Over-the-counter Bleaching Products

Aim

The aim is to familiarise practitioners with the range and use of over-the-counter (OTC) products and the problems associated with this approach to bleaching.

Outcome

Practitioners will be more familiar with the appearance issues surrounding the use of unsupervised over-the-counter products.

Introduction

Unsupervised bleaching can be cost-effective for some patients but has certain limitations and drawbacks. Restorations can appear mismatched in shade following such bleaching.

Bleaching Strips

The use of intraoral strips to deliver therapeutic agents or other substances is not new.

These are supplied by a pharmacy or simply purchased in a supermarket without any input or prescription from a dentist.

Bleaching strips are of varying thickness and are available with different concentrations and amounts of bleaching agents. Pre-packaged products are available for maxillary and mandibular teeth. They are available in a variety of shapes, sizes and packaging, usually designed to entice consumers into the popular and lucrative market of tooth bleaching. The sale of over-the-counter bleaching systems represents huge business worldwide. Figs 6-1 to 6-4 give an example of bleaching strips available over-the-counter.
