Question:

Can chewing gum on a regular basis improve the singing voice? And if so, could you suggest any types?

Answer:

The only benefit of chewing gum is that it can keep you producing saliva and therefore keep the voice “moist.” I think it would be better to just drink water or Throat Coat Tea. If you are going to chew gum or suck on hard candies, avoid strong mint or lozenges with eucalyptus — these tend to dry the tissues and are really meant to aid decongestion. Better to steam if you are stuffed up.
