Is local anesthesia safe?
Local anesthesia when administered in proper dose, is very safe. People often use the term “novocaine” when talking about local anesthetics… even though novocaine has not been used in dentistry for decades (both because it wears off too quickly and because allergies to novocain and other ester-based -caines are relatively common). All the -caines used for local anesthesia these days are amides rather than esters.
