The elmex eco-clic is a toothbrush with replacement heads that combines medical and environmental benefits. The optimally rounded bristles and differing bristle heights ensure thorough cleaning. The replaceable heads also mean 70% less waste and 50% lower costs.
Egg test
Since the structure of eggshells is similar to that of enamel, the effect of amine fluorides (in elmex products) can be demonstrated using an egg: placing a chicken's egg in an egg-cup filled with elmex gel for 3 minutes increases the acid resistance of the eggshell. If the egg is then rinsed off with water and placed in household vinegar, the shell will only dissolve, as demonstrated by air bubble formation, at those points where the acid-inhibiting protective layer is missing.
Enamel fluorosis
Condition resulting from prolonged overdosage with fluoride. The mildest form produces white flecks on the enamel. Fluorosis occurs if excessive quantities of fluoride are regularly absorbed between the ages of 6 and 8 years.
Enamel outer film
Teeth are always covered by an acellular proteinaceous film, the pellicle. The pellicle forms on the "naked" tooth surface within minutes to hours after professional teeth cleaning.
Erosion
Enamel wear caused by chemical and physical processes. Example: Frequent and regular consumption of fruit acids leads to erosion = loss of tooth substance.
