Visitor asks:

Dear Sir/Madam!
Today I went to the dentist, who gave me a local anaesthetic injection. It has now been 3 hours and I still cannot feel anything in that area.
I would like to know after how long the injection should wear off.
Kind regards.

Dentist Tomaž Rotar answers:

Dear Sir/Madam!

Terminal infiltration anaesthesia, used mainly to anaesthetise teeth in the upper jaw, usually wears off relatively quickly (1 to 2 hours). A nerve block, used when working in the lower jaw in the posterior region, can last considerably longer (5 hours).

Have a nice day!
