Dentists prevent tooth decay using a number of tools and procedures, including dental sealants. These thin, plastic coverings are applied to the chewing surfaces of a patient’s back teeth. The materials used in the dental sealants harden over time, protecting the teeth from future decay, which can result in complex and costly drilling and filling procedures.
The painless application of dental sealants is done in six steps. First, the dentist begins by cleaning any teeth to be sealed. After cleaning, the teeth are dried and swathed in cotton in order to keep them dry throughout the application. During the third phase, the dentist applies a primer solution. After the primer has been placed, the teeth are rinsed and dried once more. Next, the dentist applies the liquid sealant. The sealant hardens within seconds, and the process is finished.
