I actually had gold first but bacteria got under it a few years later and the dentist had to redo it and this is what he replaced it with. I should ask him why.. maybe he wanted me to come back and put a porcelain one after being fed up of looking at this one lol (he actually mentioned replacing it with porcelain for a perfect set the last time i went for a check up lol). I’m not really fussed tho, it’s at the back and can’t be seen when i talk or laugh 🤷🏾♀️
