So my DS is teething. To the max

so my question to you, fellow mamas is what are your best tips for releving their pain and making them not cry so much!!
So far we've tried amber teething necklace which he's worn since about 3months, welda teething powder, bonjela, pamol & baby nurofen. Plus teething toys in the fridge. But he just cries and cries and is super clingy
Please help me lol TIA
