Dental protection should start at an early age, i.e., infants and young children should be aware of and take action to protect their teeth. 1. After birth, babies start to erupt their milk teeth one after another around 6 months, and before that, they should be aware of the protective measures to be taken. Before the eruption of milk teeth, it is best for parents to feed the baby some water after meals, or use sterilized gauze to assist in cleaning the baby’s dental bed to facilitate oral hygiene. Excessive bacterial collection is not conducive to the growth of subsequent milk teeth, so as not to lead to the occurrence of caries in milk teeth. 2. After the milk teeth erupt one after another, parents can help the baby or teach the baby to use the finger brush to clean the teeth after meals, the toothpaste is best to choose fluoride toothpaste, but to prevent the baby from accidentally swallowing. The protection of milk teeth is extremely important. If significant inflammation or decay occurs, it will affect the formation of subsequent permanent teeth. Please also seek prompt medical attention for any dental abnormalities or discomfort.
