Fear of dentists is caused by a direct experience or a suggestion. Children and grown adults can develop both rational and irrational fears of dentists, dental procedures and dental clinics, making it more difficult for them to accept treatment. Some people even end up having to endure bad oral health because of this. They avoid visits to the dentist and would rather endure pain, just so they can stay away from treatment. The use of nitrous oxide changes things; when the gas is administered, the patient relaxes and their fear and anxiety is controlled, so the procedure can go on smoothly and favourable for the patient and the operator.

The use of nitrous oxide is very helpful; and if you are considering receiving yourdental treatments with it is important that you know more about it. The following are some of the frequently asked questions about the application of nitrous oxide in dental treatments:

Is the use of nitrous oxide safe?

The application of nitrous oxide is fairly safe. Nitrogen on its own may not be safe, but the mixture of nitrous oxide that is used in treatment applications have about 70% oxygen and only 30% nitrogen, or 50% nitrogen and 50% oxygen for more serious medical treatment procedures. Etonox, the term that refers to the perfect mixture ought to be safe as long as it is administered at the right dosage.

How is nitrous oxide delivered to the patient?

Nitrous oxide is an invisible gas and it is delivered to the patient the patient through a nasal hood or a cannula. This administration of the gaseous substance can be controlled by a knob and switch, to make sure that the appropriate doses are delivered to the patient. The device is regulated by a flow meter that helps you monitor the level of gas in the patient’s system, determining whether or not it is safe for the patient.

What changes should I expect on my body when the gas begins to take effect?

As soon as nitrous oxide is taken in by the patient, it will take effect and there are some changes that can be expected. Paresthesia is the first effect of nitrous oxide inhalation. This is characterized by the tingling sensation on the upper and lower extremities, as if a continuous vibration is felt. It is also possible for you to feel a little warm, and when the sedation has gone deeper, you can feel euphoric. You will feel as though you are floating, until you enter a dream state. At this stage you will feel very heavy and you will no longer be able to speak and keep your eyes open.

Why does nitrous oxide work?

The use of nitrous oxide has become very popular to use in dental treatments because it resolves anxiety and fear. This works because as soon as the nitrous oxide gets into the patient’s system, most of your senses will be depressed, lowering your sense of touch, your sense of hearing and your sense of feeling pain.
