Baby's first toothbrush and stages by age: Radius Kids Toothbrush
Radius is a children's toothbrush brand created in 1982 by two American architects, known for ergonomic designs sold in four stages: 6 months, 18 months, 3 years and 6 years. The writer received Radius toothbrushes from the brand and explains when to start a baby's first toothbrush, how each Radius stage differs and what to look for when choosing one. The verdict: rather than going by age alone, check how many molars have come in and whether the baby teeth are complete before picking a Radius stage.
