Hello, As per your complaint, it looks like dry mouth can be due to causes like: -Severe dehydration, -Side effects of medications if you take any. -Salivary gland dysfunction. -Nerve damage supplying salivary glands. -Oral infections like thrush. -Sjogren s Syndrome etcetera Altered taste is due to reduced saliva flow only as the saliva maintains taste buds and in the absence of appropriate quantities of saliva, there is alteration in the function of taste buds leading to altered taste. -For dry mouth chew sugarfree chewing gums. -Drink plenty of water. -Avoid regular mouthwash and use a specialized mouthwash that is formulated for dry mouth patients like Biotene. -You can also instill artificial saliva drops. -Suck tart candies as it also stimulates saliva flow. It does not improve, consult an oral physician and get evaluated. Hope I have answered your query. Let me know if I can assist you further. Regards, Dr. Honey Arora
