Yes. Dental implants can really be performed in one day by taking out the tooth, insert a dental implant and attach a new tooth immediately. Also, it is possible to take out a whole bunch of diseased teeth, insert four to six dental implants and attach a whole set of brand-new teeth to them on the same day, but everything has to be done under certain conditions. It requires the right anatomy, the right set of implants, and the right conditions in the patients.
