What is Frontier Pharmaceuticals Cankers Away?

Frontier Pharm Cankers Away canker sore treatment is a product which promises immediate and long-lasting pain relief for canker sores and other oral lesions. The manufacturer claims it contains natural ingredients and comes with a pleasant lemon-like flavor. It also alleges that its effectiveness has been demonstrated by a double-blind, placebo-controlled, multicenter FDA Phase II clinical study. Additionally, it asserts that it reduces irritation caused by orthodontic appliances and teething.  It can also be used be used to treat lesions caused by AIDS, chemotherapy, and radiation.

Frontier Pharmaceuticals Cankers Away comes in the form of a liquid in pre-filled swabs with fast and easy steps to apply.  It should be used topically using a pre-filled cotton swab. It doesn’t leave an uncomfortable residue in the mouth, and you can resume normal eating immediately after use. For complete cessation of pain and to start the healing process, only 1 or 2 applications are required. We didn’t find the appropriate time of the day that one should apply this product.


At the time of our review, a pack of Cankers Away with 12 pre-filled swabs was being sold for $14.67, marked down from $16.30 on the manufacturer’s official website. If you purchase four packs, each pack will cost $13.86. The manufacturer doesn’t advertise a monthly subscription.

The Bottom Line

Cankers Away seems as if it may be useful when it comes to dealing with canker sores and other oral lesions. It contains ingredients that the manufacturer claims have been demonstrated to be effective in reducing oral irritations. We have not come across any adverse side effects associated with its use. Nonetheless, the lack of user reviews or comments is an indication that this is not a widely used product. Additionally, the manufacturer’s return policy appears complicated if it may take up to 30 business days to get a refund. The manufacturer’s claim that you should only require 1 to 2 applications to relieve pain, yet the smallest pack comes with 12 pre-filled swabs which means that you may have quite a bit of unused product left over.
