In our daily clinical practice, almost every patient asks questions about how dentures are cared for and how long they last. The following is an example of an automobile to illustrate this point. In some ways, dentures and automobiles are very similar: both can significantly improve the quality of life. In the “food, clothing, housing and transportation”, the car improves the “line”, and denture improves the “food”, “good teeth, appetite is good, eat all good! Good teeth, good appetite, good food”. In today’s era where food is popular and foodies are all over the place, the importance of food is self-evident. In addition, denture can improve the beauty of one’s face, improve one’s self-confidence, and is also very helpful to one’s career success. II Both require careful care and maintenance. We need to spend a large amount of money every year to go to a 4S store to maintain and care for our cars in order to keep them in a good condition, prevent accidents and prolong the life of the car. The same is true for dentures. In addition to using them in daily life according to doctor’s instructions and maintaining them carefully, we also need to find a doctor to review them regularly and deal with any problems in time, which is very important for prolonging the lifespan of dentures. Unfortunately, most of the current veneer patients do not do this, denture is not a problem is never looking for the doctor. Three Both have an expiration date. When the lifespan is up, the car has to be scrapped, no matter how expensive the car is. The same is true of dentures. Many patients think that after spending so much money on dentures, they should use them for the rest of their lives. There is always a gap between the ideal and the reality. Often dentists will tell you that dentures have an expiration date, and that they must be replaced and redone when they become ineffective or have problems. However, dentures and cars are also different. A car is an industrialized product that can be produced in large quantities from a single mold. Teeth and mouth is an organ of the body, oral diseases and missing teeth is a disease in the human body, dental veneers is also a medical act that needs to be completed by the doctor, each patient’s missing teeth will not be exactly the same, there are many variations, so dental veneers or to find a qualified specialist to complete.
