So I just watched A Cure For Wellness, and wasn't very impressed by it.
Normally when I watch movies I keep an eye out for plot holes and continuity errors, because it often entertains me more than the movie itself.
Typically such plot holes, etc, are well hidden for the most part, so to my astonishment I found myself surprised to find what I feel as an extremely glaring one in a Cure For Wellness.
The issue, much like the title suggests, is about the fact that Lockhart's tooth seems to magically cure itself (fully reappears with zero damage to the surrounding gumline) towards the end of the movie.
To me, this seems like a major continuity error in the film, especially due to the fact that the teeth pulling is never referred to again. I also find it difficult to believe that the "healing water" or "vitamin elixir of life" could be responsible for such an astonishing and nearly perfect regeneration, especially when a metric for such a healing factor is never provided in the movie.
We can only assume that it let's you live forever. I also find it difficult to believe that his loss of two teeth was merely a delusion or hallucination, because his lack of a teeth lasts for quite a while in the movie, and much of the plot transpires during it.
My question is quite simple. Was the regenerating tooth a movie error, or am I missing something vital that fills in the blank?
