<s>[INST] Hi Dr. A Chakraboty, I have a 13 year old daughter with braces and for the last few days she has had 3 white bumps on her lower labial frenulum. The area around it is sore and red . So are her lower gums in that area. She s tried putting Witch Hazel on it with q-tip,and cotton balls.We ve also tried salty warm water. What do you recommend. Please help. [/INST] Hi, Thank you for the query. White bumps about what your talking are ulcers formed because of the braces impingement or lack of proper diet leading to vitamin deficiency or stress related. This can be cured by taking multivitamin tablets for 10 days and warm salt water rinses and application of topical anesthetic will help in taking food without any pain. The area should be kept clean not allowing any food lodgment or plaque deposition which may irritate the gums leading to infection of ulceration. Hope this information will help you. </s>
