Dental Fillings

Repair cavities and restore strength to damaged teeth with durable, tooth-colored fillings.

Dental fillings are used to repair teeth affected by cavities, cracks, or minor damage. At Austin Longevity , we use modern, tooth-colored composite materials that bond directly to the tooth structure and restore both function and appearance. Fillings stop decay from progressing, prevent further damage, and protect the inside of the tooth from infection. Modern composite fillings have largely replaced traditional silver amalgam fillings for most cases. Composite fillings are made of a tooth-colored resin that's matched to your natural tooth shade, making them virtually invisible. They also bond directly to the tooth, which means less of your natural tooth structure needs to be removed compared to amalgam fillings. The result is a stronger, more aesthetic restoration that preserves more of your tooth. The filling procedure is straightforward and typically completed in one visit lasting 30 to 60 minutes per tooth. After numbing the area with local anesthesia, the dentist removes any decayed or damaged tooth material, cleans the area, and applies the composite resin in layers, hardening each layer with a special light. The filling is then shaped and polished to match the natural contours of your tooth and feel comfortable in your bite. Most patients return to normal eating shortly after the appointment, once the numbness from the anesthesia has worn off.

Catching cavities early is one of the most important things we do at Austin Longevity . Small cavities are simple to treat with a small filling, while delaying treatment can lead to larger restorations, root canals, or even tooth loss. Regular checkups and X-rays help us identify decay at the earliest possible stage. We use composite materials matched precisely to your tooth color so fillings blend seamlessly with your natural teeth, even on front teeth where appearance matters most. Our technique focuses on preserving as much healthy tooth structure as possible while fully removing decay. We also discuss the underlying causes of cavities (diet, hygiene, dry mouth, etc.) so we can help you prevent future decay rather than just treating it as it appears.

How it works

A clear path from consultation to confident result.

Every patient’s journey looks a little different, but the road map is the same: thoughtful planning, careful preparation, precise treatment, and lasting protection.

Detect

Visual exam, X-rays, and sometimes specialized cavity-detection technology identify decay or damage in the tooth, often before symptoms appear.

Remove

Under local anesthesia, the decayed or damaged portion of the tooth is gently removed using small dental instruments.

Fill

Tooth-colored composite resin is applied in layers and hardened with a curing light, then shaped and polished to match your natural tooth.

Protect

Good brushing, flossing, and routine cleanings help prevent future decay and protect your filled tooth long-term.

Frequently asked

Questions we hear most often.

Still wondering whether this is the right path for you? Schedule a consultation and we’ll talk through your specific goals.

How long do dental fillings last?
Composite fillings typically last 7 to 10 years, while amalgam fillings can last 10 to 15 years or longer. Longevity depends on the size and location of the filling, your oral hygiene, your bite, and habits like grinding. Smaller fillings on front teeth often last longer than large fillings on back teeth that experience heavy chewing forces.
How much does a dental filling cost?
Composite fillings typically cost between $150 and $400 per tooth, depending on the size and number of surfaces affected. Most insurance plans cover fillings at 70% to 100% after the deductible. Larger fillings or fillings on multiple surfaces of the same tooth cost more than small single-surface fillings.
Are tooth-colored fillings as durable as silver fillings?
Modern composite fillings are very durable and suitable for most situations, including molars that experience significant chewing forces. While amalgam fillings have historically been considered more durable, modern composites have closed much of that gap and offer significant aesthetic advantages. For very large fillings on back teeth, a crown may be a better long-term option than a filling of either material.
Does getting a filling hurt?
The procedure is typically comfortable. Local anesthesia numbs the tooth and surrounding area completely before the dentist begins, so you won't feel pain during the filling. Some patients experience mild sensitivity for a few days after the filling, particularly to cold, which usually resolves on its own as the tooth adjusts.
Can fillings fall out?
Yes, fillings can occasionally come loose or fall out, particularly older fillings or those subjected to grinding or biting on hard objects. Decay can also develop around the edges of an old filling, causing it to fail. If a filling falls out, contact us right away. The exposed tooth is more vulnerable to damage and decay until it's restored.
How soon can I eat after getting a filling?
You can typically eat shortly after a composite filling because the material hardens immediately under the curing light. The main reason to wait is the local anesthesia, which can make it easy to bite your cheek or tongue while still numb. Most patients eat normally within an hour or two, once the numbness has worn off.
Are amalgam (silver) fillings safe?
Amalgam fillings have been used safely for over 150 years and continue to be considered safe by major health organizations including the FDA, ADA, and WHO. While amalgam contains mercury, it's bound within the metal alloy and not released in harmful amounts. However, many patients now prefer composite fillings for aesthetic reasons, and we offer both options based on your preferences.
Do I need a filling if my tooth doesn't hurt?
Yes. Many cavities don't cause pain until they're large or have reached the nerve. Waiting for a cavity to hurt before treating it often means the decay has progressed significantly, possibly to the point of requiring a root canal or crown instead of a simple filling. Regular dental exams and X-rays catch cavities at the earliest, easiest-to-treat stage.
Will my filling be noticeable?
Composite fillings are tooth-colored and matched to your natural tooth shade, making them virtually invisible. Most people won't notice your filling unless they're looking specifically for it. We pay particular attention to color matching for fillings on front teeth where appearance is especially important.
