In case of cracked and decayed molar, the line of treatment depends on the location of crack line. If the crack line is horizontal and is present on the tooth, then the tooth can be saved by root canal therapy and capping but if there is vertical crack line present, it is always better to extract the tooth. You can get the tooth extracted now and get it replaced with implants. If you don’t have much of money for implants, you can even opt for fixed bridge. It is better to get the tooth pulled out now as later it may cause some complication.
