How to make false teeth

Wearing rubber gloves on I start dripping a little acrylic fluid into the mould and slush it around. Always work under forced ventilation and keep gloves on the whole time as this can be hazardous to your health .tandgjut23.JPG (10842 bytes)

 I start with a little transparent powder and continue with a light tooth shade. Then I continue with a little more yellow and last a quite dark one. This is for making the teeth seem like they have a natural shade. Unfortunately it is very hard to get it right the first time, only experience will help you here. .
When the correct amount of acrylic mixture is in the mould.
I gently reposition the plaster teeth into the mould.
It is very important to make it fit as snugly as it did when you made the mould.
Putting it back incorrectly will make the teeth to become too thick or get air bubbles.

Place the moulds into a pressure cooker (3 bar) with hot water for final hardening.tandgjut27.JPG (16958 bytes)

If you don't have a pressure cooker you will have to wait maybe 30-45 minutes.
Hopefully you now can separate the moulds and take out a good cast.
Sometimes you can make a second casting but often the plaster teeth becomes bad.
