Hello.

We are Seoul Dia Dental Clinic in Magok-dong, where we do not make dental topics too difficult and explain only the essentials clearly.

These days, if you search Naver, keywords like ‘gum regeneration PDRN’ and ‘gum salmon injection’ have become much more common.

In dermatology, many people have at least heard of salmon injections once, but now a lot of people are asking, “Wait... is this good for the gums too?”

So today, we’ll explain very simply what PDRN actually is, why it has become such a popular search term, and what the relationship is between salmon injections and gum regeneration.

PDRN? Salmon injection?

PDRN, put simply, is a regenerative ingredient that helps the body recover on its own.

To explain it a little more clearly, it acts like a switch that says to wounded areas, weakened tissue, or parts that are recovering slowly, “Let’s try to regain strength here.”

But this leads to a question many people ask: “Then why is it called a salmon injection?” The reason is the source of the ingredient.

PDRN (PolyDeoxyRiboNucleotide) is a regenerative substance made by carefully purifying very small DNA components obtained from salmon.

This ingredient is similar to the structure of human body cells, so the body does not recognize it as a foreign substance and naturally accepts it.

Because of that, when it is used on wounds or weakened tissue, it can help gently stimulate the recovery response.

That is why, in dermatology, it has long been widely used for

  • skin regeneration
  • wound recovery
  • elasticity improvement

and because it uses an ingredient derived from salmon, people commonly call it a “salmon injection.”

In short, this is the summary. A salmon injection = an injection using PDRN ingredients. Whether it is used on the skin or the gums, the key point is that it is an ingredient that helps tissue recovery.

What do salmon injections have to do with gum regeneration?

Salmon injections and gum regeneration! Surprisingly, they are very closely related. The gums also need good blood flow, are vulnerable to inflammation, and are a tissue where recovery is important.

When there is periodontitis, or when gum inflammation keeps recurring, the gums gradually become thinner and weaker.

At this time, PDRN plays the following role. It helps circulation, stimulates the recovery response, and creates an environment in which the gums can improve again.

In other words, the same principle used in salmon injections for the skin is applied to the gums as well.

That is why, these days, PDRN is increasingly being used for purposes such as

  • recovery care after gum treatment
  • early-stage weakened gums
  • gum condition management before implants

Gum regeneration injection? Does the gum grow back? Let’s clarify this accurately

This part needs to be clearly explained. To be honest, if you get a gum regeneration injection, does lost gum tissue grow back as new?

That is not true.

The accurate wording is that it helps weakened gums recover and helps lift a condition that has been damaged by inflammation.

PDRN is not a treatment that creates new gums, but rather a treatment that supports the gums’ own ability to recover.

One important point here. There is no treatment that is “good for everyone.” It only has meaning when used according to the condition of the gums.

A quick summary of today’s content

  1. PDRN is a regenerative ingredient that helps tissue recovery
  2. Salmon injections and gum regeneration work on the same principle
  3. The expression “the gums grow back” is an exaggeration
  4. The accurate meaning is a treatment that helps gum recovery
  5. It should be used appropriately for the condition in order to expect results

In gum regeneration treatment, diagnosis and judgment are more important than information.
