Sedation Dentistry


Sedation Dentistry and Anesthesiology

Probably everyone feels some level of anxiety about going to the dentist. Whether it’s from past experiences or merely the idea of it, we know there are other places you’d rather be, doing things other than having a dentist working on your teeth. At Dental Specialties Northwest, when you meet with your dentist, be sure to talk about your anxiety. Providing a stress-free environment, and the right level of sedation is key to managing that anxiety.

Types of Sedation Dentistry Available

Nitrous Oxide

Also known as “laughing gas”, nitrous oxide is administered through a mask. You may feel relaxed, but you are conscious and able to communicate with us. Often, you can drive home after your procedure. The gas should not affect you once we remove the mask.

Oral Conscious Sedation

An oral sedative (pill). We prescribe the sedation medication that you will take. You will receive this medication an hour before your appointment. You will need to have someone drive you to and from our office.

IV Sedation

We use IV sedation when you need a deeper level of sedation. A driver to and from your appointment is a must.

Sedation Dentistry

In addition to Sedation

In addition to sedation, we have an anesthesiologist team on call. We can bring them in for your treatment, providing that extra level of safety and attention. The first step is to call and let our team know that you are interested in sedation dentistry for your next appointment. If, during your appointment, you decide you would like some sedation, don’t hesitate to let us know.

At Dental Specialties Northwest, we understand that visiting your dentist can feel intimidating.
