Dental experts! what is the quickest way to get rid of a pimple?

Gums ?: Your post did not say. A "pimple" can be a fistula, which is a draining abscess. Can't tell if that is your problem, over the internet. But the quickest way to resolve a dental problem is to have your local dentist treat you. Make the call...

Vague: If there is a pimple like lesion on your gum tissue, then you may have a gum/periodontal infection, a tooth infection or both. See a dr. Asap.
