In fact, these problems can be prevented. How do you choose between treating or preventing disease? The American Dental Association (ADA) reminds parents who are new parents that they should take their babies to the dentist within six months of their first class of teeth, and no later than their baby’s first birthday. The ADA’s dental consultant, Kimbley K. Harms, said, “The baby’s first visit to the dentist should be within six months of the baby’s first lesson. Dr. Harms said, “Only if parents technically take their babies to the dentist, the doctor can save how to ensure that the baby’s oral health to provide parents with appropriate advice, and now many babies due to the lack of idea of dental health as a child, the result of the teeth have become cavities.” Before the age of one, parents learn how to help and teach their children to protect their baby teeth; from 2-5 years old, they visit the dentist at least once a year to ensure that their baby’s baby teeth are treated in the early stage of tooth decay, which can prevent toothache; from 6-13 years old, during the tooth replacement period, they visit the dentist once in 3-6 months to assist in tooth replacement and do guttering to protect permanent teeth; after 13 years old, they visit the dentist once a year to ensure that permanent teeth are treated in the early stage of tooth decay, which can To prevent pain and complicated treatment (time and cost) caused by deep tooth destruction; after the age of 18, visit the dentist once a year and have a dental cleaning to prevent periodontal disease.
