If you don't want to grind too many teeth, you can make an ordinary Kouga, so just make a slit in the teeth on both sides. It won't grind too many teeth, but it's too ugly, because the lid is metal, obviously.

In fact, the lower teeth can be seen with one mouth. I still recommend porcelain teeth. Although the teeth on both sides have been worn off, the effect is very good. Porcelain itself is more suitable than Kouga, and there is no gap. Don't worry about tooth decay on both sides.

Dental implants are not recommended. Expensive is one thing. People have to suffer. Why bother?

Removable dentures, because there is only one tooth, have a danger that they will fall off if swallowed, and will break after eating, which is very inconvenient, and you are still young and not suitable for installing this tooth.
