I don't agree with the above netizen's idea of making a crown. The crown around the teeth will wear a lot. If the teeth are too small, it is not necessary. In fact, the size and shape of teeth can be adjusted by using thin porcelain veneer.

Moreover, because the veneer is only treated on the side of teeth and lips, it will not affect the side of teeth and tongue, so it has no effect on pronunciation and speech, and it is faster to adapt.
