Nitrous Oxide (N2O) Sedation Dentistry in New Haven, CT

N2O sedation dentistry from our New Haven dental offices.

For those who fear going to the dentist, N2O sedation can be a smart solution. Although there are many different types of sedation your Long Wharf Dental Group dentist may recommend, nitrous oxide is one of the most common and frequently used methods of anesthesia. This time-proven sedation method has helped millions of uneasy dental patients control their discomfort so that they can receive the dental care they require.

What is N2O sedation?

Discovered in 1783 by an English scientist named Joseph Priestly, nitrous oxide (N2O) has been safely and effectively used as anesthesia in medical and dental environments for more than a century and a half. Many people may be more familiar with the unofficial term, laughing gas.

N2O is actually the scientific code for nitrous oxide, a mild form of gas that helps patients relax and remain comfortable throughout necessary dental and medical procedures. When used by a trained professional, N2O sedation is generally safe and effective for patients of all age groups, including children and the elderly.

Why N2O sedation?

If your Long Wharf Dental Group dentist chooses N2O sedation, most likely it will be to help you remain comfortable during an upcoming dental procedure. Nitrous oxide is administered to alleviate discomfort and reduce anxiety. The goal is keep you as relaxed as possible so that you can receive the timely dental care you need.

How nitrous oxide is administered for dental procedures.

Just prior to your procedure, our well-trained sedation experts will place a mask over your nose. You will then be asked to breathe normally while the appropriate dosage of nitrous oxide is administered. Within minutes, you may notice a feeling of giddiness or euphoria. This will be the laughing gas at work.

How nitrous oxide may affect you.

Although the laughing gas will relax you, you should remain conscious and able to think clearly and rationally. You should also be able to communicate freely at all times with your Long Wharf Dental Group staff. Most patients are fully capable of responding to speech and touch, even though they experience little pain or discomfort. Some patients also notice a feeling of lightheadedness, tingling in the arms or heaviness in their legs. These responses are all perfectly normal.

How long do the effects of N2O sedation last?

Once under the effects of nitrous oxide sedation, you should remain comfortable throughout your dental procedure. The dentist will carefully control the amount of nitrous oxide you receive to keep you in just the right state of relaxation, yet alert enough to respond to our staff. Once the procedure has been completed, most patients quickly recover alertness. In most cases, patients are able to drive safely soon afterward.

Is N20 sedation the best form of sedation for me?

As mentioned previously, nitrous oxide is a safe and effective form of sedation for patients of almost any age. If you have any specific medical concerns, check with your physician before your procedure. You should also discuss any related concerns with your Long Wharf Dental Group dentist or staff. Our sedation experts will always take your concerns into consideration before administering any for m of anesthesia, regardless of the method chosen.
