Dental Tips to Prevent Black Fungus


Black fungus infection has emerged as a threat to patients who have recently defeated COVID-19 infection.

Many states in India have already declared black fungus infection as an epidemic. The seriousness is due to the speed at which the infection can spread and become fatal even before anyone can realize it. Hence, it is absolutely necessary to identify the disease as early as possible so that it can be treated.

Which Fungi Causes Black Fungus Disease?

Mucormycetes fungi cause black fungus, which belongs to the class of Zygomycetes. It is commonly found in soil, filthy tanks, organic matter, and animal feces, and it cannot spread from man to man or from an animal to man.

How Does This Fungal Infection Spread?

The fungal infection most commonly follows a particular path of infection from beginning to end. The infection frequently starts from the mouth, spreads through the sinus to the nose and throat. Then it takes the path towards the eye and then finally perforates the skull bone to enter the brain. The total time taken for the spread from the mouth to the brain may be less than a week. Therefore, the early identification of the infection becomes extremely important.

What Are the Dental Tips to Be Followed to Prevent Black Fungus?

Since the disease starts in the mouth, it is obvious that taking utmost care of the mouth becomes a thing of paramount importance.

1. Maintain Oral Hygiene:

The importance of maintaining perfect oral hygiene cannot be overemphasized. Brushing twice daily and use of an antiseptic mouthwash is also a must. Flossing and the use of interdental brushes can also help prevent the accumulation of dental plaque. Limiting sugary or starchy foods will also prevent the fall of pH in the oral cavity. Drink a lot of water instead of sugar-containing juices. Frequent rinsing after every meal also helps to prevent plaque formation.

2. Avoid Dental Treatments Immediately After COVID 19 Recovery:

Any invasive dental treatment like extractions, surgeries have to be avoided immediately after recovering from COVID-19. Since the immunity has been compromised, any small insult to the oral cavity can become a starting point of infection. The healing capacity of the individual is also compromised, and hence it may take longer than usual to heal, predisposing the wound to infection. It is safe to wait at least 25 to 30 days after recovery before undergoing invasive dental procedures.

3. Changing the Toothbrush and Tongue Cleaners:

After recovering from COVID-19, it is mandatory to change the used toothbrush and tongue cleaners as they may contain germs from the previous infection. Keeping them separate from that of the other family members will also help.

4. Frequent Mouth Rinsing:

It is advised to rinse the mouth after every meal and use an antiseptic mouthwash as prescribed by the dentist. Chlorhexidine and Betadine mouthwashes are effective in containing oral infections.

5. Drink Filtered Water:

Since the fungus can be present in dirty water tanks and pipelines, it is advisable to drink filtered water. Drinking unclean water can cause the fungus to enter the body through any cuts or ulcers in the mouth.

6. Change Masks Frequently:

It is advisable to wash the cloth mask and air dry it in direct sunlight after every use. In the case of a disposable mask, it should be discarded after every use.

Is There a Vaccine for This Disease?

Still, there is no vaccine available to prevent the spread of the disease, and this particular black fungus disease cannot be diagnosed in any of the blood tests, unlike any fungal infection.

How to Prevent Getting the Infection?

The disease can be prevented by following the below instructions, they are,

a) Avoid contact with filthy areas.

b) Do not stay in a water-damaged building.

c) Avoid close contact with,

d) Wear shoes, gloves while doing gardening and agricultural activities.

The key is identifying the problem early and reporting it as soon as the symptoms appear. This gives the physician a chance to control the disease and prevent a fatality. As the mouth is the primary area of infection, keeping up thorough care for the same becomes supremely important.
