When a tooth has been damaged by decay or wear, a filling does more than simply plug a gap — it restores the tooth’s shape, support, and ability to function without pain. A carefully placed restoration preserves as much healthy tooth as possible while protecting the underlying structure from further breakdown. For patients, that means fewer emergencies, improved chewing comfort, and a lower chance of needing more extensive care later on.
Tooth decay continues to affect people of all ages, making restorative treatments a routine and essential part of contemporary dental care. Advances in dental materials and adhesive techniques now allow clinicians to rebuild teeth in ways that are conservative, long-lasting, and visually discreet. Our focus is on returning teeth to reliable function while keeping your smile looking natural.
Attempts to repair teeth go back millennia, but the last century has seen the most dramatic shifts in restorative materials and methods. Early fillings relied on metals that emphasized durability; modern dentistry balances strength with biocompatibility and appearance. Understanding how materials evolved helps explain why clinicians now prefer mercury-free, tooth-colored options for many situations.
Every restoration starts with an individualized treatment plan. We assess the extent of decay, the remaining tooth structure, and your long-term oral health goals before recommending a material and technique. The result is a restoration designed to last while blending seamlessly with the natural tooth.
There is no single “best” filling for every situation. The ideal choice depends on the size and location of the cavity, the forces a tooth must withstand, and the patient’s cosmetic priorities. Some materials excel where durability is essential, while others prioritize blending invisibly with the surrounding tooth.
Material science in dentistry now offers a menu of options that were not available to previous generations. Many contemporary restorations bond to tooth structure, which can strengthen the remaining enamel and dentin and allow for more conservative preparations. This bonding capability is a major reason tooth-colored restorations have become so popular.
Composite resins are resin-based materials mixed with tiny glass or ceramic particles. They are available in a wide range of shades so a skilled clinician can match the surrounding tooth. Composites are bonded directly to the tooth and can often be placed with minimal removal of healthy structure, making them a conservative choice for many cavities and cosmetic repairs.
Because they rely on a bonding process rather than bulk strength alone, composites are great for visible areas that require a natural appearance. Like any restoration, they require proper maintenance and may need replacement over time depending on wear and oral habits.
Amalgam has a long record of clinical success, especially in areas where chewing forces are high. These restorations are durable and can be appropriate where strength is the overriding concern. They are less commonly chosen today for visible teeth because they do not match natural tooth color.
Glass ionomer cements bond to tooth structure and slowly release fluoride, which can help protect vulnerable areas from recurrent decay. They are often used in pediatric dentistry, near the gumline, or as a temporary or transitional restoration. While they are more aesthetic than metal, they are not as wear-resistant as other options.
Ceramic restorations are crafted outside the mouth and then bonded into place. They are highly resistant to staining and wear, and they provide a very natural appearance. Because these are fabricated restorations, they are an excellent choice when a larger portion of the tooth must be rebuilt without resorting to a full crown.
Gold is prized for its longevity and compatibility with surrounding tissues. Though less commonly used today due to cosmetic preferences and cost, gold remains an excellent material for durable restorations in back teeth when longevity is the top priority.
Our goal is to make cavity treatment predictable and comfortable. After a thorough examination and any necessary X-rays, we discuss the recommended treatment and answer your questions before starting. Most routine fillings can be completed in a single visit and typically take around an hour, depending on the tooth and the material chosen.
Local anesthesia is used when appropriate so that the treated tooth is numb during preparation. Decay is removed carefully using rotary instruments, lasers, or air-abrasion devices to preserve as much healthy tooth as possible. When the area is clean and shaped, the chosen restorative material is placed and finished to restore function and appearance.
Finishing steps include checking the bite, polishing the restoration, and making any small adjustments to ensure ease of chewing and comfort. We take extra care with patient comfort and explain each step so you feel informed and at ease throughout the process.
For patients who experience anxiety, we offer options to reduce stress during treatment. Discussing comfort strategies before your visit helps us tailor the experience to your needs so the appointment is efficient and low-stress.
Most patients go back to normal activities immediately after a filling, but there are a few practical things to keep in mind during the first day or two. A new restoration may feel slightly different in the mouth while you adjust, and temporary sensitivity to temperature or pressure is common as the tooth settles.
Until the anesthetic wears off
Take care not to chew on the treated side or bite the cheeks or tongue while numbness persists. Normal sensation typically returns within an hour or two, but protecting soft tissues prevents accidental bites and discomfort.
Short-term sensitivity is normal
Sensitivity to hot, cold, or pressure often resolves within a few days to a couple of weeks. If sensitivity intensifies or does not improve, contact us so we can evaluate whether an adjustment or additional treatment is needed.
Long-term maintenance
Good oral hygiene, routine dental examinations, and timely professional cleanings extend the life of any restoration. Heavy grinding, chewing hard objects, or poor home care can shorten a filling’s lifespan — we can recommend protective measures such as night guards when indicated.
Fillings are effective solutions, but they are not necessarily permanent. Over years of use, restorations can wear, chip, or develop marginal leakage where decay can recur. Regular dental checkups allow your dentist to inspect restorations visually and radiographically and to catch small problems before they require more extensive treatment.
When a filling shows signs of failure — such as persistent sensitivity, a visible fracture, or recurrent decay at the edges — there are conservative options that preserve as much tooth structure as possible. In many cases an updated restoration or an inlay/onlay can extend function without moving directly to a crown.
Thoughtful maintenance also includes lifestyle adjustments. Reducing frequent exposure to sugary foods and practicing consistent brushing and flossing reduce the chance of future cavities. For patients with habits like clenching or chewing ice, targeted interventions can protect both natural teeth and restorations.
Our team at Today's Dentistry San Jose is available to review your restorations during routine visits and to recommend simple, practical steps to help them last. Early detection and conservative care are the best strategies for preserving your natural teeth and restorations for the long term.
Overall, modern dental fillings are designed to be conservative, durable, and unobtrusive. If you have questions about which material is right for your situation or what to expect during treatment, please contact us for more information.
If the pleasure of eating a delicious bowl of ice cream or sipping a soothing cup of tea gets overshadowed by dental pain that makes you wince; it's time to contact our office. As skilled providers of care, we'll determine what's causing your discomfort and perform the treatment required to alleviate your symptoms and get you back on the road to oral health.
Cavities develop because of an infectious process that causes progressive damage to tooth structure. Despite starting as a pinpoint defect on the outermost enamel layer of your tooth, untreated dental decay progressively compromises more and more healthy tooth structure as it works its way to the inner layers of your tooth.
Yes, you can still develop tooth decay on other surfaces of the tooth, around the margins of an old filling, or in fewer instances, recurrent decay underneath it. For this reason, it's essential to maintain excellent oral hygiene, a diet low in sugary beverages and sweets, and be sure to visit our office for routine checkups and care. While tooth decay is second only to the common cold in frequency, it's almost entirely preventable.
We value the time and comfort of our patients. If cavities are located on adjacent teeth, or in the same section of your smile, it may be possible to treat more than one tooth during your visit. However, how much is done each visit depends on several factors. We keep our patients well informed and tailor every treatment plan and visit to address their unique needs.
Addressing concerns on the presence of elemental mercury in silver fillings, the American Dental Association (ADA), The Center for Disease Control and Prevention (CDC), the FDA, and the World Health Organization have all stated that amalgam restorations do not pose a risk to health. However, individuals with allergies or sensitivities to the metals in dental amalgam are advised to pursue other restorative options.
Dental fillings are performed under local anesthesia to help ensure your comfort throughout the entire procedure. The involved tooth remains completely numb for the extent of your visit. Within one or two hours after the procedure is completed, the local anesthetic will gradually wear off, and normal sensations return.
A tooth-colored composite filling is fully hardened and set by the end of your visit. However, we may advise you to wait a couple of hours until the local anesthesia has completely worn off. This advice is to help ensure you don't accidentally bite your lip, cheek, or tongue while still numb.
The lifetime of a dental filling varies depending on the type of material used. While popular dental materials can last a decade or more with proper care, they can degrade over time, wear down, or even break. When this happens, you may experience some tooth sensitivity, a jagged edge, or a loose or dislodged piece of filling material. Whatever the case may be, it's essential to get the filling replaced before the tooth sustains further damage or other consequences arise. Beyond taking good care of your smile to help ensure the longevity of your fillings, our office regularly checks the status of your existing fillings as part of a routine checkup exam.
Dental fillings are an essential investment that serves to preserve and protect the health of your smile. With that said, how much a filling costs depends on the number of surfaces of the tooth involved and the filling material that is used. Amalgam restorations are the most economical. While tooth-colored composite fillings have a slightly higher cost, they offer the added benefits of being metal-free and much more aesthetically pleasing. Ceramic fillings, inlays, and onlays are more expensive than the preceding options but provide outstanding, long-lasting, and natural-looking results.
Dental insurances typically cover the cost of dental fillings. While we work with you to maximize your insurance benefits, there may still be an out-of-pocket expense. At the office of Today's Dentistry San Jose, we strive to help you begin care without any additional financial stress or delay.
Dental fillings are restorative materials used to repair teeth that have been damaged by decay or wear and to restore normal form and function. A filling removes diseased tissue and replaces it with a material that seals the tooth, prevents further breakdown, and helps the tooth withstand chewing forces. By addressing decay early, fillings reduce the likelihood of more extensive treatments such as root canals or extractions.
Modern fillings do more than simply plug a hole; they often bond to the remaining tooth structure to reinforce weakened enamel and dentin. This conservative approach preserves healthy tissue while restoring comfort and chewing efficiency. Properly placed restorations also help maintain the natural contours of the tooth and the overall balance of the bite.
Several materials are available for fillings, each with different strengths and aesthetic qualities. Composite resins are tooth-colored, bond to the tooth, and are often chosen for visible areas where appearance matters, while glass ionomer releases fluoride and can be useful near the gumline or for pediatric patients. Ceramics and laboratory-made inlays/onlays offer superior wear resistance and appearance for larger restorations, and metals like gold remain an option when longevity and durability are the priority.
The choice of material depends on the size and location of the defect, the forces the tooth will endure, and the patient’s priorities for appearance and longevity. Bonding techniques used with modern materials allow for more conservative tooth preparation and improved retention. Your clinician will explain the benefits and trade-offs of each option so you can make an informed decision about your restoration.
Contemporary restorative materials are extensively tested for safety and clinical performance, and clinicians select options with established records of biocompatibility. Tooth-colored composites and ceramics are mercury‑free and designed to be stable in the oral environment, minimizing adverse tissue reactions. Glass ionomer cements and well-placed metallic restorations also have long histories of reliable use when chosen for appropriate indications.
When evaluating materials, dentists consider factors such as allergy history, the location of the restoration, and overall oral health to ensure a compatible choice. If you have specific health concerns or sensitivities, discuss them with your provider so they can recommend materials that best match your needs. Thorough diagnosis and controlled placement techniques further reduce potential risks and improve outcomes.
A filling appointment usually begins with a dental exam and any necessary X-rays to determine the extent of decay and the tooth's condition. Local anesthesia is used when appropriate so that the tooth is numb during preparation, and the dentist removes the decayed portion using rotary instruments, lasers, or air abrasion while preserving as much healthy structure as possible. After shaping the cavity, the chosen material is placed, bonded or adapted to the tooth, and finished to restore proper form and occlusion.
Finishing steps include checking the bite, polishing the restoration, and making small adjustments to ensure comfort and function. Many routine fillings are completed in a single visit, though more complex cases or lab-fabricated restorations like inlays/onlays may require additional appointments. Throughout the visit, clinicians explain each step and address any concerns to keep the experience predictable and comfortable.
The lifespan of a filling depends on the material used, the size and location of the restoration, and the patient's oral habits and hygiene. Composite and glass ionomer restorations may last many years with proper care, while ceramic and gold restorations often provide even longer service in high-wear areas. Factors such as bruxism, chewing hard objects, frequent exposure to sugars, and poor oral hygiene can all shorten the useful life of a restoration.
Regular dental checkups allow your clinician to monitor restorations for wear, marginal breakdown, and recurrent decay so minor issues can be addressed early. When problems are detected, conservative options such as repair or replacement with an updated restoration can preserve tooth structure. Our team at Today's Dentistry San Jose emphasizes preventive care and individualized maintenance plans to help restorations last as long as possible.
It is common to experience some mild sensitivity to hot, cold, or pressure for a few days to a couple of weeks after a filling as the tooth settles and nerves adjust. Until numbness from local anesthesia wears off, avoid chewing on the treated side to prevent biting soft tissues or causing damage. If sensitivity gradually improves, it is usually part of normal healing; persistent or worsening pain should be evaluated by your dentist.
If your bite feels uneven or you experience sharp pain when biting, contact your dental team for an adjustment because high spots can often be corrected with a simple reshaping. Maintaining good oral hygiene and avoiding very hard foods during the initial healing period will help protect the new restoration. If signs of infection, swelling, or continuous sharp pain occur, prompt evaluation is important to determine if additional treatment is needed.
Minor issues such as small chips or localized staining can sometimes be repaired with conservative techniques that preserve the original restoration and surrounding tooth structure. Replacement is considered when a filling shows significant wear, marginal breakdown, recurrent decay, or structural compromise that jeopardizes the tooth's long-term health. Your dentist will weigh the condition of the filling, the amount of remaining tooth, and long-term prognosis when recommending repair versus replacement.
Modern adhesive and restorative techniques often allow for partial repairs or upgrades, such as replacing an older composite with a more durable ceramic inlay when appropriate. Regular examinations and radiographs help detect early signs of failure so interventions can be as conservative as possible. Discussing the options and expected outcomes with your clinician helps ensure a plan that balances preservation and lasting function.
Advances in composite resin technology and bonding systems have significantly improved the strength and durability of tooth-colored restorations, making them suitable for many back teeth when placed correctly. While amalgam has a long history of strength under heavy chewing forces, modern composites can perform comparably in many clinical situations and offer the advantage of conserving more natural tooth structure. The longevity of either material depends on proper case selection, preparation design, and the patient's oral environment.
For larger defects or teeth subject to extreme forces, clinicians may recommend alternatives such as ceramic inlays/onlays or crowns that provide additional structural support. Bite adjustments, occlusal guards for bruxism, and periodic monitoring further enhance the performance of any restoration. Your dentist will recommend the material that best meets your functional needs and aesthetic goals.
Preventing cavities relies on consistent daily habits and regular professional care, including twice-daily brushing with fluoride toothpaste and daily flossing to remove plaque from between teeth. Limiting frequent consumption of sugary and acidic foods and drinks reduces the environment that supports decay, and using fluoride treatments or sealants when indicated can provide extra protection for vulnerable surfaces. Routine dental exams and professional cleanings help detect early lesions and allow for minimally invasive interventions before larger restorations are needed.
For patients with specific risk factors such as dry mouth, orthodontic appliances, or a history of recurrent decay, your dental team can create a customized prevention plan that may include prescription-strength fluoride, dietary counseling, or targeted topical therapies. Addressing habits like nail biting or chewing ice and managing conditions that contribute to enamel erosion also help preserve natural tooth structure. Consistent communication with your dental provider ensures prevention strategies remain effective as your needs change.
A filling is appropriate when decay or damage is limited and sufficient healthy tooth structure remains to support a direct restoration. When a large portion of the tooth is compromised or when the remaining walls are thin, an indirect restoration such as an inlay, onlay, or crown may be recommended to restore strength and protect the tooth from fracture. These laboratory-fabricated options distribute chewing forces more effectively and can extend the functional life of the tooth when extensive rebuilding is required.
Your dentist evaluates each tooth for structural integrity, the extent of decay, and occlusal demands before recommending the most conservative and durable solution. In many cases, inlays and onlays allow preservation of more natural tooth structure than a full crown while providing superior longevity compared with a direct filling. If you are uncertain about the recommendation, ask your clinician to explain the reasons for the chosen approach and the expected benefits for long-term oral health.
