For children and teens with a significant overbite, an orthodontist may recommend a Herbst appliance or a similar bite corrector. These devices do something braces alone cannot: they help guide jaw growth. Here is how they work and what to expect.
What is a Herbst appliance?
A Herbst appliance is a fixed device that gently encourages the lower jaw to grow into a better position relative to the upper jaw. It uses a small telescoping arm on each side that connects the upper and lower teeth, holding the lower jaw slightly forward. Over months, this helps correct an overbite where the lower jaw sits too far back.
Why timing matters
Bite correctors are most effective while a child is still growing, which is why early evaluation is so valuable. Guiding growth at the right age can reduce the severity of a bite problem and, in some cases, help a patient avoid more involved treatment later.

What to expect
- Placement: The appliance is attached to the teeth and is not removable, so there is nothing to lose or forget to wear.
- Adjustment period: Speaking and eating feel different for the first several days, then become comfortable.
- Care: Avoid hard and sticky foods, and keep the appliance clean with thorough brushing.
- Duration: A Herbst is typically worn for several months and is often used alongside or before braces.
Other bite-correcting appliances
Depending on the case, your orthodontist might use a different functional appliance or pair treatment with a palatal expander to create room and balance the bite.
Frequently asked questions
Does a Herbst appliance hurt?
There may be mild soreness and a short adjustment period, but it should not be painful once you get used to it.
Can adults use a Herbst appliance?
Herbst appliances work best in growing patients. Adults with jaw discrepancies may need different approaches, which an orthodontist can explain.
Will my child still need braces?
Often yes. Bite correctors fix jaw alignment, while braces or aligners finish straightening the teeth.
