Once your baby's first tooth appears, it's time to start a simple routine. Research suggests brushing twice daily with fluoride toothpaste strengthens developing teeth and sets up habits your child will follow for years. You're establishing patterns now that matter later. Skip bottle propping and frequent juice—studies indicate both increase cavity risk and can affect your baby's weight. A health visitor or pediatrician can show you the right way to clean your baby's gums before teeth come in and teeth once they do. Starting dental care early prevents painful cavities and saves money down the road. These early visits are usually quick and often covered by insurance. Think of infancy as your window to build a foundation for lifelong dental health.
