About topical anesthetic gel
A review describes gels and ointments as effective for pain from a laceration or abrasion, and as able to relieve pain at the point of a local anaesthetic injection. It adds that gel agents may be used before infiltration anaesthesia to reduce the pain and discomfort caused by the needle. Benzocaine is produced as a spray, gel, gel patch, ointment or solution at a 6 to 20 percent concentration depending on the maker. At 20 percent it produces an anaesthetic effect within 30 seconds but requires approximately 2 to 3 minutes to reach adequate depth, and the effect then lasts approximately 5 to 15 minutes.
The form a review pairs with the injection site, applied before infiltration anaesthesia. A review reports that benzocaine reduces pre-injection pain in the alveolar mucosa and works on the tongue, but is hardly effective on the palatal mucous membrane, which is thick and firm with densely packed nerves.
