Dental sedation gas is a colourless gas that has a pleasing taste and odour. Before a dosage of sedation gas, patients will inhale one hundred percent oxygen through a mask or through a soft nosepiece. Afterwards, the sedation gas is combined with oxygen. Dental sedation gas usually takes effect in about five minutes.
When dental sedation gas is used for mild sedation, you will feel:
- Warm, relaxed and sleepiness
- Tingling sensations in your hands and in your feet
- Numbness in your mouth, feet, and hands
- Heaviness or lightness
- Changes in the way you hear sounds
- A sense that everything is wonderful
- In very rare cases, people will feel anxious
Dental sedation gas will not put you to sleep and you will still be able to respond to your dentist’s questions and requests. You may slur when you speak and you may take longer than usual to respond. In general, you will be very cooperative and relaxed. You will know when you are getting injected and there are times where you may even feel the injection. However, you will not be bothered and your breathing and heart beat will remain stable and normal.
You should feel normal and alert when the mask is removed although your motor skills and your attention could be affected for up to fifteen minutes. You should check with your dentist if you are leaving the dentist’s office sooner than fifteen minutes.
