Milk does not help heal wounds. If you have bitten your tongue, it will heal on it's own; no need to do anything.
I dont think they heal at all, because the tongue is a muscle.
yes
Depending on the severity of the bite it can take anywhere from a 2 or 3 days to a little over a week. I speak from personal experience. The only thing to do is use some peroxide to keep it clean and use some warm salt water to help the healing. It might be hard to eat and or feel weird while talking.
Yes it will heal.
You must find out if you missed a few doses of your medicene.
Fruit by the foot!

You can get a cut on the tongue if you eat foods that is highly made of fiber like sugar. You make it heal faster by eating lots of fruits and vegetables.
drinking and drugs
Only thing you can do is give it time to heal.
I have my Tongue pierced too. I noticed the same cut, Was it self done? I have heard your tongue is the fastest healing part of your body so if you take out the jewelry it should heal right up.
Just give them time and they will eventually heal. give it a week at most
