The most common cause of a dent in the nose would be from trauma to the nasal bone that has been missed or forgotten. Sometimes, with age, the dent becomes more obvious as the traumatised part does not grow normally. If the dent has been there since birth, it could be a congenital dent, where one small part of the nose structure did not develop as well.
Usually, after an examination to determine where the dent actually is, I do a simple nasal scope too in clinic to see if the internal nasal structures are also affected. Rarely, a CT scan of the nose is needed.
Most nasal dents can be corrected nowadays if you choose to, but it would be important to correct that after a good understanding of which structures are affected, and to balance the cosmetic and functional aspects of the nose.
