Sedation Dentistry

Nitrous Sedation

Drs. John and Joseph Barnhart understand that dental anxiety can prevent some patients from receiving the care they need. This is the reason they choose to offer sedation dentistry in the form of nitrous oxide. This sedative is combined with oxygen and is safe, effective, and easy to take. Your dentist places a small mask over your nose and you then inhale the nitrous oxide to achieve a relaxed feeling within minutes.

You Remain Awake but Comfortable

Nitrous oxide, also known as laughing gas, doesn’t put you to sleep although you may feel sleepy. You can still hear directions from your Vienna dental team and respond to their questions. Nitrous oxide effects fade almost immediately after removal of the mask.

Depending on the severity of your dental phobia, you may not have had regular cleanings in years and avoided more complex procedures that you needed. Your Vienna, MO dentist feels compassion for your situation yet desires for you to have optimum oral health. With sedation dentistry, you can get the dental work you need and avoid the need for more extensive procedures in the future.

The benefit of nitrous oxide is that it helps you feel relaxed for the duration of the visit. Without dental anxiety to hold you back, you will be able to participate in your treatment by responding to questions and requests. You can even have more than one procedure performed at a time using nitrous oxide.

Local Anesthesia

Local anesthesia is used by the Barnhart Dental team to numb a specific location in your mouth during a dental procedure. It blocks the sensory channels (nerves) at the site, so although you’re awake and responsive during the procedure, you won’t feel any work being done on that area of your mouth.

At Barnhart Dental, our goal is to make you feel relaxed and comfortable while you receive the treatment you need to ensure long-term oral health. If you require treatment for several issues at the same time, having them done simultaneously while using nitrous oxide is a good idea. It saves time because you won’t have to make several return trips to our dental practice. We look forward to caring for your dental needs.

Preparation Prior To Receiving Anaesthesia

At least 12 hours prior to receiving anesthesia or a sedative, it is highly recommended that patients stop smoking or using other tobacco productions, as tobacco intake dramatically slows the healing process.

All of our patients are given specific instructions by Dr. John or Joseph Barnhart, but in most cases, patients are required to fast from food and fluids for 8 hours pre-appointment time. Make sure you are accompanied by an adult who will be able to drive you home, as the sedative and anesthesia will still be affecting you. Ensure that you leave any jewelry at home, as that might interfere with the treatment. The Barnhart Dental team will work with you closely prior to any dental treatment to ensure that your experience is safe and comfortable.
