hello,  I have an 18 year old son who has ongoing issues with mouth sores.  He began at around age 11 when he woke with swollen lips, it looked as if he had a beak.  He was dizzy, hot and just not feeling well.  The Dentist prescribed a mouth rinse and to avoid acidic foods.  It happened only a couple more times, but he has ongoing mouth/cancer sores inside.  Is this a serious condition?  He is asthmatic as well.
Hello, Read your query, as your son has mouth sores frequently don't worry this can be due to vitamin B, C deficiency, not having proper oral hygiene, stress related, hormonal influences, due to not having proper sleep, lack of nutritious healthy diet.  For this you should consult dentist and go for proper oral examination of oral cavity, go for oral prophylaxis, In meantime on cancer sore you can apply ointment Gum paint or McCoppin or Colonel for temporary relief, Do Luke warm saline gargle two - three times a day, you can take vitamin B and C supplements by consulting your local doctor, take proper sleep, don't take stress, take proper nutritious healthy diet, avoid junk food. Hope this will help you.
