We do, but they have to be screwed in to your jawbone with titanium screws. Natural teeth are glued in place by a layer around the base of the tooth called the periodontal ligament. It acts as a cushion and can heal itself so it doesn't wear out.

The Short Answer

We do, but they have to be screwed in to your jawbone with titanium screws. Natural teeth are glued in place by a layer around the base of the tooth called the periodontal ligament. It acts as a cushion and can heal itself so it doesn't wear out. Tooth implants have no shock absorber or have shock absorbers which eventually wear out. The screws can also work loose… People get implants anyway but it's a last-ditch thing and expensive. You're arguably better off living with dentures. Back when I wanted to do something with my life I was going to invent a bioengineered lab-grown periodontal ligament to solve this exact problem so people could have tooth implants with cushioning but then I went crazy and wound up working menial jobs and commenting on Reddit for the rest of my life.
