What Exactly Is Sedation Dentistry?

Sedation dentistry is the range of techniques that dentists employ to help patients relax and reduce their anxiousness while conducting dental procedures. Most people think that you will be unconscious while on sedatives.

Instead, most sedatives keep you awake and conscious except for general anesthesia. Sedation is not only anesthetics but includes the application of a variety of sedatives that helps you relax and feel comfortable.

The levels of sedation are of four categories –

  • Mild sedation – Mild sedation will keep you awake and conscious, and you will barely notice any difference from being normal. You will only feel a relaxing effect for the duration of the sedation.
  • Moderate Sedation – This form of sedation will keep you awake through the entire procedure, and you will be able to follow instructions from your dentist. However, you apparently will not be able to remember the details of the process afterward.
  • Deep Sedation – This type of sedation is the highest type without using general anesthesia. You will be at the brink of consciousness in profound sedation, but the dentist can still wake you up or make you follow their instructions if there is a requirement.
  • General Anesthesia – Administering general anesthesia will make you slip into unconsciousness completely. You will not be able to wake up while under the effect of general anesthesia. An anesthesia technician is mandatory for administering general anesthesia and for regularly checking on your vital signs while you are unconscious.
