1. Prevention of dental caries: Babies' teeth are easily attacked by bacteria, which will lead to dental caries if they are not cleaned in time. Dental caries can not only cause pain, but also affect the baby's diet and sleep.
2. Promote normal growth and development: Poor oral hygiene will affect the appetite and nutrient absorption of infants, thus affecting their growth and development.
3. Prevention of infection: Poor oral hygiene will lead to the growth of oral bacteria and increase the risk of infection. Infants' immune system is not fully developed, so they are more susceptible to infection.
4. Establish good oral hygiene habits: Cultivating good oral hygiene habits of infants can help them maintain a healthy oral state for life.
Therefore, parents should pay attention to the oral hygiene of infants, help them brush their teeth and clean their mouths regularly, and take them to the dentist for examination and treatment on a regular basis.
