Hi my name is Simone and  about a month ago the inside of my bottom lip started to get raw. There are small bumps that I cant see but I can feel them in my mouth. Everytime I brush my teeth, the flouride burns my mouth a lot. I am only 15 and Im really scared to know what is causing it. On my top lip on the inside is really sore, but I dont know why. The burning gets worse everyday. There are also cracks on the inside of my mouth and blood comes out of them. If I could have some help, that would be great. Thank you.
Thanks for your query, I have gone through your query. The possible causes for the burning sensation in the mouth could be because of lichenoiid reaction that is allergic reaction to the toothpaste, or it can be because of angular colitis secondary to anemia, or it can be an authors ulcer. Consult an oral physician and get yourself examined to rule out these things. If it is a licensed reaction then you can change the toothpaste and use topical steroid like triamcinolone acetone 0.1% 4-5times daily after food. If it is because of angular colitis improve your nutritional status, consume a lot of leafy vegetables. If it is afoul ulcers then, you can take topical anesthetic and analgesics like Anabel gel. Apply 3-4 times daily before food and topical steroid like triamcinolone acetone 0.1% 4-5times daily after food. I hope my answer will help you, take care.
