The teeth that appears once in a life are known as Monophyodont. Eg- Pre molars, Last molars(Wisdom teeth) . And those that appears twice are diphyodont. Eg- Incisors, Cannines and Molars. Our teeth is embedded in jaw, hence known as the coconut. There are different types of teeth, which is known to be heterodont.
