Unfortunately a sand blasted surface filling has come out at the front of mouth. It is unsightly (well only if I wide smile). I am not in any pain. Only on day 17 of generic. How long should I wait for dental treatment in order not to endanger anyone else bearing in mind I couldn't class this as an emergency. Your thoughts please

You will be very close to non infectious at this point.

Most people with Hep C have/had their dental work done with Hep C which is why dentists use gloves and sterilise their instruments.

So Hep C, treated, untreated or on treatment is not a reason not to have dental work done.
