Sing a long to Growing Smiles tooth brushing song to the tune of Happy Birthday and brush every surface of all your teeth with oral health coach LeighGS. During the Covid19 pandemic we have been reminded to wash our hands for 20 seconds by singing 2 verses of happy birthday. We’ve written some new words creating 3 verses to brush the outside, the inside and the biting surfaces of all your teeth. Use a pea sized blob of toothpaste (best one with at least 1350 ppm fluoride) on a dry toothbrush. Under 3? Use a smear of toothpaste. Find out more about toothpaste at with our Toothpaste Guide – Taken from our Tooth School live on Facebook recordings.
