OHE course you can do online with the BDA but its very pricey and a lot of work, you need to see 10 different people from different categories and for 30 mins each on at least 2 occasions, you need to make sure your practice will allow this. and you have to make a stand and it has to be for a specific audiance like children or sensitivity etc. and you have to do 2 essays before you can even sit the exam which is extra money again ont top of the fees to do the course.
i started the OHE course but never completed it as my practice would not allow me 30 mins with the patients so i had no way of completing it to get my record of experience.
the xray course is a good way to go? its very hard but you can do it whilst working as you do essays and take xrays which every practice does on a daily basis? again its very pricey and make sure your practice will allow you to take the xrays and again there is an exam fee on top.
i have been nursing 7 years and have only got the national certificate in dental nursing, im starting the radiography course in march, sedation in june. i would like to be a hygienist / therapist but to get into most college/unis you need A levels lots of experience and extra qualifications to stand out from the other candidates. get as many qualifications as you can whilst getting more experience then that will set you in a good posistion
