My 3 year old Niece got ulcers in her mouth for the past 3 days. One on her tongue, palate,inner cheek and few on her gums. it looks reddish, not large but not like spots and is painful in between. It did bleed once. She has a bad breath in between and her lips are dry and she gets a dry cough sometimes in the night. Is it bacterial or fungal infection? What treatment must be given? One doctor gave Lacobacillus gel while another gave miconazole. Kindly advice.
