Dental Fillings & Composites: Restoring Your Smile with Esthetics and Strength

Have you noticed a small dark spot on a tooth or felt a sudden sensitivity when drinking something cold? These are often the first whispers of a cavity. Ignoring them can lead to pain, but treating them early is simple and effective. In the world of modern dentistry, we have moved far beyond the unsightly silver fillings of the past. Today, we focus on composite resins—tooth-colored dental fillings that blend seamlessly with your natural smile.

This topic is vital for everyone, whether you are a local resident here in Quito or a traveler passing through our beautiful city. Dental health doesn’t take a vacation, and knowing your options is the first step to a healthy mouth. In this article, I will provide a complete explanation of dental composites, including why they are essential for structural integrity, how the procedure works, and answers to the most common questions to put your mind at ease. At Centro Odontológico Asiri, we believe that pain is not an option, and we are here to guide you toward a healthy, beautiful smile.

Key Takeaways

1. Aesthetic Integration: Modern composite resins are designed to mimic the natural color and translucency of your teeth, making the restoration virtually invisible to the naked eye.
2. Conservative Treatment: Unlike older techniques that required removing healthy tooth structure, composites bond directly to the tooth, allowing us to preserve as much of your natural tooth as possible.
3. Prevention of Further Damage: Treating a cavity early with a high-quality filling stops decay in its tracks, preventing root canals or extractions down the line.

What are Dental Fillings (Composite Resins)?

In dentistry, a “filling” is a treatment used to restore the function, integrity, and morphology of missing tooth structure resulting from caries or external trauma. While there are different materials available, at Asiri, we prioritize Composite Resins. These are tooth-colored plastic and glass mixtures used to restore decayed teeth.

Colloquially, you might hear these referred to as “white fillings.” They are versatile and can be used not just for treating decay, but also for cosmetic improvements of the smile by changing the color of the teeth or reshaping disfigured teeth. This aligns with our mission to provide high aesthetics and quality of life.

The material is soft and malleable when applied, allowing us to sculpt it perfectly to the shape of your tooth. Once shaped, it is hardened using a specific blue light, creating a durable restoration that supports the remaining tooth structure.

Why is this important?

The importance of high-quality dental fillings extends beyond just “fixing a hole.” From a health perspective, sealing a cavity prevents bacteria from penetrating deep into the nerve of the tooth, which can cause severe infection and pain and the need of a root canal treatment.

From a structural standpoint, composites bond to the tooth walls. This chemical bond actually reinforces the tooth, making it less prone to fracture compared to teeth filled with non-bonding materials like amalgam (silver). Furthermore, for our patients who value aesthetics, composites ensure that your laugh remains bright and natural, without dark spots showing your dental history.

Procedure

At Centro Odontológico Asiri, we treat you with delicate care. Here is what you can expect:

• Diagnosis: We use precise diagnostics to determine if a filling is what you truly need, ensuring honesty and responsibility in our recommendations.
• Anesthesia: If necessary, we numb the area to ensure you feel absolutely no pain.
• Preparation: We carefully remove the decayed portion of the tooth using sterile instruments.
• Bonding: A gel is applied to micro-etch the tooth surface, followed by a bonding agent to ensure the filling sticks securely.
• Layering: We place the composite resin in layers, hardening each layer with a specialized curing light.
• Shaping and Polishing: Dr. Casal or our specialists will trim the composite to fit your bite perfectly and polish it to resemble the sheen of natural enamel.

Benefits

• Natural Appearance: The composite comes in various shades to match your own teeth perfectly.
• Versatility: It can repair chipped, broken, or worn teeth, not just cavities.
• Bonding: It chemically bonds to the tooth structure, providing further support to the tooth.
• Spare Tooth Structure: Less healthy tooth needs to be removed compared to amalgam fillings.
• Mercury-Free: Unlike silver fillings, composites contain no mercury.

Potential Risks and Complications

• Post-operative Sensitivity: Some patients may feel mild sensitivity to hot or cold for a few days after the procedure.
• Discoloration: Over many years, like natural teeth, composites can pick up stains from coffee, tea, or tobacco.
• Wear and Tear: While durable, they may wear down over time in patients with heavy grinding habits (bruxism).

Alternatives

• Inlays/Onlays: For larger cavities, a laboratory-made porcelain filling is stronger and more durable.
• Dental Crowns: If the decay has destroyed a large portion of the tooth, a crown (or cap) may be necessary to save it.
• Silver Amalgam: An older material, though we do not recommend it due to aesthetic and conservation concerns.

How long do fillings last?

Fillings last years but there are a lot of variables to consider, from your point of view, the most important is the regular checkup¹

How Much Does a Dental Filling Cost in Ecuador?

The price of a filling depends on different variables that you must consider to ensure that your dental restoration is going to be durable and most importantly: safe.

The Size of the Cavity:

Here we talk about the number of faces of the tooth that are affected by caries.

• Simple: caries occupies only one face of the tooth
• Composite: cavity occupies two faces of the tooth
• Complex: caries occupies 3 faces of the tooth
• Large build-up: there are 3 or more affected faces, in these cases we are already talking about dental reconstructions or onlays.

Technique Used:

The cost of the filling also depends on the techniques used, the more care is taken, for example, working with absolute insulation to avoid any type of contamination and thus improve the safety and quality of the filling.

There are also techniques that allow us to reduce and sometimes even eliminate the use of the turbine or drill through the use of special materials that dissolve or soften the decay so that it can be removed without the need for a drill.

If the decay is very deep, a Deep Margin Elevation or clinical crown lengthening may need to be performed beforehand.

You can also opt for conscious sedation during dental treatments in which a certified anesthesiologist takes the patient in a controlled manner to a state where they will be sedated and will not remember anything or hear the sounds of the drill, eliminating discomfort that may cause anxiety or fear.

Materials Used

As we discussed earlier, there are different qualities of the material to be used in a dental restoration and its success may depend on this.

In general terms, a filling in Ecuador costs from $30. That is, using the best materials and techniques to guarantee a quality, safe and reliable result.
