Oral Health and Kidney Disease

Special considerations for those with kidney disease.

The link between oral health and overall health

Research increasingly suggests that oral health and overall health are closely related. Poor oral hygiene, and the inflammation that accompanies it, have been linked to a number of major health issues.

With poor oral home care and/or a lack of professional dental cleanings, bacteria in the mouth can multiply and grow. It may spread to other parts of the body, especially if your immune system is weak.

The body may respond by attacking healthy tissues and organs, which can lead to serious issues, including hospitalization and death.

Oral health and kidney disease

If you have kidney disease, are on dialysis or are a kidney transplant recipient or candidate, be sure to tell your dentist. Good oral health is especially important in these circumstances. Consider the following:

• People with kidney disease have weakened immune systems and are prone to experiencing infection.
• The calcium imbalance attributed to kidney disease can weaken bones and cause bone loss in the jaw. This can result in loose teeth and potential tooth loss.
• Some dialysis treatments include the use of blood thinners, which can cause bleeding issues during dental treatment. In general, dental appointments are not recommended on dialysis days.
• Talk to your kidney doctor when a dental treatment is planned. Your doctor may want to prescribe a pre-procedure antibiotic to reduce the risk of infection.
• Drugs used to treat kidney diseases may cause dry mouth. This increases your risk of cavities and gum disease. To reduce your potential risk, chew sugarless gum or suck on sugarless candy to increase your saliva. Over-the-counter saliva substitutes can also help.

Oral health and kidney transplants

A dental exam is required as part of the kidney transplant evaluation process. Oral infections from severe tooth decay or gum disease can delay or prevent a person from being approved for a transplant.

Prevention is key!

• Brush twice daily with a soft-bristled toothbrush and, ideally, floss once a day. Be thorough and take your time.
• Visit your dentist for exams and cleanings at least twice per year.
