local anesthetics
Targeted pain blockers
Local anesthetics are drugs that block nerve signals in a specific area of the body, producing numbness without affecting consciousness.
Dentists inject them before drilling; surgeons use them for minor procedures.
Common examples include lidocaine and novocaine.
The effect is temporary—sensation returns as the drug wears off.
The local anesthetic made my whole jaw feel numb.
