The olfactory nerves in the nose send information on the scent to the primary olfactory cortex of the brain. the cortex is linked to the amygdala and hippocampus of hte limbic system. The amygdala is involved in emotion. It projects fibres into the hippocampus. The hippocampus is involved in long-term memory. This is why smells evoke memories

Certain smells can trigger memories or feelings because the olfactory system is closely linked to the brain's emotion and memory centers. When we smell something, the olfactory bulb sends signals directly to the amygdala and hippocampus, which are responsible for processing emotions and memories. This direct pathway can swiftly evoke strong emotional responses or memories associated with the smell.

You can forget the memories or have a hypnotist make you forget things, but that doesn't remove all the other tiny, innumerate changes that have occurred in your brain from ageing and other events.
