Here are the ingredients for DenTek’s Canker Cover:

  • Menthol 2.5 mg which is the active ingredient to provide pain relief

This is meant to be used by adults and children that are over 5 years old. Pat the sore dry with a tissue if you can. Place one of the canker covers on a clean dry finger with the white side up. Place it directly onto the sore and hold it there for at least 20 seconds. If the sore is in a hard to reach area near the gums or teeth you can use half of the patch. In 30 minutes the patch should dissolve into a clear and gel-like bandage. You can apply up to 3 patches a day. However, the manufacturer states that only one is usually needed.

Possible Side Effects

You may experience some discomfort with the patch. If it persists, gently remove the patch by adding warm water to its edges. Immediately stop using it if you experience an adverse reaction or if symptoms still persist after 7 days and see your physician. Women who are pregnant, nursing, or someone who is taking a prescription medication should first consult with a doctor before use.
