Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain there has been chemical burning of the tongue caused by the chemicals present in the phenol leading to atrophic changes in the papilla that contains
taste buds leading to loss of taste sensation..
You should consult an Oral Physician and get evaluated that whether the burns are first or second degree and get treated accordingly..
As of now you can suck on ice pops,and do gargles a numbing mouthwash for relief from burning and pain..
Use alcohol free mouthwash for gargles to prevent infection..
Take
multivitamin tablet one daily for 15 days..
Avoid hot, spicy and citrus foods..
Hope this information helps..
