I recently noticed a brown line on my dental implant. I had an appointment for a cleaning and it totally slipped my mind to ask my dentist about it. After the cleaning, the dark line was gone so I just assumed it must have been a stain so I stopped worrying about it. Then I noticed today the line is back, so now I am wondering if something is wrong. If it’s nothing, I don’t want my dentist to think I am paranoid, but why would it show up in the exact same place if it was a stain? — Mary Ann in Oklahoma
Mary Ann,
It’s highly possible that what you are seeing is a stain. Sometimes porcelain crowns can have slight defects, or they can get a very small crack in them. If there is an indentation or crevice, it can easily collect and show a stain. It’s very possible that your hygienist removed the stain, but it has come back again.
You should probably see your dentist soon to determine if it is a crack because there is a risk that it could give way and completely shatter the crown. Unfortunately your dentist will not be able to predict if or when that could happen. If the defect shallow, you may be able to remove the stain by brushing the area a little more thoroughly or it may be possible to buff the spot, which will smooth it out so it doesn’t collect stain. I also could be possible that you will eventually have to have a new crown made. The good news is that you won’t have to have the entire implant redone, just the restoration that attaches to your implant.
