Buck teeth, also known as an overbite or protruding front teeth, are one of the most common dental alignment issues affecting children and adults alike. While the term “buck teeth” is often used casually, the clinical term is a Class II malocclusion, which describes the upper front teeth significantly overlapping the lower teeth.
At Clean Smiles in Edmonton, we help patients correct overbites with modern, discreet, and effective treatment options. In this guide, we’ll explain what causes buck teeth, why they matter, and how they can be treated or prevented.
What Are Buck Teeth (Overbite)?
A dental overbite refers to the vertical and horizontal overlap of the upper front teeth over the lower front teeth. In mild cases, this overlap is barely noticeable and often does not require treatment. However, a deep overbite or severe protrusion of the top teeth (when upper teeth stick out) can interfere with chewing, speaking, and self-confidence.
Buck teeth are not just a cosmetic concern—they can cause long-term dental and oral health problems if left untreated.
Common Causes of Buck Teeth
Understanding buck teeth and the root cause of an overbite is the first step in deciding the right treatment. Here are the most common causes:
- Genetics: If your parents had an overbite or jaw misalignment, you’re more likely to inherit it.
- Thumb sucking and pacifier use: Persistent thumb sucking or pacifier use beyond age 3 can push the upper teeth forward.
- Tongue thrusting: When the tongue presses against the front teeth during swallowing or speaking, it can cause tooth movement over time.
- Jaw growth imbalance: An underdeveloped lower jaw or overgrown upper jaw may result in a visible overbite.
- Missing or extra teeth: Tooth loss or overcrowding can shift surrounding teeth and alter the bite.
Why an Overbite Should Be Corrected
Many people think buck teeth are simply a cosmetic issue, but the implications go beyond appearance. A significant overbite can lead to:
- Tooth wear and enamel erosion due to constant pressure between misaligned teeth
- Jaw pain or TMJ dysfunction from improper bite alignment
- Speech difficulties, such as lisping or trouble pronouncing certain sounds
- Difficulty chewing and increased risk of accidental biting of the inner cheeks or lips
- Higher risk of injury to prominent front teeth, especially in children
Correcting an overbite early can improve both function and confidence while reducing the risk of future dental complications.
Overbite Treatment Options
At Clean Smiles, we offer several proven options to correct an overbite, depending on its severity and the patient’s age.
Braces
Traditional braces remain one of the most effective ways to realign teeth and correct jaw positioning. They gradually move the teeth into their proper alignment using brackets and wires. Braces can treat moderate to severe overbites in both teens and adults.
Clear Aligners (Invisalign®)
Clear plastic aligners are a discreet, convenient option for treating mild to moderate overbites. They work by applying gentle pressure to gradually shift teeth into position. Invisalign is popular among adults who want to correct their bite without noticeable metal brackets by using invisible treatment in order to achieve a straighter smile.

Orthodontic Appliances
In younger patients, orthodontists may use growth modification devices such as headgear or functional appliances to guide proper jaw development before or during early adolescence.
Tooth Extraction
In cases of overcrowding, strategic tooth removal may be necessary to create space and allow for proper alignment.
Jaw Surgery (Orthognathic Surgery)
For extreme skeletal overbites where the jaw alignment is severely off, surgery may be recommended in combination with orthodontic treatment.
Can Buck Teeth Be Prevented?
Some cases of overbite are hereditary and can’t be prevented entirely, but early habits and dental care can reduce the risk or severity:
- Encourage children to stop thumb sucking by age 3
- Avoid long-term pacifier use
- Treat tongue thrust issues early with a speech therapist or orthodontist
- Schedule regular dental checkups to catch bite issues early
- Maintain proper spacing and monitor for overcrowding in children’s teeth

Frequently Asked Questions
What causes a severe overbite and can it affect my oral health?
It can be caused by a combination of genetics, childhood habits like thumb sucking or tongue thrusting, and issues during jaw development. When upper teeth stick too far out over the lower teeth, it may lead to uneven wear, jaw pain, and even difficulty with chewing and speaking. Over time, this misalignment can impact oral health by increasing the risk of tooth decay, gum disease, and damage to the remaining teeth due to abnormal bite pressure.
Can childhood habits lead to overbite problems in adult teeth?
Yes, prolonged thumb sucking, use of pacifiers, and tongue thrusting can push the permanent teeth and adult teeth forward as they grow in, contributing to protruding teeth and misalignment. These habits alter the position of developing teeth and the jaw structure, which may require orthodontic treatment such as traditional braces or clear aligners later in life.
What are the long-term effects of untreated protruding teeth or missing teeth?
Buck teeth are more vulnerable to injury and can affect self-esteem, especially in children and teens. Missing teeth can worsen bite alignment issues and place stress on the remaining teeth, leading to further dental health complications. Without overbite treatment, these conditions can contribute to gum problems, shifting of teeth, and even TMJ disorders in the long run.
How can I tell if my child’s overbite needs orthodontic treatment?
If your child’s upper teeth jut out significantly over the lower teeth, or if they have difficulty closing their mouth fully, they may benefit from an orthodontic evaluation. Early signs include teeth grinding, speech issues, or visible spacing concerns. Addressing these issues early with treatment can prevent more complex problems and support healthy oral health as your child grows.
