What Are Composite Fillings?
Composite fillings are tooth-colored restorations made from a blend of plastic resin and fine glass particles. They're used to repair teeth affected by cavities, chips, or cracks while maintaining a completely natural appearance. Unlike traditional silver amalgam fillings, composite fillings are virtually invisible once placed, and mercury-free.
At Tooth Bar, we use composite fillings as both a restorative and cosmetic solution. Whether you have a new cavity that needs treatment or old metal fillings you'd like replaced, composite provides a healthier-looking, mercury-free alternative that bonds directly to your tooth structure.
Who Are Composite Fillings For?
Composite fillings are appropriate for patients who need treatment for small to medium cavities. They are best for guests that desire a more natural look, and prefer mercury-free dental materials, or have chips or minor damage on visible teeth where appearance matters. Look better and feel better with natural restorations, that last.
Composite fillings are versatile enough for both front and back teeth. For very large restorations, your dentist may recommend an alternative like a porcelain inlay or crown for maximum strength and durability. Many offices use the same “white” material for all areas of the mouth, but at Tooth Bar, we have multiple shades and material choices to maximize aesthetics and function, depending on the patient's needs.
Benefits of Composite Fillings
The most obvious benefit of composite fillings is aesthetics. The material is shade-matched to your natural tooth color, so your filling blends in completely. No more self confidence due to dark spots when you smile big, or open your mouth wide to laugh.
Composite also bonds directly to your tooth structure, which means less of your healthy tooth structure needs to be removed during preparation, compared to amalgam fillings. This preservative approach keeps more of your natural tooth intact.
For patients replacing old amalgam fillings, switching to composite eliminates mercury-containing materials from your mouth — a priority for many health-conscious patients. And because composite bonds to the tooth rather than being wedged in mechanically, it can actually help strengthen a weakened tooth.
Our Composite Filling Process
Getting a composite filling at Tooth Bar is a quick, comfortable procedure. Your dentist begins by numbing the area with local anesthetic (for cavity treatment) or simply cleaning the existing filling site (for replacements).
Any decay is removed, and the tooth is prepared with a bonding agent. The composite resin is applied in thin layers, with each layer shaped and hardened using a special curing light. Once the final layer is in place, your dentist sculpts and polishes the filling to match the natural contours and bite of your tooth.
Most composite fillings are completed in 30 to 45 minutes. You can eat and drink normally once the anesthetic wears off.
Composite Fillings FAQs
How long do composite fillings last?
Composite fillings typically last 7–10 years or longer with good oral hygiene. Longevity depends on the size and location of the filling and your bite forces.
Are composite fillings as strong as metal fillings?
For small to medium cavities, composite fillings are very durable. For very large restorations on back molars, we may recommend stronger options like inlays or crowns.
Do composite fillings contain mercury?
No. Composite fillings are completely mercury-free. They're made from a biocompatible blend of resin and fine glass particles.
Can I replace my old silver fillings with composite?
Yes, and many patients choose to do so for cosmetic or inflammatory reasons. We can evaluate your existing fillings and recommend a replacement plan.
Will my insurance cover composite fillings?
Most dental insurance plans cover composite fillings. Coverage levels may vary, and some plans may cover composite at the same rate as amalgam. We'll help you understand your benefits and bill your insurer directly, as much as possible.
