Healthy Immune System
As we noted above, fighting the chronic inflammation in the mouth puts your immune system at a constant state of alertness. This reduces the readiness of your immune system for dealing with new threats.
However, the risks are even more serious, because oral bacteria have methods of subverting your immune system. Sometimes, oral bacteria release compounds that “blind” your immune system to threats. This means they can’t see the oral bacteria, but it might also make it harder for them to detect other threats, such as cancerous cells.
In extreme cases, oral bacteria can even convince your immune cells to attack your body, causing autoimmune diseases. This has been documented in the link between gum disease and rheumatoid arthritis, where your immune system attacks your joints.
Keeping oral infections under control helps keep your immune system fit for fighting other infections in the body.
