Abstract

Abstract: Our professional understanding of the causes and treatment options for dentine hypersensitivity should now allow the dental profession to manage this condition reliably. This paper reviews the aetiology and explains the scientific basis for what has become a confusing number of products and methods available to patients and dental clinicians.

Clinical Relevance: Dentine hypersensitivity appears to be an increasing problem for patients and the dental profession alike. Clinicians need to have up-to-date knowledge of this condition and the products available to treat patients presenting with this troublesome complaint.

Article

Every dentist will be aware of the recent increase in advertising for toothpastes to treat sensitive teeth. There are also a confusing number of products from which patients can choose (Figure 1). The wide range of treatment options available for dentine hypersensitivity indicates that there are many methods for managing this condition.

This paper reviews our current knowledge of dentine hypersensitivity (DHS) and describes the most commonly available products and treatment options.

Dentine is a naturally sensitive tissue. When an otherwise harmless stimulus contacts freshly cut dentine, pain may be experienced. Historically, numerous attempts have been made either to reduce or eliminate this pain, by treating teeth with a wide variety of chemical remedies. These were generally unreliable, therefore operative dentistry continued to be very unpleasant. Fortunately, as local anaesthetic use became more common, the need for a desensitizing agent became less relevant. However, as dental health has improved and more people retain more teeth later in life, there has been an increasing need for a method to desensitize exposed dentine in otherwise healthy teeth.
