Even the kindest, hardest-working people can tell white lies sometimes. These little untruths can be relatively harmless, such as eating food you don’t particularly like to please the loved one who cooked it. Others, however, can have devastating impacts on you and/or others. Fortunately, when it comes to crimes, physical evidence can establish facts and substantiate or refute what people claim as truth. In dentistry, your mouth leaves some evidence behind, which means if you try to lie at your dental checkup, your dentist will know something isn’t right.
