hello friend, there are two possibilities - first is the all problems/symptoms due to dentition i.e. process of getting teeth. second - this is something going parallal process with dentition but not related to it. the most common process we studied in many cases of dentition is - during dentition, child got some abnormal sensation or pain at the site of teeth. To relieve that sensation or pain, child try to hold some object like toys, pen, finger, piece of clothes in between teeth. pressure may relieve pain, so child does it repeatedly. there are many bacteria, germs, viruses present of the object which goes inside the body of child. this will create infection in gastro intestinal system which gives symptoms related to appetite, motion, abdomen etc. it will better if you consult to homoeopathic consultant to clear this confusion. because clinical examination is most confirmatory in case of you child. if that consultant rule out second possibility and diagnosed it as dentition aggravation/ailments from dentition then there are many good homoeopathic medicines which are helpful in such a situation. medicines will selected on the basis of sign and symptoms and its evolutionary pattern. few suggestions - calc carb, opium, arsenic etc. thanking you......
