Which local anesthetic is preferred for short dental procedures due to its rapid onset?

Lidocaine is preferred for short dental procedures due to its rapid onset of action, typically within 2 to 5 minutes. This characteristic makes it particularly effective for situations where quick pain relief is necessary, allowing for efficient and smooth dental treatment. Lidocaine’s potency and appropriate duration of anesthesia (about 1 to 2 hours for infiltration) make it suitable for short-duration procedures, ensuring that patients remain comfortable without the extended effects of anesthesia that could complicate recovery.

In contrast, other local anesthetics like bupivacaine are known for their longer duration of action, making them better suited for longer procedures rather than those requiring rapid onset. Prilocaine and mepivacaine have their own specific pharmacokinetics and potential use cases, but they do not match the quick onset that lidocaine offers. Therefore, when the emphasis is on speed and efficiency for short dental visits, lidocaine is the go-to choice.
