Final answer:
Tooth polishing, while useful for removing stains and making teeth cosmetically pleasing, has not been shown to significantly enhance dental health beyond plaque and calculus removal, making it arguably nonessential for oral health.
Step-by-step explanation:
The statement that tooth polishing is viewed as a nonessential procedure with limited application can be considered true to some extent. Tooth polishing typically involves the use of abrasives, such as powdered white mica, to remove stains from the surfaces of teeth. While the procedure can result in a cosmetically pleasing appearance due to the removal of stains and the addition of a glittery shimmer, it is important to note that tooth polishing in itself has not been conclusively shown to improve dental health beyond the effects of plaque and calculus removal.
Therefore, in terms of enhancing one's oral health, the key benefits come from the removal of harmful build-up rather than the polishing action itself. However, because it removes stains and can make teeth visually more attractive, many patients and dental professionals consider it a desirable, if not strictly necessary, part of a dental cleaning process.
