Crowns & Bridges

If you have one or more missing teeth, your dental professional may recommend that you get artificial replacements. There are removable options like dentures that you can take out and clean, but those can slide around, shift, or fall out – which understandably won't fly for many people. And that's why there are crowns affixed to dental implants and bridges which function more like your actual teeth. But between crown implants and bridges, which option is the best choice for you? We'll break down the similarities, differences, advantages, and disadvantages between these two fixed artificial tooth options so that even if you have a fake tooth or two, you'll have a smile that's as real as can be.

​

What's the Difference Between Dental Crowns and Dental Bridges?

A dental crown can cap an individual's damaged or decaying tooth or be placed on top of a dental implant to replace a missing tooth. Dental implants are metal fixtures, surgically fastened to your jawbone below the gums. These metal implants become anchored to your bone through osseointegration (the bone fuses to the metal). This process provides stable support you can rely on while eating and speaking. According to the Cleveland Clinic, the healing process after getting an implant can take 6-12 weeks. Your dental professional will then place a metal post (or abutment) into your implant, onto which they will mount your crown.

Bridges, on the other hand, are solely used to replace missing teeth. They have two crowns – one on either end – and a bridge of replacement teeth that rest in the area of the gums where there is tooth loss. The crowns at the ends of a bridge can fuse to existing teeth (that need to be filed down by a dental professional to fit correctly), or your dental professional can attach them to dental implants.

Whichever of these replacement tooth options is best for you – they can be vital in maintaining your oral health. Gaps in areas of loss can cause your other teeth to begin rotating or shifting into the empty spaces, resulting in a bad bite. And missing teeth can even lead to gum disease and temporomandibular joint (TMJ) disorders.

​

How do Crowns Work?

When a crown caps a damaged, weak, or decaying tooth, it's generally to help maintain its size, strength, shape, and appearance. If you're missing a tooth, a dental professional will give you a dental implant, on top of which they will place your crown. The American Academy of Implant Dentistry says that 3 million Americans have dental implants, and that number is growing by 500,000 every year.

Your crown will be made from one, or a mixture, of various materials. Gold alloy and other metal alloy options tend to be durable and cost-effective, but they won't look much like your other teeth. Porcelain, acrylic, and ceramic crowns can more closely match your natural teeth. Acrylic and ceramic options are known to be durable. Porcelain is a bit more prone to chipping and damage, but porcelain bonded to a metal shell can increase its strength while maintaining its attractive tooth-like aesthetic.

How do Bridges Work?​

Whereas crowns can repair damaged teeth, a bridge's sole function is to replace one or more missing teeth. For a bridge, your dental professional will place caps on filed-down teeth or dental implants at the outer edges of your area of loss. Replacement teeth (called pontics) span the space between the caps where the teeth are missing.

Just like with dental crowns, you have a choice of materials available to you for your bridge. Your dental professional is in the best position to advise you in your material choice base on your individual needs. However, you'll both want to consider and discuss multiple factors like the visibility of the tooth, the cost, the strength, and how it looks.

​

How are Crowns Made?​

 

If you're getting a crown for a damaged or decayed tooth, your dental professional will make an impression of your bite. From that model, they will be able to determine the best shape for your new tooth. Often, the model for your bite needs to be sent to a lab where they will create your crown, which can take a few weeks. Some dental offices can make crowns in their offices depending on the material you choose and whether they have the required equipment. If your dental professional has CAD/CAM (Computer-Aided Drafting/Computer-Aided Manufacturing) capabilities and you're capping an existing, damaged tooth, you could get your crown in a single dental visit.​

How are Bridges Made?​

 

Before your dental professional can have your bridge made, the teeth at the outer edges of the area of loss will be reduced in size so that your bridge will fit on them properly – unless, of course, they place the bridge on implants. Like with a crown, your dental professional will then take an impression to provide an exact mold for the bridge.

Using this impression, your dental office will either create your bridge in-office or send the model to a dental lab. Your dental professional will use temporary crowns or bridges to cover the prepared teeth while the lab makes your bridge.

​

How Long do Crowns and Bridges Last?

 

Sometimes crowns and bridges can become loose or fall out from the damage caused by chewing hard foods, ice, or other hard objects. Dental disease that causes tooth or bone loss is another reason crowns or bridges may loosen over time.

By practicing good oral hygiene, however, crowns and bridges can last a lifetime. Brush at least twice a day, floss or clean between your teeth with interdental brushes or water flossers at least once a day, and consider using other helpful products like antimicrobial mouth rinses and tongue scrapers. Be sure to see your dental professional for regular cleanings – not only to keep your teeth pearly white and bacteria-free but also to check the health of your crown or your bridge. Whether you and your dentist decide on a crown or a bridge for your replacements, we hope your new teeth make you smile​

Dental Bridge, an Implant or an Implant Bridge?

If you’ve lost a tooth or had to have one extracted, you may need a dental bridge or implant. Your dental professional will help you decide which one’s best for you, but here’s some information that is good to know.

​

What's A Dental Bridge?

A dental bridge is a restorative option your dental professional may suggest if your missing tooth is between two healthy teeth. A dental bridge is made of a false tooth suspended between two crowns that your dentist cements onto your healthy teeth on either side. The porcelain is matched to the color of your surrounding teeth. In short: a dental bridge bridges the gap between your teeth. If you're replacing a tooth or teeth near the back of your mouth, a dental bridge may be the best way to go.

​

What's A Dental Implant?

An implant is a false tooth attached to a titanium post your dental professional inserts into the jawbone. Implants are very natural looking. According to the American Academy of Implant Dentistry, implants also help prevent your jawbone from deteriorating. When teeth fall out or are extracted, the jawbone shrinks over time and changes our face's appearance and smile. An implant is embedded in the jawbone, and using the new tooth to bite and chew stimulates the bone, helping to prevent it from shrinking. Also important to know: if you're replacing a front or more visible tooth, the American Dental Association recommends implants for a more attractive smile.

​

What Are Some Differences Between A Dental Bridge And An Implant?

​​

• Appearance. A dental bridge is more noticeable. Implants look more natural.

• Cost. A dental bridge may be less expensive than an implant.

• Time. You can get a bridge completed in two visits within a few weeks. Completion of an implant takes three to six months.

If you need to replace a tooth, chances are you'll need a dental bridge or an implant. The location of your new tooth, cost, and the time it will take for restoration are all important things to consider. Both options can restore your smile and your confident self. Do your research and talk to your dental professional to determine what's best for you.​
