What Is a Dental Filling?
A dental filling is a restoration used to repair a tooth affected by decay or minor damage. The decayed portion of the tooth is removed, and the area is restored to help protect the tooth’s shape, strength, and function.
Treating a cavity early can help prevent decay from spreading and may reduce the risk of needing more extensive dental treatment later.
The type of filling material used depends on factors such as the location of the tooth, the amount of tooth structure being restored, and your individual needs. If you have a metal allergy or preferences about your filling material, let our team know so we can discuss appropriate options.
How Do I Know If I Need a Filling?
You may need a dental filling if a tooth has decay, minor damage, or an existing filling that is worn or damaged. However, some cavities cause no noticeable symptoms and are only discovered during a routine dental exam or X-ray.
Possible signs that a tooth may need treatment include:
- Tooth sensitivity
- Pain or discomfort when biting or chewing
- A visible dark spot or area of decay
- A chipped or damaged tooth
- An old filling that is worn or damaged
If you are experiencing tooth pain or sensitivity, a dental exam can help determine whether a filling or another treatment is appropriate.
What Happens During a Dental Filling?
Most small cavities can be treated in a single appointment. We begin by examining the tooth and taking X-rays when needed to determine the location and extent of the decay.
Dr. Norman Lewis will explain the findings and recommend a treatment option designed to remove damaged tooth structure while preserving as much healthy tooth as possible.
A typical dental filling appointment may include:
- Numbing the treatment area with local anesthesia
- Offering nitrous oxide when appropriate for additional comfort
- Removing the decayed portion of the tooth
- Cleaning and preparing the area
- Placing the filling material
- Checking the shape and bite of the restoration
We explain the treatment as we go, and you can ask for a break whenever you need one.
Does Getting a Dental Filling Hurt?
Dental fillings are typically performed after the treatment area has been numbed with local anesthesia to help keep you comfortable. Nitrous oxide may also be available when appropriate.
After treatment, the tooth may feel mildly sensitive or tender for a few days. This often improves as the tooth adjusts.
If discomfort is severe or persistent, or if your bite does not feel right after the filling, contact our office so we can evaluate the tooth.
How Long Do Dental Fillings Last?
How long a dental filling lasts depends on the filling material, the location and size of the restoration, your bite, your oral hygiene, and habits such as clenching or grinding.
Good daily care and regular dental visits can help protect both your filling and the surrounding tooth. We recommend:
- Brushing twice a day with fluoride toothpaste
- Cleaning between your teeth daily
- Keeping regular dental checkups
- Avoiding habits that may damage teeth or restorations
If you grind or clench your teeth, we can also discuss whether a night guard may help protect your fillings and natural teeth.
Caring for Your Tooth After a Filling
Mild temporary sensitivity after a filling is common. Depending on the restorative material used, we may also recommend avoiding sticky or very hard foods for a period after treatment.
Before you leave, our team will provide instructions based on your specific restoration and answer any questions you have about eating, brushing, flossing, or sensitivity.
When Is a Filling Not Enough?
A dental filling may not be enough when decay is extensive, the nerve of the tooth is involved, or a fracture has weakened a significant portion of the tooth.
In these situations, another type of treatment, such as a crown, may be considered.
Symptoms such as persistent sharp pain, swelling, or significant tooth damage should be evaluated promptly. Dr. Norman Lewis will explain the condition of the tooth, the available treatment options, and what to expect during treatment and recovery.
