Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain it seems that you are suffering from
Dry mouth or
Xerostomia and can occur due to a number of causes like oral infections like Thrush,
salivary gland disorders,
nerve damage, surgical removal of salivary glands,
diabetes, hormonal imbalances, side effect of medicines etc..
The burnt feeling is also due to dry mouth..
I would suggest you to consult an Oral Physician and get evaluated and a thorough clinical evaluation can help in confirming the diagnosis and treatment of the underlying cause can help in resolution of symptoms..
As of now you can take supportive treatment like chewing sugarfree chewing gums to increase saliva flow, drink plenty of water..
You can also take saliva substitutes like "Artificial Saliva" and it can be instilled multiple times in mouth for lubrication..
Hope this information helps..
Thanks and regards.
