After gargling with salt and hot water, followed by a hydrogen peroxide rinse every 4 hours for 24+ hours, the popcorn husk dislodged itself from underneath my gums.

Gingivitis is bad; periodontitis is worse.  Both are preventable.

Flossing after every meal is not just the cheapest and most painless dental health option; it’s also the most effective. By flossing regularly, you can take control of your dental health and prevent many potential issues.

The alternative is 24 + hours of excruciating pain until whatever is irritating your gums frees itself.

I don’t recommend the latter.
