Nitrous Oxide (or laughing gas) is a sweet-smelling, non-irritating, colorless gas which you can breathe. It has been the primary means of sedation in dentistry for many years. Nitrous oxide is safe, the patient receives 50-70% oxygen with no less than 30% Nitrous oxide.
The patient is able to breathe on their own and remain in control of all bodily functions.
The patient may experience mild amnesia and may fall asleep, not remembering all of what happened during their appointment.
There are many advantages to using Nitrous Oxide:
- The depth of sedation can be altered at any time to increase or decrease sedation.
- There is no after effect such as a “hangover”.
- Inhalation sedation is safe with no side effects on your heart and lungs, etc.
- Inhalation sedation is very effective in minimizing gagging.
- It works rapidly as it reaches the brain within 20 seconds. In as little as 2-3 minutes its relaxation and pain killing properties develop.
Conscious sedation is an oral medication that is prescribed and taken one hour prior to your dental appointment. Most of our patients sleep right through their dental procedures and don’t remember much about that day, but every patient reacts differently. Typically this sedation is used for oral surgery and lengthy dental procedures, but can be used if you are highly anxious and need help relaxing.
Reasons to not use Nitrous Oxide or Sedation:
You should not utilize Nitrous Oxide if you have been diagnosed with chronic obstructive pulmonary disease (COPD). Though there are no other major contraindications to using nitrous oxide, you may not want to use it if you have emphysema, exotic chest problems, M.S., a cold or other difficulties with breathing.
