dental floss
Have you had a root canal yet? I did and hated it. Unfortunately, that was only the way to save my tooth. The alternative of wearing false teeth or having a fake tooth planted into my gum wasn't attractive.

Receding gums, loss of teeth. These are signs of aging. Then again, if you take the pains to care for your teeth properly, you could keep them a lot longer. The usual advice, brushing your teeth when you get up and at bed time and after meals still counts. Only problem is that the toothbrush and toothpaste only gets rid of half the junk stuck between teeth. You really need dental floss for a more thorough cleaning which makes all the difference.

Flossing your teeth helps preserve them longer. The six monthly checkups are important too to stop problems before you end up losing your teeth. At the same time, the cleaning the dentist provides goes a long way in keeping those cavities at bay. My root canal problem was due to a cavity that was allowed to go too deep. Nothing could save the tooth. I ran out of dental floss and stopped flossing for days which went on for weeks and by then, the decay had set in. I had also skipped the dental checkups for two years and the root canal cost me a lot more than I would have paid if I had gone to the dentist regularly.
Stock up on your dental floss so you don't run out. Your teeth depend on that.
