Saliva does more than keep our mouth wet
Saliva has several important and essential roles in your health:
- saliva helps digesting food
- saliva protects teeth from decay
- Saliva lubricates the mouth and allows free movement of the jaws and tongue
- saliva prevents infection by controlling bacteria and fungi in the mouth
- saliva makes it possible for you to chew and swallow
- saliva prevents bad breath
How does saliva keep us healthy?
Saliva acts in the mouth like oil does in an engine. Tongue and lips movements are not smooth without enough saliva. Thus one finds it hard to speak and chew food, especially dry and hard food. Worse than that, one may not get the needed nutrients if chewing and swallowing certain foods are hampered. In addition, tooth decay or other infections in the mouth can develop.
