How long does a filling take? In this article, we’ll break down everything you need to know about dental fillings, including the types, procedure, and how long the process typically takes.
What Is a Dental Filling?
A dental filling is a material used to restore a tooth that has been damaged by decay. When a cavity forms in a tooth, the decayed portion is removed, and the space is filled with a special material. Fillings not only help restore the tooth’s appearance but also prevent further decay from spreading.
There are several types of materials used for fillings, and the type of filling chosen depends on the size of the cavity, the location of the tooth, and the patient’s personal preferences.
Types of Fillings
Amalgam Fillings (Silver Fillings): Amalgam fillings are made from a blend of metals, including silver, tin, and copper. These fillings are durable and can withstand pressure from chewing, making them suitable for back teeth where the pressure is greatest.
Composite Fillings (Tooth-Colored Fillings): Composite fillings are made from a mixture of plastic and glass. They are tooth-colored, making them a great option for fillings in visible areas of the mouth. While composite fillings are less durable than amalgam, they are more aesthetically pleasing.
Ceramic Fillings: Ceramic fillings are made of porcelain and are more durable than composite fillings. They are also tooth-colored and resistant to staining. However, they can be more expensive than other types of fillings.
Glass Ionomer Fillings: Glass ionomer fillings release fluoride, which can help protect the tooth from further decay. These are often used for fillings in areas that are not under heavy chewing pressure, such as the edges of the teeth or in children’s teeth.
Resilon Fillings: A newer type of dental filling material, Resilon is made from thermoplastic polymer-based root canal filling material. It is used mainly for root canals, offering an alternative to traditional root canal treatments.
How Long Does a Filling Take?
The length of time it takes to get a dental filling can vary depending on several factors, including the size and location of the cavity, the type of filling material used, and the method the dentist employs. Here’s a breakdown of how long different types of fillings typically take:
1. Simple Fillings (Small Cavities)
If the cavity is small and located in an easily accessible area, the procedure can take anywhere from 20 to 30 minutes. This is typically the case for fillings in the front teeth where a composite (tooth-colored) filling is often used. The process involves numbing the area, removing the decay, and placing the filling.
2. Medium Fillings (Moderate Cavities)
For moderate cavities, which may be larger or in more difficult-to-reach areas, the procedure might take between 30 and 60 minutes. Dentists will need to remove more decay and may need to build up the filling to ensure it fits properly.
3. Large Fillings (Extensive Cavities)
When the cavity is large or deep, the filling procedure may take 60 to 90 minutes or longer. Large fillings often require more time because the dentist needs to remove a significant amount of decayed tissue. In some cases, the dentist may use a combination of materials, and the filling may require multiple layers.
4. Multiple Fillings
If you need more than one filling at the same appointment, the total time will increase accordingly. The time for multiple fillings can range from 90 minutes to 2 hours or more, depending on the number of cavities and the type of fillings required.
Factors That Affect the Time for a Filling
Several factors can influence how long the filling procedure will take, including:
1. Size and Location of the Cavity
The larger and deeper the cavity, the more time it will take to remove the decay and place the filling. Cavities in the back teeth may also take longer to treat because they are harder to access.
2. Type of Filling Material
Different filling materials require different processing times. For example, composite fillings (tooth-colored) require time to set and harden after placement, while amalgam fillings are placed and shaped more quickly. Ceramic fillings may require multiple visits because they are often made in a lab, while composite and amalgam fillings can be done in one visit.
3. Number of Fillings
If you are getting multiple fillings at once, the procedure will take longer. Dentists will need to focus on each cavity, ensuring that they are cleaned and filled properly.
4. Your Dentist’s Experience
An experienced dentist may be able to complete the procedure more quickly than a less experienced one. However, quality and precision should always come first.
What Happens During the Filling Procedure?
The process of getting a dental filling typically involves the following steps:
Step 1: Numbing the Area
Before the procedure begins, the dentist will apply a local anesthetic to numb the area around the tooth to ensure you don’t feel any pain. This may involve an injection or a gel that numbs the gums.
Step 2: Removing Decay
Once the area is numb, the dentist will use a dental drill, laser, or air abrasion to remove the decayed portion of the tooth. This process might take some time, especially if the cavity is large.
Step 3: Cleaning the Cavity
After the decayed tissue is removed, the dentist will clean the cavity to remove any bacteria and debris to ensure the filling adheres properly.
Step 4: Placing the Filling
Once the cavity is clean, the dentist will fill it with the chosen material. For composite fillings, the material is applied in layers and hardened using a special light. Amalgam and ceramic fillings may be shaped and placed directly into the cavity.
Step 5: Finishing Touches
The dentist will check the bite to make sure the filling fits correctly. If necessary, they will trim and polish the filling to ensure a smooth and comfortable surface.
Step 6: Post-Procedure Care
After the filling is placed, your dentist will give you instructions on how to care for your new filling. For example, you may need to avoid eating on that side of your mouth for a few hours if you have had a composite filling.
After the Filling: What Should You Expect?
Once the procedure is complete, you may feel some numbness in your mouth due to the anesthetic. The numbness typically wears off after a few hours, but you should avoid chewing on that side until you feel fully restored.
After the procedure, some people experience mild sensitivity to hot or cold temperatures. This usually goes away after a few days. If you continue to experience pain or discomfort, it’s a good idea to contact your dentist to ensure that the filling is properly placed.
