ADA accepted and suitable for various oral sores, Kank-A is the go-to solution for professionals who demand quick, reliable pain relief to keep their day moving. ## Description Kank-A combines the maximum allowable level of anesthetic for fast, temporary pain relief, with a film-forming agent for long-lasting protection. Unlike most products which quickly wash away, Kank-A’s coating holds the anesthetic in contact with the sore and acts as a barrier against further irritation. Use this mouth sores treatment for temporary relief of pain due to canker sores, minor irritation of the mouth and gums cause by dentures or orthodontic appliances, or minor injury of the mouth or gums. To assure formation of a long-lasting film coating, dry affected area and apply medication undiluted with applicator. Allow a few seconds for coating to form. Use up to four times daily, or as directed by a dentist or doctor. Children under 12 years of age should be supervised in the use of this product. Children under 2 years of age should not use this medication. Do not use this product for more than seven days unless directed by a dentist or doctor. Review: LIFE SAVER that allowed me to finally sleep and function! canker sores caused by vaping..... - 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! Review: This product works!! - I thought the brush on Kanka worked well, but the Kanka liquid is phenomenal on mouth pain! (And I've tried them all!) And it tastes good. I have a dental appliance that kinda rubs on my tongue and it's painful when eating. This liquid helps soothe the area completely and for quite a while. If you have dental pain try it, you'll be glad you did. ## Features - TRIPLE MAX - MAXIMUM PAIN RELIEF: Contains benzocaine for fast pain relief of canker sores and other sores inside the mouth - PROTECTIVE BARRIER: Forms a long-lasting film barrier to protect sores from further irritation - EASY APPLICATION: Integrated control-tip applicator allows for accurate, mess-free application - ADA ACCEPTED: Accepted by the American Dental Association - COMPLETE SOLUTION: For canker sores, denture abrasions, and other mouth sores ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0046VJ7TE | | Active Ingredients | Benzocaine | | Additional Features | Includes Applicator, Forms Protective Coating, Maximum Strength, Film-forming Agent | | Age Range Description | Adult | | Best Sellers Rank | #52,316 in Health & Household ( See Top 100 in Health & Household ) #31 in Oral Pain Relief Medications | | Brand | Kank-A | | Brand Name | Kank-A | | Container Type | Bottle | | Customer Reviews | 4.6 out of 5 stars 6,198 Reviews | | Dosage Form | Liquid | | Global Trade Identification Number | 00041388203911 | | Item Dimensions | 5 x 0.75 x 3 inches | | Item Form | Liquid | | Item Weight | 0.02 Kilograms | | Item dimensions L x W x H | 5 x 0.75 x 3 inches | | Manufacturer | Blistex | | Manufacturer Part Number | B001G7RA2M | | Model Number | B001G7RA2M | | Net Content Weight | 0.33 Ounces | | Number of Items | 1 | | Package Type Name | Bottle | | Product Benefits | Maximum Pain Relief, Protective Coating, Fast Relief, Long-lasting Protection | | Special Ingredients | film-forming agent | | Specific Uses For Product | Pain Relief | | Target Audience | Unisex-Adults | | UPC | 041388203911 | ## Product Details - **Brand:** Kank-A - **Item Weight:** 0.02 Kilograms - **Item dimensions L x W x H:** 5 x 0.75 x 3 inches - **Product Benefits:** Maximum Pain Relief, Protective Coating, Fast Relief, Long-lasting Protection - **Specific Uses For Product:** Pain Relief ## Images ![Kank-A Mouth Pain Liquid, Maximum Strength, Canker Sore Medicine, 0.33 oz | Forms a protective coating for mouth sores, maximum pain relief, includes applicator - Image 1](https://m.media-amazon.com/images/I/71M1Yc-QsiL.jpg) ## Questions & Answers **Q: There're only a couple mentions of using it on the tongue and I have repeated horrible bouts of canker sores on my tongue. 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 ### ⭐⭐⭐⭐⭐ LIFE SAVER that allowed me to finally sleep and function! canker sores caused by vaping..... *by E***E on August 15, 2021* I suddenly developed INTENSE oral pain with 2 teeth becoming extremely sensitive.

The maximum strength formula works fast, and the protective coating it forms over the sore makes a huge difference—it shields the area from irritation while the pain relief kicks in, which allows me to eat, drink, and talk without that constant, nagging discomfort. The included applicator makes it easy to target exactly where you need it without making a mess, and a little goes a long way so the small bottle lasts surprisingly well. I've tried other canker sore products over the years and nothing else has come close to the consistent relief this one delivers every single time. If you suffer from canker sores and haven't tried Kank-A yet, stop settling for products that barely take the edge off—this is the real deal and I won't be without it. ## Frequently Bought Together - Kank-A Mouth Pain Liquid, Maximum Strength, 0.33 Fl Oz, Canker Sore Medicine, Includes Applicator, Forms Protective Coating for Mouth Sores, Maximum Pain Relief, 1 Pack - Orajel 3X for Mouth Sores: Maximum Strength Gel Tube 0.42oz- From #1 Oral Pain Relief Brand - Zilactin-B Fast Acting Canker Sore Treatment - Long Lasting Protection and Oral Pain Relief of Canker Sores, Mouth Sores and Gum Irritations, Made in USA, 0.25oz Gel, Pack of 1 --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/4304287-kank-a-mouth-pain-liquid-maximum-strength-canker-sore-medicine](https://www.desertcart.us/products/4304287-kank-a-mouth-pain-liquid-maximum-strength-canker-sore-medicine) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-08-11*
