A cavity may begin without pain, but untreated decay can continue weakening the tooth beneath the surface. Composite dental fillings in Las Vegas, NV, remove the damaged area and restore the tooth with material selected to blend naturally with your smile.
At Preferred Family Dentistry, Dr. Salmeh Jafarifar uses tooth-colored composite material to repair cavities, replace qualifying older fillings and rebuild certain chipped or worn areas. Each restoration is carefully shaped to support comfortable chewing while preserving as much healthy tooth structure as possible.
Call 702-433-0355 today to schedule an evaluation if you have tooth sensitivity, visible damage or concerns about a cavity or existing filling.
What Are Composite Dental Fillings?
Composite dental fillings are restorations made from a blend of resin and fine glass or ceramic particles. They are sometimes called white fillings, tooth-colored fillings or composite resin fillings because the material can be selected and shaped to resemble natural enamel.
Composite material bonds directly to the prepared tooth. Once placed and hardened, it restores the area where decay or damage has been removed and helps the tooth withstand normal biting and chewing pressure.
Composite dental fillings may be used to:
- Repair small to moderate cavities
- Restore chipped or worn tooth structure
- Replace certain older or damaged fillings
- Rebuild visible areas of front or back teeth
- Improve the appearance of dark or noticeable restorations
- Protect a tooth after damaged structure has been removed
The appropriate restoration depends on the size and location of the problem. A filling may work well when enough healthy tooth remains to support it, while a more extensively damaged tooth may require a crown.
Signs You May Need a Dental Filling
Cavities do not always cause symptoms in their early stages. Some are discovered during a routine dental exam or on diagnostic images before the tooth begins to hurt.
Possible signs of decay or filling damage include:
- Sensitivity to sweet, hot or cold foods
- Pain when biting or chewing
- A visible dark spot or small hole in a tooth
- Food repeatedly catching in one area
- A rough, sharp or chipped tooth surface
- Floss tearing around an existing filling
- A filling that feels loose or uneven
- Unexplained tooth discomfort
These symptoms can also be associated with cracks, gum recession, infection or other dental problems. Dr. Jafarifar will identify the cause before recommending treatment.
If you develop severe pain, facial swelling or a broken tooth, call 702-433-0355 promptly or visit our Emergency Dentistry page for additional guidance.
Why Cavities Should Be Treated Promptly
Tooth decay develops when acids produced by oral bacteria weaken the enamel. Once a cavity forms, the damaged portion of the tooth does not repair itself naturally.
Without treatment, decay may spread through the enamel into the softer dentin beneath it. A larger cavity can weaken the tooth, increase sensitivity and eventually reach the pulp containing the tooth’s nerves and blood vessels.
Prompt treatment may help:
- Remove decay before it spreads farther
- Preserve more healthy tooth structure
- Reduce the likelihood of a fracture
- Restore comfortable chewing
- Limit the need for more extensive treatment
- Protect the tooth from additional bacterial damage
A filling cannot reverse decay that has already reached the inner pulp or significantly weakened the tooth. In those cases, root canal treatment, a crown or another form of care may be required.
What Causes Cavities?
Cavities form through a combination of bacteria, plaque, diet and time. Plaque continually develops on the teeth and contains bacteria that feed on sugars and carbohydrates. The acids produced during this process can gradually weaken enamel.
Factors that may increase cavity risk include:
- Frequent sugary snacks or drinks
- Inconsistent brushing or flossing
- Plaque collecting between teeth
- Dry mouth
- Deep grooves in back teeth
- Exposed tooth roots
- Older or damaged dental restorations
- A personal history of frequent cavities
- Missing routine dental exams and cleanings
Preventive care, fluoride exposure and good home hygiene can lower your risk, but cavities may still occur. Regular monitoring helps our team identify changes before they become more extensive.
What to Expect During Your Filling Evaluation
Your appointment begins with a discussion of any pain, sensitivity or changes you have noticed. Dr. Jafarifar will examine the tooth and determine whether decay, a crack, filling damage or another issue is responsible.
Your evaluation may include:
- A detailed dental exam
- Checking the tooth for visible decay or damage
- Evaluating your response to temperature or pressure
- Examining existing fillings and nearby dental work
- Checking how your upper and lower teeth meet
- Using an intraoral camera to show visible concerns
- Taking digital X-rays when needed
Digital X-rays may reveal decay between teeth or beneath an older restoration where it cannot be seen during a visual examination. Dr. Jafarifar will review the findings and explain whether a filling is appropriate.
The Composite Filling Process
The exact process depends on the tooth and the amount of structure being restored, but composite filling treatment generally follows several steps.
Numbing the Treatment Area
Local anesthesia may be used to numb the tooth and surrounding tissue. Tell our team if you have experienced difficulty becoming numb or feel anxious about treatment so we can help make the appointment more comfortable.
Removing Decay or Damaged Material
Dr. Jafarifar removes the decayed portion of the tooth and any unstable material. The area is then cleaned and prepared for the composite restoration.
Applying the Composite Material
The tooth is kept dry so the bonding materials can adhere properly. Composite resin is applied in layers and hardened with a curing light.
Shaping and Polishing the Filling
Dr. Jafarifar shapes the restoration to recreate the natural contours of the tooth. Your bite is checked, and the filling is adjusted and polished so it feels smooth and comfortable.
A composite filling should restore the damaged area without creating a high spot or interfering with normal chewing. Contact us if your bite continues to feel uneven after the numbness has worn off.
Benefits of Composite Dental Fillings
Composite dental fillings offer both restorative and cosmetic advantages. Because the material bonds to the tooth and can be matched to surrounding enamel, it is useful in visible areas as well as many back teeth.
Potential benefits include:
- A natural-looking, tooth-colored appearance
- Shade selection based on surrounding enamel
- Direct bonding to the prepared tooth
- Preservation of healthy tooth structure when clinically appropriate
- Use on both front and back teeth
- Repair of certain chips and worn areas
- No visible silver-colored metal
- Shaping and polishing during the same treatment visit
No filling material is appropriate for every situation. The size of the cavity, tooth location, bite pressure and remaining tooth structure all influence which restoration is most suitable.
Composite Fillings for Front Teeth
Composite material is often selected for visible front teeth because it can be blended with nearby enamel and shaped directly during treatment.
It may be used to repair:
- Small cavities
- Minor chips
- Worn or uneven edges
- Small areas of surface damage
- Certain cosmetic irregularities
When material covers more of the visible surface to change the overall shape or appearance of a tooth, the treatment may be described as dental bonding or a bonded composite veneer.
Dr. Jafarifar will explain whether a filling, bonding treatment, veneer or another option best matches the condition of the tooth and your cosmetic goals.
Composite Fillings for Back Teeth
Composite fillings can also restore many cavities in molars and premolars. Back teeth experience greater chewing pressure, so the amount of damage and location of the cavity must be evaluated carefully.
A composite filling may be appropriate when:
- The cavity is small or moderate in size
- Enough strong tooth structure remains
- The filling can be kept dry during placement
- The restoration can withstand the forces of your bite
A large filling may not provide enough reinforcement when most of the tooth has been weakened. In that situation, a porcelain dental crown may offer more complete protection.
Composite Dental Fillings vs. Amalgam Fillings
Composite and amalgam are different restorative materials. Amalgam fillings have a silver-colored appearance and have historically been used in back teeth. Composite fillings are tooth-colored and bond to the prepared structure.
Reasons a patient may prefer composite include:
- A restoration that blends with the natural tooth
- No visible silver color
- Use in cosmetically noticeable areas
- The ability to bond material directly to the tooth
Existing amalgam fillings do not automatically need to be removed simply because of their color. Replacement may be considered when a filling is damaged, loose, leaking, associated with decay or otherwise no longer functioning properly.
Removing a stable restoration unnecessarily may sacrifice healthy tooth structure. Dr. Jafarifar will evaluate the filling and explain whether monitoring or replacement is appropriate.
Composite Filling vs. Dental Crown
A filling repairs a specific portion of a tooth. A crown surrounds the entire visible part above the gumline and provides more extensive coverage.
A filling may be appropriate when:
- The cavity affects a limited area
- The remaining tooth structure is strong
- The tooth does not have a major crack
- The restoration can withstand normal bite pressure
A crown may be recommended when:
- A large portion of the tooth is missing
- Several surfaces are weakened
- A fracture places the tooth at risk
- A very large filling has failed
- The tooth needs reinforcement after root canal therapy
Dr. Jafarifar has completed thousands of fillings and crowns during her career. She will recommend the most conservative restoration that can reasonably protect the tooth rather than automatically choosing the same treatment for every cavity.
Can Old Fillings Be Replaced With Composite?
An older filling may sometimes be replaced with composite material, but the decision depends on the condition of the tooth after the existing restoration is removed.
Replacement may be considered when an old filling:
- Is cracked or broken
- Has become loose
- No longer seals the tooth properly
- Has decay developing around or beneath it
- Creates discomfort when biting
- Needs replacement for another clinical reason
If removal reveals extensive damage or limited remaining support, a crown may be more appropriate than another filling. Dr. Jafarifar will review the options after evaluating the tooth and available imaging.
Do Composite Fillings Hurt?
Local anesthesia is commonly used to keep the treatment area comfortable while decay is removed and the restoration is placed. You may notice pressure, vibration or movement, but the tooth should remain numb during treatment.
Temporary sensitivity may occur afterward, especially if the cavity was deep or located near the gumline. The tooth may also feel slightly different until the surrounding tissues settle and you become accustomed to the new restoration.
Contact our office if you experience:
- Severe or increasing pain
- Swelling
- A filling that feels too high
- Sharp pain when biting
- Sensitivity that does not improve
- A loose, cracked or missing filling
A minor bite adjustment may resolve discomfort when the filling contacts the opposing tooth too early.
How Long Do Composite Fillings Last?
Composite fillings can function for years, but no dental restoration is permanent. Their lifespan depends on the size and location of the filling, your bite, oral hygiene, diet and habits such as grinding or chewing ice.
Factors that may shorten the life of a filling include:
- Heavy grinding or clenching
- A very large restoration
- Frequent chewing on hard objects
- New decay around the filling
- Poor oral hygiene
- Changes in the tooth or bite
Routine exams allow Dr. Jafarifar to check the filling’s edges, surface and stability. Early attention to wear or leakage may help prevent a larger problem from developing beneath the restoration.
Do Composite Fillings Stain?
Composite material can gradually absorb stains, particularly when located on visible teeth and frequently exposed to coffee, tea, tobacco, red wine or other pigmented substances.
Professional cleaning and polishing may improve some surface discoloration, but composite material does not respond to whitening gel in the same way as natural enamel.
If you are considering Zoom teeth whitening or take-home whitening, discuss your goals before a visible filling is placed. The composite shade can then be selected with your broader cosmetic plan in mind.
How to Care for Composite Fillings
Composite fillings do not require a separate daily routine, but the natural tooth around them still needs protection from plaque and decay.
To care for your restoration:
- Brush at least twice daily
- Floss or clean between your teeth every day
- Keep routine dental exams and teeth cleanings
- Limit frequent sugary foods and beverages
- Avoid biting ice, pens or other hard objects
- Wear a night guard if recommended for grinding
- Contact our office if the filling feels rough, loose or painful
Decay can form around a filling if plaque accumulates near its edges. Consistent home care remains essential after the tooth has been restored.
What Should You Do if a Filling Falls Out?
Call 702-433-0355 promptly if a filling becomes loose or falls out. The exposed tooth may be sensitive and more vulnerable to additional damage.
Until your appointment:
- Avoid chewing on the affected side
- Keep the tooth gently clean
- Avoid very hot, cold or sugary foods if the area is sensitive
- Do not place household glue or adhesive in the tooth
- Contact us immediately if you develop swelling or severe pain
Dr. Jafarifar will examine the tooth to determine why the filling failed and whether it can be replaced with composite or needs a different restoration.
How Much Do Composite Dental Fillings Cost?
The cost of treatment depends on the size and location of the cavity, the number of surfaces involved and the condition of the tooth.
Factors may include:
- The number of teeth being treated
- The extent of decay or damage
- The location of the filling
- Whether an older restoration must be removed
- Whether digital X-rays are needed
- Whether the tooth requires a filling or more extensive restoration
After your examination, our team will explain the recommended treatment and associated cost. Dental insurance coverage varies according to your individual plan and benefits.

FAQ About Composite Dental Fillings
What are composite fillings made from?
Composite dental fillings are made from a tooth-colored resin combined with fine glass or ceramic particles. The material is applied in layers, hardened and shaped to restore the tooth.
Are composite dental fillings suitable for front teeth?
Yes. Composite material is frequently used on front teeth because its shade and contours can be matched to the surrounding enamel.
Can composite dental fillings be used on molars?
They can restore many small to moderate cavities in back teeth. A crown may be recommended when extensive damage or heavy bite pressure makes a filling less predictable.
How long do composite fillings last?
The lifespan varies according to the filling’s size, location, bite pressure, oral hygiene and daily habits. Dr. Jafarifar will check your restorations during routine exams.
Does getting a composite filling hurt?
Local anesthesia is commonly used to numb the tooth. Temporary sensitivity may occur after treatment, but severe or continuing pain should be evaluated.
Can an old metal filling be replaced with composite?
Sometimes. Dr. Jafarifar will evaluate the existing filling and remaining tooth structure. A larger restoration may require a crown instead of another filling.
Can a cavity form around a composite filling?
Yes. New decay may develop around the edges if plaque accumulates or the seal weakens. Daily oral hygiene and routine dental exams remain important.
Can composite fillings be whitened?
No. Whitening gel lightens natural enamel but does not change the shade of composite material. Discuss whitening plans before replacing a visible filling.
Do composite fillings require special care?
No special products are generally required. Brush, floss, maintain routine dental visits and avoid chewing hard objects that could damage the filling.
