Sedation Options

Laughing gas mask over mouthWe pride ourselves on gentle dentistry. But even then, some people need a little extra help when it comes to relaxing in the dentist’s office. Especially if they need a slightly more involved or lengthy procedure.

As a licensed sedation dentist, Dr. Downing Moua has been providing safe and effective sedative options for over 20 years. His hospital training and careful patient selection ensure that this service is extremely safe for each of our patients.

Who Should Request Sedation?

Sedation is an excellent add-on for anyone who feels anxious, nervous, scared, has a sensitive gag reflex or simply wants the highest level of relaxation. We also recommend sedation if you require multiple procedures, just to help you feel at ease for a longer appointment.


Nitrous Oxide — Laughing gas is a gentle and fast-acting analgesic sedative. You’re completely alert, but it feels as if you’ve had a couple of glasses of wine. Nitrous oxide starts working within just a few minutes and is just as quick to reverse at the conclusion of your procedure. You can even drive yourself home afterward.

Oral Sedation — Occasionally we also offer conscious oral sedation, which is similar to taking Xanax combined with nitrous oxide gas. Although you’re still conscious of what’s going on around you, you simply don’t care much about it all. This sedation option does take a little extra time to wear off, so you’ll need to have a friend or family member drive you to and from your appointment.

Are there complications from sedation?


Adverse reactions to sedation medications are extremely rare. To minimize potential risks, each patient undergoes an extensive medical screening prior to their planned procedure.

Can sedation help if I have a sensitive gag reflex?

Absolutely. If you have a hyperactive gag reflex that makes dental treatment difficult, sedation can naturally help calm it.
Is sedation covered by my insurance?

Oral medications are usually covered by your insurance, but nitrous typically is not. Fortunately, the fee for laughing gas is quite modest, making it accessible to most of our patients even if they don’t have insurance coverage.
How long does it take for the sedative to wear off?

Nitrous oxide sedation is reversible within 5-10 minutes and there are no lingering after- effects. However, if you take an oral medication for your procedure it can take several hours to completely wear off.
Can I have nitrous oxide added to my appointment?

Feel free to request laughing gas during any dental procedure, whether it’s a cleaning or something like a crown. Nitrous is easy to add on when you’re feeling a little anxious and just need to take the edge off.
Can I eat or drink anything prior to my sedation appointment?

We try to schedule sedation appointments early in the morning when you feel well rested. It’s best to come in on an empty stomach, just in case you get a little queasy.
Is sedation safe for my child?

Nitrous oxide sedation is routinely used on children and teens during their required dental care.
