Black line stain  
I just submitted a question about my 19 year old's black line stain and I realized too late that I could attach a photo so I'm am sending a photo of his stain now.
Thank you.

Hi Darlene,
there is no problem here.

For your son the black line at his gum line is normal
It does not look good but it is not unhealthy.
It can be removed if it looks bad with a little powder abrasive cleaner that you would use on a sink or on dishes (eg. AJAX). Place it on a piece of gauze and rub gently, rinse out don't swallow.
Only clean the area's that show when he smiles.

The stain comes from mineral in the saliva and is seen mostly in people who never ever  get cavities.

Eventually your son will outgrow this minor aesthetic problem.

All the best,
Dr. Moss
