Expert answer:
The greatest care you should take after putting on a piercing is adequate local hygiene.
On the skin, wash with water and soap every day. In the mouth area, brush your teeth often (4 times a day), especially after meals. You do not need to use other special products.
People who have piercing may have skin infections or dental problems in cases of piercings on the tongue or lips. They can also develop local scar as keloids, depending on the familiar predisposition and location of the piercing (more occurs in the ear). Certain situations need surgical correction.
In case of doubt, seek the general practitioner or family doctor.
