Fixed Palatal Crib

Fixed palatal cribs are a type of “habit appliance.” The device is made from metal and goes inside the mouth, attaching to the upper teeth. It has semicircular wires designed to keep children from pushing their thumb or other fingers against their teeth.

Since the child cannot put their thumb where they usually do, the fixed palatal crib can often eradicate thumb sucking completely. Common issues associated with prolonged or vigorous thumb sucking include:

• Teeth misalignment.
• Crossbite.
• Anterior open bite.
• Abnormal swallowing.
• Altered speech.

If you believe your child is at risk for future teeth problems, consult a professional as soon as possible.

If you have a child older than 3 who has continued to suck their thumb or other fingers, you should take them to be fitted for a fixed palatal crib. Most thumb sucking stops, but if it doesn’t or if your elementary- or middle-school-aged child has jaw or teeth abnormalities, consider scheduling an appointment for an assessment.

How Long Does a Fixed Palatal Crib Need to Be Worn?

After your child has the initial consultation — usually involving X-rays, dental impressions or photographs — the orthodontic team will create a custom-made fixed palatal crib. Usually, the device only needs to be worn for a few months to ensure the behavior has stopped. Your child will be monitored during that time.
