Painful
I thought this was a good product at first but it feels like I’m getting a shot into my canker sore everytime I put it on, sooo painful. It numbs a little but eventually but dries like super glue.

You're in pain? Just buy it!
I was in soo much pain because the wire in my braces perforated my gum BADLY and caused a HUGE canker sore that hurt my soul, this relieved pain ASAP!!! (i would apply 2-3 times per day bc i would eat of course). I recommend to dry the area for at least 3-5 min before applying though so it can stick then wait 3-4 min so it can dry ( i would hold my lip) it works. <3 happy healing!!!!!

Definitely relieves the pain!
[This review was collected as part of a promotion.] I do get canker sores ever so often and used it the other day and it helped so much! The smell is a tad overwhelming with mint, but not bad considering it works on painful sores. I love the applicator too because it lays right on it. Its consistency is pretty liquified, so be careful when you open it.

Surprised it worked!
[This review was collected as part of a promotion.] This actually works well and doesn’t taste bad at all. I bit my check then it swelled leading to be biting it again. I was in a lot of pain and decided to try something topical instead of just pain med pills. I was pleasantly surprised by how well this helped with the pain. I was able to go to sleep, used again the next day and found the relief to last about 3 hours. Applicator was easy to use to apply to the right area and the consistency was thick enough to not make a mess

Save me in time!
[This review was collected as part of a promotion.] Literally used this past few days as I went out of town and came back to a cold. This kanka was such a relief from annoying pain. It didn’t leave any residue at all although I would sai it’s quite strong and not irritating. The small packaging allowed me to just throw it in my bag. I used for 4 days straight and I was gone!!!! I’ll probably have this for years bcz it’s sustainable and durable. I recommend for the kanka-girlies!

Protective liquid for canker soars
[This review was collected as part of a promotion.] This is an oral anesthetic that helps to ease the pain of canker soars, denture abrasions, and braces irritation. It forms a protective barrier around the canker soar so that fluids don’t irritate it. I love that it has a convenient control applicator which helps to apply the liquid where you need it. The liquid is a brownish color and has a menthol peppermint flavor and the taste did linger for a while. When I drank something hot or cold, I didn’t experience any pain.

Quick and effective
[This review was collected as part of a promotion.] The packaging is very simple yet effective. I used the kank-a mouth pain liquid when I had some discomfort on the top of my molar. The liquid went on smoothly and helped the pain almost instantly and lasted a while. The instructions were very easy to follow. I will definitely be using it for future pains.

Works for pain
[This review was collected as part of a promotion.] This is good for teeth pain and mouth sores. It has 20% benzocaine so works good for strong dental pain. It also works for gums. This tube is small and has applicator which helps in applying without creating mess. There is no discomfort is application.

Thanks
[This review was collected as part of a promotion.] So, I didn’t use this yet, but at the end of this month I’m going to make brackets and I’m glad I’ve got this liquid. When I test it, I will add my real opinion about this product.

Works Great!
[This review was collected as part of a promotion.] This worked really well for the sores in my mouth from braces and canker sores. It provides fast relief and actually lasts instead of wearing off right away. I like that it forms a protective coating, which helps keep the sore from getting more irritated when eating or talking. The applicator makes it easy to apply exactly where you need it, and it has a mild minty taste that isn’t overpowering. Definitely a must-have if you have braces or deal with mouth ulcers.

I’d buy it
[This review was collected as part of a promotion.] I used this product on a spot that I bit myself. It numbed the pain almost immediately, and did not have a foul flavor. The relief lasted for about an hour.

Magic for your mouth
[This review was collected as part of a promotion.] I can’t tell you how many times this has been a lifesaver for me. Any time I have a toothache this is the first thing I grab. It immediately numbs the gums and tooth that had been throbbing seconds before. You have to be careful not to get it on you tongue or that will go numb as well though. It does have an applicator brush but I find it’s easier to use a Qtip to get it all over the tooth. You can also use it for any other mouth sore you may have. It definitely gets me through the long 12+ hours of a night shift that I know I can rely on.

mouth numbing
[This review was collected as part of a promotion.] This liquid helps relieve mouth ulcers or even a sore throat, as it literally numbs the affected area. Just one drop is enough for a couple of hours, and if the discomfort persists, you can continue using it. The consistency is like honey, and it has a menthol flavor. You can store it anywhere, but try to avoid putting it on clothes or furniture, as it's a bit sticky and can stain them.

Fast-acting relief for mouth pain
[This review was collected as part of a promotion.] Kanka is one of best over-the-counter products for immediate mouty pain relief. Upon application, there’s a slight sting that doesn’t last long. Then, the liquid provides fast-acting numbness. I would highly recommend Kanka to others.

Works but application is a bit rough.
[This review was collected as part of a promotion.] The kanka mouth pain liquid works okay... its a bit thicker and tastes weird. I expected it to absorb quicker than it did so a warning is that it will travel if used inside the mouth for tooth pain. The applicator is hard and i probably would prefer something soft. It requires you to dry the area to form a "coating" and that is quite hard to do inside your mouth... especially on back teeth. It does work i just wasnt a fan of the application.

Good and helpful product
[This review was collected as part of a promotion.] I thought this worked great. Me and my daughter both need a product like this from time to time and this one worked great. Easy to use. Doesnt taste bad. Lasts a decent amount of time before needing more. A little goes a long way.

Helpful product
[This review was collected as part of a promotion.] We Always keep this handy for when someone has a sore. This is easy to use and easy to store in several places so one is always handy. Kank-a makes the sore way more bearable and seems to lessen the amount of time spend dealing with them.
