Are Blue Stitches Dissolvable?

Updated: Jan 29

Blue stitches are NOT dissolvable because they're made of a synthetic material called polypropylene which is a type of plastic that our bodies cannot absorb. In other words they are non-dissolving and non-absorbable which means you will need to have them removed by your doctor.

Blue stitches aren't dissolvable

The blue stitches or rather polypropylene sutures, are made of a synthetic material that does not dissolve. Below is a table of various brands of blue stitches and their dissolvability.

In summary, blue dissolvable stitches do not exist. They are all non-dissolving and non-absorbable, which means they will need to be removed.

In case you had any doubt, we did an unboxing video of blue stitches. We'll read to you the manufacturer instructions so that way you know without a shred of doubt that it is non-absorbable!

Why blue sutures don't dissolve

Blue stitches don't dissolve because they're made of a synthetic material called polypropylene, which is a tough and rigid crystalline thermoplastic. Essentially it is made of plastic!

Do you know what this thermoplastic is commonly used for aside from suturing wounds?

Items made of polypropylene:

  • Bottle caps

  • Plastic bottles

  • Yogurt containers

  • Pallets

  • Food packaging

  • Door trims

From your own personal experience as well as ours, we all know that these plastic items will NOT break down on their own. That means there is a zero percent chance that your body will be able to dissolve it and absorb it.

In fact, these products are not biodegradable nor are they compostable. They're not the most eco-friendly if you know what we mean.

Does the color affect it's dissolvability?

The color of the sutures technically do not affect whether or not they're absorbable or not. Most of the sutures are dyed to be a certain color for ease of identification.

It seems like manufacturers have an agreed upon color scheme for different suture materials and their dye color. We do have a full guide on what the color of dissolvable stitches tend to be as well as the color of non-dissolvable stitches.


If you currently have blue stitches somewhere on your body, they will not dissolve. They are most likely made of a synthetic material called polypropylene which is actually a tough thermoplastic. It is essentially made of the same material as plastic bottles so there is no chance of your body being able to absorb it since they're non-biodegradable.

Ultimately, blue dissolvable stitches do not exist so if you have them, you should give your doctor a call and ask them when your suture removal appointment is. You're going to need them to be removed once they've served their purpose of closing up your wound after whatever surgical procedure you had done.

You may be curious as to whether polypropylene sutures can be used for wisdom teeth and yes they can but dentists often prefer to use dissolvable ones though.

Hello, I'm Dr Chen and I'm an actively practicing dentist in Long Island City, NY. I graduated from Columbia University College of Dental Medicine in 2016 but prior to going to dental school I was already working in the dental field. It's been more than a decade since I first got to know dentistry and let me tell you, time flies by quickly. Since then I've developed a fondness for writing, which is how this all got started!
