Buck teeth are front teeth that stick out past the lower teeth, usually from genetics, thumb-sucking, or tongue thrusting. They can be fixed. Braces and clear aligners correct most cases, children may use functional appliances, and severe jaw-based cases may need surgery. There is no safe at-home fix, so start with an exam.
Buck teeth are common, and wanting to change how your smile looks is a reasonable concern. By the end of this article, you will know what causes buck teeth, which treatments fit which situations, and the steps from a first check to a retainer.
What Are Buck Teeth, and How Is an Overjet Different From an Overbite?
Buck teeth is the everyday name for upper front teeth that angle forward or sit too far in front of the lower teeth. Dentists call this an overjet (a horizontal gap between the upper and lower front teeth when you bite down). You may also hear "bunny teeth" or "protruding teeth" for the same thing.
An overbite is a different problem. It describes vertical overlap: how far the upper front teeth cover the lower ones when your mouth is closed. Some people have a deep overbite with no visible protrusion. Others have a large overjet and only a small overbite. Many people have both at once, which is why the two terms get mixed up.
Here is a simple way to tell them apart:
- Overjet: measured front to back. Think of how far the top teeth stick out.
- Overbite: measured up and down. Think of how much the top teeth cover the bottom teeth.
Both are common. A global review of studies across multiple continents found that approximately 20 percent of the population has an overjet. Separate global study data shows that roughly 22 percent of children and adults have an overbite. These two figures measure different things, so you should not add them together or treat them as one number. Both reports come from vendor-reported summaries, as of 2023.
Protrusion is especially visible in the preteen years. Research cited by the American Association of Orthodontists indicates that protruding teeth affect approximately 15 percent of American children between the ages of 12 and 15, according to Dental Products Report's 2016 coverage.
What Causes Buck Teeth in Humans?
Buck teeth come from a mix of inherited traits and habits, and often both play a part. Knowing the cause helps you and your dentist choose the right fix. These are the most common causes:
- Genetics: You can inherit a smaller lower jaw, a larger upper jaw, or teeth that are simply larger than the space available. Any of these can push the upper front teeth forward.
- Thumb-sucking: Steady pressure from a thumb or finger can tip the front teeth outward, especially if the habit continues as permanent teeth come in.
- Pacifier use: Long-term pacifier use can have a similar effect on a child's developing teeth and jaw.
- Tongue thrusting: This is when the tongue pushes forward against the front teeth during swallowing or speech. Over time, that repeated pressure can move the teeth out of position.
- Mouth breathing: Breathing through the mouth for long periods can change how the tongue and lips rest, which may affect tooth position.
Are Buck Teeth Hereditary?
Partly, yes. You do not inherit "buck teeth" as a single trait. You inherit jaw size, jaw shape, and tooth size, and those traits can combine to create a protruding smile. That is why the problem often runs in families.
Habits can add to what genetics start. A child with a slightly small lower jaw who also sucks a thumb may develop a larger overjet than either factor would cause alone.
Bite problems are widespread. A 2020 meta-analysis suggests that the worldwide prevalence of dental malocclusion (teeth that do not line up properly) is 56%, as reported by Medical News Today in 2022. If your teeth do not line up perfectly, you are in the majority.
Are Buck Teeth Just Cosmetic, or Is There a Health Risk?
For many people, buck teeth are mainly a matter of appearance. But a larger overjet can carry real health risks, and it is worth understanding them before you decide whether to treat it.
Does an Overjet Raise the Risk of Chipped or Knocked-Out Teeth?
It can. Front teeth that stick out are more exposed during falls, sports, and accidents. In a review of 1,367 orthodontic patient records, individuals with an overjet greater than 3 mm were 2.03 times more likely to experience incisor trauma if they had inadequate lip coverage, according to a 2026 report from Mosdent Hospital. In plain terms, when your lips cannot cover your front teeth, those teeth have less cushioning in a collision. This figure comes from a vendor-reported review, so treat it as a useful signal rather than a final answer.
Treatment may lower that risk. A study found that roughly one in three children treated for severe tooth protrusion saw a reduced risk of dental trauma, such as broken or knocked-out teeth, as reported by Dental Products Report in 2016.
Can Buck Teeth Affect Speech and Chewing?
Sometimes. When the upper and lower teeth do not meet well, some people find it harder to bite into certain foods or to make particular sounds clearly. The effect varies a lot from person to person, and many people with an overjet speak and eat without any trouble. If you notice a problem, a dentist can tell you whether your bite is the cause.
What Is the Emotional Effect of a Buck Teeth Smile?
Feeling self-conscious about your smile is a valid reason to seek care. Some people avoid smiling in photos or hold their lips over their teeth in conversation.
Every mouth is different, so consult with your dentist for guidance based on your own teeth, your age, and your goals.
How Do You Handle Buck Teeth in Kids?
If your child has protruding front teeth, the best first move is a check-up, not a wait-and-see approach. Early orthodontic evaluation lets a professional spot buck teeth in kids while the jaw is still growing, when some corrections are easier to guide.
Most parents first notice the problem when permanent front teeth come in, often between ages 6 and 8. That is also a good time for a first look, even if the teeth seem fine. If you are unsure about timing, our guide on when your child should see an orthodontist walks through the usual milestones.
Functional appliances are removable or fixed devices that use the growing jaw to improve how the upper and lower teeth fit together. A Cochrane review of teenage patients found that functional appliances achieved a mean reduction in overjet of 4.6 to 5.5 mm, according to the 2026 Mosdent Hospital report. That source is vendor-reported, so treat the number as a guide, not a promise for your child.
Timing matters because protrusion often shows up in the preteen years, so an early look gives you more choices.
Can You Get Rid of Buck Teeth?
In most cases, yes. A child's case may be corrected with a functional appliance first, then braces later if the teeth still need fine-tuning. Habits like thumb-sucking should stop as early as possible so they do not keep pushing the teeth forward.
You do not have to figure this out alone. Consult with your dentist or an orthodontist to decide what your child needs and when to start.
Can Buck Teeth Be Fixed? Braces, Aligners, and Surgery Compared
Yes, buck teeth treatment is well established, and the right choice depends on what is causing the protrusion, your age, and how severe it is. The table below compares the main options so you can see which one fits which situation. Costs are described in relative terms only, because your final fee varies based on several factors.

Traditional braces use metal or ceramic brackets glued to teeth and connected by wires. They are best for severe cases requiring precise control, and standard treatment time is approximately 12 to 36 months. You will need to take extra care cleaning around the brackets and avoid certain foods.
Invisalign uses a series of clear, removable plastic trays and suits mild to moderate cases. The trays must be worn 20 to 22 hours a day to work, and they may not be suitable for severe skeletal misalignments. If clear aligners appeal to you, this explanation of how clear aligners correct bite issues covers what to expect.
Surgery is reserved for cases where the jaw, not just the teeth, is out of position. Most people never need it.

Is There a Way to Fix Buck Teeth Without Braces or at Home?
Short answer: no at-home method moves teeth safely. If you are wondering how to fix overjet without braces, the honest answer is that your options are limited, and every one of them starts with an exam.
Moving teeth takes controlled, measured force and a plan based on X-rays of your roots and bone. Guessing without that information can loosen teeth, damage roots, or make your bite worse. That is why most dental sources warn against shortcuts.
Here is what does not work, and why:
- Facial or tongue exercises: Exercises can build habits, but they do not generate the sustained force needed to shift teeth into new positions.
- DIY devices and rubber bands: Homemade tools apply uneven pressure. They can harm gums and roots.
- "Fake" buck teeth products: You may see items sold online to hide or disguise protruding teeth. These are cosmetic gimmicks, not treatment, and they do not change where your teeth sit.
What Are the Limited Options Besides Braces?
For some mild cases, a dentist may suggest cosmetic dentistry to improve how teeth look. Dental bonding adds tooth-colored material to reshape the front teeth, and veneers are thin shells placed over the front surface. These can change the shape and appearance of your smile, but they do not move your teeth or fix a jaw-based problem. They are a fit only when a dentist confirms your teeth and bite are healthy enough for them.
Before you try anything, book an exam. A dentist can tell you whether your case is mild enough for a cosmetic approach or whether you need orthodontic care to correct the cause.
How to Fix Buck Teeth Step by Step
Fixing buck teeth follows the same basic path whether you are a teen or an adult: check, examine, scan, treat, adjust, and retain. Knowing the sequence helps you plan with confidence and ask better questions along the way.
- Check your lip closure at home. Stand in front of a mirror and relax your face. Do your lips close comfortably over your front teeth, or do they rest apart? Lips that cannot close without effort are a sign your front teeth may stick out enough to warrant a closer look. This check is only a first clue, not a diagnosis.
- Get a clinical exam. An orthodontist (a dentist with extra training in moving teeth and aligning jaws) examines your teeth, bite, and jaw. This is where you learn whether the cause is in your teeth, your jaw, or both.
- Have diagnostic X-rays and scans taken. Your provider takes X-rays and 3D digital scans or impressions. These show your roots, bone, and bite, and they let the team plan tooth movement safely.
- Start treatment with the right appliance. You either have brackets attached for braces or receive custom clear aligners. Your orthodontist chooses based on the severity of your overjet and your age. Children may begin with a functional appliance.
- Attend your adjustment visits. With braces, wires are tightened over time. With aligners, you switch to a new set of trays on schedule. Skipping visits or wearing trays fewer hours than prescribed slows your progress.
- Wear your retainer long term. Teeth tend to drift back after treatment. A retainer holds them in their new position, so wear it as directed, even when your smile looks finished.
Expect treatment to take a while. Standard braces treatment runs approximately 12 to 36 months, and your own timeline varies based on several factors, including how far your teeth need to move and how closely you follow instructions. Aligner wearers should plan on 20 to 22 hours of daily wear.
For children, a functional appliance often comes first in the sequence. In a Cochrane review of teenage patients, these appliances achieved a mean reduction in overjet of 4.6 to 5.5 mm. Braces may follow to fine-tune the result.
Where Can You Start Getting Your Buck Teeth Evaluated?
The easiest place to start is a general dental exam. Cost is a stressful part of any dental decision, and it should not stop you from getting answers. A first visit lets you learn what is going on and what your options are before you commit to anything.
Affordable Dentist Near Me (ADNM) is an independent, Texas-owned dental group with 17 offices across the Dallas, Fort Worth Metroplex, East Texas, and Central Texas. Ask about exam and X-ray costs and request a written treatment plan with exact fees before any work begins, so you see the numbers up front.
What Does a First Visit Look Like?
If your case calls for braces or aligners, your dentist can talk through next steps and point you toward an orthodontic referral. Think of the first visit as the place to get a clear starting point.
What Cosmetic Options Can You Discuss?
For mild cases, you can ask about cosmetic bonding or veneers, which can improve the shape and look of your front teeth after an exam. Professional whitening is also available. These options change appearance but do not move teeth, so your dentist will help you decide whether they fit your situation.
How Do You Pay for It?
Plan for costs before you book. Ask the office which insurance plans and payment options it accepts, and get fees in writing before treatment starts.

FAQs
Are buck teeth hereditary?
Partly. You do not inherit buck teeth as a single trait, but you can inherit jaw size, jaw shape, and tooth size, and those can combine to push the upper front teeth forward. That is why the problem often runs in families. Habits like thumb-sucking or tongue thrusting can add to what genetics start. A dentist can help sort out which factors apply to you.
Can bunny teeth be fixed?
Yes. "Bunny teeth" is another name for buck teeth, and treatment is well established. Braces and clear aligners correct most cases, children may use functional appliances, and severe jaw-based cases may need surgery. Which option fits you depends on your age, the cause, and how far the teeth stick out. An exam is the first step to a plan.
How to fix overjet without braces?
Your options are limited, and none of them is a do-it-yourself fix. Exercises, home devices, and "fake" products do not move teeth safely. For mild cases, a dentist may suggest cosmetic bonding or veneers to improve appearance, but these do not correct the bite. Start with an exam so you know what is safe for your teeth and what is not.
Can adults fix buck teeth, or is it only for kids?
Adults can fix buck teeth too. Braces and clear aligners work at any age when your teeth and gums are healthy. Children have an advantage because growing jaws can be guided with functional appliances, while adults with jaw-based problems may need surgery. Treatment simply looks different at different ages, so consult with your dentist or an orthodontist.
Do buck teeth cause speech problems?
Sometimes, but not always. When the upper and lower teeth do not meet well, some people find certain sounds or foods harder to manage. Many people with an overjet speak and eat without any trouble. If you notice a change in speech or chewing, a dentist can check whether your bite is involved and suggest next steps.
Will buck teeth go away on their own?
Not usually. Buck teeth caused by jaw and tooth structure do not correct themselves, and the position of permanent teeth tends to stay the same or worsen if a habit continues. Stopping thumb-sucking early can help prevent more movement, but it rarely reverses an established overjet. A dental exam shows whether your case needs treatment.
Conclusion
Buck teeth can be fixed, and the right treatment depends on what caused them and how far your teeth stick out. Braces and clear aligners handle most cases, children may benefit from functional appliances, and surgery is reserved for jaw-based problems. No home remedy or "fake" product moves teeth safely.
Your next move is simple: book an exam and ask what is causing your overjet and which options fit your age and goals. Bring a list of questions, and ask for the plan and fees in writing before you commit to anything.
