Happy Tooth
From Wikipedia, the free encyclopedia
The Happy Tooth is a registered trademark which stands for guaranteed toothfriendly quality.
The Happy Tooth mark distinguishes products that are not harmful for teeth. All products carrying the Happy Tooth symbol have been scientifically tested and found not to be cariogenic or erosive.
The compliance of a product is tested by means of intraoral pH telemetry. Applying a standardized method, the plaque pH is measured at least in four volunteers during and for 30 minutes after consumption of the product with an indwelling, interproximally placed, plaque-covered electrode. Products which do not lower plaque pH below 5.7 under the conditions of this test, lack a cariogenic potential. The erosive potential is measured with a plaque free electrode. The acid exposure of the teeth must not exceed 40mmol H min.
The test is conducted by independent university institutes.
Toothfriendly International grants the rights to use the trademark.
