In some instances, dental treatments go beyond routine cleanings and check-ups. Given the sensitivity of your teeth and gums, certain procedures may necessitate the application of local anesthetic medication to induce numbness.

You might have heard of Novocain as a numbing agent, but it's important to note that Novocain is no longer used. Modern dentistry relies on safer and more effective drugs such as lidocaine. These drugs are often combined with other substances, such as vasoconstrictors, to enhance their efficiency and prolong the duration of the anesthesia.

There are two primary types of local anesthetics employed by dentists to numb your mouth. First is the topical anesthetic, which is applied to a small area on the surface of your mouth or gums. Typically, this numbs the region where the dentist will administer the injectable anesthetic—our primary tool to ensure your comfort and pain-free experience.

Understanding Local Anesthesia:

Local anesthesia is employed to temporarily desensitize a very specific area of your body, rendering it insensitive to sensations, including pain. Procedures like fillings, crown placements, and root canals often call for local anesthesia.

The mechanism of a local anesthetic involves blocking nerve cells in a particular area from transmitting pain signals to your brain. The resulting numbness generally persists for two to four hours, which may lead to residual numbness even after your appointment.

Before undergoing a procedure requiring local anesthesia, we will gather information about any allergies and medications you are taking. Depending on your medical conditions, you might need an alternative formulation. Feel free to contact us with any concerns or for further insights into our application of local anesthesia.

What to Anticipate:

Despite the topical anesthetic's numbing effect, some patients might experience a stinging sensation from the injection, misconstruing it as ineffective. In reality, this sensation results from the anesthetic entering your body and commencing its action. The stinging sensation subsides within seconds.

Potential Side Effects:

While local anesthesia does have potential side effects, they are typically mild. One recognized side effect is a transient rapid heartbeat, which may occur if the anesthetic is injected into a blood vessel. Epinephrine, a component of the anesthetic, can directly impact the heart by accelerating the heart rate. You might recognize epinephrine as adrenaline, a natural substance that can swiftly elevate heart rate. Although the heightened heart rate can be alarming, it is not hazardous and usually normalizes within seconds.


Numbness from local anesthesia might persist for a couple of hours, affecting speech and eating. After your appointment, caution is advised during biting and chewing to prevent unintentional tongue or cheek bites, as you won't feel them. Temporary swelling or partial drooping of mouth or facial parts might also occur. Some patients might experience temporary inability to blink, though this is not a cause for concern. If needed, the dentist can apply tape to protect your eye from drying out. Normal blinking will resume as soon as the anesthesia wears off.
