Cracked Tooth Under a Bridge: Symptoms, Causes, and Treatment Options
A dental bridge is designed to restore the function and appearance of your smile by replacing one or more missing teeth. It typically consists of crowns on the adjacent teeth (abutments) that support a false tooth (pontic) in the gap left by the missing tooth. However, even with this restorative solution in place, underlying issues such as a cracked tooth beneath the bridge can develop, leading to discomfort, pain, and potential complications. Identifying and addressing a cracked tooth under a bridge as early as possible is crucial for preserving your dental health. In this comprehensive guide, we’ll explore the symptoms of a cracked tooth under a bridge, the causes, and the available treatment options.
The teeth that support a bridge (abutment teeth) are critical to the success and longevity of the restoration. These teeth endure the same forces as natural teeth, and if they become damaged, it can compromise the stability of the entire bridge. A crack in one of these teeth is a serious issue that can lead to further complications if not promptly addressed.
A cracked tooth under a bridge may not always be immediately obvious, but several symptoms can indicate that something is wrong. Here are the common signs to watch for:
One of the most common symptoms of a cracked tooth is pain when applying pressure, such as when biting or chewing. The pain may be sharp, sudden, or localized to a specific area under the bridge.
A cracked tooth can lead to increased sensitivity to hot or cold temperatures. You might experience discomfort or pain when consuming hot beverages, cold foods, or even when breathing in cold air.
Pain from a cracked tooth can be intermittent, meaning it comes and goes. You might not feel discomfort all the time, but certain triggers—like biting a certain way or eating specific foods—can cause pain.
If the crack in the tooth has led to an infection or inflammation, you might notice swelling or tenderness in the gums around the bridge. The area may feel sore to the touch or appear red and inflamed.
A cracked tooth under the bridge can compromise the stability of the entire bridge. You might notice that the bridge feels loose or unstable when you bite down or when you run your tongue along it.
A cracked tooth can allow bacteria to enter the tooth and surrounding areas, leading to an infection. This can result in persistent bad breath (halitosis) or a bad taste in your mouth that doesn’t go away with brushing or mouthwash.
Several factors can contribute to the development of a cracked tooth under a dental bridge. Understanding these causes can help you take steps to prevent further damage:
One of the most common causes of a cracked tooth is biting down on something hard, such as ice, hard candy, or nuts. The force exerted on the tooth can cause it to crack, particularly if the tooth is already weakened.
Bruxism, or the habit of grinding or clenching your teeth, can put significant pressure on your teeth, including those supporting a bridge. Over time, this constant grinding can lead to cracks.
Teeth that support a bridge are subjected to daily wear and tear, just like natural teeth. Over time, this wear can weaken the tooth structure, making it more susceptible to cracking.
Teeth that have large fillings or have undergone significant dental work in the past are more prone to cracking. The weakened structure of these teeth may not withstand the pressure placed on them by a bridge.
A sudden impact or trauma to the mouth, such as from a fall, accident, or sports injury, can cause a tooth under a bridge to crack. Even if the bridge itself appears intact, the underlying tooth may have sustained damage.
If you suspect that you have a cracked tooth under your bridge, it’s important to see your dentist as soon as possible. Early diagnosis and treatment can help prevent further damage and complications. Here are the common treatment options:
For minor cracks that don’t extend deep into the tooth, dental bonding might be an option. Bonding involves applying a tooth-colored resin to the cracked area to seal it and restore the tooth’s integrity.
If the crack is more significant but hasn’t reached the tooth’s pulp, your dentist may recommend placing a new crown over the cracked tooth. The crown can protect the tooth from further damage and restore its strength.
If the crack has extended into the tooth’s pulp, causing pain or infection, root canal therapy may be necessary. This procedure removes the damaged pulp, cleans and seals the tooth, and is usually followed by placing a crown.
In cases where the crack is so severe that the tooth cannot be saved, extraction may be the only option. After the tooth is removed, your dentist will discuss options for replacing the tooth, which may include a new bridge or a dental implant.
If the cracked tooth is beyond repair and needs to be extracted, a dental implant may be a viable option. A dental implant involves placing a titanium post into the jawbone, which acts as a replacement tooth root, followed by attaching a crown.
Preventing a cracked tooth under a bridge involves taking care of your oral health and being mindful of habits that could lead to damage. Here are some preventive measures you can take:
Refrain from chewing on hard foods or objects that could crack your teeth, such as ice, hard candy, or popcorn kernels. If you have a habit of biting your nails or using your teeth to open packages, try to break these habits.
If you grind your teeth at night (bruxism) or participate in contact sports, wearing a custom mouthguard can protect your teeth from excessive force and reduce the risk of cracks.
Keep your teeth and gums healthy by brushing twice a day, flossing daily, and using mouthwash. Regular dental check-ups and cleanings are also important for detecting any issues early and maintaining the integrity of your dental bridge.
If you notice any signs of a cracked tooth or other dental issues, don’t wait to see your dentist. Early intervention can prevent more serious complications and preserve your dental bridge.
Q: How can I tell if I have a cracked tooth under my bridge?
A: Symptoms of a cracked tooth under a bridge include pain when biting or chewing, sensitivity to temperature, intermittent pain, swelling in the gums, and a loose or unstable bridge. If you experience any of these symptoms, contact your dentist for an evaluation.
Q: Can a cracked tooth under a bridge be repaired without removing the bridge?
A: Depending on the severity of the crack, your dentist may be able to repair the tooth without removing the bridge, especially if the crack is minor. However, more significant cracks may require removing the bridge to properly treat the tooth.
Q: What happens if a cracked tooth under a bridge is left untreated?
A: If left untreated, a cracked tooth under a bridge can lead to more serious issues, such as infection, tooth loss, or damage to the surrounding teeth and gums. Prompt treatment is important to prevent further complications.
Q: How long can I wait to treat a cracked tooth under a bridge?
A: It’s best to seek treatment for a cracked tooth as soon as possible. Delaying treatment can worsen the crack and increase the risk of complications like infection or the need for extraction.
Q: Can I prevent a cracked tooth under my bridge from getting worse?
A: While you can take steps to prevent further damage by avoiding hard foods and wearing a mouthguard, it’s important to see your dentist for proper treatment to fully address the crack and protect the tooth.
A cracked tooth under a dental bridge is a serious issue that requires prompt attention to prevent further damage and ensure the stability of your bridge. By recognizing the symptoms early and seeking treatment, you can protect your oral health and maintain the function and appearance of your smile.
Preventive measures, such as avoiding hard foods, wearing a mouthguard, and maintaining good oral hygiene, can help reduce the risk of cracks developing in the first place. However, if you do experience any symptoms of a cracked tooth, don’t hesitate to contact your dentist. With the right care and treatment, you can restore the health of your tooth and preserve your dental bridge for years to come.
