10. Infections: The Invisible Invaders of the Oral Realm
While most mouth ulcers are non-infectious in origin, certain microbial invaders can lead to these painful sores. Bacteria, viruses, and fungi, each have their own modus operandi, subtly undermining the oral environment’s defenses and paving the way for ulcers.
The herpes simplex virus, for instance, is a well-known culprit. Once it finds a home in the body, it can lay dormant, only to be activated by triggers like stress or sunlight, leading to the characteristic cold sores or fever blisters. Another intriguing player in this arena is the candida fungus. Thriving in moist environments, it can sometimes overgrow, especially in individuals with compromised immunity, leading to oral thrush and associated ulcers.
Bacterial infections, though less common, can also be at play. A disrupted oral microbiome, where harmful bacteria overpower the beneficial ones, can create conditions conducive to ulcer formation.
The battle against these microbial foes is ongoing. Our saliva, with its enzymes and antibodies, is the first line of defense, constantly neutralizing potential threats. Yet, sometimes, these invaders manage to breach these defenses, reminding us of their ever-looming presence. (10)
