Do Canker Sores Bleed
Canker sores: Canker sores (aphthous ulcers) are flat, grey painful ulcers that usually do not bleed. Cold sores, which are caused by an infection of the herpes simplex virus, first appear as crusty blisters, and may bleed if "popped". Check with your dentist to be sure exactly what the lesion is.See 1 more doctor answer
Put alum on my canker sores. The pain decreased, but the sores look bigger and whiter and bleed a bit. What's wrong with it?
Canker sore Tx: I'm unfamiliar with that product, however most products are geared towards "burning" the nerve ends to let the viral life cycle of 10-14 days subside without further pain. I have used Debacterol in my office with great results. These products don't cure the virus. They are only geared towards alleviating pain. There is no known cure.
I put alum power on my canker sores. The pain subdued a lot but the sores got whiter and look bigger. They also bleed a little. What's wrong?
Burn...: The way you treated you canker sore is basically a chemical cattery, or burn. This makes the sore feel better, but it still takes as long or sometimes longer to heal. The good thing is that it isn't painful any more. I often tell patients that if left untreated, the canker sore takes 2-3 weeks to heal. If we treat it, it takes 14 to 21 days. :)
From description: They are either not canker sores (aphthous ulcers) or it's not pus that you see, feel or taste. See your dentist right away to find out exactly what you have and how best to treat it. If you would rather not see your dentist, then it doesn't matter how you treat it as your guess would be as good as ours, considering we can't actually see what you are describing.See 1 more doctor answer
I have canker sores that sometimes have minor, brief bleeding. Is it safe to eat raw sushi? I'm worried about parasites entering my bloodstream.
Perspective: If there are parasites in your sushi, they will enter your system whether or not you have open sores. Remember, you are swallowing your food. There is always a risk with raw sushi, as well as many other not fully cooked foods. I love sushi and only go to some high quality restaurants for it.See 1 more doctor answer
Is it safe to eat sushi (raw type) when I have large canker sores at the back of my throat. No way to avoid the food touching the sores and one did a minor bleed but for a very short time.
Canker sores?: Canker sores do not usually occur at the back of your throat and therefore I question your diagnosis. I would start by seeing your own physician for an accurate diagnosis. Then you can ask all your questions.See 2 more doctor answers
Canker sores: Generally takes 7-14 days to completely resolve. How long has it been in your case? If more and/or you are concerned see your own dentists for a definitive diagnosis. Any lesion lasting more that 2 weeks needs to be examined as there are lots of other similar types of lesions that require treatment. Some can be quite serious, while others are not. Get it examined if they persist.See 1 more doctor answer
Several: The exact cause of most canker sores is unknown. Stress or tissue injury is thought to be the cause of simple canker sores. Certain foods -- including citrus or acidic fruits and vegetables (such as lemons, oranges, pineapples, apples, figs, tomatoes, and strawberries) -- can trigger a canker sore. Sometimes a sharp tooth surface, dental appliance, braces, or ill fitting dentures can trigger them.See 1 more doctor answer
Try Zilactin B,: An over the counter medication found in pharmacies. Dry area, apply thin layer, let it dry and turn white. Your dentist can prescribe a steroid in a delivery vehicle called orabase. Rx for that! Avoid toothpaste with sodium lauryl sulfate which can help cause. Avoid acidic foods. Be careful brushing not to gouge tissue. Lasers work very well, hope your dentist has one. Eat healthy! good luck!
NOT contagious: 'cold sores' are caused by virus=herpes simplex. Canker sores are associated with dental work, extra brushing, mouth injuries, spicy or acidic foods. Toothpastes containing sodium lauryl sulfate have been implicated. Canker sores may also occur in immunosuppressed patients (or hiv). Also noted are food sensitivities: chocolate, coffee, strawberries, nuts, cheese and acidic foods, e.g. Pineapple.See 2 more doctor answers
