Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain it seems that the burning and scalding feeling over the tongue and tingling along with having a dry mouth and dry throat is pointing towards a condition known as
Burning Mouth Syndrome and it is occurring secondary to dry mouth..
Bad breath also occurs due to same cause..
I would suggest you to consult an Oral Physician and get evaluated and a thorough clinical evaluation and investigations to rule out the underlying cause of dry mouth like
salivary gland disorders,
nerve damage oral thrush, hormonal imbalances, side effects of medicines can help in proper treatment and relieving the symptoms..
As of now you can gargle with a numbing mouthwash containing Lignocaine to relieve pain..
You can gargle with specialized mothwash for dry mouth patients like Biotene..
You can chew flavoured sugarfree chewing gums.
You should instil artificial saliva drops in mouth..
You should brush twice a day and not more as it further has drying effect in mouth along with regular mouthwashes..
Avid spicy foods and take a soft diet..
Suck ice and do cool water rinses..
Hope this information helps..
Thanks and regards.
