How much compensation can I claim for losing a tooth in an unprovoked assault?

[Usman]

I was assaulted in the street the other day, I was attacked by a man with a gang and suffered multiple injuries, black eye, broke nose, cuts and bruises and I also lost a tooth. The police have been informed and they are still investigating the assault, Can I claim compensation for criminal injuries? How much compensation could I be entitled to for getting a tooth knocked out?
