<s>[INST] Hi I had all four of my wisdom teeth removed 3 weeks ago. the left part of my tongue and the floor of my mouth on the same side are somewhat numb. I d not have pain but my taste is severely altered. I believe this is caused by damage to my lingual nerve which I was told could be a risk before the surgery and also told that is 85% of the cases is temporary and will go away within a few weeks. How can I tell if this is something that will gradually improve and go away or is more of a permanent nature [/INST] Hello,Thanks for consulting HCMRead your query as you have altered taste sensation after wisdom tooth extraction yes this can be due to lingual nerve injury during surgery or it can be due to depapillation of papillae also . I will suggest you to take Take Neurobion tablet by consulting with your local doctor . Do warm saline rinses two - three times a day. Hope this will help you. </s>
