Novelty in the Children’s Dentistry – sedation with nitrous oxide (laughing gas)

Sedation is one of the methods for making dental treatment more pleasing and simpler. This method reduces fear and anxiety. Sedation with nitrous oxide is recommended for children from the age of six that are afraid of the dentist but are at an age capable of cooperating.

How does it work?

  • During sedation your child is breathing a mixture of nitrous oxide and oxygen gases through his or her nose with the help of a special nose mask, and at the same time the dental treatment is being carried out.
  • Your child does not fall asleep during sedation and is fully conscious, but feels a lot more relaxed and calm.
  • The child can speak and express his or her feelings during the procedure.
  • Most of the children feel pleasant warmth, relaxation, sleepiness, and a light tingling in their arms and legs during sedation. As soon as sedation is stopped, these feelings go away completely in 5-10 minutes.


  • Sedation raises the comfort of the patient, as well as reduces fear and anxiety.
  • It is a safe procedure used in children’s dental medicine around the whole world.
  • The nitrogen gas has a short-term effect, therefore you can go home soon after the treatment.


  • Some children feel nauseous or sick after the procedure, which is why it is very important to observe the instructions provided by the doctor regarding eating restrictions before sedation.


Before the visit:

  • It is advisable for the child to have only a light meal not later than 2-4 hours before the procedure. It is allowed to drink water up to 2 hours before the procedure.
  • Parents or legal guardians must come to the visit together with the child.
  • Take out contact lenses, remove bijouterie, piercings that might make it difficult to carry out the procedure.
  • Warn the doctor about illnesses and allergic reactions, as well as medicine that your child is taking.

After the visit:

  • Although 30 minutes after the completion of the procedure there is no more N2O in the organism, look after your child for approx. 2 hours after the visit.

Please take notice!

  • If your child is feeling sick or has caught a cold, the visit has to be cancelled.
  • During the first visit you will be consulted on the treatment process, a treatment plan will be formed, and the required instructions will be given. Dental treatment will not be carried out during this visit, but a sedation suitability evaluation will be provided for your child.
  • Feel free to ask any questions.
  • Sedation is not included in the list of services paid for by the state. The consultation and dental treatment with sedation is a paid service in accordance with the pricelist of the Institute of Stomatology.
