Children's Dentistry

At Willesden Dental Clinic, Our Friendly Staff Will Ensure that Your Children are as Comfortable and as Happy as Possible.

It is recommended that your children should visit the dentist with you as soon as possible. You should then take them regularly, as often as your dentist recommends.

Your dentist will give your children dental health care advise as children grow up. Emphasis is placed on prevention of dental health problems rather than waiting for them to arise.


Relative Analgesia for Children for a Relaxed Happier Experience

Relative analgesia, also called “inhalation sedation”, involves the use of nitrous oxide and oxygen to make a dental treatment procedure a more comfortable one for a child (the patient). Relative analgesia does not make a child fall asleep, but instead puts him or her in a completely relaxed state – enabling the dentist to proceed with the necessary dental treatment without putting the child through a traumatic or fearful experience.

Relative analgesia for children will be discussed by the dentist with the parents, as well as with the child (the child) himself. The child will usually be shown the equipment to be used for the relative analgesia procedure, so that he or she can first be familiar with how it looks like (and how it works) – before the equipment can actually be put in use in a succeeding dental appointment. This initial consultation will also usually involve the discussion of the dental treatment that needs to be done (on another dental visit), as well as getting the consent of parents for the use of relative analgesia along with the dental treatment/procedure.

How does Relative Analgesia Work?

Inhalation sedation or relative analgesia is composed of a mixture of nitrous oxide and oxygen – the usual ratio is 70% oxygen and 30% nitrous oxide, although a 50% oxygen-50% nitrous oxide ratio is sometimes used in medicine (referred to as “entonox”, or “gas and air”). Relative analgesia in dentistry works as a maintained level of conscious sedation, raising the patient’s threshold for pain and placing him or her in a relaxed state – without falling completely asleep in the process.

How is Relative Analgesia Administered?

A rubber mask is used to fit over the child’s nose and mouth areas; the rubber mask should be comfortably fitted so that it allows the child to inhale the oxygen and nitrous oxide (laughing gas) while the dentist proceeds with the necessary dental treatment at the same time. The inside part of the rubber mask usually has an attractive scent (such as mint, vanilla, or strawberry) – to make the experience a more pleasurable one for the child. Throughout the procedure, the child will be conscious of his or her surroundings (and will be able to understand any instructions coming from the dentist) – but will be in a completely relaxed, comfortable state.

The equipment used to administer relative analgesia is composed of a supply of the compressed gases (nitrous oxide and oxygen), and the apparatus (connected to the rubber mask) which will deliver the gases. The dentist, along with a properly trained and certified dental nurse, will control the desired mix and quantities of the nitrous oxide + oxygen. The flow of compressed gases will be monitored with the help of pressure gauges and flow meters.

Who Will Benefit from Relative Analgesia?

Children who need dental treatments or procedures will benefit from the use of relative analgesia if they:

  • Have a moderate or severe fear of going to the dentist, or of undergoing a dental treatment;
  • Require tooth extractions, which might cause them to feel fearful or anxious during the procedure;
  • Have a strong gag reflex that may make it difficult for the dentist to proceed with the dental treatment effectively; the strong gag reflex may also result to a negative or traumatic experience for the child.

Advantages of Using Nitrous Oxide in Relative Analgesia
  • The use of relative analgesia is very safe – the child will be able to communicate with the dentist when needed; there are no negative side effects on body organs; and there are very few side effects.
  • Nitrous oxide works very rapidly in relative analgesia – the child will feel extremely relaxed and free from pain in about two to three minutes.
  • The administration of the compressed gases can easily be controlled or adjusted, so that the mixture can be administered only for the specific length of time that it is needed.
  • The level of sedation can be adjusted from one moment to another – the dentist or dental nurse can increase or decrease the sedation level as needed in any given time. These kinds of adjustments are not easily manageable or possible with other sedation techniques, such as IV sedation.
  • There is no feeling of having a hangover afterwards. Once the administration of relative analgesia has been stopped, the nitrous oxide will be eliminated from the body in three to five minutes.

What Will a Child Feel when Relative Analgesia is used?

Aside from being completely relaxed and comfortable, the sensations listed below are some of the most common ones that children will be experiencing when relative analgesia is used for a dental treatment:

  • Mild tingling sensation on the toes and fingers
  • Mild warmth and heaviness on legs and arms
  • Significantly reduced (or even eliminated) gag reflex
  • A sensation of floating
  • A sensation of being far away from the activities in the immediate surroundings – sounds, voices, or music may seem to be come from somewhere far away
  • Reduction or elimination of anxiety of being in the dentist’s clinic; no fear of undergoing the dental treatment
  • Reduced sensations or awareness of certain procedures, such as the administration of dental anaesthetics through injections.
