Help, what type of tooth filling is best for a 4 yr old?

Talk to dentist: Depending upon what tooth is needing a filling, a white composite filling or a silver amalgam filling will be fine. If the child is 4, it would be a deciduous (or baby tooth) most likely. The child will lose the tooth when the permanent comes in. Also, talk to the dentist about how long the tooth will be retained to help you make a decision. In our office, we only do white fillings for esthetics.

Depends: Depends. Which tooth has the cavity? If it is a front tooth, those teeth are lost around 6 or 7. A 2nd molar though, isn't shed until 12-13. Where on the tooth is the decay? How compliant with dental work is the 4 year old? Will he/she require some form of help (sedation)? Have a pediatric dentist examine this child ; you will have your answer.

There are a multitud: Of restorative materials available. The individual situation will dictate which type of restorative material would be best suited. Please consult with your dentist or pediatric dentist. Hope this helps.

Either can work fine: The tooth colored filling will require that the child be a bit more cooperative to keep the area dry. If it gets wet during the placement it can fail and have to be done over.

Not age related: Ask your dentist what's best for your child. Has nothing to do with age. Has to do with what material will work best for your child's problem. Depends on size, location, stress bearing, and many other factors. Again, ask your dentist.
