Dental implants are inserted into the jaw bone under local anaesthetic so the procedure is not painful.
Just like with any other dental procedure, local anaesthetic takes away any painful sensation for a number of hours so that you can comfortably undergo the procedure without the risks that are carried by the use of general anaesthetics (where you are not conscious).
Following the procedure, it is normal to experience some discomfort for 2-3 days after which symptoms should begin to resolve. In this time, you should carefully follow postoperative instructions to ensure quick and uneventful healing.
Over-the-counter painkillers (analgesics) are often recommended and are sufficient to get you through this period comfortably. After a few days, and from thereon in, you will feel no sensation from your implant.
