Scientists have developed a nasal spray that could do away with painful anaesthetic injections for dental procedures.
The spray, Kovacaine Mist, was as effective as standard anaesthetics in four out of five patients, according to researchers at the University of Buffalo.
The product has passed phase two clinical trials in the US, 'The Independent' reported.
Safety trials with the US Food and Drugs Administration could be complete by the end of the summer and final product approval in the US could be achieved by next year, according to the manufacturer, St Renatus LLC.
"This nasal spray could be a very promising addition to any dental practice," Carter said.
