Does anybody have tips for helping teething babies?

Ellen • Proud first time mama! My beautiful daughter, Roxie Marie, was born on April 23rd, 2016. I love my baby girl. :)
My daughter is about 6 months old & is generally the happiest baby I've ever seen. But her naps are only 15 minutes to a half an hour because of her teething. I try to give her teething rings & stuff, but they only help for so long. Do any of you mamas have any tips to help with teething?
