9 y.o with black line on gums and black tooth?

Question

My daughter just said "Mom look at this...". Her top gums have a black line across her gum line. She also has a bad cavity on top (the tooth is turning black and cracked). On her bottom gums, they seems to be a space inbetween her gums and teeth. There is also a thin black line across some of them, but not like up top. Up top it is a thick line. I am wondering what this is? I am going to call the dentist on Monday, but have never seen anything like this and am just curious. She has seen a dentist routinely, but I just switched dentists and realized that it has been about a year since her last visit. She has had problems with her teeth since they came in (absesses, teeth pulled, caps, crowns, spacers etc.). What is with the black lines? She said that they do not hurt, but also said that it hurts when she brushes if the brush touches her gums. She is good about brushing and brushes twice a day (in the morning and at night) usually.

Answer 1

Definitely sounds like some bacteria got in there and she's got an infection.

She needs to brush ALL the way to her gums! Even if it hurts for a little while, her gums will toughen up and get used to the brushing. And a little bit of blood while she's getting used to it is normal, my gums still bleed a bit if I go a bit too long without brushing.

Definitely off to the dentist though! Hopefully she won't need a root canal! I hope it's a baby tooth. :(

Answer 2

Sounds like she anit brishing her teeth good.. A 9yr old should have a rotten tooth at that age. I would show her how to properly brush her teeth!

Answer 3

I bet she is brushing her teeth, but just not getting in there good enough. There is a mouth wash that has a solution that leaves the leftover gunk a blue color to show where she needs to brush more. That may help a little. But this doesnt really answer your question, does it? haha. I have never heard of this before. Maybe that cavity is causing her to need to have a root-canal done, it sounds like some kind of bacterial infection got into her gums, maybe by a small cut from brushing to hard, or anything. Hope I helped. Good luck with her and I hope everything turns out to be ok with her.

Answer 4

It could be an infection that has somehow snuck in there. Especially at her age, you just never know! Good luck at the dentist though!

Answer 5

IF she IS brushing her teeth twoce a day, she should not be having all that trouble, unless maybe a nutritional deficiency.........(calcium, vitamin d......)

----when I was a kid they had these red chewable tablets at the dentist to give to kids to chew after brushing, the color would stick to anything left so you can evaluate how well she really IS brushing.  ask about them!

Answer 6

she's not brushing her teeth very well. get her an electric toothbrush and see the dentist right away.
