Dental Bridges

All of your teeth play an important role in speaking, chewing and in maintaining proper alignment of other teeth. Tooth loss doesn’t necessarily have to occur as you age, but if you do lose teeth they must be replaced to maintain proper function of your mouth. Fortunately, there are options for correcting tooth loss.

Benefits of Replacing Missing Teeth with a Dental Bridge

Replacing missing teeth with a bridge offers both functional and aesthetic advantages:

• Restores your ability to chew comfortably
• Improves speech clarity
• Maintains facial shape and support
• Prevents neighbouring teeth from shifting
• Distributes bite forces evenly
• Enhances overall confidence

Early replacement of missing teeth can help prevent long term complications such as jaw joint strain and uneven tooth wear.

Dental Bridge Options

A bridge — a device used to replace missing teeth — attaches artificial teeth to adjacent natural teeth, called abutment teeth. Bridges are either permanently attached (fixed bridges), or they can be removable.

Fixed bridges are applied by either placing crowns on the abutment teeth or by bonding the artificial teeth directly to the abutment teeth. Removable bridges are attached to the teeth with metal clasps or by precision attachments.

If you’re missing one or more teeth, you may be aware of their importance to your appearance and dental health. Your teeth work together for many daily functions from eating to speaking. With missing teeth, it’s difficult to do these things. Missing teeth can and should be replaced. Fixed bridges are a great way to restore your dental health and appearance.

Why do I need a bridge?

Oral functionality and appearance are important reasons for wearing a bridge. A bridge helps support your lips and cheeks. The loss of a back tooth may cause your mouth to sink and your face to look older.

Dental health is the most important reason for a bridge. Teeth were designed to complement each other. Unusual stresses are placed on the gums and other oral tissues when teeth are missing, causing a number of potentially harmful disorders.

Increased risk of gum disease has proven to be one of the worst side effects of missing teeth and can be minimized with a bridge.

Missing teeth can cause speech disorders as they are used to make many of the sounds we use to speak clearly.

How is a bridge attached?

The attachment procedure usually takes two or three appointments to complete. At the first appointment our dentists will prepare the teeth on either side of the gap by removing a portion of the enamel and dentin.

Since the bridge must be fabricated very precisely to ensure correct bite and to match the opposing tooth, impressions of the teeth are taken and sent to a lab where the bridge will be constructed.

Fixed bridges are typically cemented to the natural teeth next to the space left by the missing tooth. A pontic (false tooth) replaces the lost tooth. Crowns, which are cemented onto the natural teeth on either side of the gap, provide support for the bridge. A pontic (false tooth) replaces the lost tooth, restoring both the appearance and function of your smile. Fixed bridges are typically cemented to the natural teeth next to the space left by the missing tooth.

What materials are used?

Bridges can be constructed from gold alloys, non-precious alloys, porcelain, or a combination of these materials. Porcelain is often bonded to either precious or non-precious metal.

How do I take care of my bridge?

A strict regimen of brushing and flossing will keep the bridge and surrounding teeth clean. This is of critical importance as the bridge relies on the neighboring teeth for support.

Signs Your Dental Bridge May Need Attention

A well-maintained dental bridge can last many years, but like any dental restoration, it requires monitoring over time. Knowing the warning signs that your bridge may need professional attention can help you address issues early, before they develop into more serious and costly problems. Here is what to look out for.

1. Pain or Discomfort Around the Bridge

Some sensitivity is normal immediately after a bridge is fitted, but pain or discomfort that develops or persists after the initial adjustment period should not be ignored. Ongoing pain around the bridge, the abutment teeth, or the surrounding gum tissue can indicate decay developing beneath the crown, a loose fitting bridge, or changes to the underlying tooth structure that require prompt assessment.

2. A Loose or Shifting Bridge

A fixed bridge should feel completely stable at all times. If you notice any movement, rocking, or a change in the way the bridge feels when biting or chewing, the cement holding it in place may have weakened or the supporting abutment teeth may have been affected by decay or damage. A loose bridge should be assessed by your dentist as soon as possible, as continued use can cause further damage to the abutment teeth and gum tissue.

3. Sensitivity to Hot, Cold, or Sweet Foods

Increased sensitivity in the area of the bridge can indicate that decay has begun to form on or around the abutment teeth beneath the crowns. Because the natural teeth supporting the bridge are still vulnerable to decay, maintaining a thorough cleaning routine around the bridge is essential. If sensitivity develops suddenly or worsens over time, contact your dentist promptly.

4. Changes in Your Bite

If your bite feels different than usual, or if the bridge feels higher or lower than it should when you close your mouth, this may indicate that the bridge has shifted, worn unevenly, or that the surrounding teeth have moved. An uneven bite places additional stress on the bridge and the neighbouring teeth and should be corrected without delay to prevent longer-term damage.

5. Visible Damage to the Bridge

Inspect your bridge regularly for any visible signs of wear or damage, including chips, cracks, or fractures in the porcelain or material. Even minor damage can compromise the structural integrity of the bridge and, if left untreated, can worsen over time. Do not attempt to repair a damaged bridge at home, as this can make the problem worse and affect the fit.

6. Swelling, Redness, or Bleeding Around the Bridge

Healthy gum tissue around a bridge should appear pink and firm. Swelling, redness, bleeding when brushing, or a receding gum line in the area of the bridge can indicate gum disease or an issue with the fit of the bridge that is allowing plaque to accumulate in difficult-to-clean areas. As noted above, increased risk of gum disease is one of the most serious consequences of missing teeth, and a poorly maintained or ill-fitting bridge can contribute to this risk.

7. Bad Breath or an Unpleasant Taste

Persistent bad breath or an unpleasant taste that does not resolve with regular brushing and flossing can be a sign that food particles and bacteria are becoming trapped beneath or around the bridge. This is often related to a gap forming between the bridge and the gum line, or a breakdown in the cement seal, both of which require professional attention.

When to See Your Dentist

If you notice any of the signs above, do not wait until your next scheduled check-up to seek advice. Early intervention is almost always simpler and less costly than waiting until a problem has progressed.

Frequently Asked Questions

What is a dental bridge? A dental bridge is a device that fills the gap left by one or more missing teeth. Artificial teeth are attached to the natural teeth on either side of the gap (called abutment teeth). Bridges can be fixed (permanently cemented in place) or removable.

Why is it important to replace missing teeth? Missing teeth affect your ability to chew and speak clearly, can cause neighbouring teeth to shift, and place unusual stress on the gums and surrounding tissues. Over time, tooth loss can also change the shape of your face and significantly increase the risk of gum disease.

How is a dental bridge fitted? The process usually takes two or three appointments. At the first visit, the teeth on either side of the gap are prepared and impressions are taken. These are sent to a lab where the bridge is custom-made. At the following appointment, the bridge is cemented into place.

How do I care for my dental bridge? Brush and floss thoroughly every day, paying particular attention to the area around and beneath the bridge. Good oral hygiene is essential, as the bridge relies on the neighbouring teeth for support and those teeth remain vulnerable to decay.

What are the signs that my bridge needs attention? See your dentist if you experience pain or discomfort around the bridge, notice it feeling loose or shifting, develop sensitivity to hot or cold foods, notice changes in your bite, or experience swelling, bleeding gums, or persistent bad breath in the area.
