[Grammar] Bleeding gums that occurs is the indicative of gingivitis

[kadioguy]

On the package of dental floss, it says:

CAUTION:
Bleeding gums that occurs when first using floss is the indicative of gingivitis. This should recover in 10 days. If not, consult your dentist.

Isn't the word Bleeding gums a plural noun?

Why does it use occurs and is in the sentence?

Thanks!

That's a very badly written sentence.

Bleeding gums, which might occur when first using floss, can be indicative of gingivitis. It should stop within ten days.

The whole sentence is a mess.

Thanks!

It could be both! Taken on its own, it appears to be plural. However, as the name of a condition, it's singular. I don't like its use in the singular in the quote you gave though.

By the way:

"Invading armies have no rights." Noam Chomsky

Is Invading armies a plural noun or singular noun?

An -ing form ('gerund') uses a singular verb, but Invading armies are both the -ing form (Invading) and the plural (armies).

Should it use a plural verb or singular verb?

Thanks!
