In Sleep Dentistry (Sedation Dentistry) you are sedated just enough to be unaware of the treatment, as if you were asleep. You will wake up with little or no memory of your time in the dental chair. This is very popular with patients that are apprehensive of dental treatments, those with strong gag reflex and for those with major dental work or surgery. Lancaster Dental offers oral sedation, IV sedation and nitrous oxide (laughing gas). These sedation methods are used with local anesthetic. Please sign up for a free sedation consultation with our dentist to determine which is best for you.
