Dental crowns and bridges are two of the most common solutions for addressing dental issues such as damaged teeth, missing teeth, or severe tooth decay. Both prosthetic devices aim to restore oral health, improve the appearance of teeth, and enhance quality of life. However, understanding the difference between crowns and bridges is essential to making an informed choice about which treatment option is best for you.
Continue reading this article for an in-depth discussion of the two restorative procedures and how they can help you with your dental needs.
Understanding Dental Crowns
A dental crown shields broken or weakened teeth, restoring their original shape, strength, and functionality. Crowns are commonly used on teeth with significant decay, fractures, or root canal treatment. They can also serve a cosmetic purpose, enhancing the appearance of misshapen or discolored teeth.
Crowns are available in porcelain, ceramic, zirconia, gold alloys, and resin. Each type of material offers unique benefits, such as the natural appearance of porcelain or the durability of metal crowns.
Dental Bridges Explained
A dental bridge is a custom-made artificial filler for gaps left by missing teeth. The prosthetic teeth that are secured in place by attaching them to the neighboring teeth. Bridges not only restore your smile but also enhance your ability to chew and help keep surrounding teeth from shifting out of alignment.
There are different types of bridges to suit various needs, such as traditional bridges, cantilever bridges, and resin-bonded bridges. Traditional bridges work by attaching crowns to the teeth on either side of the gap, positioning the artifical tooth in between to fill the space. Cantilever bridges, meanwhile, are an option when there’s only one healthy tooth next to the space, anchoring the artificial tooth to a single side.
Key Differences Between Crowns and Bridges
While both dental crowns and bridges are effective treatments for restoring dental health, they serve different purposes and are used in distinct scenarios. Here’s a breakdown of the key differences between the two:
1. Purpose
Dental crowns and bridges serve distinct purposes in restorative dentistry, each addressing specific dental issues to improve oral health and functionality. A dental crown is designed to repair and protect a single tooth with damage, decay, or weakness. It functions like a protective cap that encases the whole tooth to bring back its original shape, strength, and appearance.
Crowns work well for teeth that have suffered extensive decay, fractures, or undergone root canal treatment. They can also enhance the appearance of misshapen, discolored, or severely worn teeth. By encasing the tooth, a crown provides long-term protection and helps maintain the tooth’s function within the mouth.
A dental bridge, on the other hand, is used to replace multiple missing teeth. It features synthetic teeth secured by crowns on the adjacent teeth, known as abutment teeth. With the gap filled, your teeth will be properly aligned, preventing neighboring teeth from shifting, and restores bite balance.They also help maintain the natural shape of your face, which can sometimes change due to tooth loss.
Beyond functionality, bridges improve the appearance of your smile by seamlessly blending with your natural teeth. Whether you’re missing a single tooth or several teeth in a row, a bridge offers an effective solution to restore both cosmetic appeal and chewing function.
2. Procedure
The dental crown procedure typically involves two sessions. The first session is for preparation of the damaged tooth, and dental impressions are taken to create a custom crown. The dentist will place a temporary filler while the permanent one is prepared in a dental laboratory. You will then have your permanent crown cemented into place when you come back for the second session.
Meanwhile, the bridge procedure also usually requires a prep session and a final one. The abutment teeth will be prepared first, taking impressions, and placing a temporary bridge. The permanent bridge is then created in a dental lab and cemented into place during the second visit.
If the adjacent teeth aren’t healthy enough to support a bridge, your dentist may recommend alternative solutions like dental implants or implant-supported bridges. These options don’t rely on neighboring teeth for support.
3. Materials
Crowns can be made from various materials, including porcelain, ceramic, zirconia, gold alloy, and resin. Each material has its advantages, such as the natural appearance of porcelain crowns or the durability of metal crowns.
Meanwhile, bridges are typically made from similar materials as crowns, including porcelain, ceramic, and metal alloys. To choose the best material, the location of the bridge, aesthetic preferences, and functional requirements are considered.
4. Longevity
With proper care, including regular brushing, flossing, and dental check-ups, a dental crown can last 10-15 years or longer. Dental bridges also last long, typically between five to 15 years, depending on the kind of bridge, the materials used, and the quality of their maintenance.
Artificial teeth, whether a bridge or a crown, can be damaged by habits like teeth grinding or bruxism, chewing on hard objects, or trauma to the mouth. Poor oral hygiene can also lead to decay at the crown’s edges or gum disease, compromising its stability. Additionally, wear and tear over time or using the crown to bite down on extremely hard foods can cause cracks, chips, or loosening, reducing its effectiveness and lifespan.
In some cases, a damaged crown or bridge can be repaired. Minor damage in crowns may be fixed with composite resin, while more severe damage may require replacement. Bridges can also be fixed or replaced if the supporting teeth or the pontic becomes damaged.
5. Cost
The cost of a dental crown varies depending on the type of material used, the complexity of the procedure, and the dental practice. Porcelain and ceramic are usually at a higher price point than metal or resin crowns.
Bridges are generally more expensive than crowns because they involve multiple teeth and a more complex procedure. The cost depends on the type of bridge, the materials used, and the number of missing teeth being replaced.
6. Aesthetic and Functional Outcomes
Crowns are excellent for restoring the appearance and function of a single damaged tooth. They provide a natural-looking smile, and you can find the perfect color that will blend seamlessly with your natural teeth.
Meanwhile, aside from their aesthetic benefits, bridges also improve chewing function and prevent issues like bone loss or shifting of adjacent teeth.
Based on the above factors, the treatment that you need is generally based on the number of teeth missing and what your dentist recommends. If both aren’t viable, there are also alternative procedures to consider.
FAQs
Here are some of the most common questions people ask about dental crowns and bridges:
1. Can dental crowns or bridges be used for front teeth?
Yes, both dental crowns and bridges can be used for front teeth. Porcelain or ceramic crowns are preferred for front teeth due to their natural appearance. Bridges for front teeth are also common, especially when replacing one or more missing teeth to restore aesthetics and function.
2. Are dental crowns or bridges painful to get?
The procedures for both crowns and bridges are typically performed under local anesthesia, so you shouldn’t feel pain during the process. Some patients may feel mild and fleeting discomfort or sensitivity once the anesthesia wears off. They can be easily managed with over-the-counter pain medication.
3. Can I get a crown or bridge if I have gum disease?
Gum disease must be treated before placing a crown or bridge. Untreated gum disease can compromise the stability of the restoration and lead to further complications. Your dentist will assess and address any gum disease before moving forward with a crown or bridge treatment.
4. How do I clean and maintain a dental bridge?
Maintaining a dental bridge requires special attention. To clean effectively, use a floss threader or interdental brush to reach under the pontic (false tooth) and around the supporting abutment teeth. Additionally, consistent brushing and rinsing with an antibacterial mouthwash are crucial to prevent plaque accumulation and reduce the risk of gum disease.
5. Are there any dietary restrictions with crowns or bridges?
While crowns and bridges are durable, it’s best to avoid chewing on extremely hard foods (like ice or hard candy) or sticky foods (like caramel) that could damage the restoration. Maintaining a balanced diet will help prolong their lifespan.
6. Can dental crowns or bridges be whitened?
Many whitening procedures are not advisable for dental crowns and bridges because they’re made from materials like porcelain or ceramic that don’t respond well to whiteners. If you plan to whiten your natural teeth, do so before getting prosthetic teeth to ensure a color match.
7. How long does it take to adjust to a new crown or bridge?
Most patients adjust to a new crown or bridge within a few days to a couple of weeks. You may initially experience slight discomfort or difficulty chewing, but this should subside as you get used to the restoration.
8. Can a crown or bridge improve my speech?
Yes, both crowns and bridges can improve speech, primarily if missing or damaged teeth are affecting your ability to pronounce certain words. Restoring your teeth with these prosthetics can help you speak more clearly and confidently.
9. What happens if I don’t replace a missing tooth with a bridge or crown?
If you have a missing tooth, you may experience shifting of adjacent teeth, bite problems, jawbone loss, and difficulty chewing. A bridge or crown helps prevent these complications by filling the gap and maintaining proper dental alignment.
Conclusion
Dental crowns and bridges are effective restorative dentistry procedures that can benefit oral and general health and boost confidence. Understanding the difference between crowns and bridges, as well as their respective procedures and benefits, will help you make an informed decision about your dental care.
You also need the assistance of experienced dental health practitioners who can guide you through the process. With the proper treatment and diligent care, you can achieve a healthy, natural-looking smile that lasts a lifetime.
