth patterns, or habits such as prolonged thumb sucking. In growing children, an orthodontist may monitor jaw development and recommend treatment at the timing that offers the greatest benefit.

Underbite

An underbite occurs when the lower front teeth sit in front of the upper front teeth. In some cases, only one or two teeth are involved. In others, the lower jaw has developed farther forward than the upper jaw.

Because an underbite can be related to jaw growth, early evaluation is especially valuable. Treatment may begin while a child is still growing, or it may be planned in stages. Adults can also achieve meaningful improvement, although the right approach depends on the severity of the jaw relationship and the individual treatment goals.

Crossbite

A crossbite happens when some upper teeth close inside the lower teeth instead of outside them. It may affect one front tooth, several back teeth, or an entire side of the mouth.

A crossbite can contribute to uneven wear and may cause the jaw to shift to one side when closing. In a growing child, correcting a crossbite at the appropriate time can help support more balanced development. Because crossbites vary widely, treatment may include braces, clear aligners, or an appliance designed for the specific bite concern.

Open bite

With an open bite, the upper and lower teeth do not touch in a certain area when the mouth is closed. A front open bite leaves a visible space between the front teeth, while a posterior open bite affects the back teeth.

Some people with an open bite have difficulty biting into foods such as sandwiches or pizza. Speech can also be affected in certain cases. Open bites may be associated with jaw growth, tongue posture, or oral habits. Successful treatment often addresses both tooth alignment and the factors contributing to the bite.

Crowding and tooth rotation

Crowding occurs when there is not enough space in the jaw for teeth to line up properly. Teeth may overlap, twist, or erupt outside the dental arch. While crowding is not always a bite problem on its own, it often occurs alongside one.

Crowded teeth can be harder to brush and floss effectively, particularly around the gumline. Orthodontic treatment creates a healthier, more functional arrangement by carefully making space and guiding teeth into their intended positions.

Spacing and missing teeth

Spaces between teeth can develop when teeth are smaller than the available jaw space, when a tooth is missing, or when teeth have shifted over time. Larger gaps may affect how neighboring teeth meet and how forces are distributed during chewing.

Orthodontic care can close spaces, preserve space for a future restoration, or position teeth for coordinated treatment with a general dentist or other dental specialist. The best plan depends on why the spacing developed and the long-term goal for the smile.

What causes bite problems?

Many bite concerns are influenced by genetics. A child may inherit a jaw size, jaw position, or tooth-size pattern similar to a parent or close relative. Other factors can include early loss of baby teeth, injury, prolonged pacifier use, thumb sucking, tongue posture, and changes that occur as adult teeth erupt.

Not every bite problem is preventable, and parents should not feel blamed when one is identified. What matters most is recognizing concerns early enough to make informed decisions. The American Association of Orthodontists recommends an orthodontic checkup by age 7, when a mix of baby and permanent teeth can reveal how the bite is developing.

Signs it may be time for an orthodontic evaluation

Some bite problems are visible, but others are noticed through daily habits. Difficulty chewing, frequent biting of the cheeks, mouth breathing, jaw discomfort, teeth that appear to wear unevenly, or front teeth that do not meet normally can all be worth discussing with an orthodontist.

Parents may also notice that a child shifts their jaw when closing, avoids certain foods, or has teeth erupting in unusual positions. Adults may seek care because a past orthodontic result has changed, a retainer no longer fits, or teeth have gradually moved. Orthodontic care is not limited to childhood, and treatment can be tailored for patients at many stages of life.

How bite problems are treated

There is no single treatment for every malocclusion. The right plan depends on the type and severity of the bite problem, facial and jaw development, oral health, treatment goals, and the patient's ability to follow care instructions.

Braces provide precise control for a wide range of tooth and bite movements. Clear aligner treatment can be an excellent option for many teens and adults who want a more discreet approach. Some younger patients benefit from early treatment that guides growth or creates room for permanent teeth, followed by comprehensive treatment later. In more complex cases, treatment may involve collaboration with a general dentist, oral surgeon, or other specialist.

Modern orthodontic planning uses detailed imaging and digital impressions to evaluate tooth positions with greater precision. At Dixon Orthodontics, a Board Certified Orthodontist can explain what is happening with your bite, what treatment may involve, and whether monitoring is the most appropriate next step. Not every concern requires immediate treatment, and a thoughtful recommendation should account for your comfort, health, and long-term results.

A bite that feels normal is not always a bite that is functioning at its best. A professional orthodontic evaluation can replace uncertainty with a clear plan, whether that means treatment now, treatment later, or the reassurance that your smile is developing well.
