Many of us were taught at an early age to rinse our mouth out immediately after brushing our teeth. Researchers have discovered that this is actually not the best method. It seems that a brighter smile and fewer trips to the dentist are the direct results of allowing a portion of the paste to remain. This will help to maintain healthy gums as well as to strengthen tooth enamel, leading to fewer issues such as cavities and periodontal disease.
