I brought my 4 year old son to a dentist and he treated my son's upper molar, prescribed amoxicilin 2days then extract it.should i seek 2nd opinion?

Second opinion : If your son had no symptoms, you should seek a second opinion, only if you have doubts about the treating doctor. Usually, the reason to extract a primary tooth in that type of situation is that it had an abscess. Going for a second opinion is a reasonable thing to do.

If you'd like: It sounds like your sons tooth was decayed to the point that it could not be saved. When the dentist prescribes an antibiotic, that means the tooth was decayed and abscessed. The antibiotics will bring down the swelling and infection before extraction. It is always your right as a patient to seek a second opinion if you'd like.

If you wish: It's always important for one to have confidence and trust in the doctor providing services. If you have any hesitations and it would make you feel better to get a second opinion, then you certainly should.

Never wrong: Never wrong to seek 2nd opinion. That said, if child had badly decayed (infected) tooth & was given antibiotic to reduce spread of infection before doing extraction, sounds like the prudent thing to do. 2 suggestions: 1. If molar lost your child will need space maintainer. 2. 1st dental appt age 1, and every 6 months after that.
