Do all of a child's teeh fall out as they grow up, or are some permanent from birth? Why would a dentist encase a child's (6 year old) lower molar in silver to treat a filling ? ...Anthony in MA
Anthony, all children end up having 20 primary/baby teeth. These teeth usually start to come in at 6-9 months up to around 3 years of age. The back primary/baby teeth stay until 10-13 years of age and the front teeth 6-8 years of age.
Once these teeth are lost, the permanent teeth come in and stay. Whenever a child has a cavity, we clean the cavity out and place a filling material. The filling material in your child's mouth is a silver/amalgam restoration.
Depending on the size of the cavity, we can either place a silver filling, a composite/tooth-colored filling, or a stainless steel crown. All of these restorations fix the tooth. I hope this has helped.
