Local anesthesia is a medication used to temporarily numb a specific area of the mouth during dental procedures. It works by blocking pain signals from nerves in that region—so you can stay awake, aware, and completely comfortable while your dentist works.
Local anesthetics are commonly used for treatments such as:
Fillings and crowns
Extractions or oral surgery
Deep cleanings or periodontal therapy
Root canal treatments
Minor soft tissue procedures
At Cornerstone Dental Arts, our doctors use advanced delivery techniques that make numbing quick, precise, and virtually painless.
Many patients worry about the “shot” more than the procedure itself—but our team is known for making numbing comfortable and stress-free.
We use:
Topical anesthetic gel to pre-numb the area before any injection
Ultra-fine needles for minimal sensation
Slow, steady delivery techniques to reduce pressure
Calm communication and gentle reassurance throughout the process
For patients who feel anxious, we can also combine local anesthesia with nitrous oxide or sedation options for added relaxation.
Most local anesthetics begin working within minutes and last one to several hours, depending on the procedure and medication type.
We’ll let you know exactly what to expect—including when normal sensation will return—so you can plan your day comfortably after your appointment.
At Cornerstone Dental Arts, your health and safety always come first. Our team carefully selects anesthetic types and dosages tailored to each patient’s medical history, treatment area, and comfort level.
Modern anesthetics are highly effective and have an excellent safety record, even for patients with mild sensitivities or medical conditions.
Will I feel pain during my procedure?
No. Local anesthesia completely numbs the treatment area so you remain comfortable throughout your visit. You may feel light pressure, but not pain.
How long does the numb feeling last?
Typically between 1–3 hours, depending on the anesthetic used. We’ll let you know when you can safely eat or drink afterward.
Can I drive home after local anesthesia?
Yes. Because local anesthesia doesn’t affect alertness, most patients can safely drive or return to normal activities soon after treatment.
Is local anesthesia safe for everyone?
Yes. Local anesthetics are safe for nearly all patients, including children and those with most medical conditions. Your dentist will review your health history to ensure complete safety.
