Full coverage crowns are meant to protect a tooth for many years, but they do not last forever. Like any dental restoration, full coverage crowns go through daily wear from chewing, biting, brushing, and changes in the mouth over time. If your dentist has recommended a crown, or if you already have one, you may be wondering when it will need to be replaced. Read on to learn more about how long full coverage crowns last and what can affect their lifespan.
How long do full coverage crowns last?
Most full coverage crowns last between 5 and 15 years. Some last longer with good care. In some cases, a crown can last 20 years or more, especially if it is made from a strong material and the person has good oral hygiene. There is no exact timeline for every crown. There are numerous factors that impact the lifespan of a crown.
- The material used plays a big role. Porcelain and ceramic crowns are often used for front teeth because they look more natural. These crowns can last for many years, but they may be more likely to chip than metal crowns. Metal crowns, such as gold or other alloys, are very strong and are often used on back teeth. These teeth handle more pressure from chewing, so strength matters in that area.
- The location of the crown matters a lot, too. A crown on a back tooth usually works harder than a crown on a front tooth. Molars are used for chewing and grinding food, which means they take on more force. A crown in that part of the mouth may wear down sooner than one placed on a tooth that does less heavy work.
- The condition of the tooth under the crown can affect the lifespan. The crown covers the tooth, but it does not make the tooth immune to problems. Decay can still form near the edge of the crown where the natural tooth is exposed. If that happens, the crown may loosen or need to be replaced.
- Daily habits can influence how long a crown lasts. Chewing ice, biting fingernails, using teeth to open packages, or biting down on hard objects can chip or crack the crown. Sticky foods can also pull at the crown and may loosen it over time.
- Teeth grinding is another common problem that shortens the crown’s lifespan. Many people clench or grind their teeth at night without knowing it. This puts extra pressure on crowns and natural teeth. If your dentist sees signs of grinding, they may recommend a nightguard to protect your mouth while you sleep.
How can I help my crown last?
The best way to help a crown last is to keep the tooth and gums around it healthy. Brushing twice a day, flossing daily, and keeping up with regular dental visits are important. It is also smart to avoid chewing on hard objects. If your bite feels uneven after a crown is placed, tell your dentist. A crown that does not fit your bite correctly can receive too much pressure and wear down faster.
When should a crown be replaced?
A crown needs to be replaced if it becomes loose, cracked, painful, or sensitive. You may also notice swelling near the gums, a change in your bite, or a dark line near the crown’s edge. Sometimes a crown looks fine but has a problem underneath it, which is why regular dental exams are important. If you think your crown has been compromised, speak with your dentist right away.
