<s>[INST] My 10 month old woke up one morning with red, swollen gums , foul-smelling breath, and whenever I try to brush her teeth , she cries and her gums start to bleed a little. Previously she had pearly white teeth which I brushed regularly. She is very cranky, no longer sleeps well at night, and isn t eating as much as normal. I took her to the E.R and was told she has gingivitis . I am seeking a second opinion. -Jasmine [/INST] hello and welcome, Gingivitis is the inflammation of the gums leading to redness , pain , bleeding , swelling of gums . Infection of the gums leads to fowl mouth odour which is mainly caused due to deposition of bacterial plaque, calculus or other irritants like food debris. your Baby is really very young and in her case , gingivitis is mainly because of stress due to improper sleep, poor oral hygiene and malnutrition. i would suggest you to maintain her oral hygiene nicely by regular brushing and mouth rinsing with lukewarm saline water. visit a dentist for clinical evaluation , a course of doxycycline for 3 to 5 days helps subside the symptoms but do consult a doctor before any medication. i hope this helps, take care. </s>
