Nitrous Oxide/Sedation

Top Dentist In Cottleville, MO

With modern medications and techniques, anxiety can be easily managed in a dental setting.  If you want sedation, but do not want to arrange a driver, you can have the mild sedative of nitrous oxide (laughing gas) to allow relaxation during your visit.

If you are having dental anxiety, then we can talk about options that can help you feel at ease. This can be done by administering the mild sedative of nitrous oxide (laughing gas) to help calm your nerves.

Nitrous oxide has been used for more than 150 years as a safe and effective sedative. It is the most commonly used sedative in dentistry, and is especially popular with patients who are anxious about dental work. Nitrous oxide helps people quickly feel calm and relaxed, and it also helps to take away any pain they may feel.

With nitrous oxide, the sedative is no longer in your system when the appointment is finished. Nitrous oxide is known to be fast-acting and quickly eliminated from the patient’s body after use, making it a smart choice for patients who have appointments with relatively short waiting periods between them.

Nitrous oxide is a gas that is commonly used in dental surgeries and other medical procedures to help patients feel less pain. One of the most interesting facts about nitrous oxide is that it’s quickly absorbed by the body and eliminated within minutes of leaving the patient.

Nitrous oxide, also known as NO2, is a gas that is used in dental surgeries. It’s quickly absorbed by inhalation and has a few effects on the human body. It helps to induce a state of euphoria and calm, which can be helpful for people who are experiencing anxiety during the procedure. Nitrous oxide is considered an anxiolytic (an anti-anxiety treatment).

There are other medications we can prescribe that you can take before you arrive (with a driver) which will also cause mild sedation so you are relaxed for your visit. Some people even choose to combine the two options to enhance the sedative effects.

Our mission is to make every patient feel comfortable and to limit anxiety as much as possible. By listening to our patients, we can better cater to your visit needs. We want our patients to know that they are not just a number or just another face, but that they are someone that we truly care for.

Levels of sedation:

Minimal (mild) sedation: You are awake, but medications make you feel more relaxed. There is a reduction in both anxiety and your level of awareness.

Moderate sedation: You are awake, but you feel groggier and there is a more significant reduction in anxiety and awareness. You will be able to respond to verbal commands and your protective airway reflexes are still intact. 

Deep sedation: You are near unconsciousness or are unconscious. Your airway reflexes are not intact and you need advanced airway support. This level of sedation is not offered at Majestic Dental.

I just had a new crown placement and it was extremely smooth. Everyone was very professional and I love getting the whole procedure in one day—no temporary!

I highly recommend Majestic Dental. I have been a patient there for many years. Jane is my hygienist and she is extremely kind, professional, hardworking, personable and answers questions very well and explains everything she is doing. Dr. Lear is an amazing Dentist who is very skilled, calming and makes you feel comfortable and at ease. I value and trust his opinion with any additional dental work I may need. The office staff is very knowledgeable and it’s easy to make appointments. Majestic Dental also has a beautiful brand new welcoming office which makes you feel comfortable as soon as you walk in. Thank you for the wonderful service I receive.

Today was my first time at this office. My insurance changed and I had to switch. Brandy was my hygienist. Even though I did not like the news, she was very kind and helped me with options. She was very pleasant to be around. Same with the dentist. He gave me several options to choose from. He was also very kind. I'd have to say A+. The office was beautiful and modern. The ladies at the front desk were also very kind. I have to say, I'm so glad my insurance changed because I didn't get options from the last dentist.

Impressive! When your super sensitive ADHD & Dyslexic & a 13 year old boy has nothing but really good things to say…. I’m in!! Charlene and Dr Sanford are incredible and I love how comfortable they make you feel. Both professionals explained step by step, that is priceless in my book and it really helps take some of the fear away, so thank you a thousand times! Miranda & Katie also took care of us on the administrative side , love the office vibes and the location , we found our new home dentist.

I had made my first appointment for a general cleaning but hadn't been yet to see them when a urgent dental issue arose. They were able to see me same day! The dentist spent quite a bit if time with me examining my mouth and teeth in question. He examined my jaw and the related muscles, performed several tests and discovered the issue. He explained in detail what he believed was occurring and what courses of action we could take. I was able to get scanned for a dental appliance with zero discomfort and they are fabricating it with pick up tomorrow. I felt such relief in knowing what was going on and having a plan of action to address the issue before it became a major dental issue. The rlentire staff was friendly and professional. I will HIGHLY recommend this office for anyone needing dental work!

I could not recommend this dental office enough! Dr. Lear and his team are so gentle and thorough while also providing high quality dental care, even while I go through pregnancy. Abbi was a fantastic dental assistant and was supportive while I had fillings done. They all made sure I was comfortable and provided me breaks as I needed!

Loving Majestic Dental! Dr. Sanford is great. Identifies areas that need treating… doesn’t invent treatments that don’t need attention. Hygienist Brandy is so pleasant and professional. Takes the time for a thorough cleaning. Even the front office is made up of pleasant efficient staff. Time well spent at this office.
