After sealant treatment, it’s important to avoid chewing on ice cubes, hard candy, popcorn kernels, or any hard or sticky foods. Your sealants will be checked for wear and chipping at your regular dental check-up. Combined with good home care, a proper diet, and regular dental check-ups, sealants are very effective in helping prevent tooth decay. This means brushing and flossing regularly, and avoiding foods in high sugar.
