Over the last 10 years I’ve gone from utter certainty I don’t need this and a bit of an eye roll at the trend to becoming more conscious of my teeth and now I think they are the thing that age me the most. I can probably blame Zoom calls, UHD TV and social media.
When I was researching this I found a few mumsnet threads of various ages but actually not as many as I thought. So if people are interested and would find it helpful I can do a kind of diary of how I get on and answer any question you have.
