A porcelain crown is more like a natural tooth but with a hollow space within it like a dental cap and must be worn over the affected tooth. It entirely covers the portion of the affected tooth and can last for many years if properly cared for.

On average, porcelain crowns can last between 5 to 15 years. But the longevity of your full porcelain crown is determined by your personal lifestyles and mouth-related habits, the oral hygiene practices you followed, and the amount of wear and tear the dental crown can take.

Normally, daily wear will cause the permanent porcelain crowns to weaken and wear off, but certain lifestyles can accelerate the process. To make your dental crown last longer, you must avoid unhealthy lifestyles, such as teeth clenching or grinding, using your teeth as a tool or to open packaging, biting fingernails, and chewing on hard objects such as ice, pen caps or nut, etc. These unhealthy lifestyles only exert excessive pressure on the full porcelain crowns causing its lifespan to be shortened.

When you take proper care of your permanent porcelain crowns, you can make them last as long as 25 to 30 years or beyond. Please take note that underlying tooth must also be kept healthy and strong. Otherwise, the underlying tooth may sustain recurrent decay and your dentist may have to remove the dental crown to perform some forms of treatment if necessary.

The following tips will help you to extend the lifespan of your full porcelain crown:

  • Avoid biting your fingernails, chewing on hard objects like hard candy or ice. Doing this would not only cause damages to your porcelain crowns but also to your natural teeth.
  • Always observe good and proper dental hygiene practices, such as brushing your teeth thrice daily and flossing twice daily. When you brush, pay careful attention to the areas around the dental crowns, especially the gumline. This will keep food chunks and plaques, which may cause dental decay, away from under the dental crown.
  • Avoid grinding or clenching your teeth. Doing this will cause your full porcelain crowns to crack or chip. If you naturally suffer from bruxism (unconscious grinding or clenching of the teeth), it is recommended that you make use of a bespoke mouth guard. Doing this will help with protecting your full porcelain crowns and also your natural teeth.
  • Schedule a regular visit to your dentist for dental checkup and cleaning appointments. During these visits, your full permanent porcelain crowns would be examined by your dentist for any signs of a dental cavity, gapping between the dental crown and natural teeth, trauma, or decay.

How Do I Know When My Full Porcelain Crowns Need Replacing?

Like stated above, porcelain crown wears in the long run due to daily and the amount of wear is peculiar to each person. Although a porcelain crown is durable, it is not indestructible i.e. it can be damaged or destroyed over time. Hence, full porcelain crowns need to be replaced if they crack or chip.

Leaving a damaged, cracked, or chipped porcelain crown in your mouth can increase the possibilities of having dental caries under the porcelain crown. Although porcelain crowns cannot get decayed, dental cavities can form under them if good and proper oral hygiene practices are not followed. So, depending on the extent of the dental decay and the condition of the porcelain crown, a porcelain crown replacement may be necessary. If the dental decay is not properly and immediately taken care of, the underlying tooth may become severely damaged and require a root canal treatment.

A poorly fitted crown, misfit crown, and imbalanced bite are common causes of porcelain crown failure and can also be reasons why permanent porcelain crowns would fail earlier than expected. Luckily, the cost of replacing a failed porcelain crown is covered by most insurance companies as long as the porcelain crown is fitted more than five years old.

More so, accident or hard impact can cause the full porcelain crowns to fracture or chip.

Other Causes of Porcelain Crown Failure

Poor Oral Hygiene

Like stated above, full porcelain crowns are not vulnerable to decay, but the underlying teeth are. If debris and bacteria are trapped underneath the porcelain crown, a dental cavity can develop. In such a case, the porcelain crown would be removed so as to access and treat the underlying tooth.

Poorly Manufactured Crowns

A subpar manufactured porcelain crown is more likely to fail later on. This is why it is very important to have your porcelain crown procedure handled by a reputable and professional dentist. The best dentist for dental crown would ensure that your full porcelain crowns fit perfectly in your smile. Unlike a dental bridge, a dental crown is not designed to handle the impact of your bite. So, if your bite brunt is not distributed evenly across your teeth, your porcelain crown may become damaged.

Aesthetics

A dental crown made from porcelain-fused-to-metal material always has a metal base. And after a while, the metal base will start to show through, giving the tooth a dark shade. This is more reason why some patients prefer to replace their metal dental restorations with restorations made of zirconia or porcelain for more appealingly results.

Take Home

One of the simplest and easiest ways to make your permanent porcelain crowns last longer is to observe good oral hygiene practices. Brush your teeth at least thrice daily and floss at least twice daily. When brushing, give careful attention to the base of the porcelain crowns where the dental crown meets the gumline. Refrain from clenching or grinding your teeth and if you suffer from bruxism, quickly consult your dentist, refrain from biting on ice, hard candy or other hard objects and tell your dentist if you suffer from bruxism. More so, it is important to schedule an appointment to your dentist at least twice a year for dental cleanings and checkup. During such dental visit, your dentist would examine your dental health, the state of your dental crown as well as that of the underlying tooth. If the dentist discovers any sign of dental decay, he or she would have to recommend an additional treatment.
