Everything You Need to Know about Dental Local Anesthesia

Your dentist might need to apply dental local anesthesia to numb an area of your mouth while performing certain procedures. We do this by injecting medicine – known as a local anesthetic – into your inner cheek or gum.

Nowadays, the most common anesthetic dentists use is Lidocaine. Novocain used to be the more common option a few decades ago, professionals now use other anesthetics that work better and longer. The one thing all these anesthetics have in common is their names ending with "cain."

Modern anesthetics are also less likely to cause allergic reactions compared to Novocain. The numbing agents in these anesthetics are only a fraction of what is injected into your mouth at the dentist’s office. Other medicines in the solution include:

The two types of numbing injections that are commonly used by dentists are:

1. Block injections – These cover an entire region in your mouth like one side of your top jaw for example.

2. Infiltration injections – These numb a much smaller area, only the area surrounding where the injection was applied.

When you undergo a procedure that requires dental local anesthesia, your dentist will prepare your mouth by drying a part of it with cotton or air. Your dentist might also decide to numb the area he/she plans to inject with a gel to numb the skin. This can be helpful if you are afraid of injections.

Your dentist will then inject the anesthetic into the area he/she wants numb. You will rarely ever feel the needle. The only sensation most people feel is the sting of the medicine moving into your tissues.

These anesthetics can last as long as several hours. That means you might find it difficult to speak clearly or eat for up to seven hours after receiving anesthesia. Also, avoid eating with the side of your mouth closest to the area that was numbed until you regain feeling there since it’s possible to hurt yourself and not realize it.

Common side effects of dental local anesthesia

Anesthetics are the most used drugs in dental offices and it’s very rare for patients to have negative reactions to them. The rare side effects associated with anesthetics include:
