A U-shaped baby brush typically refers to a specialized toothbrush designed for infants and toddlers who are just starting to develop their teeth. These brushes are often designed to be gentle on the gums and delicate new teeth of babies. The U-shaped design allows for easier brushing, as it can fit over the caregiver s finger or the baby s finger for more control during brushing. The bristles are usually soft to avoid irritation to the baby s sensitive gums. Some U-shaped baby brushes also come with features such as silicone bristles, which are gentle and easy to clean. These brushes are an essential tool for parents to help maintain their baby s oral hygiene and promote healthy teeth and gums from an early age.
