Should a 3-month-old baby brush their teeth?

Babies who are only 3 months old usually do not need to brush their teeth, but oral hygiene should still be maintained to prevent bacterial growth in the mouth. Generally, brushing teeth can begin after the baby's deciduous teeth erupt. At 3 months, the baby's deciduous teeth have not yet erupted, so brushing is not necessary, but oral hygiene is still important. Parents can choose to use a gauze soaked in purified water or light salt water to wipe the baby's gums, taking care not to apply too much pressure. This simple method can clean dirt from the surface of the gums, maintain a clean oral environment, prevent oral fungal and viral infections, and alleviate discomfort caused by erupting teeth. When babies reach 4-6 months old and their deciduous teeth begin to erupt, brushing teeth with rinsing becomes a convenient and practical way to maintain oral hygiene. After children reach 3 years old, parents can encourage them to develop good brushing habits and cultivate their independence in brushing teeth. While brushing teeth is not mandatory at every stage of a child's development, oral hygiene and good oral hygiene habits are essential at all stages.
