When a crown comes away, the prepared tooth underneath may feel unfamiliar, sensitive or difficult to chew on. Finding the crown is helpful, but do not assume it can simply be pushed back into place. At Rotherholme Dental, we check both the restoration and the remaining tooth to understand why it loosened. Contact our Ashby-de-la-Zouch team and explain whether the crown is still partly attached, whether you have pain and whether a post has come out with it. Bring the crown in a clean container. The emergency assessment helps us plan immediate protection and decide whether the existing crown remains suitable.
Causes and contributing factors
Crown cement can weaken, but loss of retention can also be linked to decay, a fracture or changes in the tooth beneath it. Hard or sticky food may dislodge a restoration that was already vulnerable. Grinding and clenching can place repeated stress on a crown or its supporting tooth. A fractured tooth under a restoration needs a different approach from an intact tooth with failed cement. Sometimes what appears to be a crown is a large filling or onlay that has come loose. We assess the remaining structure and the bite before recommending re-cementation, repair or replacement; the restoration cannot always be reused.
Symptoms and when to seek help
An uncovered tooth may react to cold air, drinks or sweet food, while a partly loose crown can feel unstable on biting. A sharp edge, bad taste or ongoing pain beneath a crown may indicate an additional problem. Tell us about swelling around the affected tooth, bleeding, a broken post or a crown on an implant, as this changes the assessment. Do not keep wearing a loose crown that could detach and be swallowed or inhaled. If you develop sudden breathing difficulty after a restoration disappears, seek emergency medical help. Sensitivity without swelling still warrants dental advice because the tooth needs protection and its condition needs checking.
Assessment and treatment options
If the crown is intact, fits correctly and the tooth is healthy enough, cleaning and re-cementation may be an option. Where decay or breakage is present, that needs assessment before a replacement restoration can be planned. A temporary dressing or filling may protect exposed tooth tissue at the emergency visit; a new crown can require further appointments. A tooth with pulp damage may need root canal treatment before restoration. If too little sound tooth remains, removal and replacement options may need discussion. Permanent crowns, re-cementation and other definitive treatment are quoted separately where applicable; the £160 appointment covers the stated emergency assessment and clinically needed inclusions.
Recovery and prevention
While waiting for care, brush gently around the tooth and avoid chewing hard or sticky food on that side. After a crown is fitted, follow the advice on cement setting and contact us if the bite feels high or the crown moves. Cleaning around its margins and between teeth helps reduce decay risk, but a crown does not make the tooth immune to disease. Keep regular review appointments and mention any new bad taste, soreness or food trapping. If you grind your teeth, discuss whether a suitable protective appliance is needed. Never use household adhesive to retain a crown, as it can damage the restoration and irritate tissue.
