Nitrous oxide sedation

If you haven’t heard of nitrous oxide, you have probably heard its nickname: laughing gas. Dental anxiety is an issue that affects many people and can even keep some from attending their regular cleanings and checkups. Fortunately, there are a variety of sedation options available today to help you feel more comfortable during your visits. Here are a few interesting things that you should know about nitrous oxide sedation before your visit.

Nitrous Oxide Sedation Isn’t New!

Medical professionals have been using nitrous oxide for more than 200 years now. It was first discovered in 1793 by an English scientist named Joseph Priestly. This is still one of the most commonly used anesthetics today, particularly in dentistry. It helps to take the edge off your treatment, allowing you to be more relaxed.

The Nitrous Oxide Administration Process Is Simple

Nitrous oxide sedation doesn’t require any shots or IVs for administration. Instead, you just need to breathe in a mixture of oxygen and nitrous oxide through a mask that your dentist will place on your face. Just breathe in normally and you will absorb the anesthetic through the lungs and feel the sedative effects. Once the mask has been removed, the effects will wear off quickly by just breathing in and out.

Nitrous Oxide Sedation Has Many Benefits

Dentists love to use nitrous oxide for a few reasons. The amount of sedation can easily be adjusted and works very rapidly. It is very safe for the brain, heart, liver, lungs, and kidneys. Nitrous oxide is also great for younger patients, those with disabilities, and people with dental anxiety. No needles involved!

Nitrous Oxide Sedation Is Safe When Administered by a Professional

Nitrous oxide sedation is perfectly safe. The only danger associated with it is disorientation, but you will be staying in the dental chair until the effects fully wear off, so you have nothing to worry about. It will only take a few minutes for you to feel like yourself again. You won’t even experience the “hangover” effects that are associated with other types of anesthetics. You can even drive yourself home afterward.

Getting nitrous oxide sedation for the first time can sound intimidating, but you don’t have anything to be concerned about. This is used to relax the body and mind so your dental procedure will be a breeze!
