I have a small black line on my molar, and it shows no signs of pain or sensitivity. What is it? What do I do?
Can the black line lead to more serious dental problems if left untreated?
Yes, if the black line is caused by decay, it can lead to further damage, such as tooth pain, infection, and even tooth loss. It's best to have it checked by a dentist.
