Headgear is usually advised for youngsters whose jaw bones are still developing. Headgear, unlike braces, is worn partially outside the mouth. If your child's bite is badly misaligned, an orthodontist may suggest headgear. A malocclusion is a misaligned bite. It can cause pain when chewing certain foods like nuts and hard candy. An orthodontist will also advise headgear if you're seeking to improve the appearance of teeth that have been damaged by decay or injury. Youngsters who need headgear but don't wear it all the time should be fitted with a chin strap. This helps prevent them from swallowing their tongue or cheek while they sleep. The best time to start wearing headgear is when your child is between the ages of 7 and 10 years old. However, some children may benefit from headgear earlier or later in life depending on how quickly their jaws grow and remodel once they stop wearing the device. Headgear is not necessary for every child undergoing orthodontic treatment. Your dentist will take x-rays and talk with you about your child's development before determining whether or not headgear is appropriate. If your dentist does recommend headgear, he or she will help select a product that fits properly and doesn't interfere with your child's ability to eat food comfortably.
