After Your Crown or Bridge Has Been Re-Cemented
Your existing crown or bridge has been cleaned and cemented back onto the tooth underneath. This is a different situation from a brand new restoration. The restoration itself is unchanged, so there is no settling-in period for the shape or the shade. What matters now is the cement, and the first day is when it is most vulnerable.
While the Cement Sets
Avoid chewing on the re-cemented tooth for at least one hour, and preferably for the rest of the day.
Dental cement reaches most of its strength within an hour, but continues to harden over the next 24 hours.
Avoid sticky foods such as chewing gum, toffee, caramel, and muesli bars for 24 hours. Sticky foods are the most likely cause of a repeat debond.
Avoid very hard foods such as ice, nuts, and crusty bread for 24 hours.
If local anaesthesia was used, wait until the numbness has completely worn off before eating.
Cleaning Around It
Do not floss the re-cemented tooth for 24 hours.
After that, floss normally but slide the floss out sideways rather than pulling it straight back up through the contact. Pulling upwards can lift the restoration off again.
Under a bridge, continue using superfloss, an interdental brush, or a water flosser as you did before.
Brush normally with a soft-bristled toothbrush. Keeping the margin clean is what protects the tooth underneath.
What You May Notice
Mild sensitivity to cold or pressure for a few days. The underlying tooth was briefly exposed while the restoration was off.
A slight taste from the cement for a short time.
Some gum tenderness where excess cement was cleaned away.
Your bite should feel exactly as it did before. If it does not, contact us.
Why It Came Off, and Preventing a Repeat
A crown or bridge that debonds has usually done so for a reason, and the reason matters more than the re-cementing.
Cement washout over time is the most common and most straightforward cause.
Decay in the tooth beneath the crown reduces the surface the cement can grip. If decay was found, we will have discussed whether the crown can be re-used long term.
Grinding or clenching places repeated shear force on the restoration. If this applies to you, wearing your night guard consistently is the single most useful preventive step.
A short crown or a heavily worn preparation offers less retention, and may eventually need remaking rather than re-cementing.
Re-cementing is sometimes an interim measure rather than a permanent fix. If we advised that the restoration will need replacing, please attend the appointment arranged for that, even if it currently feels secure.
If It Comes Off Again
Keep the crown or bridge safe, clean, and dry, and bring it to your appointment.
Do not attempt to glue it back yourself. Household adhesives are toxic, are not removable, and will usually make a proper repair impossible.
Over-the-counter temporary dental cement is acceptable for short-term use if you cannot be seen immediately, but it is not a substitute for review.
Avoid chewing on the exposed tooth, and keep it clean, as it may be sensitive.
Contact us promptly. An exposed preparation can decay quickly and can drift out of position, which affects how well the restoration fits when it is re-cemented.
What Is Normal During Recovery
Mild cold or pressure sensitivity for a few days
Brief gum tenderness around the margin
A temporary taste from the cement
The restoration feeling entirely normal within a day or two
When to Contact Your Dentist
A bite that feels high or uneven
The restoration feeling loose or shifting again
Pain on biting, or sensitivity that worsens rather than settles
Lingering pain after hot or cold, or pain that wakes you at night
Gum swelling, bleeding, or a bad taste or smell around the restoration
A rough edge or a piece of cement you can feel with your tongue after a few days
If you notice any of these signs, contact ArtSmiles on the Gold Coast for review. Pain on biting after re-cementing should always be checked, as it can indicate decay or a crack in the tooth beneath the restoration.
You can book a consultation online or get in touch with us if you have concerns during your recovery.
