Replacing a Tooth

What's the Difference Between a Dental Bridge and a Dental Implant?

What is used to get across a gap -- a bridge of course! A dental bridge spans the gap between one or more missing teeth giving you a better smile.

Your teeth not only help you chew and speak correctly, but also contribute substantially to your smile and overall appearance (your teeth give form to your face and without them, your facial features can be significantly affected.) If lost teeth are not restored, other teeth often shift, causing crooked teeth, leading to cavities and gum disease. Dental bridges restore potentially compromised oral health to full function.

What Is a Dental Bridge?

A bridge is a special dental appliance used to restore missing teeth. There are several types of bridges used to span the space. The three most common types include:

• Fixed Dental Bridge - This type of bridge is cemented next to the teeth adjacent to the gap, called the "abutment" teeth. A replacement tooth, called a pontic, is attached to crowns that provide added support and cover the abutment teeth. Fixed bridges can only be removed by the dentist.
• Removable Partial Dentures - When the span is large, your dentist may suggest this type of bridge. A removable partial denture fastens to natural teeth with clasps or attachments. This type of appliance can be removed for cleaning and is less expensive than the fixed type. However, it's usually not as durable as the fixed bridge.
• Dental Implant Supported Bridges - When implants have been placed in spaces that have no teeth, they serve as "abutments" or anchors for a bridge.

What Materials Are Used in a Dental Bridge?

An assortment of materials are available depending on the function and appearance. Porcelain, tooth-colored acrylics, gold alloys, and alloys made from non-precious metals all provide important restorative qualities along with making your smile the way you want it.

What's Involved in the Procedure?

Normally at least two visits are needed for preparing the teeth, custom-designing the bridge, and making adjustments for proper fit and comfort.

How Do I Care for My New Dental Bridge?

With bridges, extra care must be given to your gums and teeth. Bridges add more stress to existing teeth and must be supported by healthy gums. Otherwise, these key teeth are susceptible to decay and affect the bridges.

Brushing twice a day and flossing daily along with regular dental visits are essential to good oral hygiene. Flossing is often easier by using floss threaders that help to remove cavity-causing bacteria between the dental bridge and adjacent teeth.

Because bridges are intricate and sometimes difficult to clean, your dentist might suggest a special instrument that helps in caring for your teeth. Similar in design to professional dental cleaning instruments, it's made of tiny filaments that rotate to "swoosh" into the crevices between the teeth and below the gum line. Ask your dentist about this special cleaning device.

With good oral hygiene, a fixed dental bridge can last eight to ten years or more and provide years of service enhancing your smile and appearance and your oral health.

Dental Implant Cost: Three-Unit Bridge v. Single Dental Implant

Tooth implants are considered the ultimate dental restoration solution for tooth replacement, especially when only a single tooth needs to be replaced.

Traditionally, the best dental restoration for a single missing tooth was a three-tooth bridge, better known as a three-unit bridge. This type of missing teeth restoration worked by linking three false teeth together. The middle tooth was used to bridge the gap. Even though this type of dental restoration was considered state-of-the-art for many years, it had its limitations.

For instance, the fabrication of a three-unit bridge required the teeth on both sides of the gap to be whittled down to allow for the false teeth to be slipped over the top of the teeth. Because the three teeth were linked together, they could not be cleaned in the same way as normal teeth. In addition, they required special dental cleaning tools in order to maintain healthy gum tissue.

Today, dental implants are the first choice to replace missing teeth and dental restoration. In the case of a single missing tooth, a tooth implant can be placed by the implant dentist in the jawbone area of the missing tooth. The implant will serve as a replacement for a tooth root and an individual dental crown. The total apparatus is referred to as a single-tooth implant crown.

Once in place, the dental implant crown will look, feel and function like your natural teeth. They are cleaned and flossed just like your natural teeth, and best of all, they do not require any special tools to clean around them, like bridges. Although tooth implants will not decay, they require that you maintain impeccable oral hygiene.

Does a Dental Implant Crown Last Forever?

Even though dental scientists are developing advanced materials to create a more durable crown, the old adage "nothing lasts forever" also applies to dental implant crowns. Because each patient is different, dental implant crowns last a varied amount of time depending on the patient.

Dental crowns that were thought to last only 3 to 5 years can last 10 to 20 years if meticulously cared for. On the other hand, dental crowns that should last for ten or more years can last only two years in a mouth that is neglected.

The dental implant cost factor is hard to determine precisely. The bottom line is that no one can tell you how long a tooth implant will last, but if you take excellent care of your mouth and see your dentist every six months, you stand a better chance of extending the life of your dental implants and other dental restorations.

How Does the Cost of a Dental Implant Crown Compare to a Three-Unit Bridge?

The cost of a three-unit bridge can range from $2,000 to $3,000. The cost of single tooth implants is approximately $3,000. If teeth associated with a dental bridge fail due to recurrent decay or periodontal disease, ordinarily, dental restoration must be done on the entire dental bridge and possibly add a new filling or build-up of the teeth.

The cost of any foundations under a new dental bridge will add to the dental restoration and tooth replacement cost. If and when a dental implant crown has to be reconstructed, most likely, it would be due to the wearing away of the dental crown material.

The only dental restoration cost would be for that of a new dental implant crown and would not incorporate any adjacent teeth. The dental implant cost over your lifetime would be much less than compared to a three-unit bridge, and is the most natural replacement for a missing tooth.
