Hi,
Thank you for posting your query.
Looking at the long duration of the dent, it could most likely be congenital, present since birth. Other possibility could be a trivial
head injury, which could have resulted in the dent.
There is usually no need to worry abut this, however, if you develop pain, or other symptoms, such as giddiness,
vomiting, etc, you may get a
CT scan of the head done for more clarification of the diagnosis.
I hope it helps. Please get back if you require any additional information.
Wishing you good health,
