If you’re struggling with decayed or somewhat damaged teeth, then dental fillings may be the ideal solution for you. Not only will they renew your beautiful pearly whites, but they’ll also help protect them from bacteria and further harm. However, you may be wondering how long your results will last. Keep reading to learn about the usual lifespan of dental fillings, when they need to be replaced, and how you can make the most of them.

How Long Do Dental Fillings Typically Last?

The longevity of this restorative treatment will often depend on the patient’s lifestyle choices. Typically, you may expect dental fillings to last around 10 years. That said, the kind of material used to construct them and the overall health of the tooth can significantly impact their lifespan. By keeping a well-balanced diet, practicing good oral hygiene, and refraining from poor oral habits, fillings can potentially last up to 20 years.

How to Know If I Need to Replace My Filling

While these restorations can be used as a long-term solution, it’s important to remember that they won’t last forever. For this reason, you’ll want to keep watch for any indications that you may require a replacement for your filling. Several signs to look out for include:

  • You’re experiencing tooth discomfort
  • You feel increased tooth sensitivity
  • Your filling is chipped, cracked, or otherwise damaged
  • You sustained an injury to the tooth
  • Your filling is noticeably discolored
  • Your filling is old

How Can I Extend the Lifespan of My Dental Filling?

If you wish to prolong the lifetime of your dental filling, there are certain measures you’ll need to take to make the most of them. Here are some essential tips to help you preserve your restorations for as long as possible:

  • Brush your teeth twice daily with fluoridated toothpaste and a soft-bristled toothbrush.
  • Floss your teeth before going to bed and/or after every meal.
  • Avoid hard, crunchy, and sticky foods that can damage your fillings.
  • Refrain from overindulging in sugary and starchy foods, which can contribute to decay.
  • Consume dark-pigmented meals and drinks in moderation, as they can stain your teeth.
  • Ask your dentist about nightguards for bruxism if you clench or grind your teeth at night.
  • Schedule routine checkups and cleanings every six months.

Although dental fillings aren’t a permanent solution, they’re effective at keeping your teeth safe and healthy in the long term. Keep these few tips in mind, and you can be sure to enjoy the benefits of your renewed smile for many years to come!

I've been coming to this practice for years now since moving to the Raleigh area. The office is always clean and organized and the staff have always been friendly and communicative. Also, the TV's mounted to the ceiling are a nice touch! I've been seeing Dr. Laster for several years before our insurance changed causing me to change to Dr. Rensch. Both are so easy to talk to and always made me feel at ease.

From beginning to end 5/5! I thought I was experiencing a dental 911. I submitted an inquiry at 11:30pm and by 8am the next morning, Deidra (front office staff) was already leaving me a message. She was so sweet and patient at 8am lol. After our initial conversation, I informed all follow up dentists “I found my dentist office” but thank you so much! Today I was welcomed with the same energy from Diedre to Britany then finally Dr.Wrench. The music playing throughout the office was fantastic; ie music selection and volume. The TV’s on the ceiling and wall made my procedure so painless and enjoyable! I watched an entire Christmas movie lol! Dr. Wrench (apologies for spelling) made my teeth absolutely perfect! I left telling my friends and family I have a million dollar smile! 😊 I can tell he wanted them perfect and he did! Thank you all so much for being amazing! Sincerely, Your next patient.

Dr. Laster and Dr. Rensch go above and beyond for their patients. I have seen both for various treatments and I always feel comfortable and heard. They take time to listen and to talk with you. They explain your options and work with you to develop the best plan for your care. They are always upbeat and positive and you can tell they truly love what they do. The front desk staff is exceptional as well. Deidre is so caring and very sweet. She’s efficient, understanding and conscientious of your time. I highly recommend.

Connections Dentistry was great! The staff is so friendly and truly cares about their patients. My appointment was quick, and honestly the best dental experience I’ve had. They are great about offering helpful solutions without making you feel like you are being reprimanded… which was the reason I was putting off the dentist. 100% recommend!
