Nitrous Oxide sedation (Laughing gas)
This is where the patient wears a nose mask and breathes in a mixture of Nitrous Oxide and Oxygen. At all times they can adjust their intake of gas if they breathe through their mouth they reduce the amount of gas breathed and so reduce the effect of the gas. The advantage of this system is that at all times the patient can control the amount of sedation.
The other advantage is that after finishing the sedation within 10 -15 minutes you are able to leave and drive back to work.
This sedation removes anxiety and makes you feel very relaxed. You will still need local anaesthetic for the tooth to be treated.
