The work would be much more difficult without this procedure. Usually, we use anaesthetics in order to minimise the pain when injecting in the tooth’s surface. The doctors may use a local anaesthetic to get benumbed an area in order to prepare it for administering a local injection anaesthetic.
At the same time, the dentists may use these medications, in order to induce conscious sedation, when the patient relaxes during the treatment, but may answer back when talking to him or touched. The sedatives may be administered before, during or after the dental procedures.
