10.3 Patient Comfort Considerations
Reasons for sensitivity
• Incorrect tip placement. Point should be directed
away from root surfaces.
• Allowing the insert to remain in a static position on
the tooth. Keep the tip in motion and change it's
path on the tooth.
• Applying pressure. Use extremely light grasp and
pressure, especially on exposed cementum.
• If sensitivity persists, decrease power setting and/
or move from the sensitive tooth to another and
then return.
