River Point Dental provides dental fillings in Jacksonville, Florida, for patients who need to repair cavities, strengthen worn teeth or restore small chipped areas. This page explains what dental fillings are, how the procedure works, what materials may be available and what to expect before and after treatment so you can make confident decisions about your care.
Dental Fillings Explained
A dental filling is a restorative treatment used to replace tooth structure lost to decay, minor fractures or everyday wear. After the damaged portion of the tooth is removed, a filling material is placed to seal the area, restore the tooth’s shape and protect the inner layers from further damage. Fillings are commonly used for small to medium cavities and minor repairs that do not require a more extensive restoration.
Patients often search for what is a dental filling, how does a dental filling work and types of dental fillings. In general, fillings stop cavity progression, rebuild the biting surface and help protect the tooth from additional breakdown. Tooth-colored composite resin is a popular option because it bonds to the tooth and blends with your smile. Amalgam, also called a silver filling, may be used in some cases because of its strength and durability. Glass ionomer may be recommended in select situations, such as areas near the gumline or for temporary stabilization.
Our dentist will evaluate the size, location and condition of the tooth before recommending the best filling material for your needs. The goal is to preserve as much natural tooth structure as possible while restoring comfort, function and long-term protection.
Benefits of Dental Fillings
- Stops cavity progression and helps protect the inner tooth.
- Preserves natural tooth structure compared to more extensive restorations.
- Restores comfortable chewing and reduces sensitivity.
- Provides a smooth surface that is easier to clean.
- Offers tooth-colored options that blend with your natural smile.
- Can be completed in a single visit for most small to medium cavities.
How Dental Fillings Work
The dental filling procedure follows a precise sequence designed for comfort, accuracy and long-term function:
- Exam and imaging: Our dentist confirms the size and location of decay with an exam and X-rays.
- Comfort measures: Local anesthetic numbs the area so you remain comfortable during treatment.
- Decay removal: Damaged tooth structure is carefully removed while preserving healthy enamel and dentin whenever possible.
- Tooth preparation: The surface is shaped and cleaned; deep areas may receive a protective liner to help shield the inner tooth.
- Material placement: The filling material is placed, shaped and hardened to restore the missing portion of the tooth.
- Bite adjustment and polish: The filling is adjusted to fit your bite and polished for a smooth, comfortable finish.
Most dental filling visits take 30 to 60 minutes per tooth, depending on the size and location of the cavity. Many patients ask, does a dental filling hurt? With local anesthetic, you should feel pressure and vibration but not pain. Mild post-visit tenderness is common and usually fades within a few days.
Choosing Filling Materials And Longevity
Composite vs. amalgam fillings is a common comparison. Composite fillings offer natural color, bond directly to the tooth and are often preferred for visible areas or patients who want a more seamless appearance. Amalgam fillings are known for durability and may be recommended in areas that handle heavier chewing forces. Glass ionomer may be used in specific cases where fluoride release or temporary support is beneficial.
How long do dental fillings last? Composite fillings can last five to 10 years or more with good care. Amalgam fillings often last 10 to 15 years or longer. The lifespan of any filling depends on the cavity size, filling location, bite forces, oral hygiene, diet and regular dental checkups. Clenching, grinding, frequent snacking or poor brushing and flossing habits can shorten the life of a filling.
What To Expect Before And After Treatment
Before your visit, eat a light meal and share your medical history, medications and any concerns with our team. During treatment, local anesthetic keeps the area numb and comfortable. If you feel pressure, sensitivity or need a break, raise a hand so adjustments can be made.
After treatment, wait until numbness fully wears off before chewing to avoid biting your cheek or tongue. Tooth-colored fillings can be chewed on once you have feeling back, but it is wise to avoid very hard or sticky foods at first. If an amalgam filling is placed, our team may recommend chewing on the opposite side for the rest of the day while the material fully sets. Temporary sensitivity to cold, heat or pressure is common and should improve within two weeks.
- Manage mild soreness with over-the-counter pain relievers as advised.
- Brush with fluoride toothpaste and floss daily to protect the filling margins.
- Avoid very hard or sticky foods on new fillings for the first day.
- Call the office if your bite feels high, pain wakes you at night or sensitivity lasts longer than two weeks.
Regular exams help detect early wear, leakage or cracks around existing fillings so small issues can be addressed before they require larger treatment.
Frequently Asked Questions
How Long Do Dental Fillings Last?
Composite fillings often last five to 10 years or more, while amalgam fillings may last 10 to 15 years or longer. Lifespan varies based on the size and location of the filling, your bite, oral hygiene habits, diet and whether you clench or grind your teeth.
Will I Feel Pain During A Filling?
Local anesthetic is used to prevent pain during a dental filling. You may feel pressure, vibration or movement while our dentist removes decay and places the filling, but the tooth should remain numb. Mild soreness or sensitivity afterward is common and usually improves within a few days.
Can A Cavity Be Too Large For A Filling?
Yes. A filling is best for small to medium areas of damage. If a cavity is very large, the tooth is cracked or too much structure has been weakened, another treatment may be recommended to provide stronger protection. If decay reaches the nerve, root canal therapy may be needed before the tooth is restored.
What Are Tooth-Colored Fillings Made Of?
Tooth-colored fillings are made of composite resin, a durable blend of resin and fine glass particles. The material is matched to your natural tooth shade, placed in layers and hardened with a curing light. Composite bonds directly to the tooth and can restore both appearance and function.
Are Silver Amalgam Fillings Safe?
Dental amalgam has been used for decades and is considered safe for most patients. Some people choose tooth-colored composite fillings for cosmetic reasons or because bonding is preferred for the location of the cavity. Our dentist can review your options and recommend the material that best fits your needs.
What If A Filling Chips Or Falls Out?
Avoid chewing on that side, keep the area clean and contact the dental office promptly. A chipped, loose or missing filling can leave the tooth vulnerable to sensitivity, decay or further fracture. Timely repair helps protect the tooth and may prevent the need for more extensive treatment.
How Do I Know If I Need A Filling?
Common signs include lingering sensitivity to sweets or cold, pain when biting, rough edges you can feel with your tongue or floss catching between teeth. Some cavities do not cause symptoms at first, which is why routine dental exams and X-rays are important for early detection.
