How Can You Fix An Underbite? | Braces And Surgery Options

Fixing an underbite usually starts with an orthodontic exam, then braces or aligners, and sometimes jaw surgery.

An underbite means your lower teeth sit in front of your upper teeth when you bite down. Some are mainly tooth position. Some come from jaw growth. If you’re asking “how can you fix an underbite?”, the fix depends on which one you’ve got.

Start with a bite check today. Once you know if it’s teeth, jaw, or both, the next steps stop feeling like a guessing game.

Get a bite check — A dentist or orthodontist can map what’s driving the underbite.
Move teeth into place — Braces or clear aligners can correct many dental underbites.
Guide growth early — In kids, appliances can steer how jaws and teeth line up.
Lock in the result — Retainers keep teeth from sliding back after treatment.

What An Underbite Is And Why It Happens

Underbite is often labeled “Class III.” The lower jaw sits forward, the upper jaw sits back, or the teeth tilt in a way that makes the lower teeth win the race to the front. That detail changes everything, since braces move teeth, not jaw bones.

Clinicians may also talk about “reverse overjet,” meaning the lower front teeth sit ahead of the upper front teeth. A small reverse overjet can come from crowding or early tooth loss. A larger one often points to jaw growth patterns.

Common Causes That Show Up In A Bite Check

Jaw growth patterns — Family traits can affect jaw size and position.
Tooth crowding — Tight spacing can push teeth into a crossbite.
Childhood habits — Thumb sucking or long pacifier use can change tooth tilt.
Mouth posture — Ongoing open-mouth posture can change how teeth meet.

Signs That Point To An Underbite

An underbite can be obvious in the mirror. Other times, it shows up as a pattern: chewing feels off, speech sounds change, or front teeth wear faster than you’d expect.

Check the front bite — Lower front teeth sit in front of upper front teeth when you close.
Notice uneven chewing — You favor one side or avoid biting with front teeth.
Watch tooth wear — Chips, flattening, or sensitivity show up on front teeth.
Pay attention to jaw strain — Tired jaw muscles, soreness, or clicking can appear.

How An Orthodontist Checks Your Bite

A good plan starts with a clear snapshot of your bite. That means a hands-on check plus records that show tooth position, jaw position, and how your teeth touch when you close. Many offices use digital scans, so the process is quick.

You’ll hear “skeletal” and “dental.” Skeletal means jaw position is the main driver. Dental means tooth position is the main driver. Lots of people land in the middle.

What The Record Set Often Includes

Do a bite check — The clinician checks how teeth touch in front and back.
Scan or mold teeth — A 3D record shows crowding and tooth tilt.
Take photos — Face and smile photos show how lips and teeth line up.
Get X-rays — Images show roots and jaw position from more than one angle.

Questions Worth Asking At The First Visit

Ask what’s driving it — Teeth, jaw, or a mix changes the plan.
Ask what will change — Find out what each option can fix in your bite.
Ask about daily effort — Elastics and aligner wear can make or break results.
Ask about retention — Get a clear plan for retainers and follow-up visits.

Bring past X-rays or dental notes if you have them.

How To Fix An Underbite With Braces, Aligners, Or Surgery

Underbite treatment is a set of choices. Braces and aligners move teeth. Childhood appliances can guide growth. Surgery moves jaw bones when the mismatch is too large for tooth movement alone. Many plans mix methods, since teeth still need time to settle into a new bite.

Two plain-language references that explain bite problems and orthodontic treatment are MedlinePlus on malocclusion and the NHS orthodontic treatment page. Your own records decide which option fits you.

Approach	What It Changes	Best Fit
Braces + elastics	Moves teeth and guides the bite	Mild to moderate underbite
Clear aligners + elastics	Moves teeth with removable trays	Dental underbite with steady wear
Growth appliance	Guides jaw growth in childhood	Early jaw mismatch in kids
Tooth removal + orthodontics	Makes room to shift teeth back	Crowding with tooth-driven underbite
Jaw surgery + orthodontics	Moves the jaw bones into place	Jaw-driven underbite in adults

Braces With Elastics

Braces move teeth with brackets and wires. Elastics add pull between the top and bottom teeth so the bite can settle into a new fit. With an underbite, elastics may guide the upper teeth forward, the lower teeth back, or both.

Wear elastics as told — Skipped days can leave the bite half-fixed.
Keep cleaning strict — Brackets trap plaque, so brushing needs extra care.
Show up for adjustments — Visits catch loose parts and keep movement steady.

Clear Aligners

Aligners can treat some underbites, mainly when tooth position is the driver. They depend on wear time and a clean fit. If trays aren’t worn most hours, teeth won’t track, and the bite won’t settle the way the plan expects.

Wear trays most hours — Consistent wear keeps each tray doing its job.
Use attachments — Small bumps help trays grip and move teeth on target.
Change trays on schedule — Moving too fast can irritate gums and stall progress.

When Surgery Enters The Plan

Surgery is used when jaw position drives the underbite and tooth movement alone can’t create a stable bite. Many people do braces first, then surgery, then finish with orthodontics once healing is underway.

Confirm the jaw mismatch — Imaging and bite records show what needs to move.
Line up teeth pre-op — Teeth are placed so they fit once jaws are repositioned.
Finish the bite after — Orthodontics fine-tunes how teeth meet after healing.

Fixing An Underbite In Kids And Teens

Kids and teens have an advantage: growth is still happening. When a jaw mismatch is found early, appliances can widen a narrow upper jaw or guide jaw growth. That can reduce the underbite later, even if full braces are still needed in the teen years.

Early care isn’t a race to braces. It’s a way to catch patterns that tend to get tougher with age and to use light forces while bones are still changing shape.

Widen the upper jaw — An expander can correct a crossbite and make room for teeth.
Guide forward growth — Some kids benefit from a facemask style appliance.
Keep space open — Space maintainers can stop drifting after early tooth loss.
Build brushing habits — Appliance care is a daily job, so routines matter.

Fixing An Underbite In Adults

Adults can still fix an underbite, yet jaw bones aren’t growing. If the underbite is dental, braces or aligners can move teeth into a better fit. If it’s jaw-driven, orthodontics can still help tooth position, though surgery may be the only way to move the jaw.

Some adult plans use tooth “camouflage,” meaning teeth are moved to mask a jaw mismatch. It can improve function in certain bites, yet it has limits. The goal is a stable bite that feels good when you chew.

Pick braces for control — Braces handle tougher tooth moves and bite settling.
Pick aligners for flexibility — Trays suit people who can wear them as planned.
Plan gum care early — Healthy gums make tooth movement safer and smoother.
Ask about long-term wear — Retainers keep hard-won changes from drifting.

Surgery, Recovery, And Aftercare Basics

If jaw surgery is part of your plan, expect a staged process. Braces often start first, surgery follows, then orthodontics finishes the bite. The full timeline differs by case, yet the flow is similar.

What The Usual Timeline Looks Like

Do planning visits — Scans and measurements map where the jaws should land.
Prepare with braces — Teeth are set up to fit after the jaw change.
Have surgery — The jaws are repositioned and held with plates and screws.
Heal and settle — Soft foods, follow-ups, and time allow swelling to drop.

Recovery often includes swelling, tightness, and numb patches early on. Plan meals, rides, and time off work or school before surgery day so you can rest without scrambling.

Ask your surgeon about risks like infection, bleeding, feeling changes, and bite relapse. Hearing them in plain terms can help you decide with a clear head.

Costs, Timing, And Everyday Practicalities

Underbite treatment takes time. Braces or aligners can run for many months. A surgery plan can run longer, since orthodontics may start before surgery and finish after. Retainers follow all of it.

Insurance rules vary. Dental plans may pay for part of orthodontics for kids, while adult orthodontics may be limited. If surgery is done for function, some medical plans may pay for part of the hospital and surgical fees. Ask for a written estimate and ask which parts go to dental insurance and which go to medical insurance.

Ways To Keep Treatment Moving

Wear elastics daily — Skipped wear can drag treatment out and leave the bite uneven.
Protect teeth at night — A guard may help if you grind during sleep.
Follow retainer rules — Retainers hold tooth position while bone tightens.

If you’re still stuck on the next step, ask the office to spell out the goal in one sentence. You want a bite that fits, stays stable, and is easy to keep clean. A clear target makes day-to-day choices easier, from elastic wear to retainer habits.

Frequently Asked Questions

Can you fix an underbite without braces?

In most cases, no. Cosmetic dental work can change how teeth look, yet it won’t change how teeth meet under pressure. If your underbite is mild and tooth-driven, clear aligners may replace braces. If jaw position drives it, orthodontics alone may not create a stable bite.

Do jaw exercises fix an underbite?

Exercises can help with muscle tension and jaw joint comfort. They don’t move teeth through bone or shift jaw bones into a new position. If you have jaw pain, ask a clinician to check your bite first. Grinding and clenching can mimic bite trouble.

What if my underbite is only on one side?

A one-sided underbite can come from a crossbite or a slide where the jaw shifts as you close. Scans can show whether it’s tooth position, jaw position, or a closing habit. Fixing it sooner can reduce uneven wear and gum stress on that side.

Will insurance pay for underbite treatment?

Coverage depends on your plan and your age. Many dental plans treat orthodontics as a separate benefit with limits or waiting periods. If jaw surgery is tied to function, a medical plan may cover part of the hospital and surgical fees. Ask the office for codes so you can check benefits in writing.

How do you keep an underbite from coming back?

Retention is the long game. Wear retainers on the schedule you’re given, even after teeth feel stable. If you grind at night, a guard can protect teeth and cut bite changes from wear. Keep dental checkups, since small shifts are easier to correct early than after years.

Wrapping It Up – How Can You Fix An Underbite?

Fixing an underbite starts with a bite check that sorts tooth issues from jaw issues. From there, braces, aligners, growth appliances, and surgery each have a place. The right pick is the one that gives you a stable bite you can live with long term.

If you’re still stuck, book a visit and bring your questions. Ask what will change, how long it may take, and how retention will work. A clear plan beats guessing and keeps you from burning time on fixes that can’t move the cause.
