Sinuses are small cavities around our nose that help in many ways to our nasal cavity, but we are not going to discuss their functions!
Sinusitis is the inflammation of sinuses that can be acute or chronic.

Our tonsil has folds and crevices that can lodge and trap food particles, saliva, mucus, and dead cells on their way out.

These traped things can cause a bad smell from the mouth and nose when infected by bacteria.
Poor oral hygiene and large tonsils are the main causes of tonsil stones. Gargling and good oral hygiene can help remove those tonsil stones.

5. Phantosmia
