How's it work?** A: I have been using this product for years in my tongue, gum, etc. It's the only thing that works. It takes the pain away within minutes. It's not a cure, since the sores are due to a virus, but it def makes the healing process less painful. I needed to buy it online bc I couldn't find it on stores and I was frustrated my husband would buy me other things that didn't work. Try it. I'm sure you will like it. Just a FYI, the flavor and feeling are funny but it's worth it. **Q: Will this work on lip or cheek bites? I sometimes bite my lip which causes swelling and pain (and frequently another bite).** A: Yes, not sure about lips but definitely if you accidentally bit the inside of your cheek, apply it and that soothing sensation will help you for a little while **Q: Can i put it on after whitening strips because it hurts after does it numb it good ?** A: It numbs very well **Q: Where it is made?** A: It does not say directly on the bottle or packaging HOWEVER it is a BLISTEX product and all their research and development along with their corporate headquarters and manufacturing is ALL located in OAK BROOK ILLINOIS. They maintain absolute control over all aspects of their products to maintain its integrity. So I would take an educated QUESS only and say KANK-A is also made in Illinois. Verify on the internet to be 100% sure. Good luck! ## Customer Reviews ### ⭐⭐⭐⭐⭐ Kank's toothache brush medication *by on Reviewed in the United States July 20, 2026* Amazing product to use for a toothache. It works instantly. Absolutely a must in your first aid kit. Easy to use it tastes and smells like mint. There were no side effects for me. Highly recommended ### ⭐⭐⭐⭐⭐ LIFE SAVER that allowed me to finally sleep and function! canker sores caused by vaping..... *by on Reviewed in the United States August 15, 2021* I suddenly developed INTENSE oral pain with 2 teeth becoming extremely sensitive. Enough pain that I literally cried. The pain must have hit a nerve because it was the bottom jaw, top jaw, to the ear and eye...The whole right side of my face. Here is what actually happened:I switched vapes and was experiencing all of this sudden oral pain. I stopped that particular vape and went back to the original. Pain almost completely stopped. I looked at the roof of my my mouth near my gum line as it felt very sensitive and somewhat raw in that area to see that I have about 4 or 5 canker sores. I never had this before, ever. You can see them MUCH easier if you shine a green light on them. I used a type of peroxide gel on them marketed for canker sores, but it dripped down onto my teeth and caused other intense pains..... IF you have sensitive teeth, DO NOT use Gly-Oxide mouth sore rinse!!! Homeopathic borax works for canker sores too.I finally discovered how to fix this issue.....FIRST thing in the morning while I had no pain was to put this Kanka on the roof of my mouth near the gum line and wait a min. THEN brush me teeth carefully with a calcium toothpaste sprinkled with some l-arginine to eliminate the sensitivity caused by the Gly-Oxide.... Repeat the same thing at night. If you have some l-arginine capsules, you can open one and put some on your toothbrush with some mild flavored calcium toothpaste WITHOUT SLS. (I used Coral toothpaste and also Biomed calcimax)This Kanka stuff is weird. I spilled it by mistake and it got all over my hand. It reminds me of super glue. It dries to a sticky coating that is hard to remove. It does numb great, but if you feel the numbing wearing off, it still works and in my case it lasted about 5 hours until I needed to do this again before bed. Once I was asleep, I did not awake because of any pain. As long as I did not hit this area with my toothbrush or a harsh paste, or chew too much on that side, I was ok.If you vape and have sudden oral pain, look to your vape first! That is what caused all of this nonsense with me so you may have recently changed flavors or brands. If that is the case, stop immediately! I almost got a root canal for no reason!This item is a household necessity. You never know when you will need it, so it is good to get one now while you are reading this. It is cheap and works! You know the next time you have a toothache will be on a Friday afternoon just as the dentist is closing...... That will be one LONG weekend for you! ### ⭐⭐⭐⭐⭐ Quick relief! *by on Reviewed in the United States July 17, 2026* Works super well and fast!! I recently fell on my e bike face first going 28 mph and the inside of my lip was cut and blistered . Couldn’t handle the pain anymore after 3 days. Decided to buy this and as soon as I put it on yes it burns but after that it gets numb and completely reliefs the area !
