Which topical anesthetic is commonly used in dentistry?

Lidocaine gel is commonly used in dentistry as a topical anesthetic because it provides effective pain relief rapidly and its effects can be felt within minutes. The use of lidocaine in gel form allows for easy application to mucosal surfaces, making it ideal for procedures such as scaling, prophylaxis, and local anesthetic infiltration. Lidocaine has a well-established safety profile and proven efficacy, which enhances its acceptance in dental practices.

Topical anesthetics like lidocaine gel work by blocking nerve conduction in the application area, thereby reducing the sensation of pain during dental procedures. This property is crucial in treatments where patients may experience anxiety or discomfort, allowing for a more pleasant experience.

In contrast, while benzocaine ointment is another topical anesthetic option, it is less commonly used in modern dentistry compared to lidocaine due to its slower onset and shorter duration of action. Procaine and Novocaine, while once popular in the past, are not commonly used in current dental practice for topical applications. This makes lidocaine gel the preferred choice in contemporary settings for achieving effective local anesthesia during various dental procedures.
