Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain yes, it is true that
Zinc Deficiency can cause
altered taste in mouth and in case if there is suspected cause of Zinc deficiency a
Blood test can be carried out under supervision of an Oral Physician so that the cause can be ruled out..
Other common causes of altered taste can be Vitamin B 12 deficiency, teeth and
gum infection, dry mouth, oral infections,
post nasal drip, head injuries, nerve related problems etc..
Get a thorough clinical examination done and treatment can be done according to the cause diagnosed..
As of now you can chew flavoured sugar free chewing gums..
Gargle with flavoured antiseptic mouthwash..
Drink plenty of water..
In case if zinc deficiency is confirmed you will be advised Zinc Supplements..
Hope this information helps..
Thanks and regards.
