What can I expect at my dental visit? Each visit can vary in time due the amount of procedures being completed and the extent of the treatment. Cleanings generally take an hour to complete; time may be extended if a more extensive cleaning is required. Crown preparations can take 1-1 ½ hours for your visit. Bridge preparations can be completed in 1-1 ½ hours. Cavities are filled anywhere from 30 minutes or more, depending on the number of fillings being completed at your visit. Implants vary in time from 45 minutes to an hour, per implant being placed. Completed treatment is same day to months in duration. A dental assistant will be able to answer any questions you may have.
