Can You Eat Super Glue? What Happens if You Do?

Children, and even adults, are often curious about what glue tastes like, and at some point, they will try to eat it. This might be safe with small amounts of PVA glue as it’s non-toxic, however, it is not the same with high-strength types of glue such as super glue.

So, can you eat super glue? You can’t eat super glue because it contains cyanoacrylate which is a toxic chemical that can cause serious harm when ingested. This kind of glue bonds quickly when it comes in contact with moisture so it might get stuck to the inside of your mouth. If you swallow the superglue, it will cause a blockage in your digestive tract leading to severe abdominal pain, nausea, and vomiting.

What Is Super Glue?

Super Glue, also known as Crazy Glue, is a kind of glue that contains a chemical compound called cyanoacrylate. This chemical gives the glue the ability to form bonds quickly and strongly with various kinds of surfaces including metal, stone, ceramics, foam, plastic, and even glass.

How Does Super Glue Work?

Super Glue is different from traditional water-based adhesives. That is because the main ingredient in Super Glue is cyanoacrylate which is an acrylic monomer that transforms to a plastic-like form when it dries ensuring a strong long-lasting bond with any surface it’s used on.

It’s also different from other adhesives because it requires special bonding conditions to be completely effective. Basically, super glue will not bond with a surface unless there’s moisture present. So, if you try to use it on a completely dry surface, it will not be effective or form any bond with that surface.

In the presence of moisture, the molecules in the glue will react very quickly and form tight chains between the two surfaces you’re trying to stick together.

Is Super Glue Toxic?

Super Glue is considered a toxic adhesive as it contains many harmful chemicals such as cyanoacrylate, ethanol, xylene, N-hexane, toluene, and light aliphatic naphtha.

These chemicals can cause serious health issues if they’re inhaled or ingested. The glue can also cause severe irritation or infection if it comes in contact with your bare skin or eyes.

What Happens If You Eat Super Glue?

If you eat Super Glue, you will experience some problematic symptoms. The severity of these symptoms will depend mainly on the amount of glue you ingested.

Once the super glue gets inside your mouth, it will quickly start to bond and harden due to the presence of moisture.

If it’s only a small amount of glue, there’s a chance that you will not swallow it and it will remain stuck to your teeth or the inside of your mouth.

However, if it’s a large amount of glue, you’re more likely to accidentally swallow it which means it will bond and harden while it’s in your digestive tract. This can lead to the possibility of gluing the walls of your intestines together causing a blockage as well as severe abdominal pain, nausea, and vomiting.

What to Do If You Get Super Glue in Your Mouth?

If you get super glue into your mouth, try to immediately spit it out before it starts to bond. Do not try to rinse your mouth with water as this will only accelerate the bonding process.

If the glue is already bonded and stuck to the inside of your mouth cavity, tongue, or teeth try eating peanut butter or drinking some vinegar to soften the glue before spitting it out.  Try not to swallow any amount of glue as much as possible to avoid causing more damage.

If the glue remains stuck to the inside of your mouth cavity or if you accidentally swallow some of it, it’s highly recommended to seek professional medical or dental attention.

Why Do People Eat Glue?

People, children or adults, mostly eat glue out of boredom or curiosity not realizing it could make them sick. Since many types of glue are labeled as “non-toxic”, it might seem safe to try to get a taste.

However, “non-toxic” doesn’t always mean edible or food-safe. It’s generally advised not to eat any type of glue because it’s not made to be eaten, it doesn’t taste good, and it doesn’t provide any kind of nutritional value.

So, glue should not be consumed or used in any way other than what it was intended for as an adhesive.
