Hi,
1. Crown .. more natural would be metal free that is Zirconium... have most natural looking and long lasting with proper maintainance ( nowadays you are getting warranty (10 to 15 years) for the crown itself.. you can opt for those) .
2. Tooth ... But before you go ahead with crowning ... I advice you to evaluate the tooth itself ,... usually when there is trauma... tooth may become non-vital over a period of time.( months to years) ,so yoh may have to get an X-ray and vitality test to conclude that.
If tooth is non-vital ,you have to go for root canal treatment (RCT) and CROWN , IF its vital... then no need for RCT.... go ahead with direct Crown.
Next Steps
visit dentist for evaluatio. and treatment
