Step 2: Using a tooth conditioner (acid etch) on the effected area for at least 15 seconds, This will make the tooth look like etched glass.
Step 3: Applying a bonding agent on the etched area. This step allows the agent to harden and establish a micromechanical bond with the etched dental surface.
Step 4: Applying the Composite. Applying layers of dental composite will provides the shape of the tooth. Each layer adheres to the bonding agent and help recreate the tooth to its original form.
Step 5: The final step is to shape and polish the composite filling.
