Answer First: Can Invisalign Fix Buck Teeth?
Yes, Invisalign can fix many cases of buck teeth. For most mild to moderate protruding front teeth, clear aligners gently shift the teeth into a healthier position over time. Severe cases involving the jawbone may need added support, which is why a personal evaluation matters.
Quick answer for Twin Falls patients
If your front teeth stick out and you want a discreet fix, Invisalign is often a strong option. At Advanced Dental Care of Twin Falls, Dr. Brian Rencher reviews your bite, spacing, and jaw position before recommending a plan. This makes sure the treatment fits your smile and not just a general rule.
When Invisalign is the right choice at Advanced Dental Care of Twin Falls
Invisalign works best when the protrusion comes from tooth position rather than a large jaw discrepancy. Aligners are clear, comfortable, and easy to fit into daily life. Research shows aligners can move teeth effectively for many common bite concerns, as noted in a systematic review comparing aligners with fixed appliances, which found aligners perform well for a range of everyday tooth movements.
What Are Buck Teeth?
Buck teeth are upper front teeth that protrude noticeably beyond the lower teeth. Dentists often describe this gap between the upper and lower front teeth as an overjet. A small overjet is normal, but a larger one can affect both appearance and function.
Defining protruding front teeth and overjet
Overjet measures how far the top front teeth extend forward past the bottom teeth. When this distance grows too large, the upper teeth look like they jut outward. This is what most people mean when they say buck teeth.
How buck teeth differ from a normal bite
In a healthy bite, the upper teeth rest just slightly ahead of the lower teeth with even contact. With buck teeth, that balance is off, and the front teeth carry more strain. The American Association of Orthodontists lists overjet among the common bite problems that can be corrected, and their guide helps explain why alignment affects daily comfort.
What Causes Buck Teeth?
Buck teeth are usually caused by genetics, jaw development, or long-term childhood habits. Often several factors combine. Understanding the cause helps guide the right correction.
Genetics and jaw development
Many people inherit the jaw shape or tooth size that leads to protruding front teeth. If a parent had buck teeth, a child may follow the same pattern. The way the upper and lower jaws grow also plays a large role.
Childhood habits: thumb-sucking and pacifier use
Thumb-sucking and extended pacifier use can push the front teeth forward while the mouth is still growing. When these habits continue past the toddler years, they can shape the position of the developing teeth and jaw.
Tongue thrusting and mouth breathing
Pressing the tongue against the front teeth when swallowing, known as tongue thrusting, can slowly push teeth outward. Chronic mouth breathing may also affect how the teeth and jaw settle over time.
Missing teeth, crowding, and spacing
Gaps from missing teeth, crowding, or uneven spacing can shift the front teeth into a forward position. When teeth do not have a stable place to sit, they may drift and create the appearance of buck teeth.
Why Correcting Buck Teeth Matters Beyond Appearance
Correcting buck teeth is about far more than looks. Protruding front teeth affect how you bite, chew, and protect your smile long-term. Fixing them supports comfort and lasting oral health.
Bite function and jaw comfort
When the front teeth stick out, the bite does not distribute pressure evenly. This can lead to jaw strain and uneven wear on certain teeth. Better alignment helps the bite work smoothly and comfortably.
Oral health and long-term well-being
Protruding front teeth are more exposed to injury and can be harder to clean, which raises the risk of decay and gum trouble. Good oral health also supports overall wellness, as explained in this overview of how oral health affects overall well-being, which connects a healthy mouth with confidence and quality of life.
A note from Dr. Brian Rencher“Buck teeth are rarely just a cosmetic concern. When I align protruding front teeth, patients often tell me their bite feels easier, and their confidence grows. That combination is the real reward of treatment.” |
How Invisalign Corrects Buck Teeth
Invisalign corrects buck teeth by using a series of clear, custom aligners that gradually guide protruding front teeth into a better position. Each set makes a small, planned adjustment until the teeth reach their goal.
How clear aligners move protruding teeth
Every aligner applies gentle, steady pressure to the teeth that need to move. Over the course of treatment, the front teeth are eased back into alignment. This slow and controlled approach is comfortable for most patients.
How Invisalign compares to fixed braces
Invisalign is clear and low-profile, while traditional braces use metal brackets and wires. For many everyday cases, aligners deliver strong results, and a review of clear aligner treatment highlights how the technology has grown to handle a wider range of tooth movements than in earlier years.

Dr. Brian Rencher’s approach at Advanced Dental Care of Twin Falls
Dr. Brian Rencher builds each plan around your unique bite and goals. At Advanced Dental Care of Twin Falls, he uses digital scans to map the exact movements your teeth need. You can also read more about how Invisalign fixes upper teeth crowding to see how alignment ties into overall bite health.
What Invisalign Can and Cannot Fix
Invisalign can fix many mild to moderate cases of buck teeth, but very severe jaw-based cases may need more. Knowing where aligners fit best helps set the right expectations.
Mild to moderate overjet cases
When protruding front teeth come mainly from tooth position, Invisalign is often an excellent match. These cases usually respond well and produce a smooth, natural-looking result.
Severe skeletal cases that may need more
When buck teeth are driven by a large jaw difference, aligners alone may not fully resolve the concern. In those situations, additional treatment may be recommended alongside or instead of Invisalign.
Why a professional evaluation matters
A hands-on evaluation is the only reliable way to know what your smile needs. Dr. Brian Rencher examines your bite, teeth, and jaw before recommending a path. To learn why so many patients choose aligners, see why Invisalign is the most loved smile makeover today.

Meet Dr. Brian Rencher
For Dr. Brian Rencher, dentistry runs in the family. A Twin Falls native, he practiced alongside his father for 18 years before his father’s retirement in 2019, and he’s carried that same commitment to patient care forward ever since. Today he brings his expertise in cosmetic dentistry, Invisalign, and implants to every visit, always with a personal touch.
His path took him through Idaho State University for his bachelor’s degree and the University of Louisville for his Doctorate in Dental Medicine. Along the way, he served an LDS mission in Chile and came home fluent in Spanish, a skill he still uses to connect with patients today. He and his wife, Jodie, married in 1995 and now have four kids: Madison, Dalton, Meigan, and Meilin.
In 2024, Dr. Rencher was named an AACA Fellow, an honor held by fewer than 100 dentists worldwide. He’s also led humanitarian dental trips abroad and volunteers with Special Olympics, Give Kids a Smile, and Boy Scouts of America. Through Dentistry from the Heart, he and his team provide thousands of dollars in free dental care to the local community.
Outside the practice, he’s usually outdoors: skiing, playing soccer, boating, or spending time with his kids. That same energy shows up in the practice he and Jodie have built, one where patients and team members feel right at home.
Frequently asked questions
| Q: Will Invisalign fix my buck teeth? In many cases, yes. Invisalign works well for mild to moderate protruding front teeth by gently shifting them into better alignment. A personal evaluation with Dr. Brian Rencher at Advanced Dental Care of Twin Falls confirms whether it is the right fit for you. |
| Q: What teeth can Invisalign not fix? Invisalign may not fully correct very severe cases that stem from a large jaw difference rather than tooth position. Some complex bite concerns may need added treatment. An in-person exam is the only reliable way to know what your smile requires. |
| Q: What’s the worst teeth Invisalign can fix? Invisalign handles a broad range of concerns, including many moderate overjet, crowding, and spacing cases. The more severe the jaw involvement, the more likely additional support is needed. Dr. Brian Rencher can review your case and explain your options clearly. |
| Q: Why do dentists not recommend Invisalign? Dentists may suggest another option when a case involves a significant jaw discrepancy that aligners alone cannot address. This is not a fault of Invisalign but a matter of matching treatment to the concern, which is why an evaluation is so important. |
| Q: How long does Invisalign take to fix buck teeth? Timelines vary based on how much the teeth need to move and how consistently you wear the aligners. Wearing them 24 hours a day supports the best progress. Dr. Brian Rencher will share a personalized estimate after your consultation in Twin Falls. |
Remember: Every smile is different, so only a personal evaluation can confirm the right plan for your buck teeth.
