• Local anesthesia reduces or eliminates pain in the area where it’s applied. It can be applied as an injection or topical applied directly to the skin. The anesthetic numbs the area where the dentist needs to do a procedure, such as extracting a tooth or filling a cavity. Anesthesia usually takes effect within a few minutes and lasts for an hour or two. If your anxiety stems from a fear of pain, this is one of the easiest ways that dentists can manage the issue.
• Sedation can be used when you need something more than local anesthesia to help you relax and control pain during a complex procedure, such as an oral surgery, or if you’re especially anxious. Sedatives can be injected or inhaled and will put you in a light sleep.
