Dental Nursing at Portsmouth

Hi all just need advice,
So I have applied for Dental Hygiene and Therapy to 5 different universities, where I had two for for Portsmouth (Dental Hygiene and Therapy and just Dental Hygiene).
I got rejected for all 4 and then for Portsmouth Dental Hygiene and Therapy they gave me an offer for Dental Nursing instead for one year. Should i take this offer or look for completely different courses through UCAS extra. I think all my rejections were mostly because of work experience as I just did work shadowing in a clinic over 2 days. I'm just really scared after the dental nursing program I won't have progression opportunities, as it is also a diploma of higher education and not a degree.
Someone please give me your opinion, as Dental Hygiene was always something I wanted to.

Hi, similar thing happened to me.Im gonna go with the dental nursing course, then do a 2 year top up in DT&H, which portmouth offers xxxx
Hope this helps you stay at ease a bit
