In general, dental hygienists are desirable women based on their non-careerist job. Not all dental hygienists and paralegals will be worth dating.
Most men, including the blue pill beta males, realize that the most desirable women aren't career women. One's job is such a crucial part of their identity and a big part of dating/lifestyle. Since dental hygienists are not burdened by excessive career demands, many men see them as relationship worthy. The more overweight hygienists will struggle more, but if a hygienist is under 35 and at least average looking, she'll have a lot of options and men will value her in terms of longer term relationships. This is why most hygienists have a child by 34-35. Men recognize their value and want to commit to a woman without a demanding career longer term. Most of these women get snapped up by their mid to late 20s. With hygienists under 30, they are rarely single for long when a non-marital relationship fails, regardless of whether or not they use swipe apps or not. Hygienists don't have to work hard to find good quality approaches from the real world or they might have a social circle. If neither of those options work, they have their social media DMs if they are social media active. The swipe apps would be the 4th possible option for them if the first three fail. Most hygienists will be able to find a boyfriend through their social circle or getting approached in-person though within 2-3 months of being single.
There are some high notch count hygienists. These women find LTRs in part due to the green flag nature of their jobs and also in part due to the male thirst environment. These are the hygienists that are more likely to eventually become single moms.
A typical unattached male without a good social circle only interacts with dental hygienists when he sees his own dentist. His own hygienist could be married woman and/or a woman who is 45-65. If a man's dental office has a hygienist who is under 35 and unmarried, she is likely to already have a stable boyfriend and not be looking for new penis. If a man's dental office has a hygienist who is under 35, unmarried, and not in a relationship/seeking new penis, he's also not likely to be able to arrange a date while sitting in the dental chair. Hygienists are like retail store workers, waitresses, bartenders, breastaurant workers, and strippers. The best way to get a date with a hygienist is to somehow meet them while they are off the job and participating in some sort of leisure time activity. This could happen in a conventional daygame setting, at a nightlife venue, or in something like a co-ed sports league or dance class.
It's very difficult to meet a dental hygienist, paralegal, phlebotomist, or other medical assistant at a bar or in daygame.
A typical unattached male without a good social circle may meet a dental hygienist while swiping on an app as well or sliding into her DMs, but that's an even more difficult way to try to meet a dental hygienist. Some hygienists may mention in their swipe app profiles or Instagram bios that they are hygienists.
This thread is a bizarre thread in general because most single men are not hitting on their hygienists while at their dental appts 2-3 times per year.
