Some piggies are plastic addicts; in this case, you'd best remove any plastic from their reach.
Try apple or pear twigs instead.

Please be aware that while wooden chewing toys can be fun, it is the actually the silica in the unlimited hay supply (80% of the daily food intake) that keeps the crucial back teeth ground down and the guts balanced. The front teeth are self-sharpening and don't need any clipping or any chewing toys to stay exactly as they should.
