Yes it can definitely be due to
vitamin deficiency but nothing can be said for sure without a proper clinical evaluation of the case. You can start taking multivitamins on a daily basis and hope for the symptoms to resolve. If they don't, it would be prudent to visit an oral pathologist for a proper clinical evaluation.
Cleaning of your tongue with your toothbrush after every time you brush your teeth is also recommended and at the same time it is recommended not to use tongue cleaners for this purpose.
