How to overcome failed local anaesthesia

Br Dent J. 1999 Jan 9;186(1):15-20. doi: 10.1038/sj.bdj.4800006.

Abstract

Local anaesthetic failure is an unavoidable aspect of dental practice. A number of factors contribute to this, which may be related to either the patient or the operator. Patient-dependent factors may be anatomical, pathological or psychological. This paper considers the reasons for unsuccessful dental local anaesthetic injections and describes techniques which may be useful in overcoming failure.
