What treatment should be avoided due to increased hypersensitivity for certain restorations?

Choosing to avoid acidulated phosphate fluoride in patients with certain restorations is based on the chemical nature of this type of fluoride. Acidulated phosphate fluoride (APF) has a lower pH, which can de-mineralize or etch some types of dental materials, especially when restorations are made from glass ionomer, composite resins, or ceramics. This action can lead to increased sensitivity in the areas surrounding these restorations.

On the other hand, sodium fluoride and stannous fluoride are generally considered safer options for patients with these types of restorations because they do not have the same acidic properties and are less likely to cause potential adverse effects, ensuring that the integrity of the restorations remains intact. Fluoride mouthwash also typically maintains a neutral pH, making it suitable for use with a variety of restoration types.

Thus, avoiding acidulated phosphate fluoride minimizes the risk of exacerbating hypersensitivity and protecting the longevity and efficacy of dental restorations.
