Green Cheek Conure's beek problem?

My green cheek conure's beek seems to be split in two parts at the tip. The lower part is extremely sharp almost like a needle. Is something wrong with his beek? When I recently looked at other green cheeks, they didn't have this problem? what should I do?|||You have to take him to the vet to get his beak trimmed. There is lots of reasons for overgrown beaks, but your vet will decide what that reason is. Doe he have a proper diet? Toys to chew on? Make sure he gets it trimmed, its prob very painful to him
