I have swollen gums (bleeding), sore throat, canker sore under my tongue, in gums (group of multiple sores), in my cheeks and also in my lips.

Get Examined: Multiple oral sores make me concern about Oral Herpes Simplex Infection. You may have Strep throat ( because of Sore Throat) also. some times Aphthous Ulcer ( usually around Menstrual period) can cause ulcer on gums and on cheeks , Vitamine deficiency can cause red sore tongue and Cracks along the angle of mouth.

Evaluation needed: It is impossible to tell you what is causing your symptoms. You could have a virus but there are many other causes. See a dentist to find out what is going on.

2 separate problems: 1. Bleeding gums can be a sign that you already have, gum disease and need to see a dentist. 2. Canker sore, nothing cures canker sores or prevents recurrence. However, many over the counter antiseptic and pain-relief medications can ameliorate pain, prevent infection and promote healing.
