Users Review Canker Cover for Canker Sores Study Shows Canker Sores Healed in 24 Hours

Eugene, Or (PRWEB) February 13, 2008

An old adage states, “If it sounds too good to be true, it probably is.” But two studies now confirm news what sounds too good to be true for canker sore sufferers — a unique oral patch treatment for canker sores gets rid of most canker sores in just 24 hours.

In the latest study, Canker Cover, was compared to a standard treatment containing benzocaine. Benzocaine is a pain relieving substance and is the main ingredient in most canker sore products. The median healing time for patients using Canker Cover was 24 hours compared to 120 hours for those using the benzocaine product.

How does it work? The Canker Cover patch, or disc, is placed on the canker sore. It adheres within seconds and forms a clear, gel-like protective ‘seal’ that lasts 8 to 12 hours. It won’t come off while eating. In the newest study (Drugs in R & D, Jan. 2008), 86.9% of the oral patch patients said they would use the treatment again, compared to 50% of the oral solution group.

“Canker Cover is the most effective OTC canker sore treatment,” said company president, Eve McClure. “Canker sore sufferers are finding that our product provides superior pain relief while getting rid of most canker sores in just one day, an average healing time that no other product has achieved.”

“When we tell people what our product does, they are a bit skeptical,” noted McClure. “But then, the letters come in, like this one from a user in Wisconsin”.

“Okay, I am going to join the ranks of those raving about your product. I have suffered my whole life with canker sores. People who don’t get them just don’t know how painful they can be. I have never found one product that helped me at all, other than pain relievers to take the edge off. My sister gave me the Canker Cover to try, and I wasn’t optimistic but tried it anyway. I expected pain and a horrible taste when I put it on, neither of which occurred. I slept through the night and from the time of placing the patch on I had ZERO pain. The next day it was almost gone. I was speechless. I went ahead and used one more patch that night just because I was afraid the remaining sore would stick to my tooth and worsen in the night. Today it is gone, and I can absolutely guarantee you it would have been at least another 10 painful days. – Diane”

In a previous study with 248 patients, the effectiveness of Canker Cover was compared to a ‘blank’, that is an oral patch with no active ingredients and to a control group that received no treatment. The study, showing similar results, was published in the Journal of Pharmaceutical Sciences (93:2927-2935).

Fifty-six million Americans get canker sores regularly, but teenagers and young adults get them most often, and women more frequently than men. Canker sores are shallow, painful sores on the inside of the lips, the inside of the cheeks, or on the gums. Without treatment, canker sores heal in 2 to 3 weeks. Nobody knows for sure what causes canker sores, although stress, vitamin B12 or iron deficiencies, menstruation, hormonal changes, and food allergies are all suspected. Common effects of canker sores include difficulty eating or even talking.

“Most canker sore products are simply topical pain relievers that numb the pain”, commented Dr. Ethan Schuman, a dentist based in St. Louis, Mo. “But, as anyone who’s ever had a canker sore knows, they work only moderately well and need to be reapplied constantly. There are liquids gels that form a film over the sore, but they don’t last very long and a good hot drink will make them melt. A few products contain anti-bacterial agents primarily used to prevent secondary infections, which are rare in any event. Of course, none of these products speed healing to any significant degree.”

Another user, Suzanne from Boston, agrees.” I frequently suffer from canker sores, so much so that I’ve been to the dentist about them. I developed a terrible sore on my tongue yesterday. It was so bad that I could hardly eat and couldn’t talk without lisping. I found Canker Cover at (my drugstore) and as promised, within minutes the pain was gone. I am also impressed at how well the patch adheres to the sore – I drank a hot cup of coffee 5 minutes after applying and it stayed firmly in place. Thank you so much for this wonderful, natural product. – Suzanne”

The 50-person study, which was published in the January, 2008 issue of Drugs in R&D, also showed that Canker Cover provided better pain relief, had fewer side effects (such as bad taste, numbing, tingling, etc.), caused no difficulty swallowing after application, and was easy to use.

Canadian user, Adam, was thrilled with his results.

“I bought your product, and followed the instructions. I was AMAZED with how effective your product is. I used “Canker Cover” on my mouth and felt immediate relief. I was surprised when I woke up the next morning to find that the sore had reduced by 75%. this was amazing for me, as normally my canker sores last for 3-4 weeks. As I am writing this email, I am enjoying the second dose. – Adam”

“The benefit to canker sore sufferers is quite clear”, said the new study’s primary author, Dr.Avner Shemer. “The oral patch heals canker sores in a day, stops pain and protects the sore from food and drink irritants for 8 – 12 hours at a time.”

Canker Cover is a tablet-like patch made from edible ingredients. It adheres to the canker sore within seconds and forms a clear, gel-like protective ‘seal’ that lasts 8 to 12 hours. The patch completely stops the pain, protects the sore from tongue, teeth, food, drink and other irritants, and won’t come off while eating. While on, the patch releases menthol, sea salt, citrus oil and other nutrients which prevent pain and speed the healing process. For most users, a single patch is all that is needed. As an added benefit, the patch keeps breath fresh. For more details, visit
