Hi Becky,
I done the hygienist course 3 yrs ago after been a nurse for 16 yrs it was a great course to do and I enjoyed it, with the knowledge from been a dental nurse I didn't fine it difficult, as for finding a job when I first finished I found a job within a few weeks but had to wait for my reg docs to come throw which took 6 weeks
.......
There is an increase in jobs now as the economy is getting better and dentist are employing again.
do the x-ray course it will increase your chances of been excepted its not that expensive about £500
