Being told that you need a dental filling can raise several questions. How much of the tooth will be removed? Will it hurt? What material will be used? Why does the dentist use a curing light? And why might the tooth feel different afterward?
A dental filling is more than simply placing material into a hole in a tooth. The procedure involves removing compromised tooth structure, preparing the remaining tooth, creating a bond between the tooth and restorative material, and carefully shaping the restoration so it functions with your bite.
Modern tooth-colored composite fillings can restore selected teeth while closely matching the appearance of natural tooth structure.
At Pacha & Bijan Dental in Maitland, FL, the appropriate filling material and treatment approach depend on the location and condition of the tooth, the amount of tooth structure affected, and the patient's individual needs.
What Is a Dental Filling?
A dental filling is a restoration used to replace tooth structure that has been lost or damaged.
When a tooth has a cavity or localized structural defect, the dentist removes the affected material and restores the resulting space with a dental material.
One commonly used option is composite resin.
Composite resin consists of a resin matrix combined with microscopic filler particles. It can be selected in different shades and manipulated directly on the tooth.
When properly placed, the material restores the shape and function of the affected area.
Why Does a Dentist Need to Remove Damaged Tooth Structure?
A filling cannot simply be placed over compromised tooth structure without first addressing the affected area.
The dentist needs to remove the diseased or otherwise unsound material and create a clean, stable surface for the restoration.
The amount removed depends on the size and location of the affected area.
Modern restorative dentistry generally emphasizes conserving healthy tooth structure whenever clinically appropriate.
This means the objective is not to remove as much of the tooth as possible. The goal is to remove the affected structure while preserving the sound tooth that remains.
Step 1: Examining the Tooth
Before placing a filling, your dentist first evaluates the tooth.
This may include:
- Visual examination
- Dental instruments
- Assessment of the tooth's structure
- Evaluation of existing restorations
- Bite assessment
- Dental X-rays when clinically appropriate
The dentist determines the extent of the problem and whether a filling is actually the appropriate restoration.
Not every damaged tooth can be treated with a filling.
If a tooth has extensive structural loss, a different restoration may be necessary.
Step 2: Selecting the Appropriate Shade
For visible teeth, composite resin can be selected to coordinate with the natural tooth.
Shade selection is particularly important for restorations involving front teeth or highly visible areas.
Your dentist considers the appearance of the surrounding tooth structure before selecting the material.
This helps the restoration blend into the existing smile.
Step 3: Numbing the Tooth
If necessary, local anesthesia is used to numb the tooth and surrounding tissues.
The amount of anesthesia required depends on the depth and location of the treatment.
For deeper restorations, adequate anesthesia helps keep the procedure comfortable while the dentist works on the affected tooth.
You may feel pressure or vibration during treatment, but sharp pain should be addressed with additional anesthesia when necessary.
Step 4: Isolating the Tooth
Keeping the tooth clean and relatively dry is important when placing a composite restoration.
Saliva and moisture can interfere with certain adhesive procedures.
Your dental team may use cotton rolls, suction, isolation devices, or other techniques to control moisture around the tooth.
Good isolation allows the dentist to work with greater control during the bonding process.
Step 5: Removing the Affected Tooth Structure
The dentist carefully removes the damaged portion of the tooth.
The exact technique depends on the location and extent of the problem.
The dentist aims to remove the compromised structure while preserving as much healthy tooth as possible.
Once the affected material has been removed, the dentist evaluates the remaining tooth to determine whether it is suitable for restoration.
Step 6: Preparing the Tooth Surface
Before composite resin can be bonded to the tooth, the surface must be appropriately prepared.
For many composite restoration techniques, the enamel and dentin are conditioned using an etching and adhesive system.
The preparation creates an appropriate surface for the bonding process.
This step is important because composite fillings rely on adhesion to the tooth rather than simply sitting inside the prepared area.
Step 7: Applying the Bonding Agent
A dental adhesive is applied to the prepared tooth.
The adhesive creates an interface between the natural tooth structure and composite resin.
The specific adhesive technique can vary depending on the material and clinical approach used by the dentist.
Proper application helps establish the bond necessary for the restoration.
Step 8: Placing the Composite Resin
The composite resin is then placed into the prepared area.
Rather than filling the entire space with one large amount of material, dentists may place composite in controlled increments.
This allows the dentist to:
- Reproduce the tooth's anatomy
- Control the shape
- Adapt the material to the cavity
- Manage curing
- Create appropriate contacts
- Refine the final restoration
The material is carefully sculpted to resemble the original shape of the tooth.
Step 9: Curing the Composite
Composite resin is hardened using a specialized dental curing light.
The light activates photoinitiators within the material, initiating the chemical reaction that converts the resin into a hardened restoration.
The dentist may cure individual increments as they are placed.
This allows the restoration to be built gradually while maintaining control over the material.
Step 10: Shaping the Restoration
Once the composite has been cured, the dentist refines its shape.
This is an important step because the filling needs to function as part of the tooth rather than simply occupy the space left by the damaged structure.
The dentist may adjust:
- Tooth contours
- Ridges
- Grooves
- Contact areas
- Margins
- Overall shape
For back teeth, the anatomy of the chewing surface is particularly important.
Step 11: Checking the Bite
After the restoration has been shaped, your dentist checks your bite.
You may be asked to gently bite down on an articulating material that identifies areas where the teeth contact.
If the filling is too high, it can interfere with your normal bite.
Your dentist can make small adjustments to ensure that the restoration fits appropriately within your existing occlusion.
Step 12: Polishing the Filling
The final stage involves smoothing and polishing the restoration.
A properly polished composite surface can provide a more natural appearance and a smoother surface for routine oral hygiene.
The dentist also checks the margins and surrounding tooth structure before completing the procedure.
Why Does a Filling Sometimes Feel Sensitive Afterwards?
Some patients experience temporary sensitivity following a filling.
The tooth may react to:
- Cold
- Pressure
- Biting
- Temperature changes
Sensitivity can occur because the tooth has undergone treatment and the tissues inside and around it may need time to settle.
The extent and duration of sensitivity depend on factors such as the depth of the restoration and the original condition of the tooth.
If sensitivity is severe, persistent, or worsening, contact your dentist for an evaluation.
What Happens If the Filling Feels Too High?
One common reason a newly restored tooth may feel uncomfortable when biting is an uneven occlusion.
If the restoration is slightly higher than the surrounding teeth, it may receive excessive contact during chewing.
This does not necessarily mean the filling has failed.
Your dentist can evaluate the bite and make an appropriate adjustment when necessary.
Do not attempt to modify the filling yourself.
How Long Does a Dental Filling Take?
Treatment time depends on several factors, including:
- Number of teeth being treated
- Size of the restoration
- Location of the tooth
- Depth of the affected area
- Complexity of the restoration
- Patient-specific circumstances
A small composite restoration may be completed relatively quickly, while a larger or more complex restoration can require additional time.
Your dentist can provide a more specific estimate during your appointment.
How Long Does a Composite Filling Last?
Composite fillings are designed for long-term use, but they do not last indefinitely.
Their lifespan can be influenced by:
- Size of the restoration
- Tooth location
- Bite forces
- Oral hygiene
- Teeth grinding or clenching
- Diet and habits
- General dental care
A large filling on a heavily loaded back tooth may experience different forces than a small restoration on a front tooth.
Regular dental examinations allow your dentist to monitor the filling and the surrounding tooth.
Can an Old Filling Need to Be Replaced?
Yes.
A filling may eventually become worn, fractured, stained, or compromised around its margins.
Your dentist may recommend replacement when there is evidence that the existing restoration is no longer adequately protecting or restoring the tooth.
However, an old filling does not automatically need to be replaced simply because it has been present for many years.
The condition of the restoration and surrounding tooth should be evaluated first.
How Should You Care for a Tooth With a Filling?
A restored tooth still requires normal oral hygiene.
Continue to:
- Brush twice daily
- Clean between your teeth every day
- Use fluoride toothpaste
- Maintain regular dental examinations
- Avoid biting extremely hard objects
- Address teeth grinding or clenching when appropriate
A filling restores part of the tooth, but it does not make the remaining natural tooth immune to future dental problems.
Can a Tooth With a Filling Get Another Cavity?
Yes.
A filling itself does not make the surrounding natural tooth permanently resistant to decay.
The remaining tooth structure can still be affected.
This is why brushing, interdental cleaning, fluoride exposure, and regular professional dental care remain important after restorative treatment.
What If the Tooth Needs More Than a Filling?
A filling is not appropriate for every damaged tooth.
If a tooth has extensive structural loss, a large fracture, or insufficient remaining tooth structure, your dentist may recommend another type of restoration.
Depending on the circumstances, this could involve a crown or another restorative treatment.
The decision depends on how much healthy structure remains and how the tooth needs to function.

Frequently Asked Questions
Does getting a filling hurt?
Local anesthesia can be used to numb the treatment area when necessary. You may feel pressure, vibration, or movement during treatment, but your dental team can provide additional anesthesia if you experience discomfort.
How long does a filling appointment take?
Treatment time varies depending on the size and location of the restoration and the number of teeth being treated. Smaller restorations can often be completed more quickly than large or complex ones.
How long will my tooth be sensitive after a filling?
Some temporary sensitivity can occur after treatment. The duration varies depending on the depth and condition of the tooth. Persistent or worsening symptoms should be evaluated by your dentist.
Why does my filling feel high when I bite?
The restoration may be making premature contact with the opposing tooth. Your dentist can check your bite and make a small adjustment if necessary.
Can composite fillings match my natural teeth?
Yes. Composite resin is available in tooth-colored shades and can be selected and shaped to blend with surrounding natural tooth structure.
Can I eat immediately after a filling?
Your dentist will provide specific instructions based on the type of restoration and anesthesia used. If your mouth is still numb, avoid chewing until normal sensation returns to reduce the risk of accidentally biting your cheek or tongue.
How do I know if an old filling needs replacement?
Your dentist can evaluate the filling for wear, fractures, compromised margins, recurrent decay, or other problems. An older filling does not automatically require replacement.
Can a large cavity still be treated with a filling?
It depends on how much healthy tooth structure remains. If the tooth has lost substantial structural integrity, a larger restoration such as a crown may provide more appropriate coverage.
A Filling Restores More Than a Visible Cavity
A dental filling involves a carefully controlled sequence of diagnosis, preparation, removal of affected tooth structure, adhesive treatment, composite placement, curing, shaping, and bite adjustment.
The objective is to restore the tooth while preserving as much healthy structure as possible.
For suitable cases, tooth-colored composite can provide a functional restoration while blending with the natural appearance of the smile.
At Pacha & Bijan Dental, treatment begins with evaluating the condition of the tooth and determining whether a filling is the appropriate restoration.
