The charge for root canal therapy is mainly based on the number of root canals, and if we observe the number of root canals anatomically, we can judge how many root canals there are according to the number of cusp, which is not very accurate, but it can be roughly calculated. As the name implies, bicuspids generally have two root canals, and the cost of each root canal treatment is about 200 yuan.
Posterior teeth Generally, the upper posterior teeth have three root canals, and the lower posterior teeth may have four. That is to say, the cost of root canal treatment for a lower posterior tooth may be more than 800 yuan.
But you said the word bio-alloy, which is not recommended personally. This word will never appear in the mouth of a professional doctor. There are only 200 nickel-chromium piles, 400 cobalt-chromium piles, 800 fiber piles, 3,000 gold piles and 2,000 all-ceramic zirconia piles.
As for the word "beauty crown", you can be more sure that the place you choose is not a professional place, it is definitely a magnificent plastic surgery institution or a private commercial clinic. Don't choose it. There are two kinds of porcelain crowns: Co-Cr alloy 800 and zirconia 3000.
