Periodontitis
Periodontitis is pretty much the worst thing that can happen to you form a dentist’s perspective. This is a condition whose name means ‘disease of the tissue around the teeth’, and that is exactly what this is. Periodontitis can affect the gums, alveolar tissue, and indeed even the bones in which teeth are anchored. This disease can cause tooth loss, blood poisoning, and even death.

I have never believed in loyalty towards brands, and this is especially the case with cosmetic products. I usually buy whatever I feel like when looking at the box of the product. The only thing that I do buy from the time to time - perhaps because I used it as a child- is Elmex brand anti-tooth decay paste.
I can remember the way toothpaste used to taste when I was a kid. We had a much smaller variety to choose from, but we had nice, healthy teeth anyway.
