[ Magok Station Dental Clinic_01 ] Why Do I Need Dental Anesthesia? The Role and Principles of Anesthesia

Hello.

We are Seoul Dia Dental Clinic, responsible for healthy smiles at Magok Station.

When receiving dental treatment, it is often necessary to administer anesthesia first before beginning the procedure.

This is to prepare for treatments that may cause pain.

Ironically, some people sometimes experience additional pain because of the anesthesia itself.

That is why some people ask:

"Do I really need anesthesia...?"

For those of you who have wondered about this, Seoul Dia Dental Clinic will explain the need for local anesthesia, as well as its types and characteristics, in an easy-to-understand way.

Simply understanding it properly can often make the experience much less frightening than expected.

Why Is Dental Anesthesia Necessary?

It may seem like an obvious question, but not many people know the answer precisely.

Dental treatment directly involves the teeth and gums.

Because nerves and blood vessels are densely distributed around the teeth, treatment without anesthesia can cause severe pain.

The role of anesthesia is simple: to block pain during treatment so that patients can receive treatment comfortably.

Thanks to anesthesia, patients can receive treatment without pain, and dentists can proceed accurately and with concentration.

How Does Dental Anesthesia Work?

The type of anesthesia primarily used in dentistry is local anesthesia.

Unlike general anesthesia, which causes you to lose consciousness, local anesthesia involves injecting an anesthetic only into the nerves around the treatment area to temporarily block pain signals from that area.

When the anesthetic acts on the nerves, they can no longer transmit pain signals to the brain.

Therefore, during treatment, you may still feel the sensation of an instrument touching the area or a sense of pressure, but you will not feel pain.

What Ingredients Are in Anesthetic?

The anesthetic most commonly used in dentistry is lidocaine (Lidocaine).

Lidocaine is an ingredient with a well-established safety record that has been used since the 1940s.

In addition to lidocaine, dental anesthetics often contain a small amount of epinephrine (Epinephrine).

Epinephrine constricts blood vessels and prevents the anesthetic from being absorbed too quickly, helping the anesthetic effect last longer.

However, people with cardiovascular disease or high blood pressure may need an adjusted anesthetic concentration, so be sure to inform your dentist before treatment.

How Long Does the Anesthetic Effect Last?

The duration of anesthesia varies depending on the type and amount of anesthetic used, as well as individual factors, but it generally lasts about 1–3 hours.

In the case of nerve-block anesthesia used for lower-jaw treatment, the effect may last even longer.

While the anesthesia is wearing off, it is natural for your lips or tongue to feel numb or tingling.

During this time, it is best to avoid hot food and drinks and be careful not to bite your cheek or tongue.

What Was It Like Before Anesthesia Existed?

Let’s take a brief look at the history. Haha.

(Is this a bit out of the blue? ^^)

Before dental anesthetics were developed, treatment was performed without anesthesia.

Naturally, this involved severe pain, and dentistry inevitably became recognized as something to fear.

Modern dental anesthesia began to be used in earnest starting in the late 19th century.

Since then, anesthesia technology has continued to develop, and today it is possible to achieve sufficient anesthesia with a much smaller amount.

The fact that dentistry came to have a frightening image is also believed to be significantly influenced by memories from the time before anesthesia that were passed down through generations.

Does an Anesthetic Injection Really Hurt?

Let me be honest.

I cannot say that it does not hurt at all.

However, many people say it hurts much less than they expected.

To reduce the pain of an anesthetic injection, a topical anesthetic ointment can be applied first.

Because the surface of the gums is numbed in advance before the injection, the pain from the injection itself can be greatly reduced.

Pain is also reduced when the anesthetic solution is injected slowly, and in some cases, a pain-free anesthesia device is used for this purpose.

Topical anesthesia and pain-free anesthesia devices will be covered in more detail in the next post.
