Great product! Relieves pain and heals!!
It works!! I don't know why but I see some bad reviews and I think people either don't know how to use them or are using them wrong. These really are a lifesaver and make it heal a lot faster. I noticed if I put it on the area of my lip and there's not an overproduction of saliva and I hold it on there for like 1 minute long enough for it to attach to the skin, it stays on for a while. If it gets wet first it won't stick. You can even dry it with a cotton ball first. These are the only things that have helped relieve pain and heal it faster at the same time. I do recommend only using half if it's not real big because you get twice as much uses out of it and that way if it doesn't stick then you can try with the other half. These do not stick to gums and I think the closest to your gums the harder it is because of the amount of saliva that sits in your mouth in that area. But like I said hold it on long enough until you know it's attached and you should be good! Also, if you are constantly messing with it in your mouth it won't last as long because you will wear down the gel on the tablet. If you can get it to work properly it's 100% worth it and don't give up. If it doesn't work the first couple of times keep trying. I noticed another review also said that there was no phone number to get a hold of the company but my package came with a card with an email and phone number for dentemp on it. So maybe they did not receive one?? I will attach the photo here! I have not tried contacting the company as I haven't had any issues. I definitely recommend this over any other product that does not work or only takes away the pain for a few minutes. The photo of the tablet in my mouth is 2 hours after applying.

Please read if you have doubts
Ive never left a review on Amazon before but to say the least about this product it’s now a staple for me. I get very bad canker sores around the winter time and without a doubt this year I contracted several canker sores that made me slur and drool every time I talked. Some people loved this product and some hated it because it made them bleed but I took the risk anyway in hopes that something will help me bare with this annoying disease in my mouth. Yes it was awkward and yes it was uncomfortable but is it worth some patience to try to get this to go away yes. I used it after I brushed my teeth before bed and I woke up in the morning with a big bump of gel attached to the sore. It took some time gentling scraping off what I could and left the residue. It actually did bleed and I was devastated that it was going to extend my recovery time. HOWEVER, that entire day I did not feel any pain although it puffed up from swelling I assume but it healed in like 2 days. I’ve never used something to miraculous in my life with these sores. Please please try it out it is 100% worth it.

I tried it out of desperation
I gave this item a try out of desperation. Those of us afflicted with canker sores, especially in odd locations inside the mouth, know the unrelenting suffering that comes with a flare up. After reading all the reviews about this item and having nothing left in the house except a salt and water rinse option, I decided to try ONE tablet, just to see if it would help. It was really difficult to affix to the sore - the tablet is bulky and the sore was not in a flat location. Just as I got the pill stuck to the sore, it kind of also stuck to my finger (yes I followed the instructions about how to apply) and pulled slightly away from the sore which caused a lot of pain. The tablet sat in the spot for about 35 minutes then it started to gel and congeal. It didn't feel so bad at that point, just kind of bulky. I sensed the slight menthol taste but it wasn't overwhelming. About two hours later it had expanded significantly and became a giant-sized slime blob. It eventually started to stick to a few nearby teeth. That wasn't the problem so much as once it started to stick elsewhere it tugged away from where it was supposed to be so there was kind of a ripping feeling away from the sore and of course more pain. It's a very difficult thing to manipulate and if you attempt to, be prepared with tissues and swabs and lots of uncontrollable drooling. Like another reviewer, I attempted to "trim" the outer parameter of the blob and gently used a toothpick on the outside area of the sore. Unfortunately, what remained of the sticky blob just kept expanding in its place. I decided to just leave it be and let it run its course as it seemed way too risky to remove it. In the end, it didn't contribute to healing the sore but it did cover it up for a few hours. I have yet to find a good OTC product that works to alleviate the pain, as well as the canker sore itself. Most, like this, are very expensive and yield mixed results at best.

Pain free but still has problems | Update: It worked
I have a huge sore behind my top lip—this thing has hung around longer than my dad. I’ve tried everything to get rid of it and ease the pain so I can eat fruit gummies but numbing only last so long and drinking is awful. The cost is outrageous for what you get, but it did apply easy. I stuck it right on and it stayed(it did burn for several seconds but that died down). Be careful not to touch it with your lips because I almost sealed my bottom lip to my top lip, this thing STICKS. I’ve had it on for roughly an hour—and it has dissolved somewhat, but not nearly close to what it claims. The box said 30 minutes and it’ll dissolve to a thin, clear film, right now it’s like a gelatinous puck. While that is slightly annoying, it has helped with the pain. I can talk without being in immense pain, I can lick my lips again HALLELUJAH! I use a straw to drink(sorry turtles), and am only eating foods I can stick in the back of my mouth (jello, fruit snacks, turkey sticks, mac and cheese, etc.) While I wish there wasn’t this mushy hockey puck stuck to my lip, I will take it over the pain. Update: so I had it on for 3 hours and it still didn’t dissolve fully. I had to peel the gunk off with my hands because it started sticking to my teeth and lips. Gross and ow. But it did leave the clear film over the sore so yay? Overnight the film also balled up into gelatinous gunk that I had to peel off. Overall I got roughly 3-4 hours without pain. Update 2: I used it again the next night, same deal. Didn’t dissolve, peeled off gunk before bed. This time I don’t think the film stayed on. It kind of slid to the side which is annoying but I was still pain free while I had it on. Just used some numbing Orajel before going to bed. I’ve noticed that these are actually healing this sore. I’ve tried the Colgate sore rinse, orajel, even my husband made ‘Magic mouthwash’(he works in a pharmacy). Nothing worked. These patches seem to actually be healing the sore relatively quickly THANK GOD! Worth it to me right now, but I would probably only spend the money if I had a bad sore that just won’t go away. If you have small sores in hard to reach areas, just rinse it. Dont use these.

This works!
This DOES work. It completely covers the sore which keeps it away from the acid in your mouth that keeps canker sores from healing. It also completely stops the pain while it’s on. If you apply it wrong it will *not* work. It’s all on you. It cuts healing time down from 10 days to 3. It turns into a huge, thick disgusting gelatinous blob, which is exactly what it’s supposed to do, so I use it at night while I’m sleeping. I break it into quarters because it expands, and expands, and expands! and covers the whole sore. What works: BAKING SODA. If I bite my lip, I immediately start putting baking soda on it 3x per day. I get a weird taste in a spot where a sore is starting so the second I notice that I use the baking soda. Baking soda oftentimes prevented the sore from developing at all. I brush my teeth with straight baking soda while that’s going on. Tylenol. I’m not generally an idiot so I’m not sure why it took me decades to figure out that pain medication works. Do not use Advil, Alieve, meloxicam, ibuprofen. All of those *cause* canker sores. I finally had to start telling Drs I was allergic to meloxicam to stop them from prescribing it. Silver nitrate is something a dentist can apply. It cauterizes the sore. It doesn’t ‘sting’ when it’s applied, it is searing agony. Other than an actual canker sore it’s the worst pain I have ever felt. Tears rolling down my face, I felt it in my whole jaw. And then it’s gone. Completely. 100%. The whole thing, the sore, the searing agony; all of it, gone. Use only SLS free toothpaste. I use hello for kids. It works plus it’s sparkly & tastes like bubblegum! Whatever you use, it must be SLS free. AVOID! Chocolate Anything with any citric acid. (Did you know there’s citric acid in jelly beans?!? Yeah, me neither. Now I do though!) check all labels to make sure. Any & all forms of Vitamin C Sushi (Sushi?!?!? Yup, don’t eat any sushi while there’s a canker sore situation going on. Back to this product: Apply it correctly and then leave it alone! Don’t poke at it, pick at it, try to move it, nothing. Leave. It. Just enjoy the globby, gelatinous, stuck all over your mouth pain relief it provides.

Does the job, but causes tooth sensitivity!
PROS: - lasts for quite a while! (the patch stayed on for about 3-6 hours, even when eating) - easy to apply - simple instructions - numbs and heals sore/wound it's covering - protects sore/wound it's covering well CONS: - causes tooth sensitivity - not enough canker covers, in my opinion I bought this because I was in SO much pain after accidentally biting my lip in the same spot. These "bandaids" came in very quickly, were easy to use, and did the trick! As stated earlier, the bandaid would cover the wound for about 3-6 hours, even when you're eating, before completely melting away. However, because it numbed my sore while applying it on (you feel a searing minty flavor, kind fo spicy, on the wound when you first apply it, but it eventually goes away after about 10-20 minutes), when it completely melts, you have maybe about 5-10 minutes before it starts getting sore again. I used 5 out of 6 canker sore covers before my wound completely healed, and honestly, it was a great help! I was able to speak, sing, and eating with little to no pain using these. However, I'm giving it three stars because it gave me some pretty bad tooth sensitivity. The tooth the canker sore cover was pressed against became extremely sensity for the next two weeks. It was irritated by cold air, foods, and chewing, making it difficult to eat. After those two weeks, teh sensitivity was still there, but more bearable. It's been about two months since then, so it's pretty much gone completely away, however, it was very annoying. Overall, I would use this product again because it did relieve a considerable amount of my pain, but probably not consistently over long-term use because of the tooth sensitivity issue.

Absolute lifesaver.
I am so thankful I found these. I had an ulcer on the side of my tongue and it was miserable. These made it so I could talk, eat, and drink without pain. So easy to apply. Causes a little discomfort for the first couple minutes but then it’s just menthol cooling relief after that. When used right it stays on for hours. I did have a couple come off after having warm liquids like soup, but I think it was because they hadn’t been on long enough yet. So just make sure it’s been on for a while and is stuck on before eating. It took only 6 tablets to almost completely heal my ulcer which was a little over 2 days. Amazing.

It really works
It works. When you have an especially painful one this stuff really helps heal it and takes away the pain so you can sleep. I didn’t like the giant gob of gelatinous goo in my mouth so I tried grinding it into a powder and applying a small amount directly on the ulcer. This worked for me and especially on ones in tough locations like inside the lip or side of tongue. I also use zinc and h. Reuteri dsm 17658 and those supplements help them heal faster too.

Worked like a charm
Tried this on a whim - it worked amazing - canker was gone after 2 days use

It works wonderfully
Actually it works when you apply it in aright way.. the tablet is big in size but once the canker observes it then it’s more comfortable to handle. It removes the pain in the same day

Works!
The most important thing is that it works! It is extremely expensive but when I have a canker sore I feel like I’d throw any amount of money at it to make it stop. So when you wake up in the morning the tablet has turned into a giant piece of sticky goop which is not appetizing, doesn’t taste great and is kind of nasty but I don’t feel the canker sore and it made it heal very fast since it wasn’t exposed to saliva. So it’s a win to me.

Ulcer gone after 1 tablet
I didn’t have much faith in this product but I have to say it’s really impressive. I’ve used one tablet yesterday it has dissolved over 6 hours approximately, a was able to eat and drink without any pain which is a great relief. And today the ulcer is pretty much gone. Next time I’ll only use half of the tablet because whole thing is way too big

Garbage
Doesn't work it's just a pill that you hope stick's. Don't waste your time or money .
