Satisfying for my son but I wonder.....

Got these for my son who has an oral fixation. This necklace has been satisfying for him. I gave it 4 stars because I'm torn-I'm glad that this necklace is more sanitary and safe for him to chew. My son often chewed on toys or his shirt. However, I am wondering if this will encourage his chewing. Ultimately I would love to see him stop chewing on things all together. Will this product perpetuate this? Time will tell.
