Autoimmune Series Part 3: How Inflammatory Bowel Diseases can affect Oral Health

September 12, 2019

 

Inflammatory bowel diseases (IBD), are a group of autoimmune diseases that result in chronic inflammation in the gastrointestinal (GI) tract. The two main diseases identified in this group are Crohn’s Disease and Ulcerative Colitis. Due to the chronic inflammation eventually damaging the GI tract, the resulting symptoms are painful.

IBD can affect any portion of the GI tract

There are a few differences between these two diseases, but both must be diagnosed by a physician. Crohn’s disease can take place anywhere along the GI tract, from the mouth to the anus. The most common area targeted is in the small intestine, just before the colon (ileum). These areas affected show up as patches of irritation next to healthy tissue and the inflammation may reach through multiple wall layers within the intestine. Conversely, Ulcerative Colitis is localized to the colon and rectum. Unlike the patchy areas seen in Crohn’s, the damaged areas in Colitis are seen in a continuous pattern, typically moving upward from the rectum to the colon. Colitis is also only found in the innermost wall  of the colon as opposed to affecting multiple layers.

Like most autoimmune diseases the etiology of IBD are not well known. Research points to environmental and genetic factors as the likely causes. The result is an immune response that when triggered by environmental factors attacks the cells in the GI tract. The symptoms of IBD are similar between both Crohn’s and Colitis and can be misdiagnosed. 

Symptoms:

-Persistent diarrhea
-Abdominal pain
-Rectal bleeding/bloody stools
-Weight loss
-Fatigue

IBD are different from, IBS and Celiac disease. The similarity in symptoms can cause misdiagnosis which is why it’s important to seek a physician are a correct diagnosis and treatment. Now that we know how IBD affects our gut, how can it affect our oral health? IBD can have several oral manifestations:

-Xerostomia (Dry Mouth): The salivary glands don’t produce enough saliva to keep the mouth moist and the pH of the oral cavity balanced. This can result in rampant decay.

IBD may cause aphthous ulcers in mouth.

Painful aphthous ulcer on inner lip. These can be a result of IBD.

-Aphthous Ulcers: Also known as canker sores. Individuals with IBD may present with frequent or multiple ulcers. These lesions can make oral care more uncomfortable.

Mucosal Tags: Similar to skin tags, these can be seen as a result of Crohn’s Disease. They may appear on the inner cheek, and can be visualized by your dentist or hygienist. 

-Gingivitis: Reversible form of periodontal disease, is treated with good home care and professional hygiene visits. 

Depending on which manifestations you’re experiencing your doctor and hygienist will tailor a treatment plan that best suits your needs. For example, if you’re experiencing frequent aphthous ulcers you may be prescribed a steroid cream to decrease length and frequency. Or if you suffer from xerostomia, we’ll discuss options to balance pH and decrease your risk for decay. As with all autoimmune diseases, the healthier we can keep your mouth the less effect it will have on your immune response. If you would like to discuss the impact your IBD may be having on your oral health, please feel free to mention it at your next visit!
