If your bottom teeth sit in front of your upper teeth when you close your mouth, you’ve got an underbite. And yes, you’ve probably Googled it at least 3 times already. The short answer: Invisalign can fix an underbite — but the longer answer matters a lot more, because it depends entirely on why your bite is off and how severe it is. Here’s everything you need to know before booking a consultation at Apple Tree Dental in London, Ontario.
Quick Answer: Can Invisalign Fix an Underbite?
- Yes, Invisalign clear aligners can fix mild to moderate underbites by gradually repositioning teeth into proper alignment.
- Severe underbites caused by jaw structure may require braces, jaw surgery, or a combination approach.
- Treatment typically takes 6–18 months depending on the severity of your case.
- Aligners must be worn 20–22 hours per day for consistent, predictable results.
- A professional bite evaluation at Apple Tree Dental’s orthodontic team is the only way to confirm which treatment fits your underbite.
What Exactly Is an Underbite?
An underbite, technically called a Class III malocclusion, is when your lower jaw or lower teeth protrude further forward than your upper teeth. In a healthy bite, the upper teeth sit slightly over the lower ones.
Underbites aren’t just a cosmetic issue. They can cause uneven tooth wear, jaw pain, difficulty chewing, and in some cases, speech problems. So treating one isn’t vanity — it’s practical oral health care. According to the Canadian Dental Association, untreated bite misalignments compound over time, making early intervention the most cost-effective path.
Underbite vs overbite: quick distinction
A lot of people mix these up, which is fair. Understanding underbite vs overbite helps clarify what you’re actually dealing with:
- Normal bite: Upper teeth sit slightly over lower teeth
- Overbite: Upper teeth overlap lower teeth excessively in a vertical direction
- Underbite: Lower teeth protrude in front of upper teeth horizontally
If you’re unsure which one you have, a dentist can tell you in about 30 seconds.
Types of underbite
- Dental underbite — the jaw is fine, the teeth are just positioned wrong. Responds well to Invisalign or braces.
- Skeletal underbite — the lower jaw itself has grown too far forward. Mild cases can sometimes be managed with orthodontics alone, but severe ones often need jaw surgery.
- Functional underbite — caused by childhood habits like thumb-sucking, tongue thrusting, or prolonged pacifier use. Mild-to-moderate cases often respond well to clear aligners.
Knowing which type you have is the first conversation to have with your dentist.
Why London, Ontario patients should treat an underbite early
Common risks of leaving an underbite untreated include:
- Jaw discomfort and TMJ stress
- Difficulty chewing or speaking clearly
- Uneven and accelerated tooth wear
- Long-term oral health complications that become more expensive to fix
Can Invisalign Fix Underbite in London, Ontario?
Yes — for the right candidate. At Apple Tree Dental in London, Ontario, Invisalign is used as a proven orthodontic treatment for underbite in patients with dental — rather than skeletal — bite issues. Clear aligners gradually shift teeth into more favorable positions using a series of custom-made trays, with each one applying controlled pressure to guide teeth toward improved alignment.
When Invisalign works best
Invisalign clear aligners are ideal if:
- Your underbite is mild to moderate in severity
- The issue is dental, not skeletal in origin
- You are committed to wearing aligners consistently (20–22 hours per day)
How Invisalign corrects your bite
The process begins with advanced 3D scans that map tooth movement step-by-step, allowing the dental team to visualize how the bite will change throughout treatment. Apple Tree Dental maps your tooth movements before a single aligner is made — giving patients in London, Ontario a clear picture of their expected outcome from day one. The treatment works by:
- Gradually shifting lower teeth backward into proper position
- Moving upper teeth forward to close the gap
- Using small tooth-colored attachments or elastics in some cases to guide complex movements
Each aligner is worn for roughly 1–2 weeks. That 20–22 hour daily wear rule isn’t optional — wear them less, and your treatment stretches out (and your costs can too). On average, treatment lasts 12–18 months, although many patients start noticing changes within the first few weeks.
When Invisalign Alone May Not Work
If your underbite is caused by a structural jaw issue rather than tooth positioning, aligners alone won’t fully correct it. The American Association of Orthodontists notes that skeletal bite issues often require more advanced correction beyond clear aligners. In those cases, a more involved plan is needed.
You may need:
- Traditional braces — for moderate to severe dental underbites requiring more mechanical control
- Orthognathic (jaw) surgery — for severe skeletal misalignment where the jaw itself needs repositioning
- Combination treatment — aligners or braces paired with elastics or surgical preparation
Your Apple Tree Dental orthodontic consultation will determine exactly which path is right for your specific bite.
Invisalign vs Braces for Underbite
A common question from London, Ontario patients: “Do braces fix underbite better than Invisalign?” The honest answer depends on severity. Braces are fixed to your teeth — they work 24/7 without any compliance requirement. For patients who know they’ll forget to put aligners back in after lunch, braces are genuinely worth considering. Here’s how both options compare:
| Feature | Invisalign | Braces |
|---|---|---|
| Appearance | Clear, nearly invisible | Visible brackets & wires |
| Comfort | Smooth removable aligners | Fixed with brackets & wires |
| Best for | Mild to moderate cases | Moderate to severe cases |
| Compliance required | Yes — 20–22 hrs/day | No — fixed throughout |
| Lifestyle | Removable for eating & cleaning | Fixed throughout treatment |
| Treatment time | 12–18 months (typical) | 1–2 years (typical) |
For younger children aged 6–10, a palate expander may come before either option — it guides the upper jaw forward while it’s still developing. Apple Tree Dental offers both Invisalign and braces, and will recommend the most effective treatment based on your clinical assessment.
Severe Underbite Treatment: What Happens When Invisalign Isn’t Enough?
For a severe underbite, orthodontics alone sometimes can’t get the job done. In these cases, orthognathic surgery (jaw surgery) may be recommended. It repositions the lower jaw, upper jaw, or both. It sounds dramatic, but it’s a well-established procedure with strong outcomes for patients who need it.
Surgery is typically combined with orthodontic treatment: braces or Invisalign before surgery to align the teeth, then surgery to correct the jaw, then more orthodontics to fine-tune the result. According to the Canadian Dental Association’s treatment guidelines, a thorough clinical evaluation determines whether non-surgical treatment is a viable option for each patient.
If you’re in this category, your dentist will refer you to an oral and maxillofacial surgeon. The important thing is getting an accurate diagnosis first.

Frequently Asked Questions: Can Invisalign Fix Underbite?
Can Invisalign fix underbite completely?
Yes, for mild to moderate cases caused by tooth positioning. Severe underbites involving the jaw structure may require surgery or combination treatment. A clinical assessment at Apple Tree Dental will confirm which category your case falls into.
How long does Invisalign take for underbite correction?
Typically 6–18 months depending on the severity of misalignment and how consistently aligners are worn. Mild cases often see results within 6–12 months. More complex cases can extend beyond 18 months.
Is Invisalign better than braces for underbite?
Invisalign is more comfortable and nearly invisible, making it the preferred choice for mild to moderate cases. Braces provide more controlled force and are better suited for complex or severe underbites. Your dentist will recommend the right fit based on your specific bite.
Can adults in London use Invisalign for underbite?
Yes. Invisalign works for both teens and adults and is available to patients of all ages at Apple Tree Dental in London, Ontario. The main difference is that jaw growth is complete in adults, so severely skeletal underbites are more likely to need surgical correction.
Does Invisalign move the jaw?
No. Invisalign primarily moves teeth. If jaw correction is needed, additional treatment such as orthognathic surgery may be required alongside or after aligner therapy.
How do you fix a mild underbite without surgery?
A mild underbite can often be corrected with Invisalign or braces alone. Elastics may be added to assist with bite adjustment. Surgery is generally reserved for severe skeletal cases only.
What is the difference between an underbite and an overbite?
In a normal bite, upper teeth slightly overlap lower teeth. An overbite means the upper teeth overlap excessively. An underbite is the opposite — the lower teeth protrude in front of the upper teeth when the mouth is closed.
Is underbite treatment covered by dental insurance in Ontario?
Many Ontario dental plans cover a portion of orthodontic treatment, including Invisalign and braces. Coverage amounts vary by plan. The best way to know exactly what you’re covered for is to contact Apple Tree Dental directly — the team can help you understand your benefits before committing to anything.
