Great suggestion - I have quite a selection and find them very useful for many things - they can be easily modified for a specialist situation, too. The "modeller's picks" are not made from such hard material as the genuine dental picks. This can be to your advantage, if you do want to alter them a bit.
I would suggest that, if you have the option, the single-ended picks are a little easier, and safer, to use.
With some decent ear defenders, a strong chair and a roll of gaffer tape, you could even try a little impromptu dentistry.
