Hello Mr/Miss Tan,
Thank you for your enquiry. Your son most likely has this condition called " chromogenic bacteria stains". He may or may not grow out of it, but most of the time this condition does not persist to adulthood.
If the staining is severe, it can be quite upsetting for the child and parent, and we usually treat this condition with probiotics for the mouth in addition to polishing the teeth.
Just to be sure, you should bring your child to the dentist to make sure the black spots are not decay.
Although all general dentists who have graduated have had training in treating children, not all general dentists have the affinity or special interest to do so. It is important that you find a dentist who is good with handling children and is patient and caring towards them.
Sometimes such a dentist is hard to find, and a good place to start is by asking friends or family for recommendations . I echo Dr Lam's sentiments that sometimes it is necessary to send your child to see a specialist peadodontist.
I hope this information is useful for you and all the best!
