Habit Appliance

Habit appliances, also known as habit breaking appliances, bluegrass appliances, tongue cribs, thumb cribs, or palatal cribs,  are specialized dental appliances that are used to break detrimental dental habits in children. Most commonly, habit appliances are used to discontinue behaviors such as finger or thumb sucking. Habit appliances still allow the child to place their finger or thumb in their mouth, however they make it more uncomfortable, which eventually discourages the child from continuing this behavior. Habit appliances work best when parents help reinforce the treatment as well. 

Did You Know?

About 95% of babies practice finger or thumb sucking during their first year of life. This number drops down to about 6-10% of toddlers using pacifiers or thumb sucking by the time they reach the age of four. While the American Dental Association notes that thumb sucking has some self-soothing benefits at a younger age, they recommend that children discontinue this behavior after the age of four. Continuing to participate in detrimental habits could cause your child to suffer from long-term effects later in life.
