Need exam please: Get examined please. Canker sores are common aphthous ulcers of mouth that occur situationally, often in response to stressors, are bacterial or viral, ; can be treated topically with many otc products that reduce local discomfort ; potentially speed healing. However, oral/dental problems a number of systemic dise;ases cause canker sore-like lesions--crohn's, behcet's, std (sexually transmitted).

White is Good: When a canker sore or "aphthous ulcer" is in the process of healing it turns a whitish color. You are on the mend. Leave it alone, don't pop it! maybe some salt water or baking soda gargles...If you want to feel better but actually, nothing is shown to significantly speed up healing once it gets to this stage. You're in the home stretch....1-2 weeks more and you'll be able to suck lemons again.
