My son's upper front 4 teeth started decaying when he was one and a half year old. He has been on ebf till 1.5 yr and after that became anaemic so dr suggested iron supplements. After taking iron supplements the teeth became visibly black then the color became brownish but the teeth were decaying.the right and left bicuspid also have cavity.Now he started complaining of pain in his right bicuspid so we went to a dentist. He told that the there is abscess recommended root canal for this tooth and filling and cap for all the other ones. Also said that the front teeth cap will have to be removed once he turns 6 so that permanent teeth would come easily. My son had his first sitting of root canal in which they gave injection in gums. Is there any other way to treat than root canal or if not is there any less painful way then giving injection?
I need a 2nd opinion from experts here if the treatment suggested by the dentist is correct
