Medical negligence and its remedies in Dubai

Dental malpractice:

My daughter had a root canal done by a specialist pediatric dentist at a major hospital in Dubai and final reports and doctor claimed it was completed.

After that, the final payment was made and we were given a form for an insurance claim that everything was completed.

However, after going to another establishment, X-rays showed the root canal was not completed and the child is required to go through the whole procedure again causing mental agony and pain.

My child is not willing to go to any dentist much alone the same dentist because of the traumatic events and pain she endured of the 1st root canal which was supposedly done over 3 sittings.

I contacted the 1st hospital and they agreed in writing that it was a mistake.

The doctor also has called me personally to apologize and he would carry out the procedure including additional services free of cost.

My child is 3 years old and traumatized and unwilling to go to any dentist.

What are my options to claim?
