What Are Local Anesthetics?

root-canal-therapyLocal anesthetics are a type of dental anesthesia designed to block sensation in a specific area of the body. In dentistry, they’re used to create numbness in the oral cavity, including the mouth, gums, and teeth. This numbing effect is crucial for ensuring that dental procedures are virtually painless.

Local anesthetics function by interfering with the transmission of pain signals from nerve endings to the brain. They achieve this by blocking sodium channels in nerves, preventing the nerves from sending pain signals.

With local anesthetics, dentists can perform a wide array of procedures, such as fillings, extractions, root canals, and gum surgeries, with minimal or no pain for the patient.

Types of Dentist Local Anesthetics

There are several types of local anesthesia used in dentistry. Our dentist will always inform you of what is being used before your dental treatment.

Common local anesthetics include:

  1. Lidocaine: One of the most commonly utilized local anesthetics in dentistry. It’s renowned for its rapid onset of action and effectiveness in providing relief from pain.
  2. Articaine: It’s gaining popularity in dental practice due to its high potency and ability to perform well in inflamed tissues, making it an excellent choice for certain dental procedures.
  3. Mepivacaine: This is preferred when a longer-lasting numbing effect is required. It’s particularly suitable for more extended and complex dental procedures.
  4. Prilocaine: This is often chosen for patients who may be sensitive to other local anesthetics, as it carries a lower risk of causing allergic reactions. While allergic reactions to local anesthetics are rare, they can range from mild symptoms to severe reactions, and it is important for clinicians to be able to identify and manage such reactions.
  5. Bupivacaine: Used in situations where prolonged anesthesia is necessary. It offers an extended duration of action, making it suitable for specific dental treatments.

How a Local Anesthetic Is Administered


The most common method of administering a local anesthetic is through injections. These injections are usually targeted at the gum tissue or near the nerves of the affected area.

Techniques such as the Inferior Alveolar Nerve Block (IANB) are commonly used to target the inferior alveolar nerve for effective anesthesia in dental procedures.

Topical Anesthetics

Before administering injections, dentists often apply topical anesthetics to the surface of oral tissues. These topicals numb the area, reducing the pain associated with the insertion of the injection needle.

The Wand (Computer-Assisted Anesthesia) for Pain Signals

The Wand is a computer-assisted system designed to precisely control the flow rate and pressure of the anesthetic solution during injections. This advanced technology enhances the accuracy and comfort of the injection process for patients.

Dental Procedures Where Local Anesthetics May Be Used

  • Dental Fillings: A local anesthetic is frequently used when dentists need to remove decayed tooth material and fill cavities.
  • Tooth Extractions: When a tooth needs to be removed due to severe damage, infection, or orthodontic reasons, a local anesthetic is administered to numb the area around the tooth, making the extraction painless.
  • Root Canal Therapy: Root canals involve the removal of infected or damaged pulp inside a tooth. Anesthetics are essential to numb the tooth and surrounding tissues to alleviate pain during this procedure.
  • Temporomandibular Joint (TMJ) Injections: In cases of TMJ disorders or jaw pain, a local anesthetic may be used for therapeutic injections to alleviate pain and discomfort.
  • Periodontal Treatment: Periodontal treatments such as scaling and root planing, which aim to treat gum disease, may involve the use of local anesthetics to make the procedure more comfortable.

Frequently Asked Questions 

When administered correctly by a trained dental professional, local anesthetics are generally safe. Most risks arise from factors such as overdose, allergic reactions, or improper administration.

For certain minor dental procedures, alternatives such as nitrous oxide (laughing gas) or conscious sedation may be considered. However, these options depend on the procedure’s complexity and the patient’s preferences, and they should be discussed with the dentist.
