At River Run Family Dentistry in New Braunfels, TX, we prioritize your oral health and offer effective solutions for common dental issues such as cavities and tooth decay. One of the most common procedures in dental care is the placement of dental fillings, which help restore the integrity of damaged teeth. This comprehensive guide will cover everything you need to know about dental fillings, including what they are, why they’re necessary, the different types available, and how to care for your fillings after treatment.

What Are Dental Fillings?
Dental fillings are materials used to repair teeth that have been damaged by decay, fractures, or wear. When a cavity forms, it creates a hole or weakened area in the tooth that must be treated to prevent further damage. Dental fillings restore the tooth’s structure and function, protecting it from future decay.
At River Run Family Dentistry, we use high-quality materials to ensure that your dental filling is both durable and aesthetically pleasing. The process involves removing the decayed portion of the tooth and filling the space with a restorative material, allowing the tooth to function normally again.
Why Are Dental Fillings Necessary?
Dental fillings are primarily used to treat cavities, but they can also be used to repair other types of tooth damage. Here are the main reasons why dental fillings are necessary:
- Treating Cavities: When a cavity forms due to tooth decay, a filling is necessary to restore the tooth’s health and prevent the decay from spreading to deeper layers of the tooth, which could lead to more serious issues such as infections or the need for root canal treatment.
- Repairing Cracked or Broken Teeth: Teeth that are chipped or cracked due to trauma or regular wear can be restored with a filling to prevent further damage and improve functionality.
- Worn Down Teeth: Over time, teeth can wear down from habits such as teeth grinding (bruxism) or frequent exposure to acidic foods and drinks. Fillings help restore the worn areas and protect the teeth from future harm.
- Cosmetic Reasons: Fillings can also be used to improve the appearance of a tooth, especially if it has been damaged or discolored.
Types of Dental Fillings
There are several types of dental filling materials available, each with its own set of benefits. At River Run Family Dentistry, we offer different options to meet the unique needs of our patients:
- Amalgam Fillings: Amalgam fillings, also known as silver fillings, are made from a mixture of metals, including silver, mercury, copper, and tin. These fillings are known for their strength and durability, making them ideal for filling larger cavities in the back teeth where chewing forces are the strongest.Pros:
- Long-lasting and durable
- Less expensive than other materials
- Can withstand heavy chewing forces
- Noticeable silver color
- Contains mercury, though in very small amounts considered safe for use
- Less aesthetically pleasing than tooth-colored options
- Composite Resin Fillings: Composite fillings are made from a mixture of plastic and fine glass particles. They are tooth-colored, which makes them ideal for restoring visible teeth or for patients who prefer a natural appearance.Pros:
- Matches the natural color of teeth
- Bonds well to the tooth structure
- Suitable for small to medium-sized fillings
- May not last as long as amalgam fillings
- Can wear down over time, especially on molars
- Requires more time to place than amalgam fillings
- Ceramic Fillings: Ceramic fillings are made from porcelain and are both durable and aesthetically pleasing. These fillings are tooth-colored and can be custom-made to match the exact shade of your natural teeth.Pros:
- Highly durable and resistant to staining
- Tooth-colored for a natural appearance
- Suitable for larger restorations
- More expensive than composite or amalgam fillings
- May require multiple visits for placement
- Glass Ionomer Fillings: Glass ionomer fillings are made from a combination of acrylic and a special type of glass. They are commonly used for fillings in areas that do not require heavy chewing forces, such as around the gum line or in children’s teeth.Pros:
- Releases fluoride, which can help protect the tooth from further decay
- Bonds well to the tooth structure
- Often used for temporary fillings or for primary teeth
- Less durable than other materials
- Not as aesthetically pleasing as composite fillings
The Dental Filling Procedure
The process of getting a dental filling is straightforward and typically takes just one visit. Here’s what to expect when you come to River Run Family Dentistry for a filling:
- Examination and Diagnosis: First, we’ll examine your tooth and take X-rays if necessary to assess the extent of the decay or damage. Once a cavity is diagnosed, we’ll discuss the best type of filling for your needs.
- Numbing the Area: To ensure a comfortable experience, the dentist will administer a local anesthetic to numb the area around the affected tooth. This prevents any pain during the procedure.
- Removing Decay: Once the area is numb, the dentist will carefully remove the decayed portion of the tooth using specialized dental instruments.
- Filling the Cavity: After the decay is removed, the dentist will clean the area and prepare it for the filling. The chosen filling material is then placed into the cavity and shaped to match the natural contours of the tooth.
- Curing the Filling: For composite resin fillings, a special light is used to harden (cure) the material. For other types of fillings, such as amalgam, the material will harden naturally over time.
- Final Adjustments: Once the filling is in place, the dentist will check your bite and make any necessary adjustments to ensure that the filling fits comfortably. The tooth is then polished for a smooth finish.
Aftercare for Dental Fillings
After your filling is placed, it’s important to care for it properly to ensure its longevity and prevent future cavities. Here are some tips for maintaining your dental fillings:
- Practice Good Oral Hygiene: Brush your teeth twice a day with fluoride toothpaste and floss daily to keep your teeth and fillings clean and free from plaque buildup.
- Avoid Hard or Sticky Foods: While dental fillings are durable, they can still be damaged by chewing on hard objects (such as ice or hard candy) or eating sticky foods that could dislodge the filling.
- Regular Dental Checkups: Visit River Run Family Dentistry for routine checkups and cleanings. During your visits, we will monitor the condition of your fillings and address any concerns.
- Address Grinding or Clenching: If you grind or clench your teeth, talk to your dentist about a mouthguard to protect your fillings and prevent wear on your teeth.
How Long Do Dental Fillings Last?
The longevity of a dental filling depends on several factors, including the type of material used, the size of the filling, and your oral hygiene habits. On average:
- Amalgam fillings can last 10 to 15 years or longer with proper care.
- Composite fillings typically last 5 to 7 years but may need to be replaced sooner in areas with heavy chewing.
- Ceramic fillings can last 15 years or more, depending on the location and care.
Regular dental visits will allow us to monitor the condition of your fillings and replace them if necessary.
When to Replace a Dental Filling
Over time, fillings can wear down, chip, or even fall out. If you notice any of the following signs, it may be time to replace your dental filling:
- Pain or Sensitivity: If you experience sensitivity to hot or cold foods or notice discomfort when biting down, it may indicate that your filling has worn down or become loose.
- Visible Damage: If you notice that a filling has chipped, cracked, or fallen out, it’s important to schedule a dental visit as soon as possible.
- Gaps or Rough Spots: If your filling feels rough or there is a noticeable gap between the filling and the tooth, it could be a sign that the filling needs to be replaced.
