This triple action remedy also claims to relieve pain and soothe sores without causing any burning or stinging. Read on to learn more about Sunstar GUM Canker-X Gel.


Sunstar GUM Canker-X Gel contains:

  • Aloe Vera- This ingredient plays a significant role in soothing sores.
  • Sodium Hyaluronate- The role of this ingredient is to hydrate sores.
  • Polyvinylpyrrolidone (PVP)- It forms a thin protective layer to promote healing and relieve pain for hours.
  • Water
  • Maltodextrin
  • Sodium benzoate
  • Propylene glycol
  • Castor oil
  • Potassium Sorbate
  • Xanthan gum
  • Saccharin Sodium
  • Disodium edetate
  • Benzalkonium chloride
  • Glycyrrhetinic acid


The gel should be applied directly to the canker sores as often as possible. You should apply one to two drops to cover the entire sore. Use a clean finger or a cotton swab to apply a thin layer of the gel on the affected parts and make sure that your tongue does not touch the sore for two minutes after applying the gel to enable a protective layer to form. Moreover, do not drink or eat anything for an hour in order to achieve best results.

In summary, Sunstar GUM Canker-X Gel claims to have a strong formula for healing mouth ulcers and canker sores. This claim is mainly based on the use of aloe vera as an active ingredient. Although this product has some positive features, we find it difficult to recommend it because of the information we have gathered during the writing of this review. One of the factors that might attract consumers to purchase this product is the money-back guarantee offered by the manufacturer, as it assures consumers that this product is effective. The affordable price is also another benefit associated with this product.
