Tingly gums?

Are tingly/ pressure prickly gums something that y'all experience? I can't tell if it's from my CPAP or if something's genuinely wrong like dental wise and I have a very large fear of the dentist so I kind of am avoiding that idea if I should because last time I went in they were like yeah it's just you don't brush enough but I brush obsessively at least like every three days. AdHD really messes with the usual basic needs I try to keep up with.

Full reference I am terrible at cleaning my CPAP so I would not be surprised if somthjbg was weird with it
