Definitely a good idea to check with the dentist. They need to make sure the nerve hasn't been damaged, and the tooth is in good shape.
My 3 year old had a fall and a minor chip, and all the same symptoms with food eating and drinking bothering him. The dentist saw the tooth/root was fine, and after a few weeks sensitivities to food stopped. Just baby the tooth for a while and eat room temp foods, and show them how to eat on the other side of their mouth.
If the chip is extensive, obviously the dentist will know how to tend to that as well.
