If the implant area is made numb/anesthetized before the implant placement, it is not possible to feel any sensation of pain, even most people do not even notice when the implant is placed.
Making the implant area numb is a very routine procedure for the dentist. Methodologically, there is no difference between the local anesthesia of the implant area than that of the tooth extraction or a filling. In all of them, including the implant, similar local anesthesia and other anesthetization techniques are used.
During the implant procedure, patients feel no pain either
