There is no single number of how many times you can have a filling replaced. Usually, we will stop replacing the dental filling after the hole becomes too large. Once you have more filling material than natural tooth material your tooth no longer holds enough strength.
It is okay to choose to replace fillings at any time, however, there are some considerations. Any time a filling is replaced more tooth structure is removed weakening the tooth.
You'll need to have the filling replaced to prevent new decay. If you have a composite filling, it's normal for it to discolor over time. As a result, it can stick out like a sore thumb. You can have it replaced to ensure it continues to blend in seamlessly when you smile.
We can try replacing the filling if the tooth will allow it, or we will need to do additional treatments. For deep fillings that sit upon the root of a tooth, you will probably need a root canal. A root canal is used when the nerve becomes inflamed or infected.
Typically, fillings last around 10 years. Many restorations (the clinical term for dental fillings) last much longer. In addition to the materials used, other factors affecting the life span of a filling include: your eating habits.
The scientific literature shows that most white composite fillings will last about 7-10 years in healthy patients – but this estimate is based on older kinds of composite fillings, and significant advancements in filling manufacturing have been made since that time (and continue to be made).
The dentist can remove an amalgam filling using an evacuator. This piece of equipment is a powerful suction system that can remove mercury vapors and amalgam particles. An evacuator must always be turned on during the removal of an amalgam dental filling.
If the seal between the filling and tooth enamel breaks down, decay-causing bacteria and food particles can get under the filling. These bacteria are hard to remove easily with a toothbrush. A person will then be at risk of developing additional decay in the tooth.
Although some of the materials are strong and durable, none are considered permanent. This means that fillings do not last forever. One of the main factors that determine how long a filling lasts is the material used to fill the tooth. Gold and amalgam often last the longest.
Fillings are not intended to last forever. The bond that holds the metal or composite resin in place will eventually weaken over time. This process may occur more quickly if patients grind their teeth at night. Fillings are often placed in molars where bruxism can cause significant damage.
Overall Health and Old Amalgam Fillings
All silver amalgam fillings contain nearly 50 percent mercury. The element is highly toxic. In fact, there really isn't a safe level when it comes to mercury exposure. The truth of the matter is your old silver amalgam fillings could be making you sick.
While dental filling material has improved over the last few decades, fillings are still softer than the enamel the surrounding tooth is composed of. This means they may not be able to survive the same forces of chewing and biting as the natural enamel.
In general, adults develop an average of three cavities during their lifetimes. This means that the average adult has three or four fillings in their mouth. Some patients end up with ten or more fillings depending on how well they care for their teeth.
Sometimes, the bacteria in your mouth can work their way into the seam between an old dental filling and the tooth enamel. This can cause sensitivity, general discomfort, or increasing toothache pain. Without treatment, this could result in a severe cavity to within the tooth.
Composite fillings are made from a resin designed to match the color of tooth enamel. They aren't as noticeable as metal fillings, but they are less durable. Composite fillings may cost between $150 to $300 for 1–2 teeth or $200 to $550 for 3 or more teeth.
There are many signs that your filling may need to be replaced. Some of these include sensitivity to hot or cold food or beverages, an uneven surface, cracking, chipping, or decay around the filling, a broken tooth again, shifting of a tooth's position, or a change in the color of a tooth after it has been filled.
Should Dental Amalgam Fillings Be Removed? If your filling is in good condition and your dentist or health care professional says there is no decay beneath the filling, removal of your amalgam filling is not recommended.
There are two main risks to getting fillings: infection and damage. Sometimes when you get a filling, it can pull away from the tooth which leaves a small space open. This space is an area where bacteria can get in and cause more tooth decay and infection. Cavity fillings can also break or fall out completely.
On occasion, after the placement of a restoration, a tooth can become non-vital and require root canal treatment. Every time a filling is placed or replaced, there is trauma to the pulp (nerve and blood supply). It can be a combination of many things that will cause this trauma.
Dental Filling Costs
The dental filling cost ranges between $115 and $300 in Australia. If the filling cost is out of your budget, you can check to see if dental fillings cover your private insurance. The dental filling cost has several tangible factors linked to it. Let's look at what they are.
These types of fillings are durable and can withstand chewing and other wear and tear. Patients can expect these fillings to last up to 10 years and even longer with good care.
When Will I have to Replace my Filling? Usually, a filling will last anywhere from 7-20 years, although this depends on the location of the filling, the size, and your dental hygiene. Fillings put up with a lot of stress! Every time you chew, your filling is compromised.
Decay will show up on an x-ray as a dark area below a filling or on the side of a tooth. Broken pieces of filling can become wedged between two teeth making flossing difficult or impossible and below this you will see areas of bone loss.
If your tooth has decay to the enamel or dentin, a simple filling is enough to repair the cavity. However, if the cavity is left untreated, the decay will reach the deepest layer of the tooth, the nerve tissue. At this point, a root canal is necessary to repair the tooth.
