Unlike tattooing, piercing isn't permanent. Removing jewelry is a lot easier and less painful than lasering off a layer of your skin.
Whether you want to temporarily take off the jewelry for an event or let your piercing close up completely, do so with caution. If at all possible, go back to the piercing parlor to have it removed by a professional. If you do the job yourself, make sure both your hands and the pierced area are squeaky clean. Be slow and steady. Follow the cleansing ritual you went through when you first got pierced.
Remember, just like with an earring, you'll have a tiny little mark or bump where the hole used to be. This is the price you pay for experimentation.
