Will Your Dental Filling Last a Long Time?

Dental fillings are a great choice when it comes to correcting minor chips and cavities. They are an effective solution that gives you back the function and appearance of your tooth. That said, this modern restoration is often made from natural-looking materials, like composite resin. It’s different from its metal counterpart, so you might wonder how long your results will last. Here’s what to know.

Do Dental Fillings Last a Long Time?

Amalgam, or silver, fillings used to be the only option for this treatment. They are known for their sturdiness and lifespan, but these more aesthetic versions can last for quite a while. In short, they can stay strong for up to seven years or longer; it just depends on your diet and oral hygiene routine.

When Do Fillings Need to Be Replaced?

While tooth-colored fillings can last, they will eventually need to be replaced if they’ve taken noticeable damage, fallen out, or are getting too old. In many cases, it will let you know when it needs to be swapped out for a new one by:

  • Developing sensitivity as the inner structures are exposed.
  • Causing discomfort when eating, or you might feel it shift when chewing.
  • Food getting stuck in your tooth as there’s a new opening.

How Can I Expand My Fillings Lifespan?

A benefit of composite resin fillings is that they don’t require as much of your tooth to be removed. They can form a stronger bond to last for a long while. That said, you may need a replacement sooner if you aren’t careful. Thankfully, keeping it in great shape is an easy feat.

A simple thing you can do at home is keep up with brushing and flossing. Your oral hygiene will remove plaque that can lead to decay and affect your restoration. Be sure to stick to it twice daily to avoid any problems.

If you tend to grind or clench your teeth, then consider getting a mouthguard. That way, you protect it from pressure that can damage it. Avoid hard, sticky, acidic, and sugary foods as they can all be trouble over time. If you do have them, then rinse with water to wash away any debris left behind.

In the end, don’t forget to visit your dentist. By having routine checkups and cleanings, they can monitor your filling’s condition and ensure it stays strong. If anything is worrying, it can get sorted out before it becomes a big headache. That way, you continue getting good use out of it.
