Oh, well, the important thing is that people brush their teeth, because that's the only thing we can do to keep our teeth. If you don't take care of them, then study at https://smilebydesigndental.com/implant-dentistry/ about how implants work and go to the clinic to put them in. Personally, I would like to save mine, so I try not to skip brushing my teeth in the morning and evening. Especially nowadays dental medicine is very expensive.
