DES MOINES, IOWA (February 19, 2020) — The routines behind developing a healthy smile and better overall health can start with taking two minutes twice a day to brush your teeth. Delta Dental of Iowa Foundation made that healthy habit easier for 421,000 Iowans in 2019 by providing a free toothbrush. February is National Children's Dental Health Month, so it's the perfect time to remind Iowans about the importance of educating kids about good dental hygiene habits.
