As long as you don't have any other symptoms like pain or mobility of the tooth,and if the fracture line does not expose the nerve, the broken part can be built up using tooth coloured material ,and made to  look like your natural tooth again. Please visit a dentist for details.

There are tooth colored filling material available especially composites. You can get that tooth repaired by a filling. Another option is a crown, in which your tooth is trimmed off and made small and a crown is placed over it. Your bite plays an important role in the filling. So please get a check up done and get the best option for it. Hope this helps.
