Should I choose metal or ceramic dentures? Choose the right one to make the teeth bright and white for 20 years.

When teeth are dead and dentures must be installed, many people will wonder whether to choose metal materials or ceramic materials, but in fact, everyone's suitable tooth structure is different. Without consulting the doctor, you may have spent a lot of money but changed a tooth that doesn't suit you.

Metal dentures are also classified! When it comes to dentures, many people think of a picture of a "golden tooth" in their mouth. This is an all-metal tooth, but now in order to make the tooth structure more stable and natural, some ceramics will be burned on the metal.

However, Zheng Zhiwen, an attending physician in the Prosthetics Department of Chimei Hospital, said that there is actually a risk in metal materials, that is, "what kind of metal is chosen is very different". For example, inferior metals are easy to corrode, leading to coloring of teeth and gums; Cheaper base metal materials commonly used in nickel may cause allergies and periodontal ulcers, and some base metals are more likely to contain carcinogens such as beryllium.

However, if you choose alloy materials with more precious metals, the price will be more expensive than ceramics. For example, the palladium in them has increased six times in 10 years, so it is actually more expensive to choose "all-metal dentures" for the sake of cheapness.

The benefits of ceramic dentures are only in modern times. The manufacturing method of ceramic dentures has been improved, and "reinforced ceramics", such as zirconia, have been developed to solve the problem that ceramics are easy to crack. Zheng Zhiwen said that ceramics can resist corrosion and are unlikely to cause allergies. In fact, they are more suitable as denture materials, with light transmittance closer to natural teeth and more beautiful colors.

Zheng Zhiwen also said that this practice makes the thickness of dentures thinner, which means that teeth can be ground less and more tooth structures can be preserved. "And now there is digital production, precious metals are generally cast, which is time-consuming and laborious, and it is prone to human error, but all-ceramic dentures will not have such problems. 」

At present, an all-ceramic tooth costs about 20,000 to 25,000 yuan. If it is well maintained, it can be used for 10~20 years. But don't think it's okay to put it on. Dentures still have tooth decay problems. Just clean them carefully, brush your teeth and floss.
