A couple of years ago I bought a little set of dental hygiene tools off Amazon. Cost about a tenner, I think. Since then I have used them carefully to scrape stains and tartar off my teeth myself, and clean between them. I also bought a "water flosser" which I use regularly. Along with my electric toothbrush, Tepe brushes of various sizes, and floss, I look after my own dental hygiene. If you have a steady hand it works. Admittedly, I'm blessed to have good strong teeth, none missing and no fillings at 65. I just go to the dentist for a check up once a year.
