Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain it seems that gums turning white along with ulcers on tongue and gum and throat pain can be due to causes like viral infection while can also be due to Apthous Somatitis causing apthous ulcers..
Pain in ear and throat can be secondary to
throat infection..
It does not seems to be probably cancerous..
I would suggest you to consult an Oral Surgeon and get evaluated and a thorough clinical evaluation and investigations like Oral Swab culture,
blood test and if needed a
biopsy from the ulcers can be done to rule out the cause and treatment can be done accordingly..
As of now completely quit
smoking and also do numbing mouthwash gargles like Lignocaine to relieve pain..
You can also suck ice and drink plenty of water..
Take Vitamin B complex supplements and also take
Ibuprofen to relieve pain in ulcers..
Hope this information helps..
Thanks and regards.
