My kids go to pedia dentist: HOMER SEDIGHI, DMD. /www.kidsdentistry.com off Olive Blvd/east of hwy 40 area.
His office is very kid friendly-the decor, the prizes, the toothpaste flavors etc! My kids like to go there.
per his emerg.list on website: if tooth is broke/chipped: rinse w/clean cool water. Apply direct pressure to the bleeding area w/a clean cloth. If swelling is present appply cold compress (i guess suck on ice or pop cycle?) and then call denist asap.
Good luck. Motrin might help w/the pain & possible infection.
