Our expert says:
This may be a very rare side-effect of the surgery, possibly on the basis of stretching of the lingual nerve during the surgery. This happens because the mouth is opened with a special instrument during surgery. The nerve runs in the tongue and helps with taste. It is not permanent, but the recovery period may vary from person to person. It could take from 6 weeks to three months for taste to normalise. It could also be due to the medication you were taking. It may be of value to take a Zinc supplement to help with the healing process. Check with your surgeon.
