Does dental adhesive cream pose a danger to tooth implants for snap-ins?

I spent a lot of money at my dentist (who is considered one of the best in this field) to renew and fasten my three snapins that hold my lower denture. The snaps wear out within a week and the denture comes off when I bite into food or drink something, just like before I paid all that money! Is there something I can do to fix it myself? If I use a dental adhesive cream instead on the implants and the denture, will that cause harm to anything?
