Local anaesthetics are widely used for dental extractions and when filling teeth. But how long do their effects last?
– Novocaine is a popular choice. However, your dentist may use newer medications.
– Modern equivalents often last longer than Novocaine.
– Epinephrine (adrenalin) reduces blood flow and bleeding while lengthening the duration of the anaesthetic action.
The total time for the numbness to disappear is an hour upwards, depending on the dental work, the number of nerves and the area treated.
