question: My 9 year child has developed puss in lower molar teeth...also his upper teeth is also infected. We have consulted 2 doctors one is saying that antibiotics can cure this...but the other is recommending root canal treatment as he is suggesting that since the puss is aggravating it will infect more teeth. Also the shape of the teeth is also effected...its blackening with cavities. Please advice which solution we should go for?
