I guess visiting my motherland, getting my teeth done and flying back is very much cheaper!
Flight ticks to SL (up and down): 1500 QR
Appointment & Root Filling : 500 QR (Not even that!)
My Dentist is a registered maxillofacial surgeon who trained and studied in the UK and is really experienced (Golden Key Hospital - Colombo)
2000 QR + 2000 QR( For visa, stay and even going around the city if you are a foreigner!)
4000 QR for that is not bad at all eh? ;)
