The prepared teeth should be fitted with porcelain braces. I regret it. Can I wear metal braces? The big teeth in the back

After root canal therapy, teeth lack blood supply and self-defects, resulting in the lack of crystal structure to support dental arch. The ability of teeth to bear pressure decreases, that is, teeth become brittle and hard objects are easy to bite. The fundamental purpose of crown sleeve is to disperse stress, which many people mistakenly think is to hold teeth to prevent splitting. But all roads lead to the same goal, with the same meaning. Just misinterpreted the principle.

So if you don't make a crown after root canal treatment, you can ensure that you don't eat hard things, but if you eat in a hurry, your teeth won't crack. But this guarantee is difficult to achieve. Once the inevitability and contingency of things collide, problems will arise. So last night, the root canal therapist suggested that the patient should have a crown cover. As for porcelain crowns, they are similar to metal crowns. The thickness difference between metal tube and porcelain crown will be 0.5mm at most, so don't worry about this problem, you can change it to metal crown.
