Teeth Whitening Products

Over-the-counter teeth whitening products (strips, trays, whitening toothpaste) are likely safe while breastfeeding, but there's limited research. The hydrogen peroxide or carbamide peroxide is applied topically to teeth and the amount swallowed is very small. Most dentists suggest waiting until after breastfeeding for elective professional whitening treatments, though this is out of an abundance of caution rather than demonstrated risk.

Always confirm with your doctor or lactation consultant before making dietary changes while breastfeeding.
