Good be very effective,under certain circumstances.
I had a molar that broke, just on one corner, and pulled away some of the filling, in that tooth. It wasn’t too serious, nor was it painful. But it left a sharp, jagged surface causing the side of my tongue to become very sore. The repair kit was easy to apply, but I found the surface had a slight “ chalky” feel to it, and not very soothing when my tongue rubbed against it. So I removed it, after 4 hours , and stuck a small piece of chewing gum over the tooth instead. It worked a treat and was much more comfortable. I think it you had serious damage to a tooth, or lost a lot of filling, resulting in pain, then I’m sure the dental kit would be a very good solution.
