Breaking the Habit
Like many potentially harmful behavior patterns, thumb sucking can be a difficult habit to break. Through the years, parents have tried a variety of home remedies, such as having the child wear gloves, coating the digits with a bitter-tasting substance — and even reasoning with their toddlers. Sometimes it works — but in other cases, the allure of thumb sucking proves very difficult to control.
If your child has a thumb or finger sucking habit that has persisted past the age of three, and you've been unable to tame it, then it may be time for you to visit our office. We will consider treating your child with a "habit appliance" such as a fixed palatal crib or a removable device. This crib isn't for sleeping — it's a small metal appliance worn inside the mouth, attached to the upper teeth.
How does it work? The semicircular wires of a palatal crib keep the thumb or finger from touching the gums behind the front teeth. Simply preventing this contact seems to take all the enjoyment away from the thumb sucking habit — and without that pleasurable feedback, a child has no reason to continue the behavior. In fact, the device is often successful the first day it's worn.
Using a Habit Appliance
If your child could benefit from a habit appliance, the first step is to get a thorough examination, which may include taking X-rays, photographs and dental impressions. If it's recommended, a crib will then be custom-fabricated to fit your child's mouth, and placed at a subsequent appointment. Afterwards, your child will be periodically monitored until the appliance is removed — typically, a period of months.
Although wearing the crib isn't painful, your child may experience some soreness in the upper back teeth for a few hours after it's first installed. He or she may also have a little trouble falling asleep for a day or two afterward. Plenty of extra attention and TLC are usually all that's needed to make everything all right. While the appliance is being worn, it's best to avoid chewing gum and eating hard, sticky food that might cause it to come loose.
A Word About Tongue Thrusting
Like thumb sucking, tongue thrusting is a normal behavioral pattern in young children. It's actually part of the natural infantile swallowing pattern, which will normally change on its own — by the age of 4, in most children. If the pattern doesn't change, however, it can lead to problems similar to those caused by thumb sucking: namely, problems with tooth alignment and skeletal development. Fortunately, this problem can be successfully treated with a habit appliance that's very similar to a fixed palatal crib.
