ST. Worms in the Mouth: The Terrifying Reality of Oral Myiasis That Few People Know About

Oral myiasis may sound like something from a horror film, but it is a real and documented medical condition. It occurs when fly larvae develop inside the human mouth. Though extremely rare, cases have been reported worldwide, particularly in regions with poor sanitation and heavy fly exposure.

The condition begins when certain flies deposit eggs in moist or damaged areas of the mouth. Gum disease, open sores, rotting teeth, or the inability to close the mouth during sleep can create ideal conditions for infestation.

Once the eggs hatch, the larvae burrow into soft tissue. They feed on food residue, dead cells, and sometimes living tissue, allowing the infestation to expand quickly and cause serious discomfort or damage.

Early symptoms often include swelling, excessive saliva, pain, and a disturbing crawling sensation. Some patients experience bad odors or tastes, and in severe cases, the larvae can be seen moving inside the mouth.

Contrary to common belief, contaminated food is rarely the cause. Most cases occur when flies come into direct contact with the mouth of someone sleeping, unconscious, elderly, or unable to maintain proper hygiene. Weakened immunity and severe dental issues increase risk.

Treatment requires careful removal of each larva, often under anesthesia. Medications may be used to eliminate hidden larvae, followed by thorough cleaning and possible dental or surgical repair.

Prevention is simple and effective. Good oral hygiene, clean living conditions, and fly control greatly reduce risk. While deeply unsettling, oral myiasis remains very uncommon, especially among healthy individuals.
