It’s actually a myth that teeth cut through gums as they emerge. When a new baby tooth pops up, special chemicals are released that cause the gums to separate and allow the tooth through. Food or bacteria can get stuck around new teeth popping up and this is what can cause inflammation and discomfort. Try to keep your little one’s gums and any teeth they have nice and clean by brushing twice a day, as a clean mouth can help to prevent teething pain.
