This year is the first year I had dental benefits (calling it 'insurance' is silly)* since I graduated from college. I just paid cash for cleanings/exams and, unfortunately, all 4 wisdom teeth removed. Sadly, good jobs with good benefits packages have been hard to find for a long time.
Then I moved to a different region and it took a while to find an honest dentist and find the time to go. My first cavities popped up in that visit.

At least I had dental benefits but I am needle-phobic. I hope your dentist does a first class job! I also hope our healthcare providers start making cash deals easier to do.
*Warning: rant follows.
"Insurance" is meant to cover unforseen, significant misfortunes. You bust your wrist. Your pipes freeze, a deer totals your car, or another driver totals a family member. The BIG stuff. A sinus infection, chip in your windshield, new eyeglasses, or a couple of cavities really don't belong in the sphere of "insurance" because they are high probability, predictable/forseeable events. However, if your eyeball gets injured or a tooth gets knocked out in a fall, that IS usually covered by health insurance.
If you look into buying dental 'coverage' on an individual basis, you find that you're spending between 1/3 and 1/2 your annual coverage limit in the premiums you pay each year. There are also waiting periods of 6 months to a year on anything other than basic cleaning/exam. If you get dental benefits with your employer, you won't have the waiting periods for coverage. If your employer isn't paying anything toward the premium, though, the math still stinks.
If you're north of 40, you have a good chance of needing eyeglasses. Budget accordingly. And keep in mind the above if you're asking yourself why "coverage" on these are not always included on employer plans and most definitely not on individually bought policies.
I am not accusing anybody here of whining like an Occupier! But we did a number on our mentality as we built the notion that Anything healthcare-related "should" be employer-paid. Or government-paid, depending on the complainers' political beliefs. This rant honed during several years of working in an insurance office.
