Hello and Welcome to Healthcaremagic. I will try to the best of my ability to help you with your concern. The symptoms in mention in query are occurring due to condition called dry mouth . There can be many reasons for dry mouth like diabetes , fever due to infection, dehydration and less production of saliva. I would suggest you to consult oral pathologist or dentist for proper diagnosis . Doctor will take medical history , may order test to check composition of saliva or blood test for any underlying disease or infection. If there is any dental infection ( gingivitis) doctor will treat accordingly (scaling and curetage ) and prescribe antibiotics. Doctor may prescribe drug like pilocarpine in case production of saliva is less or refer to other specialist if there is underlying condition other then dental problem. Till the drink as much water as you can , suck on sugar free candy and avoid food that promote dehydration like sugary and fatty food . Also do betadine rinses and maintain proper oral hygiene . I hope it helps. Thanks Dr Harry Maheshwari
