I ended up letting them rot until they needed pulled, and that was something I wish I could take back today. I eventually was able to afford to get two dental bridges put in, but I've had issues with them off and on ever since: one of the anchor teeth needed a root canal and eventually cracked in half, now I need to get that and the other tooth pulled and get implants at some point.
And I've got pretty bad gum issues around one of the anchor teeth (a pocket of size 5, just under serious periodontal disease) on my other bridge, and have gotten it deep cleaned and given antibiotics under the gumline a few times that so far hasn't reversed the process at all.
If I could go back in time I'd be more diligent about dental hygeine, and/or would have borrowed money from someone or sought cheaper ways to get those crowns in, because it's a lot easier to keep crowns flossed than bridges.
Sadly can confirm as I had no cavities in high school, did terrible in my 20's especially around 20-27 went through a lot of depression, lack of money/medical care/ in and out of work a lot and I'm trying to fix what I can just starting my 30's after losing 2 teeth It can be hard to overcome shame when already depressed so it's hard to visit a dentist moreso if you have no money to do anything.
It's easy to screw up even more so if you have bad genes on top of it, a lot of my family has issues with teeth.
At least stem cells can be found within your teeth and there is a process now to regrow some of your teeth with your own stem cells, doesn't replace implants though but helps. This process isn't popular yet but at least it's possible in a few areas in the states.
