Before I got teething rings I would wet a corner of a baby wash cloth and freeze it. That way the rest is not cold just cool and they can hold on to it. I bought 5 rings and keep them in the refrigerator. Hope this helps. I also used teething gels with chamomile
I wet a washcloth and place it in a zipped up plastic bag in the freezer. Leave in there for about 40-60 minutes then give it to my daughter. I also make some chamomile tea and with a washcloth rub some tea on her gums.
Other than that I use frozen teething toys; orajel and Motrin or Tylenol.
