Final answer:
Glass ionomer cement’s key advantage is its strong adhesion to hard tooth tissues, which promotes dental health by preventing cavities and reducing the need for dental procedures like fillings and extractions.
Step-by-step explanation:
An advantage of glass ionomer cement is its adhesion to hard tooth tissues. This property is beneficial because it allows the material to firmly bind to the teeth, reducing the possibility of dental restoration failure.
Additionally, by adhering well to tooth surfaces, glass ionomer cement can help prevent cavities and minimize the progression of existing ones, leading to less need for fillings and tooth extractions.
Furthermore, its low solubility contributes to its durable qualities in the oral environment, making it a suitable material for dental restorations.
