Rheumatoid arthritis and oral health problems

Patients with RA can experience problems with their mouths. Some are directly related to RA such as gum disease, jaw problems and dry mouth and some indirectly, e.g. as a result of RA medication or difficulty cleaning teeth.

Introduction 

The mouth plays an important role in the functioning of the human body; teeth chew food into smaller pieces to make it more digestible, and saliva contains enzymes which further break down food. Saliva also helps prevent oral infections and is required for swallowing.

Teeth are held in place in the jaw bone by support from the surrounding gums and ligaments (fibrous tissue), making gum health very important too. From an appearance point of view, having a nice smile can boost a person’s confidence.

Rheumatoid arthritis patients can experience problems with their mouths. Some oral health problems such as gum disease, jaw problems and dry mouth (i.e. lack of saliva) are directly related to RA. Dry mouth, for example, is a symptom of the autoimmune condition Sjögren’s syndrome, which is common in people with RA.

Some oral health problems are indirectly related to RA, for example a result of RA medication or difficulty with cleaning the mouth (due to problems with joints). This will not be a problem for all people with RA, but it may be helpful to be aware of these potential problems so that you know what to look out for and what you might want to discuss with your dentist.

Dentists, dental therapists and dental hygienists can help with assessing and treating mouth problems as well as giving advice on how to keep your mouth healthy.
