When I had my wisdom teeth removed, I had a bad sore throat from the breathing tube that they put in.

My mom made me a honey and lemon drink which I found to be quite soothing even though you would think lemon would make it sting!

Sore and tender throats from the tube can last about a couple of days. Mine may have lasted slightly longer but no more than 3 days. I think it depends on who does it because some can be rough which could scratch the throat in the process.

I am not sure about the part where you cannot talk now though. Do you mean that your throat is so sore you cannot talk? If it persists I would perhaps recommend that you speak to someone like your doctor/GP as they may be able to help you.

Good to hear that your surgery went well.
