Kank-A Mouth Pain Liquid - Does It Work?-Review

What is Kank-A Mouth Pain Liquid?

The following review is for Kank-A Mouth Pain Liquid. Canker sore and other forms of abrasion in the mouth and on the gums can be very painful. The manufacturer of this product believes they have the solution to the problem. They claim to have a product that will aid as a long-lasting barrier that will protect the area that is affected. They have designed a product that contains anesthetic properties which provides temporary relief. Learn more about Kank-A Mouth Pain Liquid by reading our review below.

Ingredients & How It Works

  • Benzocaine
  • Benzyl Alcohol
  • Cetylpyridinium Chloride
  • Compound Benzoin Tincture
  • Dimethyl Isosorbide
  • Ethyl Cellulose
  • Flavor
  • Octylacrylamide
  • Acrylates
  • Butylaminoethyl
  • Methacrylate Copolymer
  • Oleth-10
  • PEG 6
  • Propylene Glycol
  • Ricinus Communis (Castor) Seed Oil
  • SD Alcohol 38B
  • Sodium Saccharin
  • Sucralose
  • Tannic Acid

The main active ingredient found in this product is the anesthetic, Benzocaine. For this to be an effective canker sore product, it should contain ingredients that have dual-action, namely to provide relief from the pain and also prevent a re-occurrence thereof. This product only provides temporary relief to the affected area.

Persons who are allergic to Benzocaine, should not use this product. Another warning is that the product may cause methemoglobinemia, which reduces the amount of oxygen carried in the bloodstream.

Daily Serving

The liquid has to form a long-lasting film coating. To assure this, first dry the affected area. Then, apply the liquid with the applicator. This product does not need to be diluted before use thereof. The liquid will need a few seconds to dry before forming the film coating. Apply it about 4 times a day. If the symptoms continue after 7-days of using the product, please consult a doctor.

The Cost

The product cannot be purchased from the manufacturer's website. One can however locate a retail store by following the instructions on the manufacturer's website. There is no price made available on their website. It can still be purchased online, although one will have to do this through Amazon. For a 0.33 fl oz bottle, one will pay $8.99.


We were quite concerned when we found no evidence of a money-back guarantee on the manufacturer's website. This is quite a problem for first time customers who wish to try the product for the first time. If they find that it does not work for them, they would prefer returning it for a full refund.

Our Review Summary Of Kank-A Mouth Pain Liquid

We have found a few things that we like about Kank-A Mouth Pain Liquid. The manufacturer provides the user with clear instructions on how to use the liquid and how frequently it should be applied.

Unfortunately, we do have a few concerns about the product. First of all, there are essential ingredients lacking from the product. These ingredients would help prevent the symptoms of canker sore to reoccur. Lack thereof makes the product an ineffective dual-action treatment. Furthermore, the manufacturer lacks the presence of a money-back guarantee. First time customers would prefer having the freedom of returning the product for a full refund if it does not deliver the results that it should. These reasons lead us to believe that the product is ineffective and we do not recommend Kank-A Mouth Pain Liquid.
