Tooth-colored fillings offer aesthetics and durability for your healthy smile.

Tooth-Colored Fillings in Wellesley

Dr Cao explaining a treatment to a patient One of my primary goals at Wellesley Hill Dental is to help you avoid common dental concerns like tooth decay and gum disease. However, the reality is that most of us will need a tooth repaired at some point, and if we can detect decay early, I can usually treat it with a dental filling.

I recommend fillings for small areas of tooth decay. I use tooth-colored composite resin for seamless, aesthetic dental fillings that don’t detract from the beauty of your smile. Composite fillings also provide the durability you need for comfortable and effective chewing function.

What Are the Benefits of Composite Resin Fillings in Wellesley Hills?

Tooth-colored composite fillings offer several advantages over metal amalgam fillings, which are the primary reasons I recommend them to my patients. Here are some things you should consider.

Tooth Structure

Composite fillings allow me to preserve more of your natural tooth during placement.

Aesthetics

Tooth-colored fillings provide superior aesthetics over metal fillings, which are visible in your smile.

Temperature Changes

Composite resin doesn’t react to temperature changes in the mouth like metal amalgam.

Versatility

I can use composite resin material for other cosmetic repairs with dental bonding.

Durability

When I directly bond the filling to your tooth, it provides strength and durability.

Frequently Asked Questions

I'm often asked about the durability of tooth-colored (composite) fillings in Wellesley, MA compared to traditional metal (amalgam) fillings. The great news is that modern tooth-colored fillings have come a long way and are now an excellent, durable option for most patients.

Composite fillings are made from advanced materials that have significantly improved in strength and longevity over the years. While metal fillings were once considered the gold standard for durability, today's tooth-colored fillings can last 7 to 10 years or even longer with proper care. Composite fillings offer several advantages beyond aesthetics.

Strengthening Your Tooth and Enhancing Aesthetics

The composite material bonds directly to your tooth, helping strengthen its structure and providing additional support. Unlike metal fillings, these tooth-colored alternatives don't expand and contract with temperature changes, reducing the risk of microscopic cracks or tooth weakening over time.

I typically recommend tooth-colored fillings in Wellesley Hills Dental for most of my patients because they're durable and more aesthetically pleasing. They blend seamlessly with your natural tooth color, making them virtually invisible when you smile or speak. Additionally, they require less tooth preparation, meaning we can preserve more of your natural tooth structure.

Of course, the longevity of any filling depends on factors like oral hygiene, diet, and individual wear patterns. During your checkups, we'll monitor your fillings and ensure they continue to protect your dental health. Contact our Wellesley Hills Dental team at (781) 237-6511 for more information.

Although the tooth-colored composite resin we use for fillings is long-lasting and durable, the truth is that it can discolor over time, especially if you don’t practice good oral hygiene.

Tooth-colored fillings can become slightly porous over time, and they’ll wear down gradually when you bite down and chew.

What Causes Discoloration?

There are several ways that your tooth-colored filling can get stained or discolored, including the following:

Food and drink — Coffee, tea, red wine, berries, and dark sauces can penetrate the resin and cause discoloration.
Tobacco use — If you smoke or use tobacco products, it can lead to yellow or brown stains on your composite filling.
Age and wear — After a few years, your filling is more susceptible to plaque and bacteria buildup, leading to stains.
Broken seals — Sometimes, a very small gap forms between your tooth and your filling; if this happens, stains can appear in those gaps.

The Dental Filling Process

Once we’ve identified decay in your tooth, the quicker we can treat it, the easier, less costly, and minimally invasive the treatment will be.

If decay is ignored or undiagnosed, it progresses further into your tooth and causes more damage. Eventually, this could even lead to an uncomfortable tooth infection or dental emergency. If this happens, you will likely need more complex treatment to restore your tooth and dental health.

Here’s what to expect when we complete a dental filling:

Diagnosis — Determining which tooth and where the areas of decay are.
Anesthetic — I deliver dental anesthetic so your tooth is numb and you don’t feel anything during the procedure.
Eliminating decay — I carefully clean the decayed areas of your tooth before applying composite resin.
Customization—I will custom-shade the composite resin to match the shade of your tooth so that it is not noticeable after completion.
Application — I apply the moldable filling material to your tooth and cure and harden it with a special light.
Polishing — Finally, I shape the filling to the anatomy of your tooth, adjust it for your bite, and polish it for a beautiful, natural-looking finish.
