Sedation Dentistry in Allentown, PA

Nitrous oxide, commonly called “laughing gas”, is one of the safest sedatives in dentistry. Nitrous oxide is mixed with oxygen and delivered through a mask over the nose. It usually takes effect within a few minutes and wears off shortly after mask removal. 

Nitrous oxide help patients overcome their fear of dentistry. It makes you calm and relaxed during procedures. Your dentist places a small mask over your nose and you are asked to take a few deep breaths. Oxygen will be administered at 100 percent for a few minutes and then nitrous oxide will be increased gradually. You might feel tingling in your arms and legs or get light-headed. You will remain conscious and be able to respond to all questions asked. Once you are calm and relax, your dentist will administer local anesthetic but you won`t mind it. You will be comfortable during the entire procedure. After finishing the dental procedure, the nitrous oxide will gradually be decreased and then you will remain on 100% oxygen for a few minutes. At the end, the mask will be removed.
