It is recommended to have your daith piercing jewellery changed by a professional piercer, especially for the first time. The daith area can be tricky to navigate because it's a more confined space within the ear, and improper handling can lead to complications like infections or delayed healing. Once the piercing is fully healed, which typically takes about 6–9 months, you may be able to change the jewellery at home with proper hygiene and care.
