Browish-Black Lines Between Teeth?

Hi, I am 24 and haven't been to a dentist in probably 4 or 5 years because I did not have dental insurance. Now I do have insurance, and I have an appointment to see a dentist in a few weeks. I have always tried to take care of my teeth (brushing, flossing daily and occasionally using listerine), and they have always been healthy. I have never had a cavity in my life.
During this past July, I noticed some blackish-brownish lines in between a couple of my teeth. Now this month, they are in between almost all of my teeth. Some of the new lines are more of a tan color. At first, I was panicking about cavities. But now, I am questioning whether or not they are cavities because I seems like the lines appeared too suddenly to be cavities or can cavities do that? What could this be? Also, when I see a dentist, is whatever it is reversible?

Brushing with a toothpaste that contains Stanous Flouride can also cause dark staining of teeth on some individuals.

I just switched to Sensodyne toothpaste because of all the cavities i'm having filled and my teeth are really sensitive now. Just noticed that the dark lines in my teeth have happened since switching but thought they were from having cavities filled.

i have these stains on a couple if my terth but dont have enough enamsl to endure whitening. is this something that can be scrubbed off during a 6 month checkup? i am also noticing i the same areas sharp little places, sometimes with miniscule holes i can only feel woth my tongue, on these teeth. theyre the ones on the bityom a few from the back that almost look like they could be two tereth fused together. the sharpness with little cracks and the blackness in the crevaces out of nowhere is quite alarming....

My son has this and I am trying to figure it out as well.  It started about 2 months ago.  He is 23.  He had braces and the came off about 6 months ago.  All fine until now.  Now, gray between all teeth.  Cleaning removes it temporarily but it comes back within a week or two.
Please post any info you find and I will do the same.

Hi, thanks for the replies. I do not smoke or drink coffee. However, I do drink tea occasionally so maybe that's what did it. But could it be the tea because I have been drinking tea since I was a kid and these stains are just now showing up?

Most likely it is stain. Smoking is one of the main factors for this typical stain. Dont panic, If you regularly floss i doubt your oral hygiene is that bad to cause multiple cavities of this type. You will need to require a prophylaxis session. It will only take 5 min to remove that stain. Sometimes the stain could be intrinsic embedded in your teeth structure. In that case you will have to get a teeth whitening treatment done.
Faq's section here http://*********.**/faqs will answer your questions about teeth whitening solutions on intrinsic and extrinsic stains. I believe its the last question.
Good luck

Hello,
I just noticed your post while looking for some dental info. I did the same thing as you (4-5 years) and so have many others so don't feel too bad. The important thing is to take care of it now.
I'm not a dentist, but my guess is the lines are stains from food, drink or smoking. I don't smoke but I do drink a fair amount of coffee and tea. I have my teeth cleaned three times per year now and floss and use "go between" brushes faithfully. In spite of this I still get a little staining that they have to scrape off. The thing about stains is that the more time passes by, the faster they seem to accumulate. You want to get rid of the staining because they encourage tartar development.
I hope your appointment goes well.
