Teething tips?

ma

My baby is now 15 weeks. He has been teething from very early (drooling started at 5 weeks then teething kicked in properly at 7 weeks!!). Today was v bad in particular - I'm looking for any tips to help him as it's just heartbreaking seeing him in such pain and discomfort 💔 I have tried teething powders, teething gels, teething rings, damp cloth in freezer, calpol, nurofen, teething mitt etc. Please give me any tips that worked for you mamas!!
