The dentist took her tooth out today. The colored spots I was seeing on her tooth was actually from the gums actually under her tooth. He said her baby tooth had become very transparent so that is why we were seeing those pinkish/reddish colors on her tooth. So now we just wait for her adult tooth to finish coming in. =)
This forum is for general medical advice, however I will do my best to respond to your situation.
Retained baby teeth may often need to be extracted in order to facilitate the eruption of the permanent tooth. The ultimate decision and timing if often left to the orthodontist who is the expert on these matters.
The dark spot may represent a cavity in the tooth. If your daughter is not experiencing any pain or swelling, you can probably wait to see the dentist as soon as they re-open the office.
