Understand the difference between porcelain teeth and porcelain veneers first, and then you will know which kind of teeth to choose for whitening. The main difference between the two is symptoms.
There are answers to the difference between porcelain teeth and veneers:
1. Different materials:

The main porcelain teeth in the market are divided into metal porcelain and all porcelain. All ceramic should be safer and less irritating to teeth, so all ceramic.
The veneers are generally porcelain veneers, whether glass ceramics, cast porcelain veneers or zirconia veneers on the market, all belong to one of the porcelain veneers.
2、 Different degrees of molars during restoration
Both porcelain teeth and porcelain veneers need to grind off the discolored bad teeth, and then use adhesive to stick them to the primary teeth.

Dental veneer is usually used to repair slightly damaged teeth, so the parts that need grinding are better, or even do not need grinding.

Porcelain teeth are grinded according to the degree of tooth damage, and the degree of wear is relatively large.
3、 Different service life:
Porcelain teeth need to be ground off a large number of teeth, and doctors need to be skilled, otherwise it is easy to cause tooth sensitivity and shorten life.
Porcelain veneer: The amount of molars is small, and there is almost no side effect on the teeth after restoration.
3、 The applicability is also different
Porcelain teeth are mainly used to repair: ① Severe tetracycline teeth and dental fluorosis; ② If the teeth are uneven, doctors can choose whether to use porcelain teeth correction according to the situation, which is usually called cosmetic crown correction; ③ There are many tooth defects that need to be protected or repaired.

Dental veneer repair: ①, slightly uneven teeth; ②, black, yellow, medium and light tetracycline teeth; ③ Teeth have gaps; ④ Hope to whiten teeth and restore their beauty.
After seeing the difference, do you think porcelain teeth or porcelain veneers are better for tooth whitening?
Do you know why Xiao Bian said that he should choose the repair method according to the condition of teeth? So when you want to whiten your teeth, it depends on whether you just want to correct your teeth or improve the color of your teeth. Look at whether you have big teeth or yellow teeth. Do you need to whiten them?
