Dental dycal

Dental Dycal is a calcium hydroxide liner placed by a dentist in selected deep cavities to protect the pulp beneath the filling.

Dycal refers to a dental material containing calcium hydroxide. A thin layer may be placed on dentine close to the pulp, the living tissue containing nerves and blood vessels, while a stronger restorative material covers it.

A dentist removes infected dentine, assesses the remaining tooth structure and pulp, then places the liner only where indicated before sealing the tooth with a suitable base and restoration. Do not try to apply a cavity material yourself.

Arrange an examination for pain, sensitivity, a visible cavity or a broken filling. Severe spontaneous pain, swelling, fever or difficulty swallowing can indicate pulpal or spreading infection and needs prompt dental assessment.

Ask how close the decay is to the pulp, whether the pulp appears healthy, which liner or base is planned and what restoration will seal the tooth. Also ask what symptoms would mean that root canal treatment is needed.
