Dental Fear and Anxiety is Far Too Common

If you are one of the billions of people who suffer from dental fear, there is hope. Dental Specialties Northwest specializes in dental sedation for people who can’t stand to sit in the dental chair.

The only dental spa in Seattle that people actually fly across the country to visit, Dental Specialties Northwest understands how frustrating dental anxiety can be and has the best solutions for mild to severe dental fear.

Dental Fear Makes Things Worse

One of the biggest issues with dental fear is that it only makes things worse. That small ache at the back of your mouth will only get bigger. In fact, a small filling takes less than an hour to complete.

If you leave that little cavity to its own devices, it will grow making the hole larger and deeper. A large cavity usually requires more time and intensive treatment such as root canal therapy.

The Problem with Dental Fear

Dr. Rhys Spoor and Dr. Thomas Sweeney from Northwest Dental Specialties cannot stress the importance of regular dental visits. Twice yearly, or more frequently if you suffer from diabetes or other diseases that affect oral health, are vital for oral and overall health.

According to the Mayo Clinic, the link between oral and overall health cannot be dismissed. Dental fear only adds to the problem with missed dental appointments.

Inflammation causing bacteria is the culprit. Red, swollen, and bleeding gums have been linked to heart disease and stroke because bacteria enter the bloodstream thanks to pockets between the teeth and gums. Regular dental checkups in Seattle prevent gum disease.

Gum Disease Doesn’t Go Away

Northwest Dental Specialties are experts when it comes to periodontology. Periodontology focuses on inflammatory disease and the bacteria that destroy the tooth’s supporting structures.

There are two types of gum disease, gingivitis, which is curable and periodontal disease, which is not. While periodontits is easily controlled with frequent treatments from your Seattle dentist, it is not curable.

Sedation Dentistry for Dental Anxiety

The team from Northwest Dental Specialties offer Oral Conscious Sedation, Nitrous Oxide, or Laughing Gas, and IV or Intravenous Sedation.

Oral Conscious Sedation

This type of sedative is prescribed the night before and/or an hour before the procedure. Oral conscious sedation means you are conscious, but will not remember much, if anything about your dental treatment. It is important to ask someone to escort you to your dental appointment and back home again as you will still feel the effects of the sedative.

Laughing Gas or Nitrous Oxide


This common type of sedation for dental fear allows you to stay conscious enabling you to communicate with your doctor during treatment. Also called Laughing Gas, you breathe in gas through a tube and a mask while undergoing the procedure. Once Dr. Spoor or Dr. Sweeney removes your mask, you are free to drive yourself home from Dental Specialties Northwest.

IV Sedation for Dental Fear

People suffering from severe dental fear or for people that are undergoing multiple procedures, IV Sedation or Twilight Sleep Dentistry allows you to relax. While you won’t be sleeping, you’ll need to contact a driver to take you to and from your dental appointment. Administered through an IV, you won’t remember the treatment.

You don’t have to suffer from dental fear. Call and schedule an appointment with Northwest Dental Specialties today.
