Fixing an overbite with braces typically takes 12 to 36 months, depending on how far your upper teeth overlap your lower teeth. A mild overbite can be corrected in about 12 to 18 months, while severe cases may require two to three years of active treatment.
Timeline by Overbite Severity
The single biggest factor in how long you’ll wear braces is the size of the overbite itself. Orthodontists generally classify overbites into three categories, each with a different expected timeline:
- Mild overbite: 12 to 18 months. The upper front teeth overlap the lower teeth slightly more than normal, but the jaw alignment is mostly fine.
- Moderate overbite: 18 to 24 months. There’s a more noticeable overlap, and the bite may be affecting how the teeth wear against each other.
- Severe overbite: 24 to 36 months or longer. The upper teeth significantly cover the lower teeth, and the underlying jaw position is often part of the problem.
These ranges assume treatment with traditional metal or ceramic braces. If your overbite comes with additional issues like crowding, gaps, or crossbites on the sides, expect the timeline to push toward the longer end of each range.
What Makes Treatment Take Longer
Severity isn’t the only variable. Several other factors can add months to your treatment.
Age plays a meaningful role. In adolescents, the jawbone is still growing, which makes it easier to guide into the correct position. Adult jaws are fully set, so moving teeth through mature bone takes more time and more force. A moderate overbite that resolves in 18 months for a teenager might take closer to 24 months for an adult.
The type of overbite also matters. A dental overbite, where only the teeth are angled too far forward, is simpler to fix than a skeletal overbite, where the upper jaw itself is positioned ahead of the lower jaw. Skeletal overbites often require additional appliances or, in severe adult cases, jaw surgery, both of which extend the overall timeline significantly.
Compliance is the factor you can actually control. Wearing rubber bands exactly as directed, keeping your scheduled adjustment appointments, and avoiding foods that break brackets all help keep treatment on track. A broken bracket can add weeks. Inconsistent elastic wear can stall progress for months.
Rubber Bands and Additional Appliances
Braces alone straighten teeth, but correcting an overbite usually requires extra tools to shift the jaw relationship. The most common are rubber bands (elastics) that hook from the upper teeth to the lower teeth, pulling the lower jaw forward or guiding the upper teeth back. You’ll typically wear these for several months to a full year during the middle portion of treatment.
For growing patients with a significant skeletal overbite, orthodontists sometimes use a fixed appliance that connects the upper and lower jaws internally, encouraging the lower jaw to grow forward. Kids usually wear this type of device for about 12 months before transitioning to braces alone to finish aligning the teeth. This phase adds time on top of the braces phase, though there’s often overlap.
Clear Aligners vs. Traditional Braces
Clear aligners can correct mild overbites and may even finish slightly faster than braces in straightforward cases, sometimes in as little as 6 to 12 months. For moderate to severe overbites, though, traditional braces are generally more effective because they allow the orthodontist to make precise adjustments that aligners can’t replicate as easily. That’s especially true when rubber bands or auxiliary appliances are needed to reposition the jaw.
If speed is a priority and your overbite is mild, aligners are worth discussing with your orthodontist. For anything beyond mild, braces tend to deliver a more predictable result, even if they take a bit longer.
When Jaw Surgery Is Needed
A small percentage of severe overbites in adults can’t be fully corrected with braces alone because the problem is in the bone, not just the teeth. In these cases, the treatment plan combines orthodontics with jaw surgery, and the total process spans two to three years. You’d typically wear braces for several months before surgery to position the teeth, undergo the surgical correction, then continue in braces for another six to nine months afterward to fine-tune the bite. It’s a longer road, but it’s the only way to correct a large skeletal discrepancy once the jaw has stopped growing.
What Happens After Braces Come Off
Getting the braces removed isn’t the end of the process. Without a retainer, teeth will gradually drift back toward their original position, and overbites are particularly prone to relapse. Most orthodontists prescribe a removable retainer worn full-time for four months to a year after braces. After that initial period, you’ll likely transition to nighttime-only wear, potentially for several years or indefinitely.
A fixed retainer, which is a thin wire bonded behind your front teeth, is another option. It stays in place for years and requires no daily effort on your part, though it does make flossing a bit more involved. Either way, the retention phase is what protects the investment you made during the active treatment months.
