Experts from Kunming Kangsheng Stomatological Hospital suggested choosing all-ceramic teeth. All-ceramic teeth have no metal base crown, which effectively avoids the problems of metal allergy and black line and has no toxic and side effects on human health. All-ceramic teeth have good transparency and gloss, and their shapes and colors are more natural and realistic. All-ceramic teeth have no bad metal ion leakage, which does not affect health. And the compressive strength is comparable to that of metal, so don't worry about porcelain collapse.
