There are many patients who are anxious about going to the dentist. It’s a fear they may not be able to overcome, so they can’t get the treatments they deserve. If you find yourself in this boat, then one way you can make your visits easier is with dental sedation. You may not know too much about it, but some things you might see online are myths that may stop you from getting it. So, here is the truth behind three common misconceptions.

Myth #1: You Will Go to Sleep with Dental Sedation

Many people are worried that getting dental sedation means they will fall asleep with it. They don’t like the idea of going unconscious, but this isn’t the case at all. No matter if you’re getting laughing gas (also known as nitrous oxide) or oral conscious sedation, you won’t be put to sleep.

The goal for these is meant to help you relax, so you might actually feel so calm that you doze off by yourself. The comfort you feel is to blame, but whichever you get won’t make this happen. Your dentist will be able to wake you up with a couple of nudges, and you can follow simple directions while answering easy questions.

Myth #2: It’s Unsafe to Get Dental Sedation

With the couple of different types of dental sedation there are, many people can generally find one that works for them. For instance, nitrous oxide offers the mildest effects. It’s a gas that you breathe in, so it’s often used for kids and adults alike.

While there are a few cases where it’s not safe, your dentist can help you determine that it will have no complications. They’ll consider things like pregnancy, previous experience with sedation, certain medical conditions, and allergies to make sure it’s a great and effective option.

Myth #3: Dental Sedation is Only Available for Complex Treatments

Since you can feel more relaxed with dental sedation, you may imagine it’s for those in-depth and complex treatments people dread, such as wisdom tooth extractions or root canals. While it’s used in these services, you can opt to get it during something like a simple cleaning.

What comes into account is the appropriate strength of sedation. Laughing gas and oral conscious sedation offer different levels, with the latter being stronger. You won’t be able to drive if you get that one, so you may choose nitrous oxide instead if it’s a minor service. That way, you can feel more relaxed regardless of the treatment you’re getting.

If you have any worries about this type of dentistry, then feel free to talk to your provider. They are happy to give you the facts so you feel confident choosing it for your visits.
