If a dentist has mentioned that you or your child has an overbite, or you’ve simply noticed your upper teeth sit noticeably further forward than your lower ones, you’re probably wondering what that actually means and what overbite treatment involves. The good news is that overbites are one of the most common and well-understood orthodontic issues out there, and there are more treatment paths available today than most people realize. 

What Is an Overbite, Exactly?

An overbite happens when your upper front teeth overlap your lower front teeth more than they should. A small amount of overlap is completely normal and necessary for healthy biting and chewing. It only becomes what’s called an overbite when that overlap goes beyond a typical range, sometimes referred to as a “deep bite” when it’s more pronounced.

Overbite vs Underbite: What’s the Difference?

These two terms get mixed up constantly, so it’s worth clearing up.

• Overbite means your upper teeth overlap your lower teeth vertically, more than normal. Your upper jaw and teeth sit further forward, or your lower jaw sits further back than they should.
• Underbite is essentially the opposite. Your lower teeth and jaw extend further forward than your upper teeth, so your lower jaw juts out.

There’s also a related term, “overjet,” which people sometimes confuse with overbite. Overjet refers to your upper teeth protruding horizontally out in front of your lower teeth (sometimes called “buck teeth”), while overbite is specifically about vertical overlap. You can have one, both, or neither, and your dentist can tell you exactly which applies to your bite.

Signs of an Overbite

Some overbites are obvious at a glance, while milder ones are easy to miss without a dental exam. Common signs include:

• Your upper front teeth noticeably cover your lower front teeth when you bite down
• Your lower teeth are barely visible, or not visible at all, when your mouth is closed
• Jaw pain, tightness, or clicking, particularly around your temporomandibular joint (TMJ)
• Difficulty or discomfort while chewing
• Speech that feels slightly affected, especially with certain sounds
• Uneven or accelerated wear on your teeth
• Frequent headaches, which can be related to bite misalignment and jaw strain
• In some cases, mouth breathing or snoring

If you’re not sure whether what you’re noticing qualifies as an overbite worth treating, that’s exactly what a dental exam is for. Not every overbite needs correction, but a proper assessment tells you whether yours does.

Why Overbites Happen

Some overbites are genetic, simply inherited jaw shape and tooth alignment passed down in families. Others develop from habits, particularly in childhood, including:

• Prolonged thumb-sucking or pacifier use past around age 3
• Tongue-thrusting, where the tongue pushes too far forward during swallowing
• Nail biting
• Teeth grinding or clenching (bruxism)
• Missing teeth that allow surrounding teeth to shift over time

Understanding the cause matters, since it can influence which treatment approach makes the most sense, especially for children who are still developing.

Overbite Treatment for Kids

Children have a significant advantage when it comes to overbite correction: their jawbones are still developing and are more responsive to gentle, guided movement. This is why early evaluation, generally recommended around ages 7 to 8, matters so much, since treatment during these growth years can sometimes address issues that would require more involved intervention later in life.

Common approaches for children include:

• Palatal expanders, which widen the upper jaw to create more space and improve how the upper and lower teeth align
• Braces, to guide teeth into proper position as they continue to erupt
• Headgear, used in some cases to help guide jaw growth
• Retainers, to hold results in place once active treatment is complete

Because a child’s bite is still developing, treatment often addresses the underlying jaw relationship, not just the visible position of the teeth, which can lead to more stable, long-lasting results. If you’re weighing whether braces make sense for your child right now, our guide on braces for kids in Vancouver walks through what an early evaluation actually involves and what signs to watch for.

Overbite Treatment for Adults

Adult jawbones have already finished growing, so treatment works a little differently, but effective options are still very much available.

• Traditional or clear braces, to gradually reposition teeth into better alignment
• Invisalign or other clear aligners, for many mild to moderate cases (more on this below)
• Tooth extraction, occasionally recommended to create more room for remaining teeth to align properly
• Corrective jaw surgery (orthognathic surgery), reserved for more severe cases where the underlying jaw structure, not just tooth position, needs to be addressed

Most adult overbites can be improved significantly with orthodontic treatment alone. Surgery tends to be reserved for cases where the jaw bones themselves are significantly misaligned, rather than the teeth alone.

Can Invisalign Fix an Overbite?

In many cases, yes. Invisalign has become increasingly capable of treating mild to moderate overbites, using a series of custom, clear aligners that gradually shift your teeth into better alignment, sometimes paired with small attachments or elastics to help guide the bite specifically.

That said, Invisalign isn’t the right fit for every overbite. More severe cases, particularly ones involving significant jaw misalignment rather than just tooth position, may respond better to traditional braces or, in the most severe cases, surgical correction. A consultation with your dentist is the best way to know whether Invisalign can realistically address your specific bite, or whether another approach would give you a better outcome.

What Happens If an Overbite Goes Untreated?

Not every overbite requires treatment, especially mild ones that aren’t causing any functional issues. But more significant, untreated overbites can lead to complications over time, including:

• Accelerated tooth wear and erosion
• Increased risk of cavities and gum disease, since misaligned teeth can be harder to clean effectively
• Chronic jaw pain or TMJ disorders
• Frequent headaches
• Speech difficulties
• In some cases, breathing issues

This is part of why an evaluation is worth doing even if your overbite doesn’t bother you day to day, since your dentist can tell you whether it’s something to simply monitor or something worth actively correcting.

What Determines the Cost of Overbite Treatment?

Overbite treatment cost varies significantly depending on a few factors:

• Severity of the overbite, since more significant misalignment typically requires longer, more involved treatment
• Treatment method, as Invisalign, traditional braces, and surgical correction all come with different cost structures
• Age, since childhood treatment sometimes (though not always) involves a different scope of care than adult treatment
• Length of treatment, which can range from several months to a few years depending on your specific case

Because pricing depends so much on your individual bite and the treatment path that fits it, the most accurate way to know your cost is a consultation, where your dentist can assess your bite and walk you through a realistic estimate and timeline.
