Irritation of lips and cheeks from braces rubbing tends to occur when the braces are first placed. Wax is available and will have been supplied to you in the kit given to you when the braces were placed. This wax can provide you comfort while you get used to your braces. To apply the wax, pinch off a small piece and roll it into a ball the size of a pea. After the wax is squeezed into a small disc, push it onto the brace where the irritation is occurring.
