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.
There is no predetermined number of times you can replace dental fillings. Generally, dentists refuse to replace dental fillings if the cavity expands to become too large. Your tooth loses integrity every time you must have the tooth-filling material replaced.
Permanent tooth fillings can last around 5-20 years or a lifetime. Their durability is affected by eating habits, tooth-grinding or jaw-clenching, and oral hygiene. Dental trauma to the filled tooth or decay around the filling can reduce the longevity of fillings.
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.
The number of fillings you can get will depend on a few factors, including the size and location of the tooth, the filling material used, and the dentist's skills. However, most teeth can safely have up to three fillings.
So, if you have one dental filling, maybe it's OK. But if you have more than eight dental filings, the potential risk for adverse effect is higher," Yu said. People with numerous dental fillings who are also exposed to mercury from other sources, such as seafood or work environments, are most at risk.
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.
Once you have more filling material than natural tooth material your tooth no longer holds enough strength. In this instance, you might need an inlay, onlay, or dental crown to protect your tooth. You might also need a restoration instead of filling replacement if your tooth has several fillings in the same tooth.

Cavities are one of the most common health problems. Over 90% of adults in the US have had at least one cavity in their mouth. On average, adult patients have had around 3-4 cavities in their lifetime.
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. Over time, it can cause it to crack, leak, or fall out.
While fillings are considered a permanent solution to cavities, they will eventually wear out, come loose, or develop other problems. Most adults will need to have one or more of them replaced during their lifetime. There is no set timeline for when dental fillings need to be replaced.
The average American adult has three fillings. But if you tend to get a lot of cavities, you may be wondering why. Are you more cavity-prone than other people?
So, what can you expect from a filling replacement procedure? Well, it's mostly the same as a regular filling procedure, but with a tad more work on the part of the dentist, who will remove the old or damaged filling and replace it with a new one. As with any filling, you always have options.
Ignoring it will do more harm than good inside the mouth. In fact, according to research published in the Journal of Dentistry, a bad or worn out dental filling can increase tooth decay, infection, and mean more fillings will be needed, particularly on neighboring teeth.
If left untreated, it could eventually become a cavity. Even if a person has small cavities, they need to be filled as soon as possible. But if decay is caught early enough, there are several options available that can help a person avoid a filling.
Recurrent Decay – Cavities Under Fillings
This can happen when fillings and crowns are not properly installed, causing them to leak. Any kind of dental restoration can still leave some of the decay behind, which will spread to the rest of the tooth if not properly sealed.
Here are several factors that may contribute to a high cavity rate: Diet – “Sip all day, get decay.” If you sip, graze or snack on anything sugary throughout the day, your chances of getting cavities increase by quite a bit.

The frequency of cavity fillings for children is typically one to four, which is the typical number for children. Teenagers' dental hygiene practices can vary, and some may develop more cavities due to their dietary habits, poor oral hygiene, or orthodontic treatments.
Technically, there is no limit to the number of filling you can get in one session. However, dentists do not recommend having more than three fillings at a time.

Insufficient oral hygiene. The quickest way to welcome cavities is to slack on dental care. Not brushing or flossing regularly, and not using mouthwash or brushing your tongue will leave your teeth vulnerable to decay. Brushing your teeth for less than two minutes each time can also lead to cavities.
The reasons can be many, like the spaces between teeth that easily trap food, consuming too much cavity-causing foods and beverages, avoiding regular professional-level cleanings and checkups, etc.
