Orthodontic headgear is an appliance worn partly outside the mouth that applies gentle force to guide the growth of the upper jaw or to anchor the back teeth, and it is used mostly in growing children and teenagers. It looks dramatic, but its job is simple: to use a child's natural growth to correct the way the upper and lower jaws meet. Because it relies on growth, timing and consistent wear matter more than almost anything else.
Key takeaways
- Headgear uses gentle force from outside the mouth to guide upper jaw growth or to reinforce anchorage.
- It works best in growing children, because it relies on natural growth still being available.
- The result depends heavily on wearing it for the prescribed hours, usually 10 to 14 hours a day.
- It is generally worn at home and overnight, not at school, and is one tool among several for correcting a bite.
The one thing that decides success: wear time
If there is a single rule with headgear, it is that it only works if it is worn. Most plans ask for somewhere between 10 and 14 hours a day, which usually means evenings and overnight. Worn consistently, it can produce a real orthopaedic effect on a growing jaw. Worn sporadically, it does little, and treatment stalls. This is why headgear suits motivated families and why your orthodontist will track the hours closely.
How headgear works
The upper jaw, or maxilla, is still growing in children. Headgear attaches to the upper teeth or braces with a facebow and is held by a strap around the neck or head, applying a light backward or upward force. This can slow the forward growth of the upper jaw so the lower jaw can catch up, move upper back teeth backwards to make space, or stop those teeth drifting forward while other teeth are aligned (called anchorage). It is most often used for an overbite or crowded upper teeth in a growing child.
The main types
| Type | How it pulls | Often used for |
|---|---|---|
| Cervical (neck strap) | Backward and slightly down from the neck | Overbite, moving upper back teeth back |
| High-pull | Backward and up from the top of the head | Overbite with a long face pattern |
| Combination | Both directions together | Balanced control of the upper teeth |
| Reverse-pull (facemask) | Forward, to bring the upper jaw ahead | Underbite where the upper jaw is behind |
The reverse-pull facemask is worth a special mention, because it does the opposite job: in a young child with an underbite, it gently encourages the upper jaw forward. The other types mostly restrain or reposition the upper teeth and jaw.
When is the right age?
Because headgear depends on growth, it is generally used in the late primary and early teenage years, around the time of the growth spurt, and before growth finishes. Used too late, when growth has slowed, the orthopaedic effect is limited and other approaches may be needed. This is part of why orthodontists assess children early. Headgear is often one stage in a wider plan that may include braces afterwards, similar to how a twin block or a Herbst appliance is used to guide jaw growth before fixed braces.
Is headgear still used?
Headgear is used less commonly than it once was, because fixed functional appliances, temporary anchorage devices (small bone screws), and other tools can now achieve some of the same goals with less reliance on a child wearing an external appliance. It remains a well-evidenced and effective option, particularly for genuine orthopaedic restraint of the upper jaw, and many orthodontists still reach for it in the right case. The best appliance is the one that suits the specific problem, not the newest one.
Living with headgear
Headgear is removable and is worn at home and overnight, not during school or sport. There can be mild tenderness for a day or two after each adjustment, which settles. Safety catches and snap-release straps reduce the small risk of injury, and children are taught to put it on and take it off carefully. Eating, brushing, and playing happen with it removed, so daily life is largely normal.
General cost and what to expect
Headgear is usually part of a broader orthodontic plan rather than a standalone fee, and total orthodontic costs vary with the complexity and length of treatment. We do not list our own prices here.

Frequently asked questions
Does headgear hurt?
It should not hurt when worn correctly. Mild tenderness for a day or two after an adjustment is normal and settles with time and simple pain relief if needed.
How many hours a day does my child wear it?
Most plans ask for 10 to 14 hours a day, usually after school and overnight. Consistent wear is what makes it work, so the prescribed hours matter.
Can adults use headgear?
Headgear relies on jaw growth, so its orthopaedic effect is limited in adults. Adults with similar problems are usually treated with other approaches, sometimes including surgery for severe jaw differences.
Will my child wear it to school?
No. It is worn at home and overnight, not at school or during sport, which makes it more manageable socially than many families expect.
Is headgear outdated?
It is used less than in the past because of newer alternatives, but it is still effective and appropriate in selected cases, especially for true upper-jaw restraint in a growing child.
When to see a dentist
If your child has a noticeable overbite, underbite, or crowding, an early orthodontic assessment will show whether headgear or another approach suits, and growth timing makes early advice valuable.
