Kank-A Mouth Pain Liquid Review

Canker sores are open sores inside your mouth which expose the underlayer of skin. As with any open sore, it hurts when touched. Because it is in your mouth, something is always touching it, like saliva, so the canker sore hurts most of the time with a burning and itching sensation. The sore itself looks like a little crater, grayish-white in the middle and rimmed with bright red inflammation. As the sore begins to heal, or as you treat it with an anesthetic, the pain lessens.

The manufacturer claims that Kank-A Mouth Pain Liquid can treat canker sores as well as other sores inside the mouth that might be caused by dentures, orthodontic braces for example. Kank-A provides a protective coating and temporary pain relief and is meant for short term usage while symptoms persist. Below is our review of Kank-A


The only active ingredient is benzocaine (20%). This substance is used to lessen pain caused by teething, cold sores, canker sores, and toothaches. It is topically applied to an affected area.

The other ingredients include: benzyl alcohol, cetylpyridinium chloride, compound benzoin tincture, dimethyl isosorbide, ethylcellulose, flavor, octylacrylamide/acrylates/butylaminoethyl methacrylate copolymer, oleth-10, PEG-6, propylene glycol, ricinus communis 9 castor) seed oil, SD alcohol 38 (29.6%), sodium saccharin, sucralose, and tannic acid.


The manufacturer of this treatment suggests that the area be dried and the undiluted medication then applied with the applicator. Wait a few seconds for the coating to form. The product may be applied up to 4 times per day, or as instructed by your doctor. Applying the medication directly to the affected area is the quickest and most effective way to treat a canker sore. A built-in applicator aids in precise placement of the medication and helps prevent infections by keeping unsanitary fingers out of the mouth. The following warnings appear on the label:

Do not use for more than 7 days, unless your health-care provider states otherwise. If you experience pain, irritation, swelling, a rash, redness, or if a fever develops after using the product, stop using immediately and consult with your doctor. This product is not for any child below the age of two, and those below 12 should only use it when under adult supervision. The product carries an allergy risk for anyone who might react to local caine anesthetics such as procaine, butacaine or benzocaine. Lastly, this product could cause methemoglobinemia. This rare condition limits the amount of oxygen carried in the blood. You should consult your doctor if your skin turns gray, blue, or pale, if you develop headaches, if your heart rate increases, or you experience shortness of breath, lightheadedness, or a lack of energy.

Conclusion – Kanka-A Mouth Pain Liquid

As some positive reviews suggest, some people may experience positive results with Kank-A Professional Strength Mouth Pain Liquid. We felt the price of $8.99 for a very small bottle seemed high but it is possible that since only a small amount of liquid is used per treatment that the small bottle might last a long time. Among the negatives, we believe that because there is no form of product guarantee offered, many people will lack the confidence to purchase this product compared with competing products that do have a return policy and guarantee. There are only a small number of online reviews and they range from the very poor to the positive. Therefore at this time, we are unable to offer a positive recommendation.
