牙齿缝隙过大可考虑进行正畸矫正和做烤瓷冠。时间比较长一些，具体操作方法如下图：
1、检查门牙中的缝隙的大小，确定用哪种方法进行处理。

2、然后用医用切割机，对门牙进行修整，修成平面。

3、由原来的梯形修成方形，方便下面的处理。

4、再把牙套带上，进行拉紧处理。

5、如果拉紧后缝隙还比较大就进行补牙，用专业的烤瓷进行填缝。

6、修整调理约一个月就可以了，到时间把牙套拆掉即可。

注意事项
1、牙齿矫正，花费的时间比较长，一般在1到2年左右(不包括保持期)。但是矫正出来的效果很好，也不损伤牙齿。
2、选择全瓷烤瓷牙，因为全瓷烤瓷牙没有金属基底，不仅能恢复牙体的形态功能，且抗折力强且颜色、外观逼真，表面光滑，长期使用不会出现黑点及牙龈变色等问题，所需要的时间比较短
