Counseling on braces for cavities (urgent)

First of all, it depends on whether you have front or back teeth.

If it is a front tooth, you can choose all-ceramic or porcelain, all-ceramic aesthetics is the best, but the most expensive. There are also a variety of metal porcelain, of which pure titanium is more common, does not affect the future to do nuclear magnetism and other projects, other kinds of need to do these checks when the denture removed. In terms of price, there is also titanium porcelain, cobalt chromium porcelain, and nickel-coated porcelain. However, the latter two are not recommended because they contain traces of nickel metal, which is harmful to the body. You can choose between all-ceramic, pure titanium porcelain and titanium alloy porcelain.

If it is a posterior tooth, all-ceramic will chip under the pressure of chewing. If you don't require much for aesthetics, you can do metal, that is, it will have a metallic color. But considering that you are younger and should have higher aesthetic requirements, you can choose between pure titanium porcelain and titanium alloy porcelain.
