Hi, my son is 22 months old and last week developed a spot with yellow pus on the gum above his upper right front tooth. He does not seem to be bothered by it. However, we went for a regular check-up with our dentist today and he says it is an abscess . He referred us to a specialist but says very likely the tooth will have to be extracted. Is there really no other solution? This sounds a bit drastic to me.
