Dental A to Z
Lignocaine
A local anaesthetic commonly used in dentistry and often combined with 2% adrenaline to prolong the effect by reducing the blood flow. A dental anaesthetic can last for as long as 3 hours and patients should take great care not to drink very hot fluids or chew on the affected side until the normal sensation has returned. It is very easy to bite the anaesthetised area and cause serious soft tissue damage and ulceration.
