(Concern) Inquiry about gum health supplement

My husband's gums are very unhealthy.

I have already had four implants.

This is okay, but they say my gums are congenitally unhealthy.

The gums have receded significantly, and the painful areas have been removed. After alveolar bone surgery and implants, it should be okay for the time being.

Everyone else is worried too.

There are a lot of advertisements for gum health supplements.

They even tell me not to eat because I might not realize I have a toothache and therefore miss the opportunity for treatment.

Should I eat or not?

Please recommend what would be good to eat.
