Nitrous Oxide vs. Oral Conscious Sedation: Which One is Best?

It’s common for patients to experience dental anxiety when preparing for an upcoming visit or procedure. Past trauma, physical disabilities, and even strong gag reflexes can make the idea of a dentist poking and prodding inside your mouth one you would prefer to avoid. Dental professionals understand these concerns, which is why many offer nitrous oxide and oral conscious sedation to ensure a more comfortable experience, but which one is right for you?

Why You Might Choose Nitrous Oxide

Nitrous oxide, also referred to as laughing gas, is a milder solution that combines odorless and colorless nitrous oxide with pure oxygen to produce a relaxing effect. Inhaled through a nasal mask, you experience greater comfort and euphoria in the treatment chair.

It is often recommended to help “take the edge off” when requiring a dental cleaning or minor restorative procedure, such as a tooth-colored filling.

The effects of nitrous oxide come on quickly, so that your dentist can begin to administer the dental care you need, all while team members continue to monitor and adjust your dosage.

Once everything is finished, the gas will be turned off and the mask removed, allowing you to breathe pure oxygen for a few minutes. Afterward, you are free to resume normal activity and drive yourself home or back to work.

Why Oral Conscious Sedation Might Be a Better Option

Oral conscious sedation is delivered as a prescribed pill, which you will be required to take at a specific time before your appointment. Depending on the type of medication your dentist provides, you will begin to feel the effects by the time you reach their office. This is why you will need a family member or friend to drive you to and from your appointment.

This slightly stronger form of sedation is recommended when multiple or complex procedures are required, or if you have moderate to severe dental anxiety.

Once your dentist begins working on your smile, you will be in a deep state of relaxation. Unlike general anesthesia, you will remain aware enough to respond to your dentist’s cues. However, you will remain unbothered by your surroundings.

After your procedure is complete, you can expect to spend the day resting comfortably at home.

Both sedation methods are highly recommended because of their proven effectiveness and safety. Whether it’s minor nervousness you need to overcome or more serious anxiety you need help with, your dentist offers effective solutions to help you feel comfortable during your visit.
