Hi, so let us mark your incisors imaginarily in order to visualize them better. Imagine your lifted incisor is marked 1, and the one to the right of it is marked 2. Now, from your perspective, the incisor 1 (lifted one) is on the left, while the other one is on your right. Now, if a person is in front of you, he would look at your left hand as your right hand right? Similarly, he will look at the incisor 1 on the rught, and thus, he will see the tilted incisor on the right hand side, from his perspective. Hope this helps!
