<s>[INST] 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? [/INST] Hello,Thanks for writing to us.Since the tooth is infected associated with abscess formation,i would would suggest you to get root canal treatment done.Pus has to be drained and curetted.Medications can relieve pain/infection temporarily.Please do visit a dentist and get further treatment done.Take care. </s>
