The human body is a complex structure made up of interconnected systems that depend on each other. As a result, different parts of our bodies can have a direct effect on others—sometimes good and sometimes bad.
This fact can be particularly true for people with kidney disease. While kidney disease's primary concern is a collapse of your renal system’s ability to filter wastes from your blood, it can also affect other areas of your body, including your mouth.
Like many other diseases, researchers have found several connections between kidney disease and oral health. Because of this, it's essential for people with kidney disease to take extra care of their oral hygiene to avoid developing new or worsening symptoms.
If you've been diagnosed with kidney disease, you may be more likely to develop:
Dry Mouth – According to the Journal of the American Dental Association, more than 500 medications can cause dry mouth, including drugs used to treat kidney disease. A dry mouth can be generally uncomfortable for many, can cause difficulty when eating or drinking, and may lead to bad breath. Your mouth uses saliva to clear away food and harmful bacteria from the surface of your teeth, so people with dry mouth may be at risk for tooth decay.
Oral Lesions – An oral lesion is a mouth ulcer, sore, or open wound found on the mucous membrane of the oral cavity. When performing checkups, dentists often check for oral lesions because some may present the risk of transforming into oral cancer if left untreated. A study conducted by BMC Oral Health found that those with chronic kidney disease (CKD) have a higher instance of oral lesions than those without CKD.
Periodontitis – More commonly known as gum disease, periodontitis is a severe infection that spreads beyond the gum line and can destroy the bone tissue supporting teeth, sometimes leading to tooth loss. A study conducted by the Pakistan Journal of Medical Science found that patients with CKD have “higher prevalence of periodontal disease” and that there’s “a bidrectional relation between CKD and periodontal disease.” What you can do – You can prevent the progression of gum disease by adhering to better oral hygiene habits at home, such as following your doctor's recommendations for brushing and flossing and avoiding smoking.
Kidney disease and your oral health can affect each other, which is why it's important to talk with both your physician and dentist when it comes to upcoming procedures. Because a weakened immune system is a symptom of both kidney disease and treatment for kidney disease, individuals are more susceptible to infections that can occur during and after dental procedures. Doctors can help by prescribing antibiotics that help fight infection. Lastly, be sure to bring a list of medications you're taking to your dentist prior to any procedure.
Individuals diagnosed with kidney disease have a greater risk of developing oral health issues like those listed above. Therefore, it's important to practice a preventative oral health routine, including:
