Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain the symptoms of severe dryness inside mouth along with tongue or lips sticking to teeth is happening due to dryness in mouth that is also known a
XEROSTOMIA..
It can occur due to a number of causes, however common causes can be
severe dehydration,
salivary gland dysfunction,
nerve damage supplying salivary glands, oral infections like thrush, sjogren's syndrome..etc..
You should consult an Oral Physician and get evaluated and a thorough clinical evaluation and investigations as per suspected cause has to be done, as the treatment of underlying cause will help in resolving the
dry mouth..
As of now for dry mouth chew sugarfree chewing gums,suck tart candies, drink plenty of water, avoid regular mouthwash and use specialized mouthwash that are formulated for dry mouth patients like Biotene, you can also instil artificial saliva drops..
Hope this information helps..
Thanks and regards.
