Hi.. Welcome to HEALTHCARE MAGIC.. I have gone through your query and can understand.. As per your complain dry mouth and throat can occur due to a number of reasons like salivary gland disorders, nerve damage supplying the salivary glands, oral infections like thrush, mouth breathing, side effect of any medication [if you are taking any] etc.. You should consult an Oral Physician and get evaluated and a thorough clinical evaluation can help in diagnosis and treatment of underlying cause can help in relieving the dryness. As of now you can suck tart candies and chew sugar free chewing gums as it will help in stimulating saliva flow.. Drink plenty of water.. Gargle with specialized mouthwash formulated for dry mouth like Biotene mouthwash or other brands.. Avoid using regular mouthwashes as they have drying effect over mucosas.. Hope this information helps.. Thanks and regards. Dr.Honey Nandwani Arora.
