An impression is taken and a temporary crown is placed over the top of the prepared tooth. The impression is sent to the laboratory and the crown is then fabricated. The next appointment usually between 2-3 weeks later involves cementing the permanent crown in place. If all goes well, this appointment takes 30 minutes.
Very few procedures in dentistry will last a lifetime. The average crown or bridge should last about 5-7 years. A well done crown or bridge can last longer than 10 years provided that the person has good oral hygiene and comes to the dentist at least twice a year for examinations, cleaning, and follow-up care.
