SEDATION / NITROUS OXIDE (LAUGHING GAS)

Nitrous oxide (N2O/O2) sedation, also known as laughing gas, is a safe and effective method to help patients relax during dental treatment. It is administered through a nasal mask. You remain awake and responsive but feel calm and comfortable. Effects wear off quickly once the gas is stopped.

DESCRIPTION OF TREATMENT

You will breathe a mixture of nitrous oxide and oxygen through a comfortable nasal hood. The concentration is adjusted for your needs. You may feel light, tingly, warm, or euphoric. Local anesthesia is still used for pain control as needed. At the end of treatment, 100% oxygen is given for several minutes to clear the nitrous oxide from your system.

BENEFITS

• Reduces anxiety and fear, making dental visits more tolerable
• Raises pain threshold and can reduce gag reflex
• Fast-acting and effects dissipate rapidly after treatment
• No "hangover" for most patients - you can usually drive yourself home

RISKS AND POSSIBLE COMPLICATIONS

• Nausea or vomiting (especially if you ate a large meal before treatment)
• Temporary dizziness, headache, or disorientation during or after
• Paradoxical reaction (increased anxiety or agitation instead of relaxation) - rare
• Allergic reaction (extremely rare)
• Respiratory depression or inadequate oxygenation if over-sedated (monitored closely by staff)

Not recommended for patients with certain conditions: severe respiratory disease, recent ear/sinus surgery, pregnancy (first trimester especially), vitamin B12 deficiency, or current use of certain medications. You must inform us of any changes in health, pregnancy, or medications before each visit. You should not eat heavily before nitrous oxide appointments.

PATIENT / GUARDIAN RESPONSIBILITIES

• Arrive with an empty or light stomach (no food or drink for 2 hours prior is ideal).
• Inform us immediately of any discomfort or unusual feelings.
• Remain seated until staff clears you to stand and walk.
• Do not drive if you feel any lingering effects (rare).
