I think my kitten might be teething.

Recently, she's started gnawing on anything she can get her hands on. While she seems to understand that the power cords are off limits (I've done everything I can to block off her ability to get back in where the majority of them are, and she seems to leave the ones that are still out in the open alone), just in the last few days, I have caught her gnawing on the edge of the stool in the kitchen, my bedside table, the corners of my laptop, my blankets, my towels, the bars on the front of the carrier, and, rather unfortunately, my hands and my feet whenever she gets the opportunity.

I'm not particularly worried about her hurting anything, but I was wondering if anyone had any suggestions for things I could do to get her to focus more on her toys than the furniture or other potential items that I could provide her to relieve whatever teething woes she might be going through. I've been doing toy substitutions whenever I have caught her, but she often ends up getting bored with the toy (or it doesn't provide the relief she needs), and she immediately goes back to whatever she was gnawing on in the first place.

You didnt say how old your kitten is, but I've found when the babies start teething, they particularly like to gnaw on cardboard boxes, chewing on the flaps or the edges of the box. They also seem to like chewing magazines and the edges of their cat scratcher. 

We're not really sure how old she is. She was a solitary stray when she was brought to the shelter, but she was already eating solid foods and was a decent size. The shelter told me she was probably around 4 months, or 16 weeks old, when I adopted her, but when I took her to the vet to get her 12-15 week shot panel, the vet said that she was probably more around 6 or 8 weeks, 10 at the most. 

That was a little over month ago, so she's probably somewhere between 10-15 weeks right now.
