how long does it take for numb tongue to heal?

Dentist gave me a shot in the trunk area where jaw comes together, he hit the nerve in my tongue. It felt like a lightning jolt. I have been numb for a week now. My tongue is starting to tingle more and have pain in front tip. Does this mean its healing? I know I am in Gods hands, and the is mending my nerves, just wanted to know if there are any herbs to help me ASAP. Mother to 5. Thank you.

Mine is numb too for one week. Yesterday i tried cutting a bird chilli, rubbing it on my tongue and now my tongue is lighter. I did it 5 times in total throughout whole day. My tongue felt lighter thanever. Today i woke up and can feel more sensations coming back. It feels like a miracle you can try. Hope it works.
