My daughter is 9yrs. she keeps getting canker sores on gum line. why is this and what can i do to ease the pain?

See a Dentist: Make it sure that she observes proper hygiene habits. Check her diet and keep the sugar intake in moderation. See to it that she drinks plenty of fluids. Sore usually heals within 7-14 days but laser treatment can accelerate thee healing. Fruits like banana can irritate an ulcer. There are over-the-counter topical ointment that can be used to relieve the discomfort.

Irritants?: The cause of canker sore (ahphous ulcers) is not known. They tend to occur when patients are stressed along with an irritation to the area. It could originate from improper\overzealous brushing. Have her use a soft toothbrush. Ome patients have reactions to certain foods that contain cinnamon, or ingredients in mouth rinses, toothpastes, etc. You can try to eliminate possible causes 1 at a time.
