Is it better to make porcelain teeth, cobalt porcelain teeth or silver porcelain teeth? This is a front tooth. Which one will have beautiful scenery? And it is less irritating to the gums? Cobalt-based ours Co-Cr porcelain is a kind of porcelain teeth with high cost performance. Its metal stability is good, and its irritation to gums is relatively small, but after all, it is made of metal alloy, which is generally not recommended for people who are allergic to metal. Skin-sensitive silver-palladium alloy porcelain can also be used, but silver-palladium alloy porcelain teeth will collapse more easily and metals will turn black more easily, so the cost performance is not as high as that of cobalt-chromium porcelain. If economic conditions permit, it is recommended to choose all-ceramic crown, which will be more beautiful, and there will be no metal to stimulate the gums, and there is no need to consider the impact of porcelain collapse on appearance and use.
