What is the main benefit of using a dental dam during treatments?

Using a dental dam during treatments primarily maintains a dry working field, which is essential for various dental procedures. A dry environment helps the dentist achieve better visibility and access to the area being treated. It also prevents saliva and blood from contaminating the work area, which can compromise the quality of dental materials and the overall effectiveness of the procedure. By isolating the tooth or teeth being treated, a dental dam supports better adherence of materials, reduces the likelihood of infections, and enhances the precision of work, ultimately leading to improved outcomes for the patient. This effective isolation contributes significantly to the overall success of dental interventions.
