Getting a cavity filled is a routine procedure, but it’s helpful to know what to expect beforehand. A lot of people wonder, “Just how long do fillings take?”
Understanding the factors that influence the appointment length can help you prepare and manage your expectations. This article will break down the average time for a filling, what might affect that timeline, and what you can expect during and after the procedure. We’ll cover everything from the filling material used to potential complications.
How long does it take to get a cavity filled?
Most fillings take between 20 and 60 minutes, start to finish. But a lot of factors influence the total time.
When you schedule your appointment, the office will likely set aside 30 to 60 minutes for the procedure. However, the actual time needed depends on:
- The size of the cavity
- The location of the cavity
- The type of filling material used
- Whether you get anesthesia
Complex cavities may need extra procedures, like pulp capping or even a root canal, which will take more time.
What factors affect how long fillings take?
A simple filling may take only 20 minutes, but more complex scenarios can take longer. The time needed to fill a cavity can vary based on factors such as:
Size and complexity of the cavity
Larger cavities take longer because the dentist has to spend more time removing decay and placing the filling. If the cavity is deep and close to the nerve, the dentist may need to add a step called pulp capping to protect the nerve. Also, if the cavity affects multiple surfaces of the tooth, that will add to the time, since it requires more material and precise shaping.
Number of fillings needed
If you need multiple fillings, that will extend the overall time you spend at the dentist’s office. The dentist may prioritize which fillings to do first based on how severe they are and where they’re located in your mouth.
Type of filling material
Different filling materials have different setting times and application techniques. Composite fillings may need to be applied in layers and then cured with a special light. Amalgam fillings involve mixing the material and packing it into the cavity.
Need for anesthesia
Applying local anesthesia adds about 5 to 10 minutes to the appointment. The dentist needs to make sure the area is fully numb before starting the procedure. Fillings for children may take longer because of the time it takes for the anesthesia to take effect. Some patients may need additional numbing medication to get comfortable.
A Step-by-Step Cavity Filling Timeline
So, what should you expect when you go in for a filling? Here’s a general timeline:
- Preparation (10-15 minutes): Your dentist will look at the tooth and the area around it. They may also take X-rays to see how bad the decay is and to make sure there aren’t any other problems.
- Anesthesia (5-10 minutes): They’ll numb the tooth and the nearby tissues with local anesthesia.
- Isolation (2-3 minutes): The dentist may use a rubber dam to keep the tooth dry during the filling.
- Decay Removal (5-15 minutes): Using a drill or other tools, the dentist will carefully get rid of the decayed part of the tooth.
- Cleaning and Disinfecting (2-3 minutes): To kill any remaining germs, the cavity will be cleaned and disinfected.
- Filling Placement (5-15 minutes): The dentist will fill the cavity with a filling material and shape it to fit the tooth.
- Polishing and Bite Check (5-10 minutes): The filling will be polished to make it smooth, and the dentist will check your bite to ensure it’s aligned correctly.
After the filling: care and sensitivity
It’s normal to have some sensitivity in the filled tooth for a few days or weeks. Try to avoid very hot or very cold foods and drinks during this time.
Also:
- Chew on the opposite side of your mouth until the filling feels normal.
- Be gentle when you brush and floss around the filling.
- Use toothpaste made for sensitive teeth if you continue to feel sensitivity.
If your tooth remains sensitive or painful for more than a few weeks, call your dentist’s office.
Conclusion
Although most fillings take between 20 and 60 minutes, several variables can affect the amount of time you’ll be in the dentist’s chair. Knowing what these factors are can help you plan for your appointment and know what to expect.
Before your appointment, be sure to let your dentist know if you have any questions or concerns. Choosing an experienced dentist who focuses on making patients comfortable is also important.
By understanding what’s involved in getting a filling and following your dentist’s aftercare instructions, you can make sure your filling is a success and that your teeth stay healthy for years to come.
