Having a local anaesthetic for some can be a traumatic experience. A chance discovery by Ear Nose and Throat medics noted that when using a local anaesthetic in this area numbing of their patients gums occurred. US researchers at the State University of New York at Buffalo have developed a nasal spray that with further research could mean no more injections at the dentist. Wider population tests could come as early as March 07. How deep the anaesthetic is and for what type of dental work it will be suitable for will be interesting to see. It may mean a reduction in one of the dental phobiasthe fear of injections, estimated to be about 8% of the UK population (The Adult Dental Health Survey UK 1988) Now we just need something to help us in foot care !
