Nobody wants holes in their teeth. Whoever does is a strange person.
A cavity is just one of the consequences of bad oral health. It can be painful, it’s inconvenient, and it can cost money you could have saved by just brushing and flossing every day.
What Is A Cavity Filling?
A cavity is when the hard surface of your tooth is damaged and that damage develops into a hole. Basically, a cavity is tooth decay. This is often caused by bacteria, which builds up from eating unhealthy food and not caring for your teeth properly.
Symptoms typically happen when a cavity is more developed, so you may not notice a cavity until it’s too late. However, if you catch a cavity early, you may be able to reverse the tooth decay and it may not be necessary to fill the cavity.
Here are the most common signs of a cavity:
- Tooth pain, usually happening for no apparent reason
- Sensitive teeth
- Moderate pain when you eat or drink
- Visible openings in your teeth
- Discoloration of the surface of a tooth (brown, black, or white)
A cavity filling is when the dentist fills the hole in your tooth with some sort of material. The hope is to get rid of your symptoms and make the tooth more aesthetically pleasing.
Types Of Cavity Fillings
Most people may think a cavity filling is just a cavity filling, but there are actually a few different types you can get.
Amalgam is one of the longest-used and most-researched materials for cavity fillings. It’s a very strong material made of several metallic ingredients, meaning their great for fillings. Although they can be visible when you smile, they’re also the most affordable option.
Composite fillings are made of a combination of plastic-type materials, and can be customized to be the same color as your teeth for aesthetics. These are best suited for smaller or mid-sized cavities in teeth that do a good amount of chewing.
Metal fillings are usually made up of gold or silver, gold costing about 10 times more than silver. The upside to gold fillings is that some people like the look of them better. Plus, gold and silver amalgam fillings can last between 10 and 15 years.
Ceramic fillings are usually made of porcelain and have the same color as your natural teeth. However, many people pass up these types of cavity fillings because they can cost about as much as gold fillings.
Glass lonomer is a type of composite filling and they release fluoride to help protect the teeth.
Cavity Filling Procedure Step-By-Step
Before your dentist fills a cavity, they’ll speak to you before the procedure. However, it’s a good idea to know what to expect before you even visit the dentist’s office.
How Do Dentists Fill Cavities?
After that, they’ll need to scrape off the decayed part of the tooth. Then they will sterilize the area, especially the cavity, and prep the hole for the filling.
They will then fill the cavity with whatever material you and your dentist decided on beforehand. After it’s filled, the dentist will buff and refurbish the surface the tooth.
Your mouth will probably stay numb from the anesthesia for a few hours afterwards.
How Long Does It Take To Fill A Cavity?
This whole process can take about an hour. And that includes getting X-rays before the procedure, speak with you about the procedure, and then do the procedure.
How Long Does Cavity Filling Last?
The length of time that a cavity lasts depends mainly on the material of the filling, but also on how well you take care of it (more on that later).
For example, glass ionomer fillings last a few years while metal fillings can last up to 15 years. On average, a typically filling will last between 7 and 10 years.
Cavity Filling Pain
During and directly after the cavity filling, you shouldn’t have any pain because of the anesthesia. However, as that wears off, you may begin to feel some discomfort. Your dentist will probably give you pain medications for this.
Other reasons could include a cracked tooth or loose filling, which would be unfortunate, but it is possible. The most likely reason a filling could hurt is if, after the new filling, your bite is off a little, at which point you’ll most likely go back to your dentist so they can adjust the bite. So if the dentist didn’t fill the cavity correctly, you could be having pain. This is one reason to make sure you find a great dentist — you can do so with our Find A Dentist tool.
Cavity Filling Aftercare
Obviously, you should keep up good oral hygiene after getting a cavity filled. This means brushing twice a day, flossing, and visiting your dentist about twice a year.
Discomfort in the following days in normal, but if your tooth continues to be sensitive, if you feel a sharp edge to the tooth, if there’s a visible crack in the filling, or if part of the filling is missing, call your dentist.
As far as your diet, you’ll want to avoid hard and sticky foods and candies for at least 24 hours after the procedure as they can crack or dislodge your filling. This is especially true of amalgam fillings.
Cavity Filling Cost
Cavities can cost a lot, just like any dental procedure. But just how much does it cost to fill a cavity?
A cavity filling without insurance can be hundreds or thousands of dollars, depending on the type of filling you get. Here’s a cost breakdown of the most common types of fillings:
- Metal filling: $50 to $150 for one to two teeth, $120 to $300 for more
- Natural-colored resin fillings: $90 to $250 for one to two teeth, $150 to $450 for more
- Porcelain fillings: $250 to $4,500
However, if you were to get dental insurance, the insurance company may be able to cover anywhere between 50% and 80% of the total cost.
Price Of A Cavity Filling With A Dental Discount Plan
Dental discount plans are also a great alternative, and sometimes an addition, to dental insurance.
As an example of how much you could save, let’s take the above mentioned prices of cavity fillings. Say you have to get a cavity filling and it’s going to cost $300 and you don’t have insurance.
With a dental discount plan, you could get a discount of up to 60%, which, in this example, would save $180 and you’d end up spending just $120.
Cavity Filling FAQ
Just to be sure you’re as prepared as possible for getting a cavity filling, here are some commonly asked questions and answers.
Can you get a cavity filled while pregnant?
Yes, depending on the type of anesthesia the dentist uses. If it’s a local anesthetic like Lidocaine (which it usually is), it is safe to receive while pregnant. The FDA classifies it as a category B drug, meaning it’s safe for both you and the baby.
However, if it’s IV sedation or general anesthesia, it may not be safe. It’s best to take your dentist’s advice.
Can a baby get a cavity filling?
Yes, definitely. Baby teeth actually stay in a child’s mouth for 12 to 13 years, and if you don’t fill cavities that form, the teeth can become infected. This will only lead to more tooth decay.
Do small cavities need to be filled?
Sometimes. If it’s small enough, you may not need to get it filled. If you catch the tooth decay (i.e. cavity) early enough, you may be able to treat it without a filling. However, you should see your dentist so they can examine it.
How many cavities can you have filled at once?
As many as you need and as many as your dentist is willing to place. It really depends on how long you can be at the dentist, how long can you have your mouth open without becoming uncomfortable, and how much anesthesia can you receive in a short amount of time. These are factors you can discuss with your dentist beforehand.
Is it possible to fill a cavity at home?
Possible? Yes. A good idea that’s safe and efficient? No.
You should really avoid a DIY cavity filling at all costs. It’s best to see a dental professional so as to minimize the potential issues and complications.
What is the difference between root canal and cavity filling?
A root canal cleans out the bacteria and any damaged tissue in order to make the area less painful and to help save the tooth. A cavity filling brings back the functionality and appearance of the tooth.
Basically, a root canal is like a filling but for the inside of the tooth, deep in the roots, where the nerve and blood supply is. A “regular” filling is to address decay on the top part of the tooth.
Cavities are no fun, but it’s important to know what your options are, how much a filling could cost, and how to go about getting and caring for a filling.
After all, there’s no point in making a not-fun cavity even more not fun.
