Rheumatoid arthritis: gum disease affects the microbiome and increases symptoms
Researchers have long speculated that autoimmune diseases such as rheumatoid arthritis (RA) are likely to be caused by, or caused by, microorganisms.
Links between periodontal disease and changes in the oral and gut microbiome and RA have been recognized, but exactly what connects them all has not been discovered.
Several studies seem to show that the oral microbiome may play a role in the development of rheumatoid arthritis.
One study highlighted three types of anaerobic bacteria that occur in the oral cavity that were identified in the joint fluid of people with RA.
Another analysis showed that antibodies to certain types of bacteria are linked to gum disease and may play a role in the development of rheumatoid arthritis.
