Aside from the obvious benefits of orthodontic treatment, like increased confidence and ease of hygiene, another benefit is not so obvious: improved jaw function. If your child has an overbite, simple treatment with braces will not correct the problem. The Herbst appliance, usually in conjunction with braces, is used to help the lower jaw develop in a forward direction. This eventually leads to an ideal bite. Left untreated, an improper bite may threaten the long-term health of your child's teeth, gums, and jaw.
A Herbst appliance is fixed to your child's molars. It includes a metal tube that connects the upper and lower jaw. By adjusting the tube, your orthodontist is able to control the jaw's position in relation to the upper teeth.
Herbst vs. Headgear for an overbite
We do not use headgears in our office to treat overbites and here are some of the differences between a Herbst and a Headgear. The main difference is that the Herbst appliance is securely fastened to your child's teeth inside their mouth, while a headgear is removable and is worn outside of the mouth. To be truly effective, a headgear must be worn between 12 and 16 hours per day, which often poses a problem with patients. Since the Herbst appliance is not removable, you won't need to keep track of how many hours per day your child wears it.
Another difference is aesthetics. A headgear is bulky, made of metal hooks or a facebow, and straps or a head cap to anchor the headgear to the back of the head or neck. A Herbst appliance is a much more discreet option: it may be visible when your child laughs or speaks, but it is inside the mouth unlike the Headgear which is worn outside of the mouth.
Adjusting to a Herbst Appliance
Muscle Tenderness – When your child first gets his or her herbst appliance, there may be some overall muscle tenderness and soreness of the teeth. As your child's mouth adapts to the appliance, the soreness should fade.
Tissue Irritation – Because the Herbst appliance is metal, it may cause some slight tissue irritation, especially on the lower gums. It will take time for your child's mouth to adapt. Until it does, dental wax can help to ease the irritation.
Diet – Eating softer food will help with any muscle soreness, especially after the first week or two after getting the appliance. It is also important to eliminate sticky foods, like candy and gum, or hard, crunchy food, which can damage the appliance and lengthen treatment time.
