Laughing Gas (Nitrous Oxide) During Sedation Dentistry

The most commonly employed technique used in conscious sedation dentistry is inhalation sedation with nitrous oxide and oxygen (N₂0-0₂) or "laughing gas". It is estimated that approximately 35% of U.S. dentists use this technique to relieve dental anxiety.

The goal sought when laughing gas is used is to eliminate dental anxiety, making the patient more comfortable while the sedation dentist is able to more effectively complete the planned dental care procedure while the patient is sedated. Consult with your dentist to find out if this procedure right for you.

A small rubber inhaler will be placed over the patient's nose and adjusted so that the patient is comfortable. At this time, the patient will be breathing 100% oxygen.

Some patients at their first laughing gas visit will feel that they are not getting enough "air." The patient should tell the sedation dentist and he or she will provide them with even more oxygen to breathe.

Once the patient is comfortable breathing oxygen, the dentist gradually will introduce nitrous oxide. Over the next three to five minutes, the patient will be asked, "What are you feeling?" as the amount of nitrous oxide is slowly increased.

The signs and symptoms that most patients experience when receiving laughing gas include an 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 - a benefit to the sedation dentist (and patient) during the dental care treatment. Some patients will mention that their arms and legs feel "very light." Interestingly, other patients will say that their arms and legs feel "so heavy I can't even move them."

If either of these occurs to the patient, it is perfectly normal. The individual might notice that they are perspiring a little, too. This is a normal effect of nitrous oxide and oxygen dentistry.

The sedation dentist will talk with the patient throughout the dental care procedure and the individual 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, the patient feels that they are getting too much nitrous oxide or if they begin to feel uncomfortable, they should tell the dentist immediately and within seconds the dentist can adjust the flow of gases, and the patient will feel more comfortable again.

At the conclusion of the sedation dentistry treatment, the patient will once again receive 100% oxygen (for a minimum of three to five minutes). At the end of this time, the person should feel absolutely back to normal. If they still feel even a little bit sedated, the dentist should give the patient oxygen for a few more minutes.

Most dentists permit the fully-recovered laughing gas patient to leave the dental office unescorted and to resume their normal activities. In some situations where a patient recovers more slowly, they might be required to have an escort (friend or relative) drive them home.

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

Finally, laughing gas is highly recommended for apprehensive patients who have medical problems such as angina pectoris, persons who have had a heart attack, or persons with 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. Please discuss these with your dentist before treatment using laughing gas begins.

Dentistry and Medicine - A Partnership for Your Oral Health

A world of opportunities for dental health awaits us in the new dentistry. Using the old dentistry, dental care professionals did their best to provide a high quality of service given the state of knowledge and technology at that time.

Through advancements in treatment, research, and the desire of the dental care profession to do more and do it better, the new dentistry has emerged giving you a better smile. It is based on a foundation with specific characteristics that are of great benefit to us as consumers.

• Efficiency: Your time and your resources are valuable to you, and your dentist recognizes this. New dentistry treatment techniques and methods have considerably reduced the amount of time that the dental care now takes. The return on your investment in dental health is excellent.
• Comfort: Not only are the dental chairs and the dentistry office environment more comfortable and pleasant, improvements in the use of local anesthetics and new equipment provide more comfort than ever before.
• Collaboration: The dental relationship is now based on the value that you can derive from your dentistry team and what you want for your dental future rather than just on the techniques and procedures your dentist can do. Through dental continuing education, your dentist has the skills and knowledge to help you make decisions for your dental health in a positive and informed way.
• Predictability: New materials and advances in treatment provide you with opportunities to maintain your dental health throughout your life. With the innovative cosmetic and specialized dentistry approaches to reclaiming teeth that formally would be lost, your dentistry professional can help create and maintain teeth and gums. Predictable treatment, effective prevention methods, and the longevity of treatment are now part of any treatment plan.
• Thoroughness: Advances in assessment and diagnosis now enable dentists to make thorough evaluations of your overall dental and oral health. The outcome is a plan for your health that will give you peace of mind, knowing you can have a well-informed dentistry plan in place.
• Prevention: This characteristic of the new dentistry has received much publicity in recent years. It has been proven over and over again that there are several measures that you can take as a consumer of dental care to create and maintain your dental health in collaboration with your dental team. It bears repeating again -- flossing and brushing combined with regular dental hygiene checks are your greatest allies in maintaining your teeth and a bright smile.
• Precision: The new dentistry utilizes instruments and technologies that are far advanced from what was available even 15 years ago. Both general dentists and specialists have access to technologies that provide precision in diagnosis and treatment. The value for you is higher quality care.

The dental profession has established a strong foundation for a pleasant smile and a healthy dental future for all of us. Dentistry improvements are continuously being made to this foundation. You can choose to avail yourself of these improvements by asking your dentist, "What can help me to maintain my dental health?" They have the knowledge and the desire to help you.
