My grandson was a prem baby and was not allowed to use any serious sedative meds or any of the stronger teething gels. He had a fever and started getting an infection in the area where his first two teeth were cutting.
I ordered the teething roller out of desperation, which made an incredible difference! Relieving pain and infection and they came out beautifully.
Upper teeth are showing now, almost out, but without all the irritation, drooling, and sleepless nights. It works!
