Dentists use fillings to replace tooth structure that is lost to decay. [1] X Research source Fillings protect your teeth and surrounding oral structure for up to 15 years, but they'll need to be replaced if they are broken, the margins aren't sealed, or there's recurrent decay under the filling. [2] X Research source Not replacing dental fillings can lead to chipped or fractured tooth, infection, or abscesses, and may harm the long term health of your tooth. [3] X Research source You can know if your dental fillings need replaced by looking for signs and symptoms at home and getting appropriate dental care.
Steps
-
Watch for tooth sensitivity. If you have fillings that need replacement, you’ll likely feel it first. Paying attention to the physical symptoms of old or decaying fillings can let you know if it’s time to have your dentist replace them. One sign that your fillings may need replacing is if you have tooth sensitivity to temperature, sweets, or pressure.

- Pay attention when you bite into any cold, hot, or sweet foods. You may feel momentary sensitivity or pain after they contact your tooth, which could be a sign of a filling needing replaced. [5] X Research source
- Be aware that your tooth may also be sensitive to touch either by your finger, toothbrush, or other dental tool.
- If you have sensitivity, use a fluoride toothpaste designed for sensitive teeth, like Sensodyne or Pronamel. [6] X Research source
-
Notice pressure when eating. In some cases, you may feel pressure when biting down on food. [7] X Research source This sensation may last for a few seconds or longer. This can signal a damaged filling or damage to your dental pulp. [8] X Research source
- Chew slowly if you detect any pressure when biting down on food. This may help you more easily identify which filling is potentially problematic.

Detect sharp or throbbing pain. In addition to pressure you may feel in a tooth, there may also be a sharp and throbbing pain. [9] X Research source It may come when you are eating or drinking or even when you’re not doing anything. Like pressure, the pain may go away quickly or linger for a few minutes. Noticing if you have any sharp or throbbing pain in a specific tooth or teeth can help you figure out if a filling needs replaced, especially if it happens with other symptoms. [10] X Research source
- Winter and cold air can also make your tooth more sensitive than usual indicating the need for a new filling.
-
Acknowledge a constant toothache. Some people who have fillings that need replacing may experience a toothache. [11] X Research source The pain may come and go or be constant. Toothaches are often caused by inflammation in the dental pulp, which can happen as a result of a filling needing replacement. If your toothache lasts longer than two days, see your dentist to prevent a complication with your dental health.

- If the pain lasts for too long, pulp can develop an irreversible pulpitis, which eventually leads to a necrosis where no pus is involved or an abscess.

-
Observe holes or dark spots. In addition to any physical sensations you may feel, you may be able to see signs that your fillings need replacement. One sign that your fillings may need replaced is seeing holes or dark spots. You may notice these while brushing or flossing your teeth every day. Paying attention for these signs can ensure you get prompt treatment and may minimize the risk of infection in your oral cavity.
-
Inspect floss for tears and food particles. If you floss your teeth daily, look at the floss in between each tooth. You may notice tears in the floss or pieces of food it may have removed. These can be signs of cracked teeth and/or a filling that needs replaced. [13] X Research source
- Note which tooth either shreds the floss or always seems to have food stuck in it. This can help your dentist better identify which filling needs replacement, but in cases like this an x-ray is almost always a must.
-
Feel the tooth surface for roughness. Most people love the feeling of clean and smooth teeth. You may notice that you have a tooth that never feels smooth even after brushing and flossing. This may be a sign that a filling needs replaced. [14] X Research source
- Keep an eye on the tooth and notice if anything makes the roughness worse or better. If it doesn’t get any smoother, let you dentist know.
-
Look for a broken, cracked, or lost filling. In some cases, you may be able to see when a filling needs replaced. If you notice any physical symptoms, check inside your mouth to see if you have any fillings that are visibly broken, cracked, or missing. Contact your dentist for an appointment to confirm that you need the filling replaced. [15] X Trustworthy Source Cleveland Clinic Educational website from one of the world's leading hospitals Go to source
- Wash your hands thoroughly with warm water and soap before putting them in or near your mouth. This can minimize your risk of introducing harmful bacteria into your mouth.
-
Identify chipped or fractured teeth. Even if you can’t see a problematic filling, a chipped or fractured tooth may also indicate that you need a filling replaced. If you have physical symptoms but can’t see any cracked, broken, or missing fillings, check the surrounding teeth. They may have chips or fractures that need the attention of your dentist. [16] X Research source
- Use your tongue to identify any sharp edges or missing structures. Food that gets stuck in daily is also a sign that your old filling needs replacement
- Be aware that cracks and chips may be so small that you can’t detect them with your eye alone. [17] X Trustworthy Source National Health Service (UK) Public healthcare system of the UK Go to source
- Wash your hands thoroughly with soap and water before looking for chipped or fractured teeth. This can prevent an infection.
-
Determine what kind of dental filling you have. There are different kinds of dental filling material. Each has a different life span. Knowing what kind of filling you have can help you know if it’s time to replace it. Recognize that the durability of the fillings also depends on how well you care for your oral health. If you take great care of your teeth and gums, then your fillings may last longer. The following are different types of fillings and their average life spans:
- Gold fillings, which can last for up to 15 years.
- Amalgam fillings, which are silver in color, can also last up to 15 years.
- Composite fillings, made of a material that matches your own tooth color, may need replacing after five years.
- Ceramic fillings can last about 7 years.

-
Schedule an appointment with your dentist. The only way to know for sure if a filling needs replaced is to see your dentist. A dental professional is also the only person qualified to replace fillings. If you notice any signs or symptoms of a filling that may need replaced, schedule an appointment with your dentist at the earliest time possible. This can ensure you get prompt treatment and may minimize your risk of developing abscesses. [18] X Research source
- Let the scheduling staff know why you need to see the dentist. They may be able to get you an appointment sooner rather than later.
-
Undergo an examination. Your dentist will conduct a thorough exam of your fillings to see if any need replacing. Let your dentist know any signs or symptoms you’ve observed, which he’ll consider along with your medical records and the results of his examination. [19] X Research source
- Be precise when explaining your symptoms of signs to the dentist. This can help your dentist better determine if the filling needs replaced. For example, “I get a sharp pain that hurts my entire tooth.”
- Allow your dentist to probe your mouth with a tool called an explorer. This will gently probe the tooth and filling to detect any worn spots.
-
Get additional testing. In some cases, a filling may be intact but still need replacement. This is because it has a small crack or is leaking. Both of these can lead to tooth decay. Your doctor may also want to check for problems between your teeth that are not visible with the naked eye. Your dentist suspects or determines that your fillings need replacing, they will likely have you undergo additional testing such as X-rays or trans-illumination. These can help your dentist better formulate a treatment and replacement plan for you.
- An X-ray is necessary to see if there's recurrent decay under a filling, or to see if the margins are opened on fillings that are between teeth. [20] X Research source
- Recognize that your dentist may also order a periapical radiograph, another type of oral X-ray, to check that the root of your tooth is not damaged. [21] X Research source
-
Discuss your replacement options. Your dentist may determine that you have one or more fillings that need replaced. If this is the case, explore your different options with the dentist. It may be possible to repair the old filling or you may need to have it completely replaced. Talking to your dentist about your different options can ensure you get proper care without the burden of cost or worrying that you’ll need to replace a filling in the near future.
- Ask your dentist if a different filling material may suit you better if an entire filling needs replaced.
-
Get regular checkups. Prevention is one of the best ways to keep your teeth and fillings healthy. Scheduling regular appointments with your dentist can help detect fillings that need replacement before they cause complications such as tooth or pulp decay.
