We Cater to Cowards
We know that for some people, a visit to the dentist’s office isn’t something to look forward to. Dental procedures can bring out a lot of uncertainty regarding pain and the results. That’s why our team offers sedation dentistry services to help those who need it. Below you will find the many options we offer giving you the most pain-free dentistry and comfortable experience:

Starting with your first visit in our dentistry office, we open the lines of communication and gain an understanding of any possible apprehensions you may have towards dental care. Our patients occupy the full spectrum ranging from those with dental anxiety to patients who enjoy their dental visits. During treatment you are encouraged to communicate with us about your comfort level. If at any point you are uncomfortable, we make the necessary adjustments before proceeding.

Oral Conscious Sedation
For our patients with moderate to severe dental anxiety, who have a family member or friend who can get them to and from their dental visits, we recommend Oral Conscious Sedation. This requires the use of prescription anti-­anxiety medications in the benzodiazepine family. While under oral conscious sedation the patient tends to be very sleepy and unaware. While sedated the patient’s blood pressure, heart rate, and oxygen levels are closely monitored using a pulse oximeter. There is very little risk involved if the appropriate doses are administered and the patient is monitored.

Inhalation Sedation (“Laughing Gas”)
At our dental center in Columbia Falls, we have a highly committed and qualified team of sedation dentistry specialists ready to help you become comfortable with certain dental procedures. One of the methods we use is ‘laughing gas’.

Nitrous Oxide (N2O) is combined with Oxygen (O2) at a safe level and inhaled through the nose. Nitrous oxide can reduce pain, produce pleasant feelings, and sometimes create a slight numbing sensation. Patients often begin to feel its effects after breathing the gas for as little as two to five minutes. Some people experience mild lightheadedness. Others get the giggles, giving nitrous oxide its nickname. The effects of the gas only last a short time and wear off quickly once its administration is discontinued. This provides for the patient an increased level of comfort and a decreased level of anxiety. Laughing gas is great for those patients with mild to moderate dental anxiety, and because it has no long term side effects patients can drive to and from their appointment.
