Temporary fillings are exactly what they sound like: short-term solutions your dentist uses to protect a tooth until a more permanent fix is ready. They offer protection and can relieve pain, but they’re not designed to last forever.
So, how long does a temporary tooth filling last? Well, that depends on a few things. We’ll go over the typical lifespan, the factors that can affect it, how to care for your temporary filling, and when you should definitely see your dentist.
It’s important to remember that temporary fillings are temporary. Don’t skip that follow-up appointment!
What is a temporary filling and why is it needed?
A temporary filling is just what it sounds like: a short-term fix for a tooth that needs a little help.
These fillings are made from materials that are softer than the materials used in permanent fillings. They’re used as an interim solution during various dental procedures, such as after a root canal, before a crown is placed, or when your dentist wants to keep an eye on the tooth for a while.
Temporary fillings are often needed to:
- Protect the tooth enamel and other structures from damage caused by bacteria
- Offer some pain relief until your permanent filling or crown can be placed
- Provide a seal after a root canal procedure
How long will a temporary filling last?
Most temporary fillings will last for about 6 to 8 weeks, but some can last for a few months.
How long your filling lasts depends on several things:
- The material it’s made of. Some materials are more durable than others. Zinc oxide eugenol (ZOE) is a common material.
- Where it is in your mouth. Fillings in areas that get a lot of chewing action, like your molars, may not last as long.
- Your oral hygiene. If you aren’t brushing and flossing, your filling is more likely to fail.
- Your habits. Grinding your teeth or chewing on hard things can damage it.
Temporary fillings aren’t meant to last because they’re made of weaker stuff and your dentist needs to be able to take them out easily when it’s time for the permanent filling.
Signs your temporary filling needs attention
Because temporary fillings are not meant to last, it’s important to monitor them for any signs of wear and tear. If you notice any of the following, contact your dentist.
- Chipping or cracking: Look closely at the filling to see if you can spot any fractures or missing chunks.
- Dislodgment or looseness: Does the filling move when you chew or touch it?
- Sensitivity to temperature or pressure: Does the tooth hurt when you drink something hot or cold, or when you bite down?
- Pain or discomfort: Do you have a constant or occasional toothache near the filling?
- Changes in bite: Does your bite feel different or uneven?
- Foul taste or odor: Do you notice a bad taste or smell coming from the filling? This could indicate a bacterial infection.
Caring for Your Temporary Filling
Temporary fillings are more delicate than permanent ones, so you’ll want to take extra care to protect them. Here are a few tips to help your temporary filling last as long as it needs to.
Oral hygiene practices
- Brush gently. When brushing, take extra care around the filling to avoid dislodging it.
- Floss carefully. Ditto for flossing. Be gentle around the filled tooth, and don’t apply too much pressure.
Dietary considerations
- Avoid hard or sticky foods. Hard and sticky foods are more likely to damage or dislodge your filling.
- Chew carefully. It’s best to chew on the opposite side of your mouth, if possible.
- Eat soft foods. Softer foods are less likely to dislodge a temporary filling, so choose soft foods for a day or two after the filling is placed.
Habits to avoid
- Don’t chew gum. Gum is sticky and could pull out your filling.
- Don’t probe at the filling. It may be tempting, but avoid touching or probing the filling with your tongue or other objects.
- Avoid biting fingernails or other hard objects. This is good advice at any time, but it’s especially important when you have a temporary filling.
What happens when it’s time to get a permanent filling?
Removing a temporary filling is usually fast and doesn’t cause pain. Your dentist might scrape it away or use a drill. In some cases, they may numb the area first with a local anesthetic.
When you get your permanent filling, talk to your dentist about the different materials you can use. Composite, amalgam, gold, and porcelain are all options. Your dentist will ensure that the filling fits well and that your bite feels normal.
Final Thoughts
Temporary fillings are a lifesaver, but they’re not meant to last forever. With diligent care, you can extend the life of a temporary filling, but it’s crucial to see your dentist for a permanent solution.
Don’t delay getting a permanent filling! A temporary filling is no match for tooth decay or a painful infection.
