Eruption blister or abscess in 5 year old?

sounds to me like it is just the adult tooth is comming through remember when the child was first getting teeth the gum would swell and turn white before the tooth popped through... same thing here but be sure to keep a check on their temp bc i will go up with an infection but a low temp might be the inflamation from the tooth comming in as well like when the child was a baby if it doesnt get better call the dentist again but i think its fine also try otc pain meds for the child and orajel to help
