,This gentleman had a new implant retained lower denture made elsewhere in a very light shade. He asked me to make a new full upper denture, but he wanted it to look natural. If I made it to match the lower, the colour would have been way too light to look natural.
I ended up using a light colour for the 2 front teeth (A1), a slightly darker shade for the next 2 front teeth (A2) and an even darker colour for the canine teeth (A3). The end result was a denture that matched the lower but still retained a natural look. With a small gap between the front teeth the natural look was complete.
I've just started a new full set of dentures for a gentleman who wants the "Hollywood" impossibly white teeth look. This is not normally something I'd recommend.
