Dental bridges are a common tooth replacement solution that can beautifully restore your teeth and smile. But over time, bridges can develop poor fitting issues that cause it to become unstable. This ill-fitting bridge then fails to properly do its job.
Bridges are custom-crafted from models of your mouth for accurate fitting. But with age and oral changes, even well-fitted bridges can develop issues over 5-15 years of wear. Various factors contribute to bridge misfits, including lost cement seal, natural changes to tooth position, grinding, tooth decay, gum recession, and normal wear.
Detecting signs of an ill-fitting dental bridge is crucial for maintaining oral health and preventing potential risks. Key symptoms, such as looseness, pain, changes in tooth position, poor chewing ability, halitosis, visible gaps, clenching or grinding, recession around the bridge, and tooth decay or erosion, indicate issues that need prompt attention.
Regular dental checkups play a vital role in early issue detection, ensuring the longevity of your bridge. Timely attention to symptoms ensures a refitted bridge, restoring comfort and confidence in your smile.
Signs Your Bridge No Longer Fits Correctly
Symptoms signaling ill-fitting bridge issues include:
A once stable bridge shifting when you bite or chew could indicate lost cement. See your dentist promptly before it fully dislodges.
Any new discomfort, sensitivity or pain in your bridge area, especially when chewing, can signal a defective fit. Have your dentist examine for proper positioning or occlusion.
Changes in Tooth Position
If surrounding teeth begin shifting position, your bridge likely has excess mobility and needs re-cementing or replacing.
Poor Chewing Ability
Difficulty chewing, or food getting stuck or trapped under your bridge warrants an evaluation of the fit.
Bad breath from your bridge area could occur from trapped food debris allowed by a defective seal.
Open spaces between your bridge and gumline or natural teeth mean it is no longer fitting snugly.
Clenching or Grinding
If you notice increased clenching, grinding or chewing on only one side, your bridge may be unstable.
Recession around the Bridge
If your gums appear shrunken or receded around abutment teeth, your bridge could be contributing to further recession.
Tooth Decay or Erosion
Untreated decay around the bridge allows further deterioration, requiring replacement.
What Causes Bridge Misfit?
A variety of issues can alter the stability and fit of a once properly fitting bridge, including:
- Lost cement seal over time
- Natural changes to tooth position and alignment
- Grinding or clenching that strains the cement bonds
- Tooth decay under the bridge abutments
- Gum recession around anchors causing poor fit
- Normal wearing of bridge materials
Dangers of ill-fitting dental bridge
Although dental bridgework are a popular and highly successful tooth replacement option, there is always the danger of issues that necessitate the removal or replacement of a bridge.
Some of the risks that your dentist will discuss with you include:
Tooth Decay in Abutment Teeth
An improper or loose fitting bridge can cause tooth decay to form on the adjacent healthy teeth beneath the crowns. These teeth are more susceptible to decay because the dentist must file down the natural teeth adjacent to the gap in order to implant the crown. Decay in the supporting teeth can in turn lead to tooth injury and bridge instability.
Damage to Adjoining Teeth
Dental bridges can develop rough spots over time. These rough patches can wear away natural tooth enamel on healthy teeth if they come into contact with adjacent teeth.
Gum disease risk is increased
Tooth appliances, such as a dental bridge, can make you more susceptible to gum disease. But this risk can be greatly reduced by practicing proper oral hygiene practices at home, including flossing and brushing your teeth on a regular basis, as well as getting regular dental cleanings. Regular dental appointments enable your dentist to detect any early signs of gum disease and treat it before it causes permanent damage.
Fractures to the pontic or crowns
Although these dental appliances are fabricated from strong dental materials, and can sustain chewing forces as good as your natural tooth enamel, they can still be fragile. Chewing or biting on hard foods can crack or fracture the surface, create a chip, or completely damage the bridge. Though your dentist can repair small chips and cracks, larger fractures may require bridge replacement.
Seeking Adjustment of an Ill-Fitting Bridge
Don’t ignore symptoms of a defective bridge. An expert evaluation by your dentist is needed to determine why your bridge no longer fits optimally. They will examine for:
- Bridge mobility indicating lost cement
- Damage or wear to bridge materials
- Shifting or inflammation in surrounding teeth/gums
- Decay or fractures under the bridge
Repair Options for an Ill-Fitting Bridge
Based on your dentist’s findings, options for restoring proper bridge fit include:
- Bridge removal, cleaning, and recementing – This simple fix works if no extensive damage is found.
- Crown or bridge repair – Small gaps, chips or cracks can often be repaired.
- Crown replacement on abutment teeth – Sometimes only one or a few supporting crowns need replacing.
- Full bridge replacement – If damage is beyond repair or abutment teeth compromised, a full custom replacement bridge may be necessary.
- Implant-supported replacement bridge – Dental implants provide the most secure anchoring for replacement bridges.
With routine dental checkups, issues like tooth grinding or decay can be caught early before straining your bridge fitting. But even well-cared for bridges eventually decline. Stay alert for any symptoms of a loose, painful or poorly functioning bridge which signals the need for repair or replacement. Addressing problems early provides the best chance of correcting the bridge fit for extended use.
Don’t Wait with an Ill-Fitting Bridge
An unstable, painful or non-functional bridge that no longer fits properly requires prompt attention to avoid damage to supporting teeth. Call your dentist as soon as you suspect your dental bridge needs adjustment. Getting realignment or replacement in a timely manner allows for a refitted bridge to provide many more years of service.
Consulting a dental professional at the first signs of issues can help catch small problems before they turn into extensive, expensive repairs. Don’t wait to restore the comfort and confidence of your healthy, natural looking smile.
