If the teeth are just chipped a little composute filling should be enough. If the break is bigger you might need root canal treatment and crowns.

this really depends on the extent to which your tooth has chipped/fractured. enamel/dentin or reached the pulp. based upon the relevan radiographic(x-ray) evaluation. the chipped part would be recreated with dental composite restorations or root canal treated and crowned . if severely chipped then extracted and replaced with an implant. hope this answers your question.
