I started college in 1983, when I was just 20 years old, many people born in the 60’s had already started society or faced with choosing friends at this time, and many of them were looking for remedies because of the unattractive tetracycline teeth, and the most popular one at that time was the light-cured veneers, which were made by grinding away a layer of teeth and filling it with light-cured material, which was indeed whiter than the original teeth at that time. But this whitening makes people look very uncomfortable, very fake, very thick feeling, in exchange for the disadvantage is that the teeth are worn a layer, the front teeth are linked together with a very unnatural feeling, do not do a good job of gum irritation caused by bleeding, will change color over time, very easy to fall off, many patients who have done light-cured veneers may have this feeling, almost can not use the front teeth to eat too hard food, once shedding It is very ugly, there is no choice but to do it again, and then fall off, and then do it again, and again and again, it can be seen that people for beauty is also paid the price, but compared with today’s porcelain teeth, their cost is nothing, because the teeth after the light-cured veneers today can also do a variety of porcelain teeth, and today’s porcelain teeth have no other remedy after the problem, but to remove and redo.
