Parents can prevent early childhood tooth decay at home by implementing age-appropriate oral hygiene routines and monitoring dietary habits. The strategies vary as a child grows:

• Infants (0–12 months): Gently wipe your baby’s gums with a clean, damp cloth after each feeding to removes bacteria and sugars. Once the first tooth appears, start brushing twice daily with a soft-bristled infant toothbrush and a smear of fluoride-free training toothpaste.
• Toddlers (1–3 years): Brush twice daily using a pea-sized amount of fluoride toothpaste. Because toddlers often swallow toothpaste, direct adult supervision is essential.
• Preschoolers (3–5 years): Continue supervised brushing and introduce daily flossing with child-friendly floss picks once teeth begin to touch.
• Dietary Choices: Limit sugary snacks and drinks, such as juice and soda. Water is the best choice between meals and is the only liquid that should be in a bottle at bedtime; avoiding bedtime bottles with milk or juice prevents prolonged sugar exposure that leads to decay.
• Professional Support: While care happens at home, the Canadian Dental Association recommends establishing a "dental home" by age one. Regular professional checkups every six months allow for preventive treatments like fluoride varnish and dental sealants to supplement home care.
