Dental treatment under general anaesthesia: special needs, children, severe fear

Some people cannot be treated in an ordinary dental chair: a person with a disability who cannot tolerate instruments in the mouth, a young child with many cavities, an adult frozen by fear of the dentist. For them, treatment can be carried out in an operating theatre, under general anaesthesia, with an anaesthesia team. Dr Seyfeddine Ghenia, a general dentist in Rabat, treats these patients, at the request of the family or of the patient, after an assessment. Consultations can be held in English. This page explains who it is for, how it works and what to know before deciding. It is for information only: only an examination, followed by the anaesthetist's opinion, can tell whether it is the right option.

Who is it for?

General anaesthesia is considered when treatment is needed but impossible, or too distressing, in the chair:

• people with a disability: autism, Down syndrome, cerebral palsy, intellectual disability, behavioural disorders, neurological conditions;
• young children with many cavities or an abscess, who cannot cooperate because of their age;
• severe dental fear (phobia), when other approaches have not been enough;
• a very strong gag reflex that prevents opening the mouth or taking an X-ray;
• long or numerous procedures that are better grouped together, such as several impacted wisdom teeth (see the guide on wisdom teeth).

General anaesthesia is not the first choice. When possible, short familiarisation visits, adapted explanations or other approaches are tried first. It is offered when these are not enough or not suitable, and the decision is made with the family and the anaesthetist.

How it works

1. The dental consultation. The mouth is examined as far as the person allows, the family is heard and the medical records are gathered. The aim is a complete treatment plan, so that everything is done in one session: fillings, extractions, scaling, root canal treatments when they are feasible.
2. The anaesthesia consultation. It is mandatory. An anaesthetist examines the patient, checks their conditions and usual medication, and decides whether general anaesthesia is possible and under what conditions.
3. Treatment day. The patient comes fasted, following the anaesthetist's instructions exactly. They fall asleep, then all the treatment is carried out during sleep, in an operating theatre, under continuous monitoring.
4. Waking up. The patient wakes up in the recovery room, with a companion as soon as possible. Discharge is often on the same day, depending on the anaesthetist's opinion.

Preparing the day: tips for families and carers

• Bring the list of medication and the medical records (reports, allergies, epilepsy, heart conditions).
• For an autistic or anxious person: prepare them with simple words or pictures, bring a familiar object, and tell the team what reassures or upsets them.
• Plan for a companion for the whole day, and a lift home.
• Write down your questions: expected duration, planned treatment, and what will be done if another damaged tooth is found during the anaesthetic.

After treatment

Mild pain, some bleeding after an extraction or a slightly sore throat are common in the first days. The team gives you written instructions: food, hygiene, and warning signs that should make you call back (fever, swelling, bleeding that does not stop).

What matters most comes next: prevention. The anaesthetic treats the damaged teeth, but it does not change what caused the cavities. Without assisted brushing, less sugar and regular check-ups, new cavities can appear and lead to another anaesthetic. A check-up is therefore planned a few weeks later, then regularly (see the guide on tooth decay).

What studies show

• In children, dental treatment under general anaesthesia clearly improves oral health-related quality of life (pain, sleep, eating), according to a meta-analysis of 36 studies (BMC Oral Health, 2025, PubMed).
• In young children, quality of life improves, but dental fear does not clearly decrease after the anaesthetic (BMC Oral Health, 2025, PubMed): the child still needs to get used to the dental office afterwards.
• In adolescents and adults with special needs, root canal treatments done under general anaesthesia succeed in 81.5 to 90% of cases after at least one year, according to a systematic review (Odontology, 2024, PubMed).
• In adults with special needs, a review concludes that anaesthesia or sedation often remain necessary, and that preparing the setting and teamwork are essential for safety (Health Policy, 2025, PubMed).

Booking an appointment

Consultations take place in Rabat; the place of treatment is given when you book. The easiest way is to send a WhatsApp message stating the patient's age, their situation (for example "autism, 9 years old"), their medication, what bothers them and what has already been tried. See the appointment section.

Frequently asked questions

Is general anaesthesia for dental treatment dangerous?

Like any anaesthetic, it carries rare risks, which the anaesthetist assesses during the consultation; the anaesthetist decides whether it is possible and under what conditions.

Can all the treatment be done at once?

Yes, that is the aim: the treatment plan is prepared in advance so that every tooth that needs it is treated in a single session.

Can my autistic child be treated under general anaesthesia?

Yes, when treatment is needed and cannot be done in the chair; the preparation takes into account the child's routines and what reassures them.

Do you have to stay in hospital?

Usually not: discharge takes place on the same day, after waking up and depending on the anaesthetist's opinion.

Can I ask for general anaesthesia because I am very afraid of the dentist?

Yes, you can ask for it; it is discussed after the examination, together with the other possible options, and the final decision also rests with the anaesthetist.

How much does dental treatment under general anaesthesia cost?

The cost depends on the number of procedures, the duration and the operating theatre fees; it is explained before any decision, and you can check with your health insurer.
