Dear parent, root canal treatment is a common procedure in milk teeth in children when they are infected. It can be done in children as young as 1.5 or 2 years. If you are not interested in getting RCT done, you can get it removed but it is associated with loss of tooth and can cause loss of confidence in children as permanent teeth will start eruption around 6-7 years. Please get the treatment only from Pediatric dentist only
