Hi..
Welcome to HEALTHCARE MAGIC..
As per your query symptoms of having cottony wool mouth along with
dry mouth and dry throat is indicative of
Fungal infection in mouth known as
Oral thrush and dry mouth and throat can be due to it..
At times it also goes opposite and dry mouth can be a cause for thrush..
Do not worry, consult an Oral Physician and get evaluated and if thrush is diagnosed as the cause the physician can advise you to take anti-fungal mouthwashes like Nystatin mouthwash,
clotrimazole lozenges and taking more of probiotics like Yoghurt and garlic.
If still there is no improvement in 15 days oral anti-fungal medicines like
Fluconazole oral can be advised.
For dry mouth chew sugar free chewing gums as it stimulates saliva flow.
Saliva substitutes like "Artificial saliva" containing methyl cellulose can be instilled multiple times in mouth for lubrication.
Avoid anti-microbial mouthwashes and gargle using mouthwash specially formulated for dry mouth..
Drink plenty of water..
Hope this information helps..
Thanks and regards..
