How long do cavity fillings take? If you’re worried about sitting in the dentist’s chair for hours, don’t be! Most cavity fillings take less than an hour, and in some cases, as little as 20 minutes. The exact time depends on the size of the cavity, the type of filling material, and whether you need multiple fillings.
If you’re getting a filling for the first time, you might wonder what happens during the procedure and how long it takes to heal. In this guide, we’ll walk you through everything you need to know—from how long a filling appointment lasts to what you can expect during recovery.
How Long Do Cavity Fillings Take? A Quick Answer
Most cavity fillings take between 20 minutes to 1 hour. A simple, small cavity might take only 20 to 30 minutes, while a bigger cavity or multiple fillings could take up to an hour or more. If you need a special filling like gold or porcelain, it may take multiple visits.
Dentists work quickly to make sure you don’t have to sit too long in the chair. After your filling, your tooth might feel a little different, but you can go back to your daily activities soon.
Step-by-Step: What Happens During a Cavity Filling?
- Numbing the area – The dentist applies numbing gel and gives an injection to prevent pain.
- Removing the decay – A drill or laser removes the damaged part of the tooth.
- Cleaning the cavity – The area is cleaned to remove bacteria and debris.
- Placing the filling – The dentist fills the hole with material like resin, silver, or gold.
- Shaping and polishing – The filling is shaped to fit your bite and polished for a smooth finish.
This process is usually painless, and you can eat and drink after the numbness wears off.
Types of Cavity Fillings & How They Affect Treatment Time
There are different types of fillings, and each takes a different amount of time to complete.
- Composite fillings (white fillings) – Take longer because they are applied in layers and hardened with light.
- Amalgam fillings (silver fillings) – Quicker to place but less natural-looking.
- Gold or porcelain fillings – Can take two visits because they are custom-made in a lab.
- Glass ionomer fillings – Used for kids and release fluoride to prevent cavities, but they are not as strong.
Choosing the right filling depends on cost, durability, and looks. Your dentist will help you decide what’s best.
How Long Do Different Types of Fillings Take to Set?
Each filling material sets differently, affecting how soon you can eat or drink.
- Composite fillings – Harden immediately with blue light, so you can eat soon.
- Amalgam fillings – Take 24 hours to fully harden, so avoid chewing hard foods.
- Glass ionomer fillings – Set quickly but need a little extra care.
- Gold and porcelain fillings – Bond instantly but require multiple visits.
Your dentist will tell you when it’s safe to eat and drink after your filling.
Do Kids Need More Time for Cavity Fillings?
Cavity fillings in children take about the same time as adults, but there are extra things to consider.
- Kids may struggle to sit still for 20-30 minutes, so some dentists use laughing gas.
- Numbing might take longer in children, adding time to the procedure.
- Recovery is usually quick, but they may feel discomfort for a few hours.
A good pediatric dentist will ensure the process is fast, smooth, and comfortable for your child.
Does the Size of the Cavity Change How Long It Takes?
Yes! The bigger the cavity, the more time it takes to fill.
- Small cavities – Quick, about 20 minutes.
- Medium cavities – Take about 30 to 40 minutes.
- Large cavities – May take over an hour and sometimes need multiple visits.
Regular dental checkups help catch cavities early so they can be filled faster and cause less trouble.
Can You Eat Right After a Cavity Filling?
You might be hungry after your dental visit, but be careful with what you eat.
- Avoid hot or cold foods until the numbness wears off.
- Skip hard and sticky foods for the first 24 hours.
- Eat soft foods like yogurt, soup, or mashed potatoes for comfort.
Your dentist will guide you on when you can return to normal eating habits.
How Long Does It Take for a Cavity Filling to Fully Heal?
Most people feel normal within a few hours to a day after a filling.
- Mild sensitivity or soreness can last a few days.

Taking care of your teeth will help your filling last for years.
