Tooth Fairy Day

February 28 is Tooth Fairy Day. This day serves as a reminder of an old ritual: If a child’s baby tooth falls out, he or she receives a coin for it. Similar to how the tooth fairy uses a magic wand, the dentist uses light guide rods from SCHOTT to bring light to the teeth of adults.

When a child loses a baby tooth, the Tooth Fairy comes. This nighttime visitor secretly replaces the tooth under the child’s pillow with a coin or a gift. With this transaction, the fairy marks a small milestone of growing up – without ever being seen by a child. To the child, it remains uncertain whether the Tooth Fairy is a little elf with wings, Dwayne Johnson or a parent after all…

Years later, we put a coin under our child’s pillow and no longer believe in the guardians of light: Santa Claus, the Easter Bunny and the Tooth Fairy. Yet, dental health becomes especially important when the milk teeth fall out. Anyone who has ever had a toothache knows how it can put a damper on the enjoyment of everyday things.

We should consider ourselves lucky to have dentists who work to prevent and treat dental diseases. In doing so, they use many magical wands in the form of their instruments. In addition to scalers and mirrors, dental rods play a major role. These rigid rods use glass fibers to transfer light from one end to the other.

In the production process, light guide rods can be compressed and shaped into specific, complex geometries. Rigid light guides are available in all shapes, bending angles and cross-sections. Depending on the requirements, they can be individually adapted.

Thanks to this versatility, light guide rods can bring light to the tip of a drill or around the corner to a molar. They can deliver white light to make details visible or blue light to cure plastic dental fillings. Unlike plastic light guide rods or electric light sources, glass light guides are biocompatible and autoclavable. By withstanding temperatures of up to 400°C, they can be easily disinfected. In addition, the glass rods allow more manageable, slimmer instruments for dental treatment.

Of course, the light guide rods used in dentistry are still not quite as magical as the tooth fairy. So, we can understand the desire to keep this mythical creature alive, at least for children.
