If you are undergoing root canal treatment, then your dentist will inject a local anesthetic into your mouth. If you have anxiety about a procedure, then your dentist can offer nitrous oxide as a relaxant. Learn a little more about the anesthesia and sedation methods used in dentistry below.


Here are a few of the anesthetics your dentist may use on your mouth:

  • Local Anesthesia: This is used to numb an area of the mouth that will undergo a dental procedure.
  • Topical Anesthesia: Often this is used to numb oral tissue before an anesthetic is injected into the area. It can also be used to numb sores in the mouth.
  • Non-Narcotic Analgesic: This painkiller medication (which can be ibuprofen, aspirin, etc.) may be offered after procedures.
  • Narcotic Analgesic: This medication affects the central nervous system and is used after more extensive dental procedures.


You don’t need to fear dentistry, ask your dentist about some of the sedation methods available such as:

  • Nitrous Oxide: “Laughing gas” has been used in dentistry for over 150 years. Breathing in nitrous oxide through a nose mask helps patients relax while allowing them to stay awake.
  • Oral Sedation: Taking an oral sedative lets patients relax and stay awake just like nitrous oxide does.
