  • Visit your dentist regularly as it will help to detect any dental problem easily as well as black fungus symptoms can be detected at an early stage.
  • Toothbrushing- Brushing twice a day for 2 minutes is recommended for maintaining proper oral hygiene
  • Flossing & Interdental brushing-It can keep clean tooth and healthy gums.They both effectively removes food particles in between the two teeth.
  • Oral Rinsing- It reduces the microbial load and helps to reduce infection through saliva.It can be done by Chlorhexidine mouthwash


  • Disinfecting toothbrush and tongue cleaner-Keep separate oral hygiene kit for each family member as it will prevent infection spreading from 1 person to another.


  • Discard toothbrush and tongue cleaner after Covid infection- Mouth is the home for microorganisms and toothbrush carries the virus and other microorganisms present in the mouth so it is better to discard toothbrush after Covid infection.









  • Regularly monitor blood glucose after Covid in diabetic patients


  • Maintain oral hygiene and overall hygiene


  • Don’t stop wearing masks even after recovery from Covid


  • Wear clean mask everyday- A mask can harbour microorganisms and can cause black fungus .So wear a clean surgical mask everyday.
