Dental Bridges: What Happens When the Anchor Teeth Decay?

A dental bridge can beautifully restore your smile, filling the space left by a missing tooth and improving your ability to chew and speak. But if either of the teeth supporting that bridge, known as anchor or abutment teeth, start to decay, it’s crucial to know what to do next.

At TLN Family Dental in Houston and Pearland, Texas, our skilled team of dental professionals guides patients in how to care for their bridges and what steps to take if decay occurs beneath them. You won’t have to do any guesswork, our team has you covered.

How a dental bridge works

A traditional dental bridge relies on two healthy teeth on either side of the missing tooth. These teeth are reshaped and fitted with crowns that support the bridge’s artificial tooth (or row of teeth). While this design restores function and appearance, it also means that the long-term health of the anchor teeth is critical to the bridge’s long-term success.

When decay forms beneath the crowns that anchor the bridge, it can compromise the integrity of the entire restoration. Because the crowns completely cover the teeth, early decay can go unnoticed until pain, swelling, or loosening of the bridge occurs.

Why decay develops under a bridge

Even with excellent dental hygiene, plaque and bacteria can accumulate at the margins where the crown meets the natural tooth. This area can be challenging to clean thoroughly. Over time, this trapped bacteria can lead to tooth decay or gum infection beneath the bridge.

Additionally, bridges that are several years old may loosen slightly, creating tiny gaps that allow bacteria to seep in. Poor-fitting bridges, gum recession, or dry mouth (often caused by certain medications) can also increase the risk of decay around anchor teeth.

It is vitally important to maintain good oral hygiene as well as regular dental check ups for exams and cleanings. Bridge work must be cleaned around the abutments and underneath the abutments daily. It is also imperative that we limit sugar and acids from our diet. Both are known to demineralize and decay natural teeth and the margins between the restorations and the natural teeth. 

Signs your anchor teeth might be in trouble

While decay under a crown may go unnoticed its early stages, several warning signs may develop, such as:

• Sensitivity to hot or cold temperatures
• Pain or pressure when biting
• Gum tenderness or swelling around the bridge
• A dark line near the gumline
• Loosening or movement of the bridge itself

If you notice any of these symptoms, it’s important to schedule an evaluation at TLN Family Dental as soon as possible. Early intervention can often preserve the existing bridge and prevent further damage.

Treatment options when anchor teeth decay

The stage of decay determines the treatment approach. In mild cases, your TLN Family Dental provider can carefully remove the bridge, clean out the decay, and restore the teeth with a new bridge. 

However, if the decay is extensive or the anchor tooth can’t be saved, our team may recommend alternative options such as dental implants, or an implant-supported bridge.

Implants and implant-supported bridges eliminate the need to rely on neighboring teeth for support, making them a long-lasting and more decay-resistant option.

How to protect your bridge and anchor teeth

Taking steps to reduce the risk of dental decay is the best way to protect your bridge. Our team at TLN Family Dental recommends:

• Brushing twice a day 
• Flossing daily with special bridge threaders
• Scheduling regular dental check-ups 
• Using an antibacterial mouth rinse 
• Use a fluoridated paste or rinse when needed

A dental bridge can last 10 or more years with proper care. But staying proactive about your oral health is the key to avoiding complications like decay beneath the anchor teeth. Regular dental check-ups are crucial to protect your oral health.
