Fillings treat tooth decay, preventing further damage and tooth loss, as well as the possibility of pain and infection. A filling seals a hole, or cavity, in the tooth.
Having a cavity filled may cause some discomfort, but it should not cause pain. Anyone who experiences moderate or severe pain during or after the procedure should let their dentist know.
Below, we describe the materials in fillings and give details about the procedure, including how much it costs and when to contact the dentist afterward.
There are a few types of fillings, including:
Resin-based composite and glass ionomer fillings are less durable than amalgam fillings. However, they are also less visible and do not contain heavy metals.
The
Amalgam fillings may release low levels of mercury vapor, especially during a filling’s placement and removal. However, according to the
The FDA have concluded that exposure to mercury from fillings does not lead to adverse health effects in the general population, including people with multiple sclerosis, Parkinson’s disease, or Alzheimer’s disease.
Some may have a higher risk of experiencing negative effects of this vapor from amalgam fillings, however. This group includes people who:
Anyone concerned about the possible effects of amalgam fillings should discuss other options with their dentist.
In addition, the
Having a filling is typically an in-office procedure. Children and anyone with severe dental anxiety may require sedation or even general anesthesia. If a person needs to prepare for the procedure in any way, their dentist will let them know beforehand.
The steps may vary, depending on the filling’s location and the materials used. But the general steps are:
If they use a composite filling material, the dentist also needs to “cure,” or harden, it with a special light.
The dentist may recommend not eating or drinking until the numbing medication wears off. This is to prevent a person from accidentally biting their tongue or the inside of their cheek.
There may be some minor soreness or discomfort, and over-the-counter medication, such as ibuprofen (Advil, Motrin) or acetaminophen (Tylenol) should help.
Other times, pain may occur because the teeth do not fit together well due to the filling. This issue is called malocclusion, and the dentist should correct it to prevent further discomfort.
A person may experience increased sensitivity to hot and cold after a filling. This can occur due to minor nerve irritation, gum irritation, or inflammation due to the drilling.
These sensations typically improve with time. If they get worse instead of better, call the dentist. In some cases, the sensitivity can result from the shrinking of a composite filling.

A person who experiences any of the following should let their dentist know:
The cost of a filling depends on the location in the mouth, the material used, and the size of the cavity.
Medicare does not cover the cost of most dental procedures, including fillings.
States are required to provide dental care for children covered by Medicaid. Adults may also receive dental care under Medicaid, depending on their state’s policy.
To make the procedure more affordable, a person might also consider:
According to the American Dental Association (ADA), all fillings need to be replaced eventually. This is because the materials wear down due to eating, drinking, clenching, and grinding the teeth.
Worn or damaged fillings can be entry points for bacteria, leading to new tooth decay and possibly tooth loss. A person may not realize that their filling has worn down, which is one reason why it is important to visit the dentist regularly.
It is safe to have a cavity filled during pregnancy, according to the ADA, which also notes that pregnant people have an increased risk of gingivitis and tooth decay.
Overall, it is important to keep routine dentist appointments during pregnancy.
A dental filling treats tooth decay. Having a filling can prevent further damage, reduce the risks of pain and infection, and help maintain overall dental health.
There are different types of fillings, including amalgam, gold, composite, and glass ionomer. A person should discuss the options with their dentist.
After having a filling, a person may experience mild sensitivity or discomfort. Anyone who experiences more significant pain or sensitivity, or signs of an infection, such as a fever or swelling, should contact their dentist.
How long does the procedure take, and how much does it cost?
Depends on the size and location of the cavity, and the filling material used. Usually 20mins-1 hour and around $150-350.
