What Are Procaine Shots?

Procaine is a local anesthetic drug used in dental procedures. A local anesthetic is a medication administered on a patient to numb a specific part of the body.

Can procaine shots really cause nerve damage?

Procaine causes numbness in the skin and mucous membranes. And, because the area where Procaine is administered will be numb, you must proceed with extreme care to prevent severe injuries to the area during and after the procedure.

Consultation with your doctor is also required for pregnant or breastfeeding women who wish to use Procaine in surgery.

In addition, inform your doctor if you are taking any other medications, as these may have adverse or unknown effects when combined with Procaine.

How does it work

Procaine is a local anesthetic drug used to target nerves to block them from sending pain signals to your body and brain.

It is commonly used in dental procedures, particularly around the teeth and gums. The numbing of the area is necessary to work on the teeth effectively and for the patient not to feel anything during any dental procedure.

Uses and Effectiveness

Procaine is an effective pain reduction during surgeries and treatments.

Similar to other anesthesia, procaine also acts as a vasoconstrictor. Vasoconstriction literally means narrowing of the blood vessels. It is used to help reduce the bleeding and heightens the effectiveness of the drug administered.

Procaine shots are more appropriate on major dental procedures like root canal because it involves affecting the gums and nerves, which can be painful.

Risks and Adverse Effects

As with any medical procedure, there’s a potential risk of complication; however, these complications are infrequent. Complications will also depend on various factors, like your medical history and your activities (smoking, usage of illicit drugs, etc.).

Your dental provider will brief you on possible risks and complications before you decide to undergo any procedure. In most cases, the benefit outweighs the risks.

The difficulty of breathing and swelling parts of your face and mouth are some of the common side effects of procaine. Procaine can also cause chest pains, irregular heartbeats, vomiting, and seizures.

It is estimated that one out of every 10,000 individuals who receive anesthesia will have an anaphylactic reaction to the medication. Allergic reactions can occur due to a variety of circumstances other than the anesthesia itself.

Although some allergic reactions can be severe, it is essential to discuss with your dentist or specialist an effective treatment plan.

The application of procaine can also lead to the depression of neuronal activity. It can also damage the nerves which run between the spinal cord and the rest of the body, causing paralysis or the inability of a person to move a part or parts of their body.

A very rare effect of the drug is death, as around one person may die in every 100,000 anesthetics given.

So, to cast your fears away, telling your complication history to your dental practitioner will help on how the local anesthetic will be administered.


Procaine shots as dental anesthetics are a standard, safe, and effective procedure.
