For a few years now, I've had recurring black tooth stains. I am unable to identify the cause of the issue. I don't take any iron supplements. I don’t drink or smoke. There are no issues with the water I drink, and I consume a very typical diet of vegetables, meat, and rice. I typically have one or two cups of coffee or tea per day. which I thought would be the issue. However, I stopped consuming coffee and tea for several months after professional cleaning. This did not cause the stain to change.
Additionally , I have acne, memory fog, fatigue and severe hair loss. So, I had an iron test done to see if I have low iron and the results were normal.
The test was done without fasting. Can it have an influence on the result?
Can someone please interpret the result?
