How Cavities Develop

Your mouth hosts millions of bacteria, some of which feed on sugars and starches from your food. As these bacteria digest carbohydrates, they produce acids that attack your tooth enamel. Over time, repeated acid attacks weaken and dissolve the enamel, creating tiny holes that gradually expand into cavities.

Early cavities often don’t cause symptoms, which is why regular dental checkups are so important. Dr. Fernandez and Dr. Manzanares can spot decay in its earliest stages during routine examinations before you experience any pain or sensitivity. Catching cavities early means smaller fillings, less tooth structure removed, and a better long-term outcome for your tooth.

As decay progresses deeper into the tooth, you might notice sensitivity to sweet foods, hot or cold temperatures, or pain when biting down. These symptoms signal that the cavity has reached the inner layers of your tooth and needs prompt attention. Left untreated, decay spreads until it reaches the tooth’s pulp, causing severe pain and potentially requiring root canal therapy or even extraction.

The Filling Process

Getting a filling is a routine procedure that typically takes less than an hour. Dr. Fernandez starts by numbing the area around the affected tooth so you won’t feel discomfort during treatment. Once you’re comfortable, he carefully removes all the decayed tooth material using specialized instruments. This step is crucial—every bit of decay must come out to prevent it from continuing to spread under the filling.

After removing the decay, Dr. Manzanares cleans the prepared cavity thoroughly and shapes it to hold the filling securely. The following steps depend on which type of filling material you’re receiving, but the goal remains the same: seal the tooth completely to keep bacteria out and restore the tooth’s structure and function.

Modern anesthesia makes the procedure comfortable; most patients experience only minimal sensitivity afterward. Any discomfort usually fades within a day or two as your tooth adjusts to the new filling.

Composite Resin Fillings

Composite fillings, also called tooth-colored or white fillings, have become the preferred choice for most patients. These fillings use a mixture of plastic resin and fine glass particles that Dr. Fernandez can shade to match your natural tooth color exactly. The result is a restoration that blends invisibly with your smile.

Beyond aesthetics, composite fillings offer several functional advantages. The material bonds directly to your tooth structure, providing excellent support and strengthening the remaining tooth. This bonding process also allows Dr. Manzanares to preserve more of your natural tooth than other filling materials, because he doesn’t need to create special shapes to hold the filling in place mechanically.

Composite fillings work beautifully for front teeth where appearance matters most, but they’re equally effective for molars that handle heavy chewing forces. Modern composite materials are incredibly durable and resistant to wear.

Placement involves layering the composite material into the prepared cavity and using a special curing light to harden each layer. Dr. Fernandez carefully shapes and polishes the filling so it feels smooth and natural, matching the contours of your original tooth.

Amalgam Fillings

Amalgam fillings have served dentistry well for over 150 years and remain an excellent option for certain situations. These silver-colored fillings consist of a mixture of metals, including silver, tin, copper, and mercury. The mercury combines with the other metals to create a stable, durable compound extensively studied and deemed safe by major health organizations worldwide.

Amalgam’s main advantages are its exceptional strength and longevity. These fillings withstand tremendous biting forces, making them suitable for back molars. They’re also less technique-sensitive during placement, which means they perform reliably even in challenging conditions like areas that are difficult to keep dry during the procedure.

The gray appearance makes amalgam less desirable for visible teeth, but many patients still choose amalgam for back molars where strength matters more than aesthetics. These fillings typically cost less than composite options, which can be an important consideration when multiple teeth need treatment.

Dr. Fernandez places amalgam fillings by packing the pliable mixture into the prepared cavity, which hardens into a solid, durable restoration. The material expands slightly as it sets, creating a tight seal against the tooth walls.

Choosing the Right Filling Material

Both composite and amalgam fillings have their place in modern dentistry. Dr. Fernandez helps you decide which option suits your specific situation best by considering several factors: the tooth’s location, the size of the cavity, your budget, your aesthetic preferences, and whether you have any allergies to filling materials.

Composite fillings are usually the clear choice for front teeth and other visible areas because they’re virtually invisible. For large fillings in back molars, either material works well, though amalgam may offer slightly better longevity in high-stress situations. Some patients prefer to avoid amalgam entirely and choose composite for all their fillings, which is perfectly reasonable.

Dr. Manzanares takes time to explain the pros and cons of each option so you can make an informed decision that aligns with your values and needs.

Caring for Your Fillings

Dental fillings in Albuquerque can last many years with proper care. Composite fillings typically last seven to ten years, while amalgam fillings often last 10 to 15 years or longer. Good oral hygiene significantly extends the life of your fillings—brushing twice daily, flossing daily, and keeping up with regular dental checkups all help.

Avoid chewing ice, hard candy, or other extremely hard objects that could crack fillings or damage teeth. If you grind your teeth at night, Dr. Fernandez may recommend a night guard to protect your fillings and natural teeth from excessive wear.

Watch for signs that a filling might fail, such as sensitivity, rough edges you can feel with your tongue, or visible cracks. Contact our office if you notice any of these issues so Dr. Manzanares can evaluate and repair the filling before larger problems develop.

Prevent Future Cavities

While fillings repair existing decay, prevention keeps you from needing more fillings in the future. Limit sugary and acidic foods and beverages, brush with fluoride toothpaste, floss daily, and visit our office regularly for cleanings and checkups. These simple habits dramatically reduce your risk of developing new cavities.
