What to do if a 4 year old girl fell on her face and is bleeding from her gum?

My 4 year old niece fell hard on the ground and hit her face. When she got up she was bleeding from her gum right over her 2 upper front teeth. She keeps saying her teeth are hurting but I'm not sure if she really means teeth or she just doesn't know the difference between teeth and gum but either way should this be something to worry about? Her teeth seem normal though, just some tumering from the fall.

What should be done in such case before considering taking her to a doctor/dentist?
