What can i do for a Non-vital front tooth that is not painful or infected?

Thank you for your question.  First and foremost, if a tooth is determined "non-vital" there should be diagnostic information on hand to back up the diagnosis.  Ensure, you have been properly educated with your dental team on what the etiology is that has caused your tooth to be non-vital.  Assess your radiographs and clinical exam info together with your dentist to better understand if you have an infection, dental caries and/or possibly trauma to the tooth for the vitality status (if "dead or alive").Moreover, if the tooth is indeed determined non-vital, then a root canal is typically the recommended course of treatment to properly seal and preserve the tooth prior to any cosmetic whitening.  Intrinsic bleaching within the root canal is a technique your dentist and/or endodontist can possibly assist with following endodontics.  In addition, certain situations of bonding on the facial (or crown) of the tooth can be successful following whitening to determine the proper shade as well as possible porcelain veneer / crown restorations for your desired shade and result.At the very least, consult with your dentist again regarding your dental treatment to ensure you are well informed about the whitening and status of the tooth prior to your "big day" in September!!

NOTHING CAN REVIVE DEAD NERVE.  so do not waste time for that. first u start with RCT and intrinsic whitening, and not get desired result , go for veneer on that tooth
