Topical anaesthetic is the application of gel to the distinct area of soft tissue where the surgical site is. Thereafter, the gel is left for a few minutes to ensure that it works effectively.
Purpose: to numb the gums or cheek before local anaesthetic is injected.
This type of anaesthetic works great on the surface of the gums. However, if the surgery requires any drilling, it will have to be followed by a local anaesthetic injection to reach the nerves deeper inside. At times, It is also used to remove loose deciduous teeth in children.
