Red Spots in the Mouth

Autoimmune causes

Many inflammatory conditions that result in the body attacking itself can also affect the mouth and cause injury and inflammation that results in red spots or sores.

• Systemic: Systemic autoimmune conditions that affect multiple body parts such as inflammatory bowel disease and lupus often have symptoms that affect the mouth.
• Dermatologic: Many dermatologic conditions can result in chronic, inflammatory rashes or lesions that prefer the mucosal linings of the body, including the mouth. Conditions such as lichen planus can cause red spots in the mouth that persist and are difficult to treat.

Environmental causes

Environmental causes can be related to certain exposures or lifestyle habits.

• Diet: The mouth is in direct contact with food and liquids that may cause allergic reactions that result in red lesions in the mouth. Foods that seem to be particularly common allergens or irritants include those that are spicy or acidic like oranges, eggs, strawberries, and even chocolate. On the other hand, diets deficient in certain nutrients such as vitamin B12, folate or iron can also result in red spots or sores in the mouth.
• Drug use: Tobacco and alcohol can cause significant irritation of the mouth and its structures and even some types of cancer. In fact, tobacco products are heavily associated with oral cancer. Tobacco and alcohol can cause excess cell growth in the mucosal lining of the mouth due to chronic irritation and result in painful sores. Mouth sores are also a side effect of chemotherapy.
• Stress: Fatigue and emotional stress can also be a strong trigger for the development of red spots or sores in the mouth. Take note if you develop spots in your mouth during stressful times.

Cancer

• Acute lymphoblastic leukemia is also called acute lymphocytic leukemia or ALL. It is a cancer that starts in the bone marrow where new white blood cells, or lymphocytes, are formed.
• Mouth sores are a common side effect of cancer treatment such as chemotherapy or radiation therapy. It can cause red areas or a burning feeling in the mouth, painful sores, and painful or difficulty swallowing.

Are there things I can do to prevent the development of red spots in the mouth?

Since many of the causes of red spots in the mouth are infectious in nature, it is important to protect yourself from pathogens by maintaining proper hygiene such as hand washing. Avoid putting your hands in your mouth especially after touching doorknobs or interacting with sick individuals. In addition, maintaining proper nutrition and avoiding tobacco and alcohol can also go a long way in preventing the occurrence of red spots in the mouth.

Are red spots in the mouth dangerous or life-threatening?

For the most part, red spots in the mouth are more annoying and uncomfortable rather than dangerous or life-threatening. However, a red spot in your mouth may also be a sign of a cancerous process, so never ignore your symptoms. It is always important to follow up on your symptoms since many of the underlying conditions often require follow-up and treatment.

How long will the red spots in my mouth last?

The duration of your symptoms will depend on the specific cause. For example, bacterial causes of red spots in the mouth often go away with the resolution of the underlying bacteria whereas autoimmune causes of red spots in the mouth may be a lifelong problem.

Are red spots in the mouth an acute or chronic condition?

There are some cases in which red spots in the mouth can be chronic, especially those associated with autoimmune conditions like inflammatory bowel disease. Furthermore, viruses such as herpes can persist within the body and recur in times of physical and emotional stress. Red spots related to chronic habits such as tobacco and alcohol may also persist and become chronic whereas bacterial infections are more acute.

Can red spots in my mouth spread to other parts of my body?

Red spots in the mouth can spread or appear on other parts of the body depending on the cause. For example, infectious causes ranging from bacteria to fungi can cause spots to appear not only in the mouth but also in areas such as the genitalia and under the armpits.
