I bit the inside of my cheek a few days ago. How can I make it better faster?

A few days ago I bit the inside of my cheek unusually hard. It was bumpy and I punctured it. I’ve been trying to keep it clean and have done mouth rinses with warm salt water. I also use my old cure of listerine but that isn’t making it heal any faster like it usually does. It isn’t getting worse but I don’t think it is getting better.
I’ve never had a bite take this long to recover but then I don’t think I ever bit myself this hard.
I would appreciate any home remedies to help heal it quicker.
