Tooth gem

B2B buyers should prioritize Lead-free Crystal, Swarovski Elements, or 18K Gold/White Gold to ensure biocompatibility. Avoid acrylic or cheap plastic gems as they lack the necessary refractive index and may degrade in the oral environment. Ensure the gems have a foiled back (typically platinum or gold foiling) to enhance reflection and provide a better bonding surface for dental-grade adhesives.

Since these products come into contact with the oral mucosa, they must meet strict safety standards. Look for suppliers who provide FDA registration or CE Marking (Medical Device Class I). Additionally, ensure the materials are compliant with REACH or RoHS to guarantee the absence of toxic heavy metals like lead, cadmium, and nickel, which can cause allergic reactions or systemic toxicity.

If sourcing complete kits, the adhesive must be Medical-grade Light-cured Composite Resin or Glass Ionomer Cement. It is critical that the bonding agent is non-toxic and acid-etch compatible. Buyers should verify the shelf life of these chemicals (usually 12-24 months) and ensure they are stored in UV-protected packaging to prevent premature polymerization during transit.

Professional-grade tooth gems should last between 6 months to 2 years if applied correctly. Request shear bond strength test reports from the supplier. High-quality gems feature a micro-etched base or a specific primer coating that increases the surface area for the resin to grip, preventing the gem from falling off during mastication (chewing).

The biggest risk is Customs Seizure due to the product being classified as a medical device in certain regions (like the US or EU). To mitigate this, ensure your supplier provides accurate HS Codes (typically under 7117.90 for imitation jewelry or 9021.29 for dental fittings) and includes a Material Safety Data Sheet (MSDS) in the shipping documentation.

Request a Pre-shipment Inspection (PSI) and ask for a Gold Supplier audit report. Negotiate a Sample Approval clause where the bulk production must match the chemical composition of the approved sample. For high-volume orders, insist on Batch Testing Reports for every 10,000 units to ensure lead-free compliance remains consistent.

Due to their small size and light weight, Air Express (DHL/FedEx/UPS) is the most economical and secure method. Ensure the supplier uses Anti-static, Vacuum-sealed packaging to prevent the gems from moving during transit, which can scratch the facets or damage the foil backing. Always use Trackable Shipping to ensure transaction security.

Do not rely solely on the supplier's word. Request a Third-party Lab Report from recognized bodies like SGS, Intertek, or TUV. If the supplier is hesitant to provide these, it is a red flag. On Made-in-China.com, look for 'Audited Suppliers' who have already undergone verified on-site inspections of their production facilities.
