9 Causes of Mouth Pain You Should Know About

By Susan E. Sklar, M.D.
The first time I met Anna, she complained that mouth pain was not only interfering with her ability to enjoy the foods she loved, but with her ability to sleep and even enjoy life. She suspected that she had Burning Mouth Syndrome, based on her symptoms and what she had read online, and she was afraid that she might have a long journey ahead before she could return to cooking for her family again.

On further examination, however, we found that Anna did not have Burning Mouth Syndrome at all.

Over the course of several visits, I found that she often noticed symptoms of reflux on first waking up in the morning, regardless of what she had eaten before she went to bed. Once we identified the reflux she suffered overnight, we were able to treat those symptoms, and the burning pain her mouth went away along with it.

Ongoing mouth pain can cause serious complications in many areas of your life. Many victims with mouth pain struggle to reconcile their symptoms and live normally. If, like Anna, you’re suffering from ongoing mouth pain, you may worry about Burning Mouth Syndrome and other serious disorders. The truth is, however, there are many conditions that can issue similar symptoms, including conditions that are far easier to treat than Burning Mouth Syndrome.

A Look at Burning Mouth Syndrome

Burning Mouth Syndrome is defined as a burning sensation that occurs without any obvious reason. Burning Mouth Syndrome patients do not have identifiable oral lesions like sores in the mouth. They often do not have laboratory findings that explain their pain. Pain from burning mouth syndrome gets described several ways:

  • Burning
  • Tingling
  • Tender
  • Hot
  • Scalding
  • Numb

Often, multiple sites in the mouth are involved. The most common areas impacted by Burning Mouth Syndrome, however, are the front two thirds of the mouth and the tip of the tongue.

If you have symptoms of burning mouth syndrome, hormonal treatments can help restore your quality of life and relieve your pain. However, Burning Mouth Syndrome is not the only cause of oral pain. Ruling out and/or treating other symptoms can make it easier for you to address your mouth pain. Consider these symptoms when determining whether you might have burning mouth syndrome.

1. Do you have a white coating on your tongue?

Oral yeast, also known as thrush, is a fungus that coats the mouth and tongue.  It often causes burning or pain. The yeast that causes thrush, also known as Candida, occurs in many areas of the body naturally. In fact, it normally gets found in the mouth. However, yeast overgrowth can cause symptoms of thrush.[1]

The most noticeable symptom of thrush is white patches on the cheeks, tongue, and roof of the mouth. However, patients may also notice redness, swelling, or a cotton-like feeling in the mouth. Patients may notice an increase in pain when eating or swallowing. They may also notice a loss of the sense of taste. If you have these symptoms alongside the burning pain in your mouth and/or throat, it could be a sign of thrush. Luckily, there are many medications that can quickly and easily treat this condition. You will need to see your doctor to get a prescription for thrush.

In the future, proper oral health, avoiding smoking, and rinsing the mouth after using corticosteroids can all decrease your risk of developing a thrush infection.

2. Are there tiny blisters in your mouth or tongue?

Viral infections, including herpes[2] and shingles, can cause burning pain like what patients experience with burning mouth syndrome. Most often, these viral infections present with tiny blisters in the mouth that cause burning pain when touched or when you eat. You may also notice ongoing pain from some of these blisters.

Most often, patients get oral herpes by kissing or engaging in oral sex with someone who has an active outbreak. Most of the time, herpes is not transmitted when the patient does not have an active outbreak. However, once you have it, it can recur regularly, especially during periods of stress. Usually, the initial outbreak is the worst. It can include fever and severe headache along with the sores. Later outbreaks usually include mild sores around the lips.

Your doctor can diagnose oral herpes with a quick swab test. Usually, the sores associated with oral herpes heal within four to six days. However, some patients may take longer for their sores to heal. If you have questions about your herpes infection or the pain interferes with your daily activities, see your doctor. Antiviral topical ointments or medications can help relieve your symptoms and clear up the infection faster. You may also use topical anesthetics or anti-inflammatory medications to help reduce the immediate symptoms of your outbreak and relieve pain.

3. Do you have lacy white patches in your mouth or on your tongue?

Lichen planus, an autoimmune disease, can cause painful white patches and sores. It usually appears as lacy, slightly raised white patches, but may also appear in a rectangular pattern. Lichen planus can impact not only the mouth, but also the esophageal and vaginal mucosa. Some scientists believe that lichen planus may be caused by an autoimmune disorder in which the body’s white blood cells attack these tissues, but they need more research before determining definitively what causes these conditions. In severe cases, lichen planus may cause ulcers in the mouth. Patients who have mouth ulcers may experience pain even when they aren’t eating or drinking.

Treatment for lichen planus[3] may begin with management, including using a soft toothbrush and mild toothpaste. This condition requires ongoing treatment to keep it as manageable as possible. However, by naturally dampening the overactive immune processes[4], you may be able to reduce many of the symptoms of this disorder. If you have lichen planus, a doctor that specializes in hormone management can help you moderate your hormones, control that immune response, and improve your quality of life.

4. Do you have mouth sores?

Bechet’s disease[5] is another autoimmune disease that can affect many organs in the body. Mouth sores occur commonly in patients with Bechet’s disease. These sores, called aphthous ulcers, can occur throughout the mouth: on the cheeks, tongue, roof of the mouth, lips, and even tonsils. Most of the time, individual sores heal within a couple of weeks, but they can reoccur. These painful canker sores often appear as the first sign of Bechet’s disease, and may serve as an identifying marker as doctors work to find a diagnosis.

In order to address Bechet’s disease, your doctor will work to help manage symptoms, including potentially using a mouthwash designed to provide numbness and reduce pain in those mouth ulcers. To resolve treatments, you will need to dampen the overactive immune response.

5. Do you have dry mouth? Do you have dry eyes? Have you been diagnosed with an autoimmune disease?

A feeling of dry mouth is quite common with Burning Mouth Syndrome. With Burning Mouth Syndrome, however, actual production of saliva remains normal. If you have low salivary flow, you may have an autoimmune disorder called Sjogren’s disease. Due to its impact on the exocrine glands, including the salivary glands, Sjogren’s disease may cause:

  • Dry mouth
  • Dry eyes
  • Diminished taste and smell
  • Decreased saliva production
  • Arthritis symptoms

If you have Sjogren’s disease[6], you may notice that you need water or another liquid to help you swallow dry food, even when you should be able to swallow it on your own.

Treatment begins with topical therapy designed to help treat eye and mouth symptoms. Failure to address these symptoms could lead to more severe complications, including further loss of taste and smell and vision impairments. Sometimes, doctors recommend systemic treatment that can help address all the symptoms associated with the disorder. Sjogren’s disease can be diagnosed with a blood test.

6. Do you have gastrointestinal reflux or laryngeal pharyngeal reflux?

If you have reflux[7], it can cause the acidic contents of your stomach to backflow into your esophagus and larynx. This, in turn, can cause burning to the throat, mouth, and tongue, since these tissues are not intended to deal with such acidic contents. Reflux can occur for a variety of reasons, including food sensitivities or breathing problems during sleep. Sometimes, you may not notice the symptoms of reflux while you are awake, or you may wake up noticing burning sensations on the stomach and tongue.

Diagnosing any underlying conditions, including allergies or sleep problems, can help you address the cause of your reflux[7] and get relief. In the meantime, you can take medications that will decrease the acid in your stomach and protect those sensitive tissues, decreasing the burning sensation. Your doctor may recommend making some dietary changes, including avoiding highly acidic foods when possible.

 7. Are you on blood pressure medications?

Blood pressure medications are intended to address underlying high blood pressure symptoms. Unfortunately, they can also bring significant side effects. Some people find that blood pressure medications[8] can cause symptoms that mimic those of burning mouth syndrome. Specifically, the ACE (angiotensin-converting-enzyme) inhibitors seem to cause this problem in some patients. The medications known to cause this problem end in “pril” and have names like lisinopril or captopril. A change to another medication solves the problem for many people.

Any time you have new or unusual symptoms after starting a new medication, you should discuss these issues with your doctor. This especially applies if the symptoms cause problems that interfere with your daily functions or sleep. Burning pain in your mouth should be addressed quickly before those symptoms grow worse.

8. Do you have diabetic neuropathy?

Many patients with diabetes notice a number of symptoms that seem, at first, to be unrelated to their diagnosis. Diabetes can cause nerve damage[9] due to high circulating blood sugars.  This damage usually affects the feet and legs with numbness and burning.  However, the tongue can be involved in the burning pain. Patients may notice intense, burning pain in the mouth or discover a loss of taste and burning sensation.

If you have burning mouth syndrome associated with diabetes, talk to your doctor as soon as possible. A change in medications, better blood sugar management, or a change in your diet can help address those symptoms. When your diabetes is well-managed, you will be less likely to have symptoms of nerve damage, including burning pain the mouth related to your diabetes.

9. Do you get a red line when you scratch your arm with your fingernail?

When most people scratch their arm lightly with a fingernail, the scratch quickly turns white, with relatively little evidence left behind. A red line when you scratch could indicate the activation of mast cells in the skin. Mast cells release histamine and cause redness and swelling that can occur with light contact.

Some authorities believe that mast cell activation[10] can also cause pain and burning in the mouth. For these patients, antihistamines can help treat the burning sensation. Mast cell activation may also cause symptoms like:

  • Rapid pulse
  • Low blood pressure
  • Passing out unexpectedly
  • Itching
  • Hives
  • Swelling
  • Skin redness
  • Wheezing
  • Shortness of breath
  • Diarrhea and vomiting

Mast cell activation disorder can be diagnosed through a blood test. Treatment may include antihistamines, corticosteroids, and aspirin, among other options. As with many other syndromes, the goal is treating the symptoms and alleviating patient suffering as much as possible.

Do You Have Burning Pain in the Mouth or Other Symptoms of Burning Mouth Syndrome?
