Dental cement is a crucial material used to bond crowns, bridges, veneers, and other restorations securely to your natural teeth. While designed for strength and longevity, dental cement can eventually wear down, loosen, or break under pressure, often leaving you with discomfort or an unstable dental restoration.
If you suspect that the cement holding your dental work has failed, taking the right steps quickly can prevent further damage and ensure a safe, comfortable solution.
At McLevin Dental Clinic, we frequently treat patients who experience dental cement failure. This guide will help you understand the signs, what to do immediately, and how to get proper care.
What Is Dental Cement?
Dental cement is an adhesive material used by dentists to bond prosthetic restorations like crowns, bridges, inlays, or orthodontic brackets to the tooth structure. It can be temporary or permanent, depending on the type of procedure and the material used.
Over time, cement can degrade due to pressure from chewing, exposure to moisture, or aging restorations. When this happens, the restoration may loosen, fall out, or cause pain.
Common Causes of Dental Cement Breakdown
Understanding the causes can help you prevent the issue in the future. Some of the most common reasons include:
Chewing hard foods or ice
Bruxism (teeth grinding)
Decay under the crown or bridge
Poor oral hygiene leading to gum recession
Old restorations exceeding their lifespan
Repeated trauma or impact to the area
Whether due to wear or stress, a breakdown in dental cement should be addressed quickly to avoid tooth sensitivity, decay, or complete restoration loss.
Signs That Dental Cement Has Broken Down
ItÂ’s not always immediately obvious that dental cement has failed. Look for the following signs:
A loose crown, bridge, or veneer
Sensitivity to temperature or pressure
Food getting trapped around the restoration
A gap or space where the tooth and crown meet
Unusual movement or clicking when chewing
A fallen or completely detached dental piece
If any of these symptoms are present, contact your dentist promptly. Leaving the tooth exposed can lead to decay, infection, or damage to the remaining structure.
Immediate Steps to Take If Cement Fails
If you suspect that dental cement has broken down or a restoration has come loose, follow these steps:
1. Remove the Restoration (If Detached)
If the crown or bridge has come off completely and is loose in your mouth, gently remove it to avoid accidentally swallowing or damaging it. Store it in a clean container to bring to your dental appointment.
2. Rinse Your Mouth
Rinse with warm salt water to cleanse the area of food particles and bacteria. This will also soothe any irritation caused by the exposed tooth.
3. Avoid Chewing on the Affected Side
Refrain from chewing, biting, or applying pressure to the side where the cement has failed. Doing so may worsen the problem or damage surrounding teeth.
4. Protect the Exposed Tooth (If Necessary)
If the tooth feels sensitive or the edge is sharp, you can use over-the-counter dental wax or temporary filling material to protect it until you can see your dentist. This is especially helpful if the inner part of the tooth is exposed.
5. Do Not Attempt to Re-Cement at Home
While temporary dental cement is available in some pharmacies, attempting to reattach a crown or bridge yourself can lead to misalignment, trapping bacteria, or causing further damage. Always wait for a professional evaluation.
When to Seek Professional Care
Contact McLevin Dental Clinic as soon as possible if:
A crown, bridge, or other restoration has fallen out
You experience persistent sensitivity or pain
There is visible decay or damage under the crown
The restoration feels unstable or uneven
You notice swelling or signs of infection
Even if the restoration seems intact, a compromised seal can allow bacteria to enter and decay the underlying tooth structure.
What Your Dentist Will Do
At McLevin Dental Clinic, we begin with a full examination, including digital X-rays if needed, to determine the condition of the tooth and restoration. Based on the findings, treatment options may include:
Re-Cementation
If the restoration is intact and the tooth structure is healthy, it can usually be cleaned and re-cemented in place during the same appointment.
Repair or Replacement
If the crown, bridge, or veneer is damaged or ill-fitting, a new restoration may be necessary. This involves reshaping the tooth, taking impressions, and fitting a new prosthetic.
Treatment of Underlying Decay
If cement failure has exposed decay or infection beneath the restoration, the area will need to be cleaned and treated before a new restoration is placed.
Preventing Future Cement Failure
While some wear is inevitable, you can take steps to extend the life of your restorations and reduce the risk of cement breakdown:
Practice excellent oral hygiene with regular brushing and flossing
Avoid hard, crunchy, or sticky foods that stress the restoration
Use a nightguard if you grind your teeth at night
Schedule regular dental checkups to monitor the condition of restorations
Address early signs of damage or discomfort promptly
Preventive care and awareness are key to maintaining the strength and longevity of dental restorations.
Final Thoughts
Dental cement plays a vital role in keeping your crowns, bridges, and other restorations securely in place. When it fails, timely action is critical to avoid complications and restore stability. With the right approach and professional care, your dental work can be repaired quickly and effectively.
