The dental bridge procedure is a restorative treatment used to replace one or more missing teeth with a fixed prosthetic restoration. A bridge usually consists of an artificial tooth, called a pontic, supported by neighbouring natural teeth or dental implants.
For a conventional tooth-supported bridge, treatment commonly involves preparing the abutment teeth, taking impressions or digital scans, placing a temporary bridge and later fitting the permanent restoration. The exact dental bridge process depends on the type of bridge, location of the missing tooth and condition of the surrounding teeth.
Getting a dental bridge is not simply a matter of filling an empty space. The dentist must first determine whether the supporting teeth and gums are healthy enough to support the restoration and whether another tooth replacement option may be more appropriate.
Key Takeaways
The dental bridge treatment process usually takes place over several stages rather than being completed in a single step. Important points include:
- The dentist first assesses the missing-tooth area and potential supporting teeth.
- Traditional bridges usually require preparation of the abutment teeth.
- Impressions or digital scans are used to design the permanent bridge.
- A temporary bridge may protect the prepared teeth while the final restoration is made.
- The permanent bridge is checked for fit, bite and appearance before cementation.
- Cleaning around and underneath the bridge is necessary after treatment.
- The exact procedure differs for traditional, Maryland and implant-supported bridges.
The treatment plan should therefore be based on the bridge design and the health of the teeth and tissues supporting it.
What Is a Dental Bridge?
A dental bridge is a fixed dental restoration used to replace missing teeth by spanning the space between supporting teeth or implants. The artificial tooth within the gap is known as the pontic, while the structures supporting the bridge are called abutments.
In a traditional dental bridge, the abutment teeth are usually prepared to receive crowns. These crowns are joined to the pontic, creating a connected restoration.
The bridge is fixed in place and cannot normally be removed by the patient.
Different bridge designs are available. These can include traditional bridges, cantilever bridges, Maryland or resin-bonded bridges and implant-supported bridges.
Because each design obtains support differently, the dental bridge procedure is not identical for every patient.
Who Needs a Dental Bridge?
A dental bridge may be considered for a patient who has one or more missing teeth and wants a fixed replacement. Suitability depends on the number and position of missing teeth and the condition of the surrounding oral structures.
The dentist needs to assess whether there are suitable teeth or implants available to support the restoration.
A bridge may be appropriate when:
- One or more teeth are missing.
- Suitable neighbouring teeth can support a conventional bridge.
- A fixed restoration is preferred over a removable option.
- The missing-tooth space can be restored with an appropriate bridge design.
- The gums and supporting tissues are sufficiently healthy.
A traditional bridge may be particularly relevant when the adjacent teeth already require crowns because of large restorations or structural damage.
If neighbouring teeth are healthy and unrestored, other options such as an implant-supported restoration or resin-bonded bridge may also be discussed depending on the case.
What Happens Before the Dental Bridge Procedure?
Before bridge treatment begins, the dentist assesses the missing-tooth space, bite, neighbouring teeth and gum health. The purpose is to establish whether a bridge is appropriate and which type provides suitable support.
Dental imaging may be used to evaluate the supporting teeth and surrounding bone.
The dentist also checks for conditions such as tooth decay, gum disease, cracks or problems affecting existing restorations. Any active dental disease generally needs to be addressed before the final bridge is fitted.
If an abutment tooth requires restorative or endodontic treatment, this can influence both the timing and design of the bridge.
The planning stage is therefore important because the long-term performance of the restoration depends heavily on the condition of the structures supporting it.
Step-by-Step Dental Bridge Procedure
The conventional dental bridge procedure generally involves assessment, preparation of the abutment teeth, recording their shape, temporary protection and final placement of the bridge.
Step 1: Examination and Treatment Planning
The first stage is determining whether a dental bridge is appropriate for the missing-tooth space.
The dentist examines the teeth beside the gap and assesses whether they can function as abutments. Their structural condition, existing restorations and gum support are relevant.
The bite is also considered because chewing forces will be transferred through the bridge and supporting teeth.
The dentist can then explain the recommended bridge design and any alternatives.
This planning stage should take place before substantial tooth preparation begins.
Step 2: Preparing the Abutment Teeth
For a traditional dental bridge, the natural teeth beside the gap are usually reshaped so that crowns can fit over them. These teeth become the abutments supporting the restoration.
Local anaesthesia may be used during tooth preparation to keep the procedure comfortable.
A controlled amount of enamel and other tooth structure is removed to create sufficient space for the restorative material.
The amount of preparation depends on the crown design and material.
Tooth preparation is irreversible, which is one reason the condition of the neighbouring teeth should be considered carefully before selecting a conventional bridge.
Step 3: Taking an Impression or Digital Scan
After tooth preparation, the shape and position of the prepared teeth need to be recorded accurately. This allows the permanent bridge to be designed to fit the abutments and missing-tooth space.
The dentist may use conventional dental impression materials or a digital scanner depending on the clinical workflow.
The record captures the prepared teeth, neighbouring teeth and surrounding oral structures.
The opposing teeth may also need to be recorded so the laboratory can design a restoration that fits appropriately within the patient’s bite.
The information is then used to fabricate the permanent bridge.
Step 4: Selecting the Appearance of the Bridge
The colour and appearance of a visible dental bridge may be matched to the surrounding natural teeth where appropriate.
The restorative material and location of the bridge influence how aesthetic decisions are made.
Front teeth usually require particular attention to tooth shape, shade and visible contours.
Back teeth must also withstand substantial chewing forces.
The final design therefore balances function, fit and appearance rather than considering colour alone.
Step 5: Placing a Temporary Bridge
A temporary bridge may be placed after tooth preparation while the permanent restoration is being fabricated.
The temporary restoration helps protect the prepared abutment teeth and maintain the appearance and function of the missing-tooth area.
Temporary materials are intended for short-term use rather than long-term chewing.
Patients may therefore be advised to avoid particularly hard or sticky foods that could loosen or fracture the temporary bridge.
Cleaning remains important, although the dentist may recommend specific flossing techniques to avoid accidentally dislodging the restoration.
If a temporary bridge becomes loose or falls out, the dental clinic should be contacted rather than leaving the prepared teeth exposed.
Step 6: Fabricating the Permanent Dental Bridge
The permanent bridge is designed using the records obtained during the preparation appointment.
The restoration needs to fit accurately over the abutment teeth while creating an appropriate artificial tooth within the missing-tooth space.
The pontic should also be shaped so the area beneath it can be cleaned appropriately after treatment.
Different materials may be used depending on the clinical requirements.
Fabrication time varies according to the bridge and dental laboratory workflow.
During this period, the patient normally continues using the temporary restoration.
Step 7: Removing the Temporary Bridge
At the fitting appointment, the temporary bridge is carefully removed so the prepared teeth can be evaluated.
The dentist cleans the abutment teeth and checks for any changes before trying in the permanent bridge.
The new bridge is then positioned to assess how it seats over the supporting teeth.
This stage allows fit problems to be identified before the restoration is permanently cemented.
The bridge should sit appropriately without gaps or obvious rocking.
Step 8: Checking the Fit and Bite
The permanent bridge needs to fit both the prepared teeth and the patient’s bite before final placement.
The dentist checks the crown margins and contacts with neighbouring teeth.
The way the bridge meets the opposing teeth during biting and chewing is also assessed.
An excessively high contact can create discomfort or additional stress on the restoration and supporting teeth.
Minor adjustments may therefore be made before the bridge is definitively cemented.
The patient may also be asked how the restoration feels when biting gently.
Step 9: Cementing the Permanent Bridge
Once the fit, bite and appearance are considered satisfactory, the permanent bridge is secured to the supporting teeth using appropriate dental cement.
The restoration then functions as a fixed replacement for the missing tooth or teeth.
Excess cement around the margins needs to be carefully removed.
The patient can receive instructions about cleaning, eating and what sensations to expect after treatment.
Because the bridge is fixed, maintaining hygiene underneath the pontic becomes an ongoing part of daily care.
Does the Procedure Differ for a Maryland Bridge?
A Maryland or resin-bonded bridge requires a different preparation process because it uses wings bonded to neighbouring teeth rather than full crowns.
This usually means substantially less natural tooth structure needs to be removed.
The supporting surfaces are prepared according to the bridge design, and impressions or digital scans are taken.
The finished bridge is then bonded to the selected tooth surfaces.
This design is commonly considered in selected situations, particularly for some missing front teeth.
The suitability depends on bite, available enamel and the location of the missing tooth.
Does an Implant-Supported Bridge Follow the Same Process?
An implant-supported bridge follows a different treatment pathway because dental implants rather than natural abutment teeth support the restoration.
Implants are first surgically placed within the jawbone.
A period of healing is generally required so the implants can integrate with the surrounding bone.
Once appropriate healing has occurred, prosthetic components are used to support the bridge.
This treatment pathway is generally longer than a conventional tooth-supported bridge because it includes surgical and biological healing stages.
The number and position of implants depend on the missing teeth, available bone and restorative plan.
Recovery After Dental Bridge Treatment
Recovery after a conventional dental bridge procedure is usually focused on adaptation of the prepared teeth, gums and bite rather than surgical healing.
Some temporary sensitivity can occur following tooth preparation, particularly if the teeth remain vital.
The gums may also feel mildly tender after dental procedures around the bridge margins.
Patients should follow individual instructions regarding eating and oral hygiene.
Once the permanent bridge is fitted, chewing may feel slightly different initially as the mouth adapts to the restoration.
Persistent pain, significant temperature sensitivity or an uncomfortable bite should be assessed rather than assumed to be normal long-term symptoms.
How Should You Clean a New Dental Bridge?
A dental bridge needs daily cleaning around the crowns, gum margins and underneath the pontic. Although the artificial tooth cannot develop decay, the supporting natural teeth can.
Regular brushing should clean the visible surfaces and restoration margins.
The area beneath the pontic requires additional attention because conventional floss cannot simply pass down between the connected bridge units.
Cleaning aids may include:
- Floss threaders
- Super floss or similar bridge-cleaning floss
- Interdental brushes where appropriate
- Other cleaning devices recommended by the dentist or hygienist
Plaque control is particularly important around abutment teeth because their health directly affects the stability of the entire bridge.
What Can Affect the Success of a Dental Bridge?
The long-term function of a bridge depends on the restoration itself and the health of its supporting structures.
Good oral hygiene helps reduce the risk of decay around abutment crowns and gum disease.
Biting forces are another consideration. Grinding, clenching and regularly chewing extremely hard objects can place additional stress on a bridge.
The supporting teeth must also remain structurally healthy.
A crack, decay or pulp problem involving one abutment can sometimes affect the entire restoration.
Regular dental assessments allow the bridge and supporting teeth to be monitored over time.
Frequently Asked Questions (FAQs)
How many appointments does a dental bridge procedure require?
A conventional bridge commonly requires more than one appointment because the supporting teeth are prepared before the permanent restoration is fabricated and fitted. The exact number of visits depends on the bridge type and individual treatment requirements.
Does getting a dental bridge hurt?
Local anaesthesia can be used during tooth preparation to minimise discomfort. Some temporary sensitivity or gum tenderness may occur afterwards, but persistent or severe symptoms should be assessed.
Do teeth need to be filed down for a dental bridge?
Traditional tooth-supported bridges generally require preparation of the abutment teeth so crowns can fit over them. Maryland bridges use a more conservative bonded design and may require substantially less tooth preparation.
Do you get a temporary bridge?
A temporary bridge is commonly used during conventional treatment to protect prepared teeth while the permanent restoration is being fabricated. The exact approach depends on the bridge design.
Can I eat normally after getting a bridge?
Eating recommendations can differ between temporary and permanent restorations. Patients are commonly advised to protect temporary bridges from hard or sticky foods, while normal chewing can generally be resumed progressively after the permanent bridge has been fitted appropriately.
What happens if an abutment tooth needs a root canal?
If a supporting tooth develops irreversible pulp inflammation or infection, root canal treatment may be required. The approach depends on whether treatment can be performed through the existing restoration or whether bridge removal or replacement is necessary.
From Missing Tooth to Fixed Restoration
The dental bridge procedure involves more than fabricating an artificial tooth for an empty space. Successful treatment begins with assessing the neighbouring teeth, gums and bite to determine whether a bridge is appropriate and which design should be used.
For a traditional bridge, the process generally includes preparing the abutment teeth, taking impressions or digital scans, providing temporary protection and fitting the permanent restoration after its fit and bite have been evaluated.
The treatment does not end once the bridge is cemented. Daily cleaning around and beneath the restoration and ongoing care of the supporting teeth are important for maintaining the bridge over time.
