Woman after Nitrous Oxide Comfort Dentistry in Puyallup WA

At Smith & Wetterhus Dentistry, your comfort is our primary concern. One of our most commonly used dental sedation methods is nitrous oxide, or laughing gas. You might not be giggling before it’s used, but chances are you won’t feel — or fret — much after you breathe this gas.

Nitrous oxide is perhaps the most sought-after clinical sedative because it offers an ideal experience: a painkiller that induces a euphoric feeling. It is a safe and effective sedative that is mixed with oxygen and inhaled through a mask that fits over your nose. It is odorless, pleasant tasting, and typically begins to work within five minutes.

When laughing gas is first administered, you’ll feel:

  • Relaxed
  • A warm sense of well-being
  • Happy or silly
  • A tingling sensation
  • Numbness in your mouth, hands, or feet
  • Hearing changes
  • Sleepiness
The effects of nitrous oxide wear off a few minutes after the gas supply is stopped, so if you opt for this sedation method, you should be able to drive home after the procedure.

Laughing gas may not be appropriate for you if you:

  • Are pregnant
  • Have a stuffy nose
  • Have chronic obstructive pulmonary disease
  • Suffer from congestive heart failure
  • Have a recent head injury
  • Have an ear infection
  • Are taking medicine for a psychiatric condition


Is nitrous oxide conscious sedation?
Yes, nitrous oxide is a form of conscious sedation. You will be fully awake and alert during treatment, but your feelings of fear and anxiety will be alleviated.
Will my appointment be painless with nitrous oxide?
Laughing gas alleviates the discomfort and anxiety associated with some treatments. Prior to your treatment, Dr. Daniel S. Smith, DDS and Dr. Gregory J. Wetterhus, DDS will discuss which pain management and sedation options are best for you.
Is nitrous oxide safe?
Nitrous oxide is considered extremely safe. Side effects occur rarely and include dizziness, nausea, and headaches.
