LIFE-CHANGING!
I rarely leave reviews for products, but this powder has improved my quality of life tremendously. I have tried so, so many canker sore remedy products with various degrees of success, but this blows them all away. I’m still in disbelief about how well this product works, but I have been using it for eight months now with massively positive results. For my whole life, anytime I bump my inner cheeks while eating, scratch any area while brushing my teeth, absentmindedly bite my lip even slightly, etc, I will get a canker sore. I used to live in fear of this happening, because the majority of the time they develop into horrible, red, angry canker sores that take days to weeks to heal and frequently leave scars. I get a fever and swollen lymph nodes all down my neck and back during that time, and just generally feel like trash. Awful. Every single time I feel a canker sore coming on, or even sometimes just preemptively when I bite myself, I apply this powder to the area 3x per day. Yes, it burns. Yes, it tastes strange and intense. BUT! I have not had a SINGLE bad canker sore since I began using this! I am shocked to be typing this, as I had given up on these types of products after trying so many. For me, this is nothing short of miraculous. After the first few successes with this, I cried in relief. Some tips: - Scoop some out with a clean spoon and use a clean, damp finger to apply it directly to the damaged area. Wiggle your finger around gently during this time to collect moisture and help it penetrate. Hold it there until the pain reduces. This often takes around 2 minutes for me. - After the pain reduces, tilt your head to allow it to pool only in the affected area for a minute or so, moving and stretching the area to really work it in and allow it to absorb. - Don’t swish it all around your mouth unless you really need to hit all the areas! It changes my taste sensation for around 12 hours when I do this, and makes some foods taste awful. Doing it the way I have detailed above keeps it from getting on my tongue, avoiding this problem. Sometimes when I am dealing with several possible sores, though, I do this anyways. Better some bad tastes than canker sore hell. - Apply it over a sink so you can let the saliva that it triggers run out of your mouth, keeping the powder from spreading to unwanted areas. - Rinse thoroughly and repeatedly with clean water after spitting as much as possible out. - Do it after brushing your teeth before bed. I have much better results this way, often clearing out the area in 1-2 days. I cannot recommend this product enough. Whoever formulated and made this, THANK YOU from the bottom of my heart. You have truly changed my life for the better and I will buy this product forever.

Best Canker Sore Remedy I've Tried
I don't write a lot of reviews on Amazon purchases but felt it necessary for this. I've been dealing with Canker sores since I was an adolescent (now in my 40s) and couldn't find a remedy good enough to help cope with them. When I stumbled upon Canker Shield in my search, I was already in a 5-sore outbreak and needed something quickly. This came within a day or two and has been the best option I've ever tried. I couldn't say for sure that it helped them heal faster, but it at least helped sooth the pain for the duration of most of the day, which allowed me to talk somewhat normal in work meetings. The way to apply it to where it's most effective, from what I experienced, is to do so after you brush your teeth in the morning and at night. I would dampen the tip of my finger with water and dab it into the powder so some would stick. Then I would put it on each sore so they had a layer of it applied. The IMPORTANT thing is to not have the powder rub off of the sore on any other part of your mouth at first. So you'll have to sit in pain over the sink for about 60-90 seconds to let it air out while drooling. Afterwards, I would just wipe the outside of my mouth so the powder could sit on the sores for another 3-5 minutes while I go do other things. Then I would do a quick water rinse to get the excess powder out of my mouth. If you're reading this review you're obviously someone that suffers from these as well. I think as a "Community" we should promote remedies like this as much as possible to help each other out. And if you know of something available that's even more effective than Canker Shield, then definitely let us all know!

Not Perfect, but Does Speed Up Healing
Like a lot of the other reviewers here, I get canker sores regularly. The biggest help I've found is brushing daily with a tea tree oil toothpaste (natural antiseptic.) Regular use of tea tree toothpaste took me from 3-4 sores a month, to 1-2 a month. I was still really suffering even with fewer sores. I decided to try this product specifically for the claim that it speeds up healing. When I felt the tell-tale irritation of a canker sore developing, I used this product right before bed. First, it's not easy to apply. Trying the "pinch" method that the label describes didn't work for me. It barely got on the sore directly. So I sucked on my forefinger to get it wet, then dipped it into the powder. The powder stuck to my finger and then I held it directly against the sore. I did this 3 times to get plenty on their. The package is correct that you start salivating immediately. I recommend doing this over the bathroom sink because I was drooling while I was pulling my lip open trying to reach the sore. Once I had a good amount on there, I tried to just let it sit for a minute. IT TASTES TERRIBLE. It's a weird mix of sour/citrus/bitter. I had to fight the urge to spit it out as I started to swish it around. I didn't last the full 3 minutes recommended. I went to bed and repeated the process again in the morning. Anyway, on the plus side, it did numb my mouth. On the minus side, the numbness was gone in about 45 minutes. But the big take away for me is that the sore was gone by the end of day 3. My sores usually last at least a week. I will definitely use this product again at the first sign of a new sore developing. Don't expect miracles. The sore will still hurt until it heals. But I experienced a shorter duration using this product twice a day (morning and bedtime.)

Very painful.
It's hard to tell if this product would have worked. I had repeating canker sores and was desparate for pain relief and healing. More sores were causing pain to the point that I could hardly eat, talk or swallow with out tears running down my face & my nose watering. This product looked promising. Unfortunately, it caused even more excruciating pain once I applied it. I tried to apply 3x times at different intervals hoping it would subside. It felt like I stuck my tongue in a light socket. Pain shot through my face and head. I honestly would not discourage someone from trying this product. I wonder if my cankers were so painful because of thier location on the tip of my tongue. Anyway, that is my honest review. I hope this product is more helpful for you if you try it.

Did not like the Powder concept.
I am very prone to cankers....I assume from stress, but who knows. I read the reviews on several products and this one seemed to be worth a try. It was alot more expensive then I wanted to pay, but then I thought you get what you pay for... First of all it's a powder....you are supposed to take a pinch and put it on the canker, then you will salivate and swish. Well that's fine if the canker is on the bottom lip. I did not like the flavor of this at all, it's hard to describe, maybe like a sour citrus taste. Did it work? Maybe? I had a couple of cankers and I bit my tongue, it did not help with my tongue. The canker seemed to heal, maybe a little quicker then normal OTC products, but hard to say, seeing I had them a few days prior, to getting this product and was using other OTC products in the meantime. I don't think I would recommend this...basically because it's a powder and the taste was not very pleasant to me.

Miracle Powder!
Works extremely well! I have to take an immunosuppressant that tends to cause mouth sores and not even a prescription steroid cream helps get rid of them. I use a damp qtip to dab on and that worked really well. It does sting a little but then has a little numbing factor to it after. I also noticed that my sores didn’t hurt for several hours after using it, and by the next day they hardly hurt at all and were healing. Without this powder it was taking weeks for them to heal! Someone said it could tastes really bad, it’s not great but tastes like clove so I feel like it’s tolerable.

Please try this
I have had a long history of horrible canker sores. I’ve tried all of the solutions, salt rinses, milk of magnesia, alum, oral wound mouth wash, all of the canker covers and they mostly just managed the pain. One day in another desperate attempt to find a better solution, I found this. This has improved my quality of life when I have canker sores. It is not an overnight solutions for the really big ones, but it does aid in fast healing and helps reduce the pain. For smaller sores, or ones you catch early, it almost does heal it overnight in my experience. It tastes horrible and leaves a weird layer in your mouth but I just brush my teeth after to get the taste out. Please try this if you’ve been in misery when you get canker sores. I would not rate this so highly and leave a review if I didn’t think it actually worked. I truly have felt your pain and have been in the trenches with canker sores. I believe this product is the best solution I’ve found so far!
