Can anybody please tell me what year false teeth as we know them were invented?

the modern kind that look natural,as opposed to wooden ones which i am told have been around for centuries! reason i ask is on %26quot;have i got news for you%26quot; last night it said that walt disney had some wooden ones! + i wondered why a guy who that rich would have them! as it was only in the 1950,s surely they had dentures before then? i could be wrong!

Can anybody please tell me what year false teeth as we know them were invented?
The first porcelain dentures were made around 1770 by Alexis Duchâteau. In 1791 the first British patent was granted to Nicholas Dubois De Chemant, previously assistant to Duchateau, for De Chemant%26#039;s Specification, %26quot;a composition for the purpose of making of artificial teeth either single double or in rows or in complete sets and also springs for fastening or affixing the same in a more easy and effectual manner than any hitherto discovered which said teeth may be made of any shade or colour, which they will retain for any length of time and will consequently more prefectly resemble the natural teeth.%26quot; He began selling his wares in 1792 with most of his porcelain paste supplied by Wedgwood. Single teeth in porcelain were made since 1808. Later dentures were made of vulcanite and then, in the 20th century, acrylic resin and other plastics. In Britain in 1968 79% of those aged 65-74 had no natural teeth, by 1998 this proportion had fallen to 36%.

Reply:Good and accurate information above, but...





The natural looking acrylic denture bases that we take for granted today were not introduced until the 1930%26#039;s. Prior to that, the %26quot;best%26quot; we had were made of pink vulcanized rubber. This discolored greatly and did not adhere to the denture teeth, so it easily developed dark stain lines between the denture base and the teeth.





Acrylic denture teeth came along somewhat later, but I do not know the exact date. I%26#039;d guess that it was in the late 1930%26#039;s or early 1940%26#039;s. These teeth were not all that great, so dentists still used porcelain teeth on acrylic denture bases for the %26quot;premium%26quot; dentures.





The most popular high quality denture teeth in use today are a composite resin material (from a few different manufacturers) that was introduced for denture teeth in the 1980%26#039;s, believe it or not.





From that perspective, I would say that %26quot;modern%26quot; dentures were not made until the introduction of processed denture resin for the base material in the 1930%26#039;s.





I%26#039;d bet Walt Disney had vulcanized rubber base dentures. They did indeed look horrible after a couple of years in the mouth, but I%26#039;d be surprised if he had wooden teeth.
