Just the mention of the word headgear might send shivers down the spines of many people who wore braces in their formative years. A headgear is worn around the head and face to help correct jaw alignment problems. You'd be excused for thinking that these devices -- which some might say resemble medieval instruments of torture with their straps, wires and metal bands -- were a relic of the '80s, but they're still around. Just hope that if your child's orthodontist prescribes one, your kid will only have to wear it at night and not (horrors!) to school every day. We sympathize, kids [source: Medicine Net].
