X-rays are a valuable tool when the dentist is designing any kind of dental restoration like a crown or implant because certain aspect of the mouth can be taken into consideration when designing the restoration. They are also highly beneficial in detecting cysts, abscesses, and tumors that could not be seen otherwise. They can also be used to identify impacted teeth that are not erupting properly, and in this event, the proper action can be taken to eliminate any discomfort the impacted tooth is causing.
