It is possible to have some kind of blisters in the mouth after the dental procedures which may be due to some abrasions during the procedure. You have not mentioned how is your son/daughter responding. If the child is not having any symptoms like fever
, irritability, lymph
node enlargement, you can wait and watch. No need to watch this blister so closely more often and just allow it to heal on its own. Visit your dentist
again only if symptoms worsen.
