Creating a tooth moldable plastic is a useful skill for those who want to create a temporary tooth or a model of teeth. This skill can be especially useful for those who cannot afford dental treatments. The process involves heating non-toxic and biodegradable plastic pellets, which can be done in the microwave, and then placing them into a mouthguard or teeth tray to create an imprint of your teeth. The plastic can also be reformed and refined if mistakes are made.

What You'll Learn
Soften non-toxic, biodegradable plastic pellets
To create a tooth-moldable plastic, you can use non-toxic and biodegradable plastic pellets that can be softened with hot water and moulded with your hands or tools. These pellets are made from renewable raw materials such as vegetable fats and oils, corn starch, straw, woodchips, and recycled food waste. They are designed to degrade quickly and safely, leaving no toxic residue.
To soften the pellets, you can follow these steps:
- Boil a pot of water on the stove.
- Place the desired amount of pellets into the hot water. The plastic will become soft and clear.
- Remove the softened pellets from the water. You will have several minutes to shape the plastic before it starts to stiffen.
- If you need more time to work with the plastic, you can dip it back into the hot water to soften it further, or use a heat gun or hair dryer to target specific areas that need softening.
- If you are satisfied with your mould, you can speed up the hardening process by dipping it into cold water.
It is important to note that this type of plastic is not liquid enough to pour into a mould, so you will need to press it into your desired shape. You can make your own moulds using silicone mould putty or buy ready-made moulds. Before placing the plastic into a mould, coat it lightly with vegetable spray or a mould-release spray to ensure easy removal.
Additionally, you can add colour to your plastic by mixing in colour pellets while it is still hot, or by painting it after it has cooled. The plastic can be cut, filed, drilled, and sanded once hardened, and it can be remelted and remoulded if you are not satisfied with your initial result.

Heat pellets in water
To create a tooth-moldable plastic, you can use thermoplastic beads or pellets, which are easy to use and can be purchased online. To mould these pellets to your teeth, you will need to heat them in water.
Firstly, fill a pot with water and place it on the stove to boil. Ensure you have a sufficient amount of water in the pot, as you will need to submerge the pellets in the water. Once the water has reached a temperature above 150°F, you can add the pellets.
Add the thermoplastic pellets to the hot water. With a temperature of over 150°F, the pellets will melt within minutes. Stir the pellets occasionally as they heat up to ensure they melt evenly. You can use a spoon or a similar utensil to stir, but be careful to avoid splashing hot water or molten plastic.
Once the pellets have completely melted, remove the pot from the heat. Do not turn off the stove yet, as you may need to reheat the plastic if it starts to solidify. The plastic should be pliable and easy to work with at this stage. If it becomes too cool and solidifies, simply return the pot to the stove and reheat gently.
Now that your plastic is molten, you can begin the moulding process. Carefully remove the pot from the stove and set it on a heat-resistant surface. Dip a mouth guard or a similar object into the molten plastic, ensuring it is fully coated. Leave the coated mouth guard to cool slightly, then run it under cold water for a few seconds to prevent any surface burns.
With the plastic softened and cooled slightly, it is now safe to place it in your mouth. Bite down hard on the mouth guard to leave an imprint of your teeth. Run it under cold water again to fully set the imprint.

Bite down to imprint teeth
To create a tooth-shaped mould, you will need to prepare a mouth guard, a pot of boiling water, a mould release spray, plaster and a Popsicle stick.
Firstly, fill a pot with water and boil it on the stove. Then, dip the mouth guard into the water for about a minute until the plastic becomes soft. Remove the mouth guard from the pot and place it under cold running water for a few seconds to cool the surface so that it doesn't burn your mouth.
Now, you can insert the mouth guard into your mouth and bite down hard to leave an imprint of your teeth in the plastic. Take the mouth guard out of your mouth and run it under cold water again to set the imprint. Once the mould is set, spray it with a mould-release spray to prevent the plaster from sticking to the mould when drying.
Mix the plaster according to the manufacturer's instructions and scoop it into the mouth guard mould. Use a Popsicle stick to level the top of the plaster. Leave the plaster to dry for about an hour until it is hard to the touch.

Use plaster to fill mould
To create a tooth-shaped mould, you will first need to create an imprint of your teeth. One way to do this is by using a mouth guard. Boil water in a pot, dip the mouth guard into the water for one minute to soften it, then run it under cold water for a few seconds so you don't burn yourself. Bite down hard on the mouth guard to leave an imprint of your teeth, then run it under cold water again to set the imprint.
Now that you have an imprint of your teeth, you can use this as a mould to create your tooth-shaped mould. Before pouring in the plaster, coat the inside of the mouth guard mould with a non-stick substance, such as soap or a mould-release spray, to ensure that the plaster doesn't stick and can be easily removed.
Prepare your plaster according to the manufacturer's instructions. The consistency of the plaster should be similar to that of heavy whipped cream. Be mindful of the setting time of the plaster, as once it starts to set, you won't be able to stop the process.
Pour the plaster slowly and carefully into your mould. Start pouring at the edge, letting the plaster gradually fill the space. Avoid pouring directly onto the model to minimise the formation of air bubbles, which can distort the final shape. Tap the mould on a hard surface to help remove any trapped air bubbles, and use a tool such as a paintbrush or pencil to smooth out the plaster and eliminate any remaining bubbles.
Once the plaster has been poured, use a Popsicle stick to level the top of the mould. If your mould has an artificial tube, such as a straw, to create an opening for pouring, make sure to fill it with plaster as well.
Leave the plaster to dry completely. Depending on the type of plaster, this could take about an hour or so. Once it's hard to the touch, you can remove the plaster cast from the mould. Congratulations, you've now created a tooth-shaped mould using plaster!

Reform if mistakes are made
Reforming tooth-mouldable plastic after making mistakes is possible, especially with thermoplastic beads. These beads are designed to be reheated and remoulded, allowing users to start their projects anew or fix any errors. This involves simply reheating the plastic to return it to a mouldable state.
However, it is important to note that the reforming process may vary depending on the type of plastic used and the specific product. Some plastics may require specific temperatures or methods for reheating, such as boiling water or a specific degree Fahrenheit. Therefore, it is essential to follow the instructions provided by the manufacturer of the specific product you are using.
Additionally, it is worth mentioning that tooth-mouldable plastics are not solely intended for cosmetic purposes, such as cosplay or Halloween costumes. They can also serve a practical purpose by filling in gaps between teeth, correcting misaligned teeth, and preventing teeth from shifting due to missing neighbours. As such, extra care should be taken when reforming tooth-mouldable plastic to ensure it still serves its purpose effectively.
Furthermore, while tooth-mouldable plastic can be reformed, it is important to be cautious about the potential risks associated with DIY dental procedures. These products may pose choking hazards, create "food traps" leading to tooth decay and bad breath, and cause discolouration when exposed to certain foods and drinks. Therefore, it is advisable to consult a dental professional or seek advice from reputable manufacturers or sources to ensure safe usage and avoid potential health complications.
Overall, the ability to reform tooth-mouldable plastic provides users with the opportunity to correct mistakes and achieve their desired results. However, caution should be exercised to ensure the process is safe and does not compromise oral health.
