Where are all the dentists hiding?
Let me try to weigh in here...
Ivanicapeca... unfortunately, you're off base thinking stomach acidity causes this. In theory? Sure. But claiming it's due to pH changes is pure guesswork since we don't actually know the mechanism behind how they form. Gastritis might be part of the underlying issue, but it’s definitely not a rule. A shift in pH or certain bacterial colonies might trigger Candida, but it doesn't cause these kinds of erosions. Besides, oral pH shifts don't trigger immune responses—they just cause inflammation. So, basically, gastritis leads to stomatitis, simplex, or catarrhalis, and in chronic cases, enamel abrasion.
Canker sores are split into two types: minor and major.
Minor ones—small aphthous ulcers—last about 2 to 3 weeks. They're smaller and show up in multiple spots around the mouth, like on the cheeks or tongue, but never on the palate. They recur, too. They stay within the mucosal layer, so they aren't raised; they're just small, shallow, white erosions. Someone mentioned throat issues, swelling, or yellow coloring... those aren't canker sores! These heal completely without leaving a scar. Interestingly, there can be prodromal symptoms—you might feel a burning sensation 24 to 48 hours before they actually appear. They pop up a few times a year.
Then there are Major ones... big canker sores. These last 4 to 6 weeks, are over 1cm in diameter, and always leave a scar. They actually recur more frequently than the minor ones. Someone mentioned a sore lasting 42 days... well, now you see that isn't anything unusual; that's just a major aphthous ulcer. They're characterized by larger size, longer duration, and significantly more pain. You'll find them on the palatal arches, the tongue, the inner cheeks, and the lips.
The cause? Genetics. If both parents deal with canker sores, there's a 90% chance the kids will too. The exact trigger is still a mystery, but we know it's an immunopathological process. Deficiencies in Vitamin B12 and folic acid have been found, and there's likely a correlation with digestive tract issues, immune deficiencies, menstruation, stress, and even food allergies.
Treatment involves Vitamin B12, iron, and folic acid. If the discomfort is severe, topical corticosteroids might be used—in extreme cases, systemic ones, though that's rare.
