Sedation Dentistry

Easing dental anxiety”

If anxiety prevents you from having dental work done, NuSmile Sedation Dentistry can help you relax and make the most of your visits to NuSmile. Sedation Dentistry is completely safe and efficient and can be used for a variety of cosmetic dentistry treatments such as porcelain veneers, dentures, and dental implants. In fact, we can do many dental care procedures during the same visit.

How Sedation Dentistry Works

Sedation Dentistry — or Conscious Sedation Dentistry — is sometimes referred to as “Sleep Dentistry.” However, patients are usually awake with the exception of those who are under general anesthesia.

As a Conscious Sedation Dentistry patient, you will totally relaxed — you won’t feel any discomfort during your dental treatment, as if you were asleep. Medication will be administered orally or intravenously based on your needs.

Laughing Gas

The most common technique used in Conscious Sedation Dentistry is inhalation sedation with nitrous oxide and oxygen (N20-02) or "laughing gas." Approximately 35% of U.S. dentists use this technique to relieve pain and dental anxiety.

Who is a Candidate For Laughing Gas?

Laughing gas inhalation sedation is highly effective in the management of mild to moderate levels of dental anxiety. It’s also an excellent technique in persons who are extreme gaggers — laughing gas usually eases and minimizes gagging in most patients.

Laughing gas is also highly recommended for apprehensive patients who have medical problems such as angina pectoris, persons who have had a heart attack, or high blood pressure, asthma or epilepsy.

Inhalation Sedation Dentistry should not be used with persons who are claustrophobic or with persons who are unable to breathe through their nose. NuSmile will help determine if you’re a good candidate for laughing gas before treatment using laughing gas begins.


Laughing gas helps to ease dental anxiety, making you more comfortable while we complete the planned dental care procedure. A small rubber inhaler is placed over your nose and adjusted so you’re comfortable. At this time, you will be breathing 100% oxygen.

During the first laughing gas visit, some patients feel they’re not getting enough "air." Simply let us know and we will provide even more oxygen. Once you’re comfortable breathing oxygen, we will gradually introduce nitrous oxide. Over the next three to five minutes, you will be asked, "What are you feeling?" as the amount of nitrous oxide is slowly increased.

What You’ll Experience

  • Initial feeling of lightheadedness, which gradually leads to an all-over feeling of warmth.
  • Many persons mention a comfortable "vibrating" or "humming" sensation.
  • It is common to feel one's fingertips and hands become "numb." This same sensation may develop in the mouth – an added benefit during the dental care treatment.
  • Some patients mention that their arms and legs feel "very light."
  • Other patients say their arms and legs feel "so heavy I can't even move them."
  • Some people might notice they are perspiring a little, too. This is a normal effect of nitrous oxide and oxygen dentistry.

Your NuSmile Conscious Sedation Dentist will talk to you throughout the dental care procedure; you will be able to respond without any problem. This is a major advantage, and a safety feature, of Conscious Sedation using laughing gas.

If, at any time during the procedure, you feel you’re getting too much nitrous oxide or if you begin to feel uncomfortable, we can immediately adjust the flow of gases to help you feel more comfortable again. At the conclusion, you will once again receive 100% oxygen (for a minimum of three to five minutes). At the end of this time, you should feel back to normal. If you still feel even a little bit sedated, we’ll provide oxygen for a few more minutes.

Most dentists permit a fully recovered laughing gas patient to leave the dental office unescorted and to resume normal activities. However, if a patient recovers more slowly, they may need an escort (friend or relative) to drive them home.
