A tongue piercing is absolutely known to cause tooth problems (such as damage to the enamel of the teeth & breakage of the teeth) & other oral problems. It can increase the risk for endocarditis (which is an infection within the heart and blood vessels), especially in a person who has an abnormality within the heart to begin with. Poor dental hygiene is also associated with heart trouble later on, whether you have a tongue piercing or not.
In every person's mouth there are many bacteria, which can cause bad breath & tooth decay. When you get your tongue pierced, you give the bacteria a way to get into your bloodstream, particularly when the tongue is healing from the piercing. They can then travel directly to the heart & set up an infection.
Hope this helps! Overall, I would pierce (or not!) another, less risky part of my body!
