When DD was particularly bad, I would give her panadol and neurophen together as well as SM33 on a special teething dummy (it is shaped like a mouth guard). I keep the teething dummy in the fridge so it is always cool and soothing on the gums. She can also move it to chew where she needs it. The gel on it allows her to place it where needed without getting my fingers chomped!!!

Other than that - loads of cuddles and distraction.

Hope you get some respite soon.
