The purpose of the palatal bar is to enable us to have better control of your upper molars. The bar consists of two bands (metal rings) that are cemented on the upper molars, one on each side, and a small wire with a loop near the roof of the mouth, which connects to the band. Two elastics or small wires are used to secure the bar in place. For Nance appliance, there is a piece of acrylic resting on the palate. You may experience pressure during the first few days; the pressure will gradually subside. Tylenol may be necessary the first day or night to help relieve any tenderness. In addition, brushing with toothpaste for sensitivity will also decrease orthodontic tenderness. Sometimes, the tongue will acquire an imprint of the bar which may at first get sore. Rinsing with mouthwash, like mint Listerine, or a teaspoon of salt in a glass of warm water, once or twice a day, especially before bedtime will help to make the tenderness go away. Orthodontic wax may also be used to fill in where the bar and bands meet to temporarily prevent rubbing until the tissues become accustomed to the bar. Take your time when eating your meal and chew smaller pieces of food until you get used to the bar. You may also want to eat softer foods initially while your teeth are tender. It is very important to keep your appliance clean. Food and tartar can build up on the edges, so we recommend a quick rinse or scrub after meals and brush the appliance thoroughly with your toothbrush and toothpaste at least once a day. Your orthodontic appliance will usually alter speech when you first get it. Please practice your pronunciation by reading out loud. This speeds up the speech adaptation process. If the bar ever seems to be loose, an elastic or metal tie falls off, or sores do not get better within one week, please call us, so that we can schedule an appointment to check the appliance and see how we can make it more comfortable for you. The length of time the bar stays in your mouth depends on your bite. Therefore, the time may vary with each person, and can range from 6 months to 2 years.
