GUM Canker-X Pain Relief Gel Review

GUM Canker-X Pain Relief Gel is a topical gel used to treat canker sores. This review discusses the pros and cons of the gel.

GUM Canker-X Pain Relief Gel is an over-the-counter gel designed to relieve the pain suffered during canker sore outbreaks.

While the ingredients in GUM Canker-X Pain Relief Gel are not entirely “natural” the gel contains aloe vera, which has a soothing and healing effect on canker sores and mouth ulcers.

The main active ingredients in GUM Canker-X Pain Relief Gel is aloe vera, sodium hyaluronate, and Polyvinylpyrrolidone.

Although the GUM Canker-X Pain Relief Gel does not reduce the number of sore days or prevent canker sores from returning, it can reduce infection, pain, and temporary swelling in the mouth.

What is the difference between a canker sore and a cold sore?

There is some confusion over what the difference is between canker sores and cold sores. Both cold sores and canker sores appear near or in the mouth, and they both cause pain and swelling. However, the cause of each issue is significantly different, and the treatment for each condition is also different.

A canker sore is a mouth ulcer inside the mouth. It is not caused by a virus (although there is some scientific debate about this). Canker sores start as painful white blisters inside the mouth, that pop open a few days later, leaving a painful, red crater behind. Canker sores can take up to 15 days to fully heal and are quite painful while they remain.

While the exact cause of canker sores and mouth ulcers is unclear, they seem to occur most often when the pH balance of the mouth is off, or when a person is under higher stress than usual. Whether or not you suffer from canker sores may be genetic, or it may have to do with external factors, like diet, smoking, or the ingredients in a person’s oral hygiene products.

Cold sores, on the other hand, are viral. They are an outbreak of the HSV-1 virus, which about 80% of adults have, although not many adults have active outbreaks of cold sores.

Cold sores usually appear in the corner of the mouth as tiny, white blisters, that crack open and ooze, eventually scabbing over and healing.

Neither cold sores nor canker sores are dangerous to your overall health, but they are both painful, unsightly, and annoying.

Why Aren’t my Canker Sores Going Away?

Canker sores can pop up in anyone’s mouth, although they are more common in adults than children. Doctors don’t know if there is a cause for canker sores specifically.

Genetics, your overall health, and your stress levels are likely to play a role in whether or not you get frequent canker sore outbreaks. The following issues are often associated with canker sore outbreaks. However, this is not an exhaustive list of potential causes, and you may still get canker sores even if none of these causes are present in your life.


If you’re under a lot of stress, this can cause an upset in your mouth’s pH levels. The mouth is a part of the body that relies heavily on pH balance to fight bacteria and other invaders. When you are under stress and not sleeping enough, this can upset the delicate balance in the mouth, which could lead to a higher number of canker sore outbreaks.

Reduced Immune System

If you have a compromised immune system in some way, you are more likely to suffer from canker sores. This could be because your body has a harder time fighting off invading bacteria, which can damage your oral health in multiple ways.

Acidic Diet

Some canker sores can occur due to high levels of acid in the mouth. Smoking, drinking a lot of soda or juice, and eating acidic foods can cause a pH imbalance, potentially causing canker sores.

Vitamin Deficiencies

If you have low B vitamin and iron levels, you may have a higher risk of developing cold sores. These vitamins are important for your oral health. Ensuring your diet is high in these vitamins and minerals may help reduce the risk for canker sores.

Does GUM Canker-X Pain Relief Gel Cause Side Effects?

Since GUM Canker-X Pain Relief Gel is a topical treatment, there are few side effects. The gel does have a glue-like effect, so the biggest potential side effect is mouth irritation due to extended use.

Additionally, there are some compounds used in the gel that may cause an allergic reaction or irritation in the mouth. Check the full ingredients list carefully before using it to ensure the use of the gel is safe for you.

GUM Canker-X Pain Relief Gel and Mouth Ulcers

If you have frequent mouth sores, you may be a frequent user of GUM Canker-X Pain Relief Gel. Using the gel frequently is unlikely to cause problems, but it also cannot reduce your chances of getting outbreaks in the future. Instead of just using tube after tube of a topical gel, try these remedies instead.

Canker Sores Aren’t Healing

If your canker sores persist after 10 days, consult with a doctor. There may be an underlying reason for why your mouth sores aren’t healing faster.

Canker Sores Keep Returning

If you keep getting canker sores in an endless cycle, there may be something else going on. Avoid known triggers, like smoking, alcohol, sugar, and acidic foods, and consult with a doctor to see if something else could be causing your mouth ulcers.

Canker Sores Hurt More

If your canker sores hurt more after using GUM Canker-X Pain Relief Gel, gently rinse your mouth with warm water and stop using the gel.

What To Tell Your Doctor When Using GUM Canker-X Pain Relief Gel

Since GUM Canker-X Pain Relief Gel is a topical over-the-counter gel, there is no need to discuss the use of it with a doctor, unless your doctor has prescribed another topical or internal treatment to treat your canker sores.
