Quoting mama3trish:" That's what it is then-what do you do? He licks garbage cans, chews toys, licks every smooth surface ... [snip!] ... or cloth because he will get it dirty and still suck and chew-and ew just icky? Help me girl, you have all the resources,lol."
lol Redirect, redirect, redirect. Annoying and crazy-mind numbing repeation, but it works.
Give up on the chewelry if he won't use it, find a sort of safe to chew toy or even a nylon dog chew toy (I know, sort of icky, but wash it well first) and let him have that if he will take it, then when he goes for another area, redirect him to the acceptable chew. After time, you can work on weaning him away from that one thing, but it's easier than trying to get him away from EVERYTHING.
If he'll let you, but on a soaker type of absorbant bib that he can chew instead of his shirt. Won't be on the floor, easy to clean and it's something you can take off and hold (so you can eventually take it away, unlike him chewing his shirt).
If you are ok with it, sometimes chewing gum helps - though Kieran just ate it lol
Discovery Toys carries a vanilla scented teething toy that might be helpful too.
And wait it out, it will eventually get better. Kieran started up again recently because of his loose tooth, but stopped once the tooth came out.
