Sore gum around crown
A sore gum beside a crown may come from trapped plaque, a rough or overhanging margin, bite pressure, or infection in the tooth.
The short answer
A sore gum beside a crown may come from trapped plaque, a rough or overhanging margin, bite pressure, or infection in the tooth. Cleaning the area may reduce irritation, but persistent pain needs an examination of the crown, gums, bite, and tooth underneath.
How does a crown meet the gum around the tooth?
A crown covers the visible part of a prepared tooth, while its edge meets the gum near the cervical margin. Plaque can collect there, especially if the margin is bulky or the contact traps food.
Pain on biting can reflect a high bite, a cracked tooth, or pulpal disease rather than gum irritation alone. A dental radiograph may help assess the root and supporting bone.
How can I clean around a sore gum and crown?
Brush along the crown margin and clean under the contact with floss or an interdental brush that fits without force. Rinse with water after food, and avoid chewing hard foods on the sore side until it is checked.
The dentist may polish or replace a defective margin, adjust the occlusion, treat gum inflammation, or address infection in the crowned tooth.
When does soreness beside a crown need dental care?
Seek an appointment if soreness persists, the crown feels high or loose, bleeding continues, or food repeatedly packs beside it. Swelling, fever, or a gum pimple near the crown needs prompt assessment.
What should I ask about my sore gum and crown?
Ask whether the crown margin and bite are contributing, whether the tooth nerve needs testing, and whether imaging is indicated. Ask how to clean the exact contact without injuring the gum.
Frequently asked questions
Should I floss around a crown?
Yes. Clean the crown contact gently with floss or a suitable interdental brush.
Can a crown cause an abscess?
The crowned tooth can develop decay or pulpal infection if disease remains or reaches the tooth through a defect.
