It does not give separate numbers for molars and front teeth. Material, bite force, grinding, and home care matter more than tooth position alone. Your dentist can talk with you about your crown. RestorativePublished October 26, 20264 min read ## How long do dental crowns last? Cleveland Clinic says the average lifespan of a dental crown is five to 15 years with proper care. The same page notes that crowns can last upwards of 30 years in some cases, but a crack or other damage can mean replacement sooner. Treat the range as an average, not a promise. A [dental crown](https://towncenterdental.multisites.ai/services/dental-crown) is a tooth-shaped cap that fits over a damaged tooth. Dentists use crowns to protect weak or cracked teeth, cover a tooth after a root canal, and hold a bridge in place. What a crown is made of, how you bite, and how you clean it all play a part in how long it stays in good shape. ## Do crowns last longer on molars or front teeth? We did not find a source that gives a different number for molars and front teeth. The Cleveland Clinic page gives one range for all crowns. So we will not invent one. What we can say is that the two ends of your mouth do different jobs. Back teeth, called [molars](https://towncenterdental.multisites.ai/glossary/molar), do most of the chewing and take the most force. Front teeth bite and show when you smile. Dentists often pick different crown materials for each job, and the material is one of the things that shapes how a crown wears. Crown type What Cleveland Clinic says Where it often fits Metal Rarely chips or breaks, wears well, needs only a small amount of enamel removal, and withstands biting and chewing forces Out-of-sight molars, because of the metal color Porcelain fused to metal Combines the strength of metal with a natural look, lasts almost as long as metal, and the porcelain may chip over time Front and back teeth Pressed ceramic Has a hard ceramic core and mimics natural enamel, and the layers may chip over time Front and back teeth All-ceramic or zirconia Mimics the look of natural enamel, suits people with metal allergies, and zirconia is extremely durable Front and back teeth, depending on the material Resin Fragile and more likely to break than porcelain fused to metal Often used as temporary crowns, which last three to five years on average Cleveland Clinic also says that porcelain-fused-to-metal crowns can slowly wear down the enamel of the teeth that touch them. Zirconia is gentler on the opposing teeth. Ask your dentist which choice fits your mouth. Learn the terms in our glossary: [porcelain-fused-to-metal crown](https://towncenterdental.multisites.ai/glossary/porcelain-fused-to-metal-pfm-crown) and [zirconia](https://towncenterdental.multisites.ai/glossary/zirconia). ## What shortens the life of a crown? Several things can cut a crown’s life short. - **Grinding or clenching.** Extra force can crack a crown or the tooth under it. Cleveland Clinic suggests asking your dentist about a custom mouth guard if you grind, a habit called [bruxism](https://towncenterdental.multisites.ai/glossary/bruxism-teeth-grinding). - **Hard or sticky food.** Ice, hard nuts, popcorn with kernels, and sticky candy such as taffy can damage or dislodge a crown. - **A poor fit.** A crown that does not fit properly can trap bacteria and lead to decay. - **Skipped cleaning.** Plaque that builds up along the crown edge can cause trouble. Only your dentist can remove tartar, but daily flossing helps keep plaque from building up, as MouthHealthy explains. - **Chips and cracks.** Porcelain layers can chip over time, which may expose the metal beneath. ## How do you care for a crown? Cleveland Clinic recommends these steps: 1. Brush twice a day with fluoride toothpaste and a soft-bristled toothbrush. 2. Floss once a day. 3. Use an antibacterial mouthwash to keep plaque and bacteria down. 4. Avoid extremely hard, crunchy, or chewy foods. 5. Ask about a custom mouth guard if you grind or clench your teeth. 6. Keep your regular dental cleanings and exams. Regular exams give your dentist a chance to look at the crown edge and the bite before a small problem grows.

A short list of questions can help you plan. - Which material do you suggest for this tooth, and why? - Will this crown touch or rub against the teeth that bite on it? - Do I grind or clench? Should I wear a guard? - What signs should make me call you? - How often should you check this crown? Good answers give you a clear picture of what to watch for. They also help you keep the crown in good shape for as long as you can. ## When should you call your dentist about a crown? Call your dentist if you notice any of these, per Cleveland Clinic: - A loose crown - Bad breath or a bad taste - Cracks or chips in the crown - Sharp edges that bother your tongue or gums If a crown comes off, keep it and call the office. Our post on a [lost filling or loose crown](https://towncenterdental.multisites.ai/blog/lost-filling-or-loose-crown-what-to-do-until-you-are-seen) explains what to do until you are seen. If you are wondering what a new crown may feel like, read [do dental crowns hurt](https://towncenterdental.multisites.ai/blog/do-dental-crowns-hurt-during-and-after). When a crown wears out, the answer is usually a new crown, not a repair. Your dentist will talk with you about the tooth under the crown and the next step. Cleveland Clinic says that if you notice wear, tear, or damage, it is time to think about replacement. ## Next step Learn more about [dental crowns at Town Center Dental](https://towncenterdental.multisites.ai/services/dental-crown), then call (636) 273-5866 or [request an appointment](https://towncenterdental.multisites.ai/request-appointment) if you want a dentist to look at a crown you already have. ## Frequently asked questions ### Do crowns last longer on front teeth or back teeth? The Cleveland Clinic page we reviewed gives one average range, five to 15 years, and no split by tooth. Back teeth handle more chewing force, so dentists often choose strong materials for them. Your dentist can talk with you about the likely wear on your own tooth. ### What are signs a crown needs to be replaced? Cleveland Clinic says to call your dentist about a loose crown, cracks or chips, sharp edges, or a bad taste or bad breath. It also says that wear, tear, or damage means it is time to think about replacement. Only an exam can confirm what is wrong. ### Does grinding my teeth shorten the life of a crown? Cleveland Clinic says that if you grind or clench your teeth, you should ask your dentist about a custom mouth guard. Grinding adds force to every tooth, including a crowned one. Your dentist can check for signs of wear and talk about a night guard. ### Can a crown last longer than 15 years? Cleveland Clinic says crowns can last upwards of 30 years with proper care, though it also says a cracked or damaged crown may need replacement sooner. Treat 5 to 15 years as the average, not a promise. Care at home and regular checkups both matter. ## Terms on this page - [Porcelain-fused-to-metal (PFM) crown](https://towncenterdental.multisites.ai/glossary/porcelain-fused-to-metal-pfm-crown) - [Bruxism (teeth grinding)](https://towncenterdental.multisites.ai/glossary/bruxism-teeth-grinding) - [Mouthwash (mouth rinse)](https://towncenterdental.multisites.ai/glossary/mouthwash-mouth-rinse) - [Bad breath (halitosis)](https://towncenterdental.multisites.ai/glossary/bad-breath-halitosis) - [Fluoride toothpaste](https://towncenterdental.multisites.ai/glossary/fluoride-toothpaste) - [Tartar (calculus)](https://towncenterdental.multisites.ai/glossary/tartar-calculus) - [Gums (gingiva)](https://towncenterdental.multisites.ai/glossary/gums-gingiva) - [Dental crown](https://towncenterdental.multisites.ai/glossary/dental-crown) - [Lost filling](https://towncenterdental.multisites.ai/glossary/lost-filling) - [Mouth guard](https://towncenterdental.multisites.ai/glossary/mouth-guard) ## Sources 1.
