The gap between your tooth and gum, often appearing as a "black triangle," is most likely due to receding gums.
Receding Gums: The Primary Cause
According to the reference material, gum recession is a key reason for these gaps. Here's a breakdown:
- Gum Disease: Conditions like gum disease can cause your gums to become thinner and pull back (recede).
- Loss of Gum Tissue: As your gums recede, they no longer fill the natural spaces between your teeth.
- Appearance of Gaps: This receding action leaves empty areas that appear as dark triangles between your teeth and gum line.
In summary, if you notice a gap between your tooth and gum, gum recession (often caused by gum disease) is the most probable reason.
