I just dropped my airbrush on a hard concrete floor, but luckily I think I only managed to bend one of the crown bits on my 'crown tip'. Does anyone know if it is worth getting a replacement tip, and will it affect my airbrush performance?
Any help would be appreciated.

Depends on what type of airbrush you got. For a cheap on it will probably be wise to buy a new one. Expensive ones usually have a wide range of spare parts. Ask your LHS.

Cheers

PS. A "broken" airbrush ia allways a good reason to buy a new one :-) :-) :-) :-) :-)

Its an iwata HP-C Plus

Iwata is a well known brand, and it will be an easy task to change the nossle tip. It will not affect the performance of your airbrush. Just remember to get the correct type.
