What Do Dentists Use to Numb: Dental Numbing Shots and Numbing Injections
Dental procedures often involve concerns about pain, especially when injections are part of the process. The idea of getting a numbing shot can leave patients in hesitation or anxiety. First of all, dental anesthetics—specifically local numbing shots—are routinely used to help prevent pain during healing. These shots are used to prevent pain in selected areas in the mouth so that procedures like fillings, root canals, crowns, or even deep cleanings can be performed effectively and with little discomfort.
The intent of this guide is to give clear and practical information for patients regarding how numbing shots work, what substances are used, and what the patient can expect to encounter beforehand, during, and after the injection. From routine appointments to more involved treatments, being informed about dental anesthesia can help you feel a lot more confident and a lot more smooth regarding your dentist’s appointments.
What Are Dental Numbing Shots, and Why Are They Used?
People generally recognize the tingling sensation which appears as local anesthesia pertains to dental procedures. The purpose of dental injections is to provide pain-blocking effects which produces a comfortable treatment experience.The use of dental numbing shots primarily aims to achieve five purposes.
- Fillings
- Root canals
- Crown placements
- Extractions
- Deep cleanings
When dental clinics administer these injections, treatment becomes efficient and causes very minimal discomfort.
What Type of Anesthesia Do Dentists Use?
Most dental visits involve local anesthesia—a numbing shot that targets only the treatment area. But in some cases, other types of anesthesia may be used:
Topical anesthesia: The use of a numbing gel on the gum surface prior to the injection for calming the discomfort of the needle.
Sedation (oral or gas): Oral medications or nitrous oxide/laughing gas are used to help relax patients when they have a longer or more stressful treatment.
General anesthesia: Used in rare cases. Administered in hospital infrequently in rare cases for the purpose of a surgical procedure or for a patient with extreme dental anxiety. It makes the patient unconscious completely.
Your dentist will always choose the safest and most appropriate method for your needs.
What to Expect When Getting a Numbing Shot at the Dentist
If it’s your first time getting a numbing shot for a dental procedure or you’re feeling nervous, here’s what the process usually looks like:
- A topical numbing gel is first used to numb the surface of the gum.
- Then, the anesthetic is injected using a fine needle beneath the tissue.
- There will be a light pinch or mild pressure but not actual pain.
- The targeted area goes numb within minutes, letting the dentist start the procedure.
Your dentist will always check to make sure you’re comfortable before starting any procedure.
Do Dentists Use Numbing Gel Before the Injection?
Yes—this is one of the most frequently asked questions, and the answer is absolutely.The dental professional applies topical numbing gel to the gums prior to administering the injection. The application of this numbing gel minimizes all pain sensations from the numbing shot procedure. Most people who experience the injection describe a small sense of pressure or a soft pinching sensation at most.
What Drugs Do Dentists Use to Numb the Mouth?
Today’s dental anesthetics are safer, faster, and more effective than ever. While Novocaine was once commonly used, modern dentistry relies on better options.

- Lidocaine (Most Widely Used)
- Articaine
- Mepivacaine
- Bupivacaine
Each drug has its unique benefits, and your dentist will choose the right one depending on your procedure and health history.
Xylocaine vs. Lidocaine: Are They the Same?

How Long Does a Dental Numbing Shot Last?
