Q: What is the life of the semiconductor?
A: With proper use, almost indefinitely.

A: Titanium dioxide, the metal from which the rod is made, does not dissolve or corrrode in water, so it is perfectly safe.

Q: Will teeth become yellow if toothpaste is not used?
A: Reflecting the dentin color, healthy teeth are naturally off-white in color. Brushing only with water restores their original color. If you must use toothpaste, only a very small amount is recommended.

Q: Is there any proof of the effectiveness of the Soladey?
A: Clinical literature is available from dental colleges in Japan and Canada. According to studies, toothbrushes with semiconductors have proven to be as effective as plaque removing tools.

Q: Can Soladey be used to clean teeth that are not original such as porcelain-fused metal crowns?
A: Yes, Soladey will effectively reduce plaque and provide an anti-bacterial effect even on modified teeth.

Q: Can Soladey be used with braces or a retainer?
A: Soladey will help neutralise bacteria for those using braces. Brush carefully to avoid damaging the materials on the braces. Remove retainers prior to brushing and make sure the retainers have been cleaned before replacing them in the mouth.
