Do Composite Fillings Damage Teeth?

By Arcade Dental / May 10, 2024

A chipped tooth, a stubborn cavity – these dental woes can leave you yearning for a quick fix. In steps the trusty composite filling, a popular choice known for its natural-looking aesthetic. But amidst the talk of aesthetics, a question lingers: do composite fillings damage teeth?

This blog post delves into the world of composite fillings, exploring their composition, safety concerns, and potential impact on your oral health. We’ll debunk myths, address common anxieties, and equip you with the knowledge to make informed decisions about your smile.

What Are Composite Fillings?

Imagine a tooth restoration that seamlessly blends with your natural smile. That’s the magic of composite fillings. Made from a resin composite material – a blend of fine glass particles, acrylic resin, and other fillers – these fillings offer a significant aesthetic advantage over traditional silver amalgam fillings.

The placement process is relatively straightforward. After numbing the area and removing any decay, your dentist in Pharr, TX meticulously shapes the composite material to perfectly fit the cavity. Then, a special light cures the resin, solidifying the filling. This meticulous process ensures a natural-looking and functional restoration.

Are Composite Fillings Toxic?

Concerns about Bisphenol A (BPA), a chemical sometimes used in the manufacturing of dental composites, have sparked anxieties about the dental fillings‘ safety. However, the American Dental Association (ADA) assures us that the minimal BPA levels present in some composites pose no significant health risks.

Rigorous testing by the FDA ensures the safety and biocompatibility of dental materials. In fact, composite fillings are generally well-tolerated by the body, with a very low risk of allergic reactions.

Do Composite Fillings Damage Teeth?

Here’s some good news: composite fillings, when placed by a skilled dentist in Pharr, TX, are unlikely to damage your teeth. In fact, they can actually strengthen them!

The secret lies in the bonding process. Unlike traditional amalgam fillings that are simply wedged into the cavity, composite fillings create a strong bond with the surrounding tooth structure. This additional support can help prevent further cracks or fractures, especially in weakened teeth.

However, it’s important to remember that no dental restoration lasts forever. Improper care, excessive chewing force, or placement on large cavities can all contribute to chipping or fracturing of the filling.

What is the Survival Rate of Composite Filling?

The longevity of a composite filling depends on several factors, including:

  • Placement Technique: A skilled dentist ensures a proper fit and bond, maximizing the filling’s lifespan.
  • Location of the Filling: Fillings placed on back teeth endure more chewing pressure and may wear down faster.
  • Oral Hygiene Habits: Brushing and flossing regularly removes plaque and bacteria, preventing decay that can undermine the filling.
  • Diet: A diet rich in sugary or acidic foods can accelerate wear and tear.

With proper care, composite fillings can last anywhere from 5 to 15 years.

What is the Safest Filling for Teeth?

Both composite and amalgam fillings have their pros and cons.

Composite Fillings:

  • Pros: Excellent aesthetics, bond to tooth structure, less tooth removal required.
  • Cons: May not be as durable as amalgam, slightly higher cost.

Amalgam Fillings:

  • Pros: Highly durable, lower cost.
  • Cons: Dark, metallic appearance, may require more tooth removal for placement, potential for low-level mercury exposure (though the ADA considers this safe).

Ultimately, the “safest” filling material depends on your individual needs and priorities. Discuss your options with your dentist, considering factors like the location and size of the cavity, your budget, and your aesthetic preferences.

A Bottom Line

Composite fillings offer a safe and aesthetically pleasing solution for restoring damaged teeth. While they may not be invincible, proper care and good oral hygiene habits can significantly extend their lifespan.  If you’re looking for a natural-looking and biocompatible filling material, composite fillings are a strong contender.  However,  the best choice for you depends on your individual needs and circumstances.  Always discuss your options with your dentist to make an informed decision that promotes optimal oral health.


Can I feel pain after getting a composite filling?

    There might be some mild sensitivity after the filling placement, especially to hot or cold temperatures. This usually subsides within a few days. If you experience persistent pain, consult your dentist.

    Do composite fillings look natural?

      Yes! Composite fillings can be color-matched to your natural teeth, ensuring a virtually undetectable restoration.

      Are composite fillings more expensive than amalgam fillings?

        Generally, yes. However, the cost can vary depending on your location, dentist, and the complexity of the procedure.

        Can I get composite fillings if I have allergies?

          While composite fillings are generally well-tolerated, some people might be allergic to specific components. Discuss any allergies with your dentist before the procedure.

          What happens if my composite filling breaks?

            Don’t panic! A chipped or broken composite filling can be repaired relatively easily. Contact your dentist to schedule a repair appointment.
