Usually the two lower front teeth (central incisors) erupt at about six months of age, followed shortly by the two upper central incisors. During the next 18 to 24 months, the rest of the baby teeth appear, although not in orderly sequence from front to back. All of these 20 primary teeth should be present at two to three years of age. 
 



A Rapid Palatal Expander(RPE) is an early orthodontic treatment used to correct a crossbite, and are the most common orthodontic appliance used to expand the palate of young children.  Dr. Glenn typically recommends an RPE for a child with a posterior crossbite around 5-6 years old, depending on how the child will handle treatment.  Most patients feel pressure on their teeth throughout treatment, however experiences may vary.

The RPE is placed on the palate with 2 rings around each molar.  There is a key used to turn the expander twice a day for two weeks; each turn expanding the palate in small increments.   During treatment, some children start to see a gap between their front teeth; this is a positive sign.  A typical crossbite will be corrected by the RPE within 3-6 months of use.
