There are different types of mouth sores. They can occur anywhere in the mouth including the bottom of the mouth, inner cheeks, gums, lips, and tongue.


Mouth sores may be caused by irritation from:

  • Trauma
  • A sharp or broken tooth or poorly fitting dentures
  • Biting your cheek, tongue, or lip
  • Burning your mouth from hot food or drinks
  • Braces
  • Chewing tobacco
  • Allergies

Cold sores are caused by the herpes simplex virus. They are very contagious. Often, you will have tenderness, tingling, or burning before the actual sore appears. Cold sores most often begin as blisters and then crust over. The herpes virus can live in your body for years. It only appears as a mouth sore when something triggers it, such as:

  • Another illness, especially if there is a fever
  • Hormone changes (such as menstruation)
  • Stress
  • Sun exposure

Canker sores are not contagious. They may look like a pale or yellow ulcer with a red outer ring. You may have one, or a group of them. Women seem to get them more than men. The cause of canker sores is not clear. It may be due to:

  • A weakness in your immune system (for example, from the cold or flu)
  • Hormone changes
  • Stress
  • Lack of certain vitamins and minerals in the diet, including vitamin B12 or folate

Less commonly, mouth sores can be a sign of an illness, tumor, or reaction to a medicine. This can include:

  • Autoimmune disorders (including Lupus)
  • Cancer of the mouth
  • Infections such as Hand foot and mouth disease
  • Weakened immune system — for example, if you have AIDS or are taking medicine after a transplant

Drugs that may cause mouth sores include aspirin, beta-blockers, chemotherapy medicines, antibiotics, sulfa drugs, and phenytoin.

What are the symptoms of an ulcer AKA Canker Sore in your Mouth? 

If you’ve been dealing with Mouth pain, you may have wondered if it could be a canker sore or an ulcer. 

Generally, stress or minor injury to the inside of the mouth is thought to be the cause of canker sores. Some types of trauma to the tissue of the mouth can cause a sore biting your cheek or tongue, and jamming your toothbrush in your gum is a good example of a trauma

Certain foods —including citrus or acidic fruits and vegetables (such as lemons, oranges, pineapples, apples, figs, tomatoes, strawberries) — can trigger a canker sore or make the problem worse.

Stress, trauma, or food are generally the most common causes of an ulcer in your mouth.

Let’s get into the warning signals that your body is going to be giving you to say  

Hey, we have a situation here.

One of the first things you might be experiencing is just some dull pain in your mouth. People who deal with chronic mouth ulcers also generally have weight loss ultimately because their mouth hurts so they’re not really consuming a whole lot of nourishment during those 7-14 days a mouth ulcer lasts, not wanting to eat because of the pain. 

You could absolutely experience swollen glands in the face and neck. And in that case, you may feel like your throat is sore too. When you do eat, you might also have difficulty swallowing. Especially if you have a sore in your throat. This is what I experienced with cancer treatments. The sores were so bad eating was something I just wanted to skip together, which then gave me a stomach ache because I was so hungry. I had to force myself to eat. It was a vicious cycle that went on for months until a friend brought me a product I had never heard of that changed my life. 

Several people who deal with ulcers also experienced a kind of indigestion with acid reflux types of symptoms. Again this was me. You might find that the pain in your stomach could subside when you eat or drink or use antacids. 

You might find when you have these sores you don’t chew as much because it hurts your mouth. Your mouth may not produce as much saliva to aid in processing and digesting the food in your stomach. 

So it’s going to show up as undigested when it comes on the other end. Another key thing,if you do actually have difficulty chewing when the sores are at their worst you can turn your food into a smoothie and drink it, through a straw.  Because you are not eating as much you may experience tiredness, fatigue, or just feeling kind of off. Even before I was diagnosed with cancer I would get sores in my mouth every couple of weeks. I explained them away. It was because I was in a hurry when chewing my food, biting my tongue and my cheeks or It was because of the acid in my stomach not eating right. Turns out I had a chronic acidic environment in my mouth and my stomach. A ph imbalance can contribute to cavities and some cancers. 

Those are also other warning signals that your body could give you.  Mouth ulcers could be a warning sign you have bigger issues!  

I’m curious, did you know that you could experience all of those different types of symptoms as the result of a mouth ulcer? Let me know your thoughts in the comments below. 

There are many over-the-counter remedies for mouth pain and ulcers. Some work some don’t and I have tried them all over the past 30 years. The best solution for me was a dental laser. It took away the pain immediately and healed the sores completely in two to three days. It worked like magic. In fact, it was like magic you just wave the laser over the sore and abracadabra.

The laser was and is amazing. I would drive an hour for relief. The laser did not stop them from coming back though.

Okay, it’s time I need to share with you that method for ending ulcers once and for all.

The key is knowing not only what causes them, but ultimately everything else that’s going on in your body. 

What was going on with your system that was able to happen in the first place? And we come in contact with all different kinds of microbes all the time. 

It’s only when something’s not working right within our immune system, which then the question becomes why is the immune system not working right? If you are not testing you are guessing as my dear friend Dr. Kelly Shockly Says!  I get that not everyone can afford to get tested. Insurance does not usually cover this.

I am grateful I found Theragel. It is a wound-healing gel, it is an all-natural plant-based and safe to swallow for all ages. This product changed my life when it comes to mouth sores. It soothes the sores and gets to the ones the laser can not reach down my throat because it is safe to swallow. I now use it twice a day, just a teaspoon full, swish, and swallow. I don’t always swallow it, sometimes I spit it out. 

Since I started using it regularly twice a day I no longer get sores in my mouth at all. In the past 10 months of using it, I have had two sores, one from a Christmas ornament hook. Which did not last as long or was as painful as it would have been if I did not have this product. The other time I had stopped using Thergel for a week due to an allergic reaction to a medication. I stopped all supplements until I could figure out the cause of the breakout.  I ended up using the Theragel on my body as a lotion on the itchy sores. That is not its intended purpose, not what the FDA approved it for,  but it worked. I would have tried anything at that point. So I am sharing this product because it has made a difference to my very sensitive body since having cancer. It has made a difference in my family,  friends, and patients’ lives as well. 

How could I keep it to myself? It works so well I became a wellness partner to spread the word about how well it works. Try a bottle for yourself. If you are in as much pain as I was $35 will be worth it.
