Amalgam fillings are durable and effective, which is why they have been used for well over years. On average, you can expect a metal filling to last for about 15 years before needing to be replaced, but the length of time can vary based on several factors, such as if you grind or clench your teeth. Tooth-colored fillings are made from a mixture of fine glass and plastic particles.
They are customized to match your enamel to blend in when you smile. They generally last 10 to 12 years before needing to be replaced. There are several reasons why your filling may need to be replaced over time.
Most often, it is the result of daily wear and tear. As you chew, your filling is placed under a great deal of pressure. A study found that the average age of an amalgam filling at the time it needed to be replaced was about 15 years, give or take 6 years on average. Research from put the survival rate of amalgam fillings provided by private dental practices between 7.
With mercury amalgam fillings, there may be a risk of toxicity. You should not have a mercury amalgam filling if you:. Composite fillings are popular with patients because the color can often be matched to the color of the surrounding teeth.
Composite fillings chemically bond with the surrounding tooth with an adhesive. But they last on average about 7 years, according to a study. Research from has shown that they can last 10 years or more if fillings are smaller and patients have good oral health. The materials used for composite fillings are also used to repair chipped teeth and fill in small gaps between teeth. As you might imagine, gold fillings are much more expensive than amalgam or composite restorations.
Ceramic fillings need to be made by a dental lab or milling machine and glued into the tooth. Glass ionomer fillings are made with a kind of glass and acrylic and can be placed directly in the tooth.
They typically last about 5 years. And sometimes, a filling just falls out and needs to be replaced. You may not notice when a filling first has problems, but your dentist should be able to spot trouble early on during a routine checkup. Dental X-rays can also reveal decay under the filling or anywhere nearby. Eating sugary foods is one of the biggest predictors of how long your fillings will last. Sugar can make it easier for biofilms to grow on your fillings and cause new cavities underneath existing fillings as well as on previously healthy teeth.
Biting down on hard candy, nuts, ice , and other hard foods can increase the wear and tear on your fillings and your teeth.

But if the tooth has already experienced considerable decay, a traditional filling may be necessary. This makes it two times more resistant to fracture than standard composite fillings. Silver fillings can last for 10 years with proper dental care, and they are very affordable. Dentists have been using amalgam fillings for many years now, especially on the back teeth where they are not noticeable.
Like the gold dental fillings , silver fillings stand out in the mouth. And, some patients with silver fillings have experienced sensitivity to cold and hot due to amalgam fillings. They can also discolor the surrounding tooth or cause cracks and fractures. But, silver fillings are the best options for kids in back molars. They stay put and last a long time. And they are the most affordable on this list. The dental fillings that have the shortest shelf life are composite or tooth colored fillings.
They can last up to ten years with good dental hygiene. But the appeal with composite dental fillings is that they match the color of the tooth. So, an advantage of having composite fillings is that they chemically bond to the remaining tooth structure, which gives the tooth way more support.
And, dentists can use the same material to fill in chips and cracks in the teeth. A dental filling can last anywhere from 10 to 20 years with proper care. That means regular dentist check ups and brushing and flossing the teeth twice daily. This will increase the longevity of the fillings.
