Hold the floss tightly against the tooth. Gently rub the side of the tooth, moving the floss away from the gum with up and down motions. Repeat this method on the rest of your teeth. Don’t forget the back side of your last tooth. Once you’re finished, throw the floss away. A used piece of floss won’t be as effective and can reintroduce bacteria into your mouth.
Underneath the enamel is a pale brown substance called dentin, which can become more visible when enamel gets thinner — a very common occurrence for many adults. (2) Dental erosion (erosive tooth wear) results from chronic loss of dental hard tissue that is chemically etched away from the tooth surface by acid and/or chelation (without bacterial involvement). (3) What are some of the reasons enamel thins? Risk factors include aging, genetics and intake of foods that promote erosion and/or staining. Many of these same unhealthy habits also increase your risk for gum disease.
