Hydrotherapy with a water jet spray is commonly used in dental practices for various applications, including plaque removal and cleaning. However, it's important to recognize that while the method can effectively assist in cleaning, it has limitations when it comes to certain aspects of dental hygiene.

The statement that it effectively removes plaque is not accurate as the primary mechanism for plaque removal relies on proper brushing and flossing techniques. While hydrotherapy can help dislodge food particles and some superficial debris, it may not be as effective in thoroughly removing established plaque, which is often adherent to tooth surfaces and requires mechanical action, such as brushing, to be effectively removed. Additionally, hydrotherapy focuses more on providing an irrigation effect rather than a strong mechanical action sufficient to eliminate all plaque deposits.

Other statements highlight that hydrotherapy does not harm the gums, is capable of removing debris, and acknowledges that it does not effectively remove the acquired pellicle. The acquired pellicle is a thin film of proteins that forms on teeth and is not readily displaced by water jets, emphasizing the need for other methods in effective oral hygiene practices.
