Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain yellowish discolouration of the tongue is most probably due to poor maintenance of
oral hygiene that leads to accumulation of food debris, dead cells and also bacteria and fungus over the tongue..
If you have infected tonsils infection can also be a cause...
I would suggest you to consult an Oral Physician and get evaluated and a thorough clinical evaluation is generally sufficient for diagnosis..
You can be advised to clean your tongue daily using a tongue scraper..
You can gargle with 1:1 solution of
hydrogen peroxide and water..
You can dip a soft toothbrush in the above solution and brush your tongue gently..
Eat more of hard foods like apples, carrots etc as it cleans the tongue by frictional action..
You should drink plenty of water..
Hope this information helps..
Thanks and regards.
