The best option for you is to have an implant done and get the tooth replaced. It requires surgical placement of implant followed by placement of crown of the missing tooth and would require about 6 months to complete the procedure. Alternatively, you can get a bridge made wherein the adjoining teeth of the missing tooth are prepared to receive the crowns. This can be instantly done but requires the adjacent tooth to be reduced. Well, what would be most suitable for you also depends on a clinical examination.
