Thanks to modern technology, today’s false teeth are almost the same as real teeth. This was not always the case. Originally false teeth were neither comfortable nor durable ( 耐久的). As dentists tried to improve false teeth, they tried many different materials and techniques.
Ivory was one of the earliest materials used to replace lost teeth. These teeth tended to become bad soon and rarely looked natural, but got the job done. Ivory was still used for the base of false teeth, even after quality human teeth became more available near the end of the 18th century.
Human teeth were one of the best materials. The source of these teeth came from dead bodies, poor people looking to make money, and even dentists’ collections. Understandably, these teeth were of poor quality, which meant that they needed to be removed when people were eating.
Porcelain (瓷) false teeth were invented in the late 1700s in France. However, they tended to crack easily, which made them unpopular choices. It wasn’t until after many improvements had been made in the late 1800s that false teeth made of porcelain became a popular choice and replaced previous materials. Porcelain is still a popular choice for many dental applications.
In the mid-1800s, vulcanized rubber (硫化橡胶) was invented and was used to hold false teeth. Because other kinds of false teeth were more expensive, vulcanized rubber false teeth soon became popular.
Luckily for us, new technologies and materials were invented in the 20th century for false teeth. Today’s false teeth are mostly made of plastic or ceramics ( 陶瓷). Plastics are easy to get, so the price of false teeth is also considerably lower. Modern false teeth are more comfortable, easier to chew with, and last longer than teeth made in the past.
