Please let Mei-Shun talk a bit more about her teeth. According to Dr. M’s explanation, any covering except for metals could be cracked if pressed by natural teeth. Occlusion strength does not matter. Therefore, in order to solve Mei-Shun’s problem, another treatment is required to prevent her lower molar from touching its upper counterpart. The former, after shocked twice, must be shaven more to make a slight, indispensable space. Then, the 3rd ceramics would come on it, looking quite better than zirconia.
