My tongue was sore on the left side, I thought it was because I bit it in my sleep, a day to two later I developed a1.5cm canker sore there overnight, within a day I had a couple more smaller canker sores on the top and sides of my tongue and one on my inner lip. The same day I noticed that I had what appeared to be small areas of inflammation on my gum line where the gums were red with brownish edges in some places. When the first sore appeared I saw my dentist who referred me to an oral surgeon who recommended coming back in a few weeks if it didn t heal. Now I m out to the country and although the first one is less painful, the fact that so much of my gums are now effected concerns me. No fever or other symptoms, I am just getting over a long bout of bronchitis . The ulcers all look like photos of canker sores, not herpes or squamous cell carcinoma . Any ideas?

Hello, Acute gum infection can also lead to swelling and soreness of gums and canker sores. There is no definite cause of canker sores, but it is known that bacterial infections, vitamin deficiency, allergies etc. can lead to canker sores.  Without clinical examination, it is difficult to give definite diagnosis. If there is throat infection present, then you can visit your physician for treatment. If there is acute gum infection present which has lead to these symptoms, then dental cleaning and or periodontal surgery will be required to correct it. In case of gum infection, maintain good oral hygiene by brushing and flossing regularly and also use a mouth wash. You can also do warm saline rinses 3-4 times a day to reduce the gum swelling. Canker sores are self limiting and will heal on its own in 7-10 days. If canker sores are causing pain, then you can apply travel over it. Take OTC multivitamins and take plenty of fluids and rest.
