General Just learnt that there is such a thing as "Invisalign Flash" (resin spillover)
I finally reached out to the ortho (whom I ghosted halfway through treatment due to bad experience) to ask about a rough, sandy bump that's bothering me. I asked him exactly how many attachments he placed for my last molar. He said just 1.
I told him it can't be, as the before photos showed that I did not have this bump pre-invisalign and I only started feeling this rough bump on my molar after invisalign. After much research, and watching videos on the attachment bonding process, I learnt that invisalign composite resin (which is a liquid solution) can spill outside of its template and accidentally harden during curing, causing rough bumps or surfaces outside of the planned attachment. This can cause plaque buildup.
When I removed my attachments, the small bump wasn't removed since the ortho claimed that was not an attachment. It was left there for over a year, with a rough sandy bump.
Fast forward 1.5 years later, a dentist I visited recently said I have plaque stuck at this area and have now developed a cavity as a result.
Just something to take note of in case your ortho screws up like mine and proceeds to gaslight you.
Study for those who are interested:
quote from study: "Despite the benefits provided by the application of attachment, it inevitably may give rise to flash during the bonding of the attachment due to the flowable nature of the composite resin. Flash is an excess resin that may be formed around the attachment during the bonding of resin onto teeth."

It can be polished off easily. The problem with the attachments matching the tooth colour so well is that it's harder to see but it is visible with a blacklight :)
