3 days ago i had my lower horizontal wisdom tooth extraction since now my half tongue is feels numb and swollen i hv feeling of trickling on tongue

See your dentist: extraction of wisdom teeth could be traumatic and some time required cutting and suturing. so the edema and swelling is expected. but the numbness to last three days is unusual. so my advise in addition to gargling with salt and water, and apply ice as much as you can, talk to your dentist and check if this is expected or not.

Call your surgeon: Please call your surgeon for a post extraction follow up appointment. Although these complications are common and usually resolve on their own, it is important that the surgeon be advised of the situation. All the best....

Contact oral surgeon: See your oral surgeon to make sure the nerve damage is transient. You may need to be referred to a microsurgeon for further evaluation.

Transient Numbness: It could last for a few hours, day, or even months. call your oral surgeon for further instructions and treatment.
