What is tetracaine? | Dental Treatment Guide


Tetracaine is an effective topical anaesthetic used today. It dissolves in water and it spreads throughout the body’s tissues quicker than the other anaesthetics. Tetracaine can be used in conjunction with benzocaine so that gag reflexes are reduced when taking impressions or x-rays. The start of the numbness is very fast and it lasts for around fifteen minutes. The anaesthetic combination is given in the form of a spray and it must be used carefully. Tetracaine easily penetrates the mucous membrane in the mouth and it enters the bloodstream so it must be used with caution. If you get overdosed then you may get severe toxic reactions and you may even die.
