M.H.
Are you sure that teething is the only problem? If you have good insurance, a trip to the doc, to make sure the ears are not infected might not hurt. My dauther had a double ear infection, no fever, only sympotom was not drinking her bottle, and biting-wich is usually teething. I was shocked when they said it was a double ear infection. There were virtually no signs.
We do Hylands Teething Tablets, they did the trick. You can also take the soft pacifiers, wet them put them in the freezer and let him chew on them. Frozen wash clothes also work.
Good Luck.
