Changing your brush at least every three months is hygienic and healthy. Studies have shown a correlation between gum disease and heart disease, diabetes and more.  And, most people use a brush that is too large for their mouth or not suited to their individual needs. Dr. GoodMouth’s personalized brush suggester helps you find the perfect brush.   Plus, for every subscription purchased, Dr. GoodMouth donates 2 brushes, or the equivalent in dental care, to someone in need.  Check out the Dr. GoodMouth video!
