Many decades ago, (back in the 1980's)I was struggling financially - hubbie had MS, and we had a largish young family. Went to dentist to have a filling replaced, and he told me that unless I made an appointment with his newly appointed HygIenist for £25, I would have severe gum disease and lose all my teeth painfully over the next five years. I left there in tears - no way could I find that £25.
Now,forty years later, at age of 85 have all but two of my teeth and no gum disease.
Last time I did go to hygienist (2019), she was so brutal, and left me with a very sore mouth for the whole of the following week, I swore I would never go again.
Look after my teeth carefully on a daily basis, user a water flosser a couple of times each week, and a twice daily careful clean with electric toothbrush. Attend NHS dentist for check up every nine months - had no treatment needed since 2018!!! Always ask them to do clean and polish.
