You need to talk to your dentist/periodontist to make sure that healing is progressing normally. Front upper teeth require more time to heal and it might require 6 months before you can get final crowns depending upon crown lengthening. Best of luck.
Generally Root canal treated teeth need crown to protect from fracture as teeth become brittle after RCT.
Kindly consult dentist with your dentist for options. Implant option is great option but your dentist needs to evaluate for amount of bone you have. Xray or CT scan will help in determine the treatment options.
You can see your dentist and there are various options from composite repair(bonding) to veneers.
Consult your dentist and he/she can tell you about options for saving or not saving with risks and benefits. Build up and crown will be one option if enough tooth structure is remaining or crown legthening might be needed if fracture is below gum line or close to your tooth bone . You have to consider longterm and short term prognosis in making decision. Best of luck.
