While researching a range of ulcer treatments, we came across Bye Mouth Ulcer, a film-forming gel. Read on for our review of the product’s formulation and benefits.

What is Bye Mouth Ulcer?

Bye Mouth Ulcer is a gel intended for the treatment of ulcers and small wounds within the mouth. The manufacturer says its gel formulation forms a protective layer around the sore and alleviates the pain. The gel does not contain anesthetic, nor does it have acidic properties; it supports the healing process naturally.


The ingredients in Bye Mouth Ulcer have, according to the maker, been clinically proven to cure ulcers and sores in the mouth, to soothe the pain and protect the affected area from further irritation. The ingredients are as follows:

  • Dimethicone
  • Aerosil
  • Hydroxyethylcellulose
  • Cinnamon oil
  • Povidon
  • Crospovidon
  • Al-Mg-Silicate
  • Aqua
  • Sodium Methylparaben
  • Colourant


The manufacturer provides detailed directions for effective use of this product. The gel should be applied either 30 minutes before mealtime or directly afterwards. You must wash your hands before applying the gel using your finger. Recommended usage is three to four times a day, until the ulcer disappears.

Once the gel has been spread across the sore area, refrain from eating or drinking anything for at least 30 minutes.


A 15ml tube of Bye Mouth Ulcer is available at a variety of online stores. While it is available for $18.83 on Amazon, the price will vary depending on the outlet you buy from.

Possible Side Effects

While Bye Mouth Ulcer doesn’t appear to have any side effects, we did come across a number of cautionary tips for using this gel. The manufacturer cautions users to consult a physician if the ulcer doesn’t disappear within 2 weeks of the start of treatment with By Mouth Ulcer or if users experience an aggravation of the ulcer or a fever.

It is best to keep the gel out of reach of children less than 3 years old, as its effects on such young children have not been researched.

Manufacturer’s Commitment

We were unable to find any information regarding a money back guarantee. This may deter some potential buyers from purchasing this gel, as it seems they have to assume all the risk of trying the product.

The Bottom Line

The bottom line is that Bye Mouth Ulcer is said to cure mouth ulcers and other mouth wounds and sores. The detailed instructions supplied by the manufacturers and the use of clinically proven ingredients are positives that cannot be ignored. However, we must highlight the lack of a money-back guarantee, as it might discourage some users.
