Dental Fillings

What is a Dental Filling?

Dental Pearl will recommend a filling if you have a cavity caused by tooth decay. You may also need a filling after minor trauma, such as a chipped or cracked front tooth. When damage is more extensive, alternative treatments like dental crowns or dental bridges may be considered.

The purpose of a dental filling is to protect the tooth. The filling material helps strengthen the damaged tooth, restoring its shape and structure.

Once placed, you will be able to bite and chew without fear of the tooth crumbling or cracking further. If you need a front tooth filling, we can use a material that restores your appearance invisibly.

How Can I Tell If I Need a Filling?

Sometimes, the damage to a tooth is obvious, such as a crack or chip in a front tooth, or you might have noticed that a previous filling has begun to crumble. Otherwise, you may notice various symptoms, including:

• Increased tooth sensitivity, especially to temperature changes.
• Discomfort or pain when biting or chewing.
• Toothache.
• Rough edges on a tooth.
• Visible signs of a hole in a tooth.

Understanding the Different Types of Filling Materials

There are several materials used to fill teeth, and it is useful to understand what they are and when they are recommended, especially if there is more than one option that could be used to mend your tooth.

Some fillings are direct, meaning they are placed chairside and are fitted into the tooth immediately after it is prepared.

Others are indirect and made outside the mouth from a detailed dental impression of the tooth. These indirect fillings are made in a dental lab and may require a second appointment for fitting.

Direct Filling Materials

1. Amalgam fillings.
2. Composite resin fillings.
3. Glass ionomer fillings.

1. Amalgam Fillings

An amalgam cavity filling is silver-colored and made from a combination of several metals. These include tin, zinc, mercury, and copper. Amalgam is hard-wearing and cost-effective, but is less widely used. It has largely been replaced by newer, mercury-free materials that are virtually invisible.

2. Composite Resin Fillings

Most small to medium-sized cavities are likely filled with composite resin. A composite filling is made from tooth-colored resin, creating a natural-looking, nearly invisible restoration.

A composite dental filling is durable and biomimetic, meaning it is highly biocompatible and closely mimics natural tooth structure.

3. Glass Ionomer Fillings

A glass ionomer filling is used to mend cavities around tooth roots. This filling material is less durable but aesthetically pleasing. It can also slowly release fluoride, helping fight cavities.

Indirect Filling Materials

An indirect filling is used to fill larger cavities, usually those affecting the back teeth, and is called an inlay or onlay. Because it is made outside the mouth, a digital dental impression is needed.

1. Porcelain fillings.
2. Gold fillings.

1. Porcelain Fillings

Porcelain fillings are extremely strong and beautiful. The porcelain blends perfectly with your natural tooth color, creating an invisible restoration.

2. Gold Fillings

A gold filling is made from a gold alloy, which is polished to look good. Gold fillings are extremely durable but visible in the mouth.

What to Expect If You Need a Filling

Several steps are involved in placing a filling, but overall, the process is pretty quick. The overview below is for a direct filling.

1. Consultation and Digital X-Rays

Our dentist will need to examine the tooth to determine the extent of the damage and assess if a dental filling is appropriate. A digital dental X-ray provides further information about the depth of a cavity in a tooth or indicates how far a crack may extend into a tooth.

At this point, we can advise you of which type of filling you need and discuss suitable materials. You will receive a custom treatment plan outlining the available materials and the cost of the filling.

2. Tooth Preparation

The next stage is to prepare your tooth, starting with a local anesthetic to numb it. All the damage and decay are removed, and the tooth is shaped to receive the filling. Once ready, the tooth is thoroughly cleaned and disinfected and is ready to be filled.

3. Dental Filling Placement

The filling material is placed into the prepared cavity. Composite resin is hardened with light to help cure it and ensure a tight bond to your tooth.

Once all the filling material is in place, our dentist will shape and polish it, then check your bite.

Placing an Indirect Filling

If you need an indirect filling, we prepare your tooth and take a digital dental impression. Our dental lab uses this to create your filling. It may be possible to create it while you wait, so it is ready to fit soon afterward and can be bonded permanently onto your tooth.

Alternatively, we can place a temporary filling in the tooth using temporary cement. You will need to take care not to dislodge the filling, avoiding very hard or sticky foods that could pull it out or break it.

Once your new inlay or onlay is ready, we can try it in, check the fit, and bond it onto the tooth.

When Is a Dental Filling Not an Option?

Dental fillings are great when the damage is relatively minor and when much of the original tooth structure is still present. If you have more significant damage to a tooth, a filling may be inadequate.

You may need a different treatment to restore more strength to the tooth or to eliminate an infection. In this case, we may recommend:

• A dental crown to cover the tooth entirely.
• Root canal therapy to deal with any deep-seated infection.
• Tooth extraction, which is always the last resort after we explore every possible option.

How Long Will Fillings Last?

No restoration lasts forever, and the lifespan of your filling will depend on the material chosen.

• Glass ionomer fillings will last several years, but these are the most fragile.
• Composite resin fillings can last seven years or more.
• Amalgam fillings can last 10 years or longer.
• Ceramic and gold fillings can last 10 or 20 years or more.

Other factors affecting the lifespan of your filling include your oral hygiene routine, dietary habits, and the size of the filling.

Caring for Your Fillings

Looking after a dental filling is very straightforward, and you really don’t need to do anything different.

• Ensure that you brush at least twice daily and floss every day.
• Use fluoride toothpaste.
• Avoid using your teeth as tools or chewing anything very hard, like candies or popcorn kernels.
• If you have bruxism, a custom night guard can protect your teeth.

It’s very important to schedule regular dental exams and hygiene appointments. During these exams, we can check the condition of fillings as they can begin to leak when they age. Cleaning them professionally will help prolong their life.

Risks of Delaying a Filling

If you think you need a filling or have recently lost an old filling, it’s important not to delay treatment.

Delaying treatment allows the cavity to deepen, and you risk a severe tooth infection that may require root canal therapy and a crown afterward. Treatment costs are likely to be higher the longer you delay, and you are more likely to suffer a nasty toothache.
