Cloves can be taken for gum diseases like gingivitis and periodontitis. Cloves significantly controlled the growth of oral pathogens, which are responsible for various oral diseases. Cloves can also be used for toothaches due to their pain-killing properties.
Onions are often used to prevent tooth decay and oral infections. Chewing raw onions for 2 to 3 minutes can potentially kill all the germs present in the oral area and surrounding places like the throat and lips.
