InstaMorph Reusable Moldable Plastic | Thermoplastic Beads, Meltable Polymorph Pellets | Lightweight Modeling Compound for DIY Crafts, Sculpting, Cosplay Accessories | Temporarily Repair | White, 3oz

I was clued into this product by a Youtube video demonstrating how to make a retainer out of this stuff. Unlike most people looking to make retainers, I still have my original upper and lower Hawley retainers from 20+ years ago, and yes I still wear them every night, and yes my teeth still look great!! I've had new dentists stare at me like I'm a rainbow-colored unicorn sitting in their chair. I was interested in getting a second set of retainers for short-term travel purposes, so I wouldn't have to move my original retainers from container to container, possibly forget to pack them, and there's always the risk losing them. My original orthodontist has retired by now, so I looked into how much it would cost to get a second set from an unaffiliated dentist/orthodontist and found I was not willing to shell out hundreds of dollars for something that would mostly sit idle except for a couple days' worth of travel a year. Enter this InstaMorph plastic. I wasn't sure whether to get the 3oz or 6oz size, and eventually chose the smaller one. Turns out 3 ounces was more than enough. I made my retainers quite thin for comfort, but I also have tons of beads left, even after accidentally wasting the first small spoonful by putting it into water that wasn't hot enough. You'll know the water isn't hot enough if the beads don't turn from opaque white to clear. If they stay opaque, they don't bunch up together, and instead stay loose and unusable. What I should have done at that point was add more, hotter water to get them to turn clear and bunch up together, but I wasn't thinking at the time and just dumped the whole mixture into the trash, Luckily, I had plenty of the stuff left to try again. My next attempt was successful, as with hot enough water, the beads turned clear and bunched up together such that I could scoop them out of the water in one piece and start to mold them. I basically rolled them into a log shape, then used a small plastic rolling pin to flatten the log out into a really thin rectangular piece, and then tried to mold the piece to my teeth. This took a long time and a ton of trial and error, and I was constantly refilling hot water and re-dunking the piece to get it more pliable again so I could roll it out even thinner, shape it to my teeth better, or cut off excess with scissors (it's way easier to get smooth cuts when semi-pliable than when hardened). Creating the upper retainer was a huge chore. The lower retainer went way quicker and easier, but I'm not sure if that's because I created the upper one first, because I wasn't fighting gravity, or some combination of both. In the end, I now have an extra set of retainers for those rare travel days, it only cost me about $10, and despite how long and how much effort it took, I am very pleased with how they turned out. There is some pliability in the plastic since I made them so thin, but that makes them more comfortable and I can tell they are plenty rigid enough still to hold my teeth in place overnight. Very happy with my purchase, and wondering what other nifty uses I can put the remaining beads to.

I have a crown that broke off one of my teeth and I lost it and had to wait quite awhile before I could get in to get another one put on and it was noticeable if I smiled in any way. I was looking for a temp solution to get me by and these worked well. Just toss some into hot water and they turn clear when they are ready so if they don’t then water is not hot enough. Once they are clear just pour water out and start molding a small amount to resemble a tooth. Before it hardens which will be quick mold it into the space it needs to fit to get a better measurement and then smooth out a little more and quickly make the adjustments needed. I put back in and let it harden and cure and it always could still pop back out but was snug enough it would stay in place for the day. Works well when you need a important temp solution.

I have ordered this product several times before but this last time, the product is different. Doesn't melt down soft like it did before. Whatever changed needs to go back. Feels too rubbery and doesn't allow time to be worked into shape.

Saw this stuff on tik tok,ppl using it for their teeth. My cap fell out so I tried twice to wedge it in but I couldn't get it smoothed out enough, n the more u mess with it the harder it gets feels like rubber. It did harden with the cold water and turn white but never got harder than a hard rubber type substance. Maybe I did something wrong,idk. Will try again later

These are so convenient. I’m still using these from months ago.
