Had mine pierced 11 years ago! It hurt for quite a few days, you need to keep your mouth clean, salt water is a good idea especially after eating anything!
No talking for about 3-4 days, at all!! Trust me it will help recovery! And no kissing, oral sex at all for 2 weeks, or you can get infected, the human mouth has more bacteria in it than a dogs!! But dont kiss ur dog either xx
My husband had his done b4 i met him too, 11 yrs ago, and we r still happily pierced. Look after it now, and it will stay for years.
Mine had come undone a few times, but i never have swallowed it, make sure its done up properly at least once a week to avoid mishaps. good luck xx
