Mouth larva, a term commonly used to describe oral myiasis, is a rare but concerning condition caused by the infestation of fly larvae in the mouth. This condition can lead to significant discomfort and health complications if not treated promptly. In this article, we will explore what mouth larva is, its symptoms, causes, and risk factors, as well as prevention methods and effective treatments. We will also discuss the specific treatment for oral myiasis and the role of health insurance in covering such conditions.
What is mouth larva?
Mouth larva, or oral myiasis, occurs when fly larvae infest the tissues of the mouth. These larvae, also known as maggots, typically belong to species such as Cochliomyia hominivorax or Chrysomya bezziana. The infestation usually happens in individuals with poor oral hygiene or compromised health, leading to the larvae feeding on the necrotic tissue. Oral myiasis can result in severe pain, swelling, and even tissue destruction if not treated promptly.

How do mouth larvae appear?
Mouth larvae, also known as oral myiasis, appear as small, worm-like parasites that infest the oral cavity. They typically enter through open wounds or poor oral hygiene, often appearing in decayed tissue or gums, causing irritation, pain, and infection.
What types of food do mouth larvae eat?
Mouth larvae primarily feed on necrotic tissue, blood, and decaying organic matter within the mouth. In cases of oral myiasis, these larvae thrive on dead tissue in the gums, teeth, and open wounds, further aggravating the affected area by consuming unhealthy tissue.
What is the life cycle of Mouth Larvae?
The life cycle of mouth larvae involves several stages: eggs are laid by adult flies, hatch into larvae, which feed on decayed tissue, then develop into pupae before becoming adult flies. The entire cycle takes a few weeks, with larvae causing the most damage.
What are the types of mouth larva?
Mouth larva refers to larvae from various fly species that can infest human oral cavities, a condition known as oral myiasis. The most common types of larvae found in the mouth belong to the species of Cochliomyia hominivorax (screwworm fly), Chrysomya bezziana (Old World screwworm), and Sarcophagidae (flesh flies). These larvae infest the soft tissues of the oral cavity, leading to swelling, pain, and damage to tissues, requiring immediate medical intervention.
Mouth larvae, or fly larvae, can infest oral tissues, particularly in tropical regions. Here are the common types:
1. Screwworm Fly Larvae:
These larvae burrow deep into the oral tissues, leading to significant infections and extensive tissue damage. Unlike many other species, they primarily feed on living tissues, making them particularly dangerous. Immediate medical intervention is critical to prevent further complications.
2. Botfly Larvae:
Botfly larvae can infest human tissues, including the mouth. When lodged inside, they cause painful swellings, irritation, and ulcers. These parasitic larvae require surgical removal and can result in long-lasting discomfort if not treated promptly.
3. Tumbu Fly Larvae:
These larvae usually enter the body through open wounds and can infest the oral cavity. They are often contracted through contact with infected animals or contaminated environments, causing discomfort and requiring medical removal to prevent infections.
Where do mouth larva live?
Mouth larvae typically inhabit decaying or necrotic tissue within the oral cavity, particularly in people with poor oral hygiene or those suffering from dental infections, wounds, or diseases. They thrive in moist environments, feeding on decomposing tissues and waste, which is why they are often found in unsanitary conditions.
Why do people get oral larvae or oral myiasis?
Oral myiasis occurs when larvae infest the mouth, often due to poor oral hygiene, untreated dental conditions, or open wounds in the oral cavity. People living in tropical and subtropical regions, particularly in areas with poor sanitation, are more prone to this condition. Flies are attracted to open sores, wounds, or decaying tissues in the mouth, laying their eggs, which then hatch into larvae.
Common symptoms of mouth larva
Mouth larva presents several distinctive symptoms, which include:
- Severe pain: Intense pain in the affected area due to tissue damage and inflammation.
- Swelling: Noticeable swelling in and around the mouth.
- Bad breath: Foul odor resulting from decaying tissue and larvae activity.
- Ulceration: Presence of ulcers and sores in the mouth.
- Bleeding: Occasional bleeding from the affected sites.
- Movement sensation: Sensation of movement within the oral cavity due to larval activity.
- Foul odor: Infected areas may emit a strong, unpleasant smell due to tissue decay.
- Lesions: Painful sores may form in the mouth where larvae have burrowed.
- Necrotic gums: Gums may become dead or decayed, leading to blackened tissue.
- Pulsating extraction wounds: The sensation of throbbing or movement in infected oral wounds.
- Oozing lesions: Lesions may release pus or other fluids as a result of infection.
- Destruction of oral tissues: Larvae can cause severe damage, eroding healthy oral tissues.
