I feel like I've been plagued by misinformation or people with misinformation tonight.
Let me explain.
I am a frequent sufferer of canker sores (mouth ulcers). I always use Crest toothpaste (until now) that contains Sodium Laurel Sulphate, I have a horrible diet (drink soda like a fish, eat pizza constantly), have sharp teeth and anytime I cause damage to my internal mouth flesh a canker sore will appear. It could be from biting it, or my mouth rubbing against my sharp teeth, or a toothbrush slipping off and hitting a corner of my mouth. But it's clearly a combination of bad diet and physical damage. And I generally only get one at a time. I don't get like an "outbreak" of them at random times or anything.
Any research I have done says it is NOT viral and is NOT herpes.
But I had a really really bad one the last few days, like a constant burning pain because it was big, even had a swollen lymph node. My mom called the dentist to see if he could prescribe Aphthasol and he did not but he prescribed something else; Acyclovir.
I went to pick it up at the pharmacy and it said it was an antiviral used to treat things such as chicken pox, shingles and herpes. So I asked the pharamacist and she said canker sores are viral and I'm like umm no they're ulcers and she flatout told me they're caused by herpes. I didn't feel confident in the recommendation so I got a refund.
What do you think? Were they right or wrong?
