Inhalation Sedation at Nova Smiles Dental

Woman wearing inhalation maskDr Jenny Hong (Dentist) has a special place in her heart for our patients that feel anxious about going to the dentist. We have a passion for facilitating gentle care to individuals who have experienced uncomfortable dental care in the past or require treatments that they’re too afraid of getting.

For your convenience, one of the methods we use is relative analgesia — more commonly known as “happy gas” (nitrous oxide) — to help you relax during your appointment.

How Does Inhalation Sedation Work?

Relative analgesia is a safe and gentle anti-anxiety sedative that eases our patients as they remain fully conscious throughout their procedure. Nitrous gas is mixed with pure oxygen and breathed in through the nose, creating a relaxing effect throughout the entire body. The fast onset allows for an efficient appointment, with the gas quickly wearing off within just a few minutes of being turned off. Adults will even be able to drive themselves home afterwards.

Happy gas can be used for nearly any dental procedure and is safe for all ages.

Advantages of Requesting Happy Gas

  • Feel more relaxed throughout your dental appointment
  • No lingering side effects
  • Appropriate for all ages (including children)
  • Only takes a few minutes to start working
  • Completely reversible within a short window of time

Great for Any Appointment

From a routine scale and clean to treating a dental emergency, nitrous oxide is a convenient and safe way to ease your mind when a deeper type of IV or oral sedation isn’t necessary. Although you will feel more relaxed, we will still use local anaesthetic as necessary to numb the tooth being treated and prevent unnecessary discomfort.
