Reasons to Have One, What to Expect, Associated Risks & More

5 Reasons Why You Would Need Dental Fillings

1. Cavity

Dental fillings are most often used to fill cavities or areas where the tooth has decayed.[1] The filling is used to fill the hole left behind after the decayed part of the tooth is removed.

2. Worn teeth

A filling can also be used to fix teeth that have been worn down over time. This usually happens because of a bad habit, such as tooth grinding or biting one’s nails.[1] Other treatments can also be used to make sure you don’t continue the habits that led to your worn teeth.

3. Broken teeth

If your tooth becomes cracked or broken, a dental filling may also be an appropriate treatment option. Cracked or broken teeth can sometimes occur as the result of an injury to the mouth or from biting down on something hard. Cracking or breaking your teeth is more common than many people realize, as teeth are not indestructible.

4. Pulpitis

Reversible pulpitis, also known as endodontal disease, can also require the need for a filling. This occurs when the nerves and/or pulp inside the teeth become infected, which can sometimes be the result of a cavity. Removing the infected tissue and replacing it with a filling will sometimes treat mild versions of this disorder.

5. Pain and/or sensitivity

If you’re not sure what the issue is with your tooth but are experiencing pain and/or sensitivity, a filling might be necessary.[2] This includes any kind of pain localized to a certain area, sensitivity when drinking or eating cold or hot items, tingling feelings, or discomfort. If you’re experiencing any or all of these symptoms, make an appointment with your dentist to examine the tooth. They might find that one of the above issues has occurred, which will cause them to treat your tooth with a dental filling.

Understanding Dental Fillings

1.Types of Dental Fillings

There are several different types of dental fillings.[3] Silver amalgam fillings are 50 percent silver, zinc, tin, and copper combined with 50 percent mercury. Composite fillings are made from a mixture of plastic and resin that is the same color as the tooth. This kind of filling is placed into the cavity when it is soft and then hardened with a curing light. Ceramic fillings are made of porcelain, and they look the most like regular teeth. Glass ionomer fillings are usually made for children because they still need time for their teeth to grow and change. Gold fillings less commonly used, because although they are sturdy they are also more costly.

2. How a cavity is filled during the procedure.

First, the dentist will give you a shot of a local anesthetic in your mouth and/or gum so you won’t feel the drill or any other instruments used, although you will be awake during the procedure. A dental assistant will also be present.

Next, the dentist will remove the decayed material using a drill, laser, or air abrasion instrument.[1] They will test to make sure all the decayed area and debris have been removed before continuing.

After filling the tooth with one of the filling types listed above, they will usually polish the tooth as a last step in order to make sure its entire surface is smooth and not rough or uncomfortable. After polishing, they will test your bite to make sure all your teeth are aligned properly.

Risks of Getting Dental Fillings

1. Wear and tear

All fillings types have different lifespans, and your own behavior can affect how long a dental filling is likely to last. Consistent grinding, jaw clenching, chewing, and biting can eventually cause your dental fillings to wear down. They might also become chipped or cracked over time.[1] In order to be aware of this issue as soon as possible, it’s important to see the dentist on a regular basis.

2. Further decay

Sometimes the seal between the filling and your tooth’s enamel can break apart. This can make room for bacteria to get through, and the tooth, which has already experienced partial decay from an initial cavity or issue, will start to decay even further. This can sometimes lead to pulpitis or an abscessed tooth.[1]

3. Complications from going untreated

Though a filling can sometimes be less strong than a regular tooth or cause some complications, it is much worse to let a cavity or another issue that requires a filling go untreated. Untreated cavities can lead to tooth fractures, bone loss, infection, abscesses, and an inability to bite down due to pain.[4]

What to Expect with Dental Fillings

1. Different fillings, different results

There are many different types of fillings, and they all yield different results. Composite fillings are the same color as teeth, so they look more natural than silver fillings, but they are more expensive and don’t last as long.[5] Gold fillings are extremely durable, but they are very expensive and do not blend in well with your other teeth.

2. Home dental care

No matter what type of filling you choose, it will not be indestructible. This means you will need to take care of your teeth at home. Brush twice a day, floss daily, and chew carefully. Also, make sure that if you have a chronic issue that led to your need for a dental filling, such as tooth grinding, you talk to your doctor about how to deal with it (e.g., wearing a mouth guard).
