Dental crowns are a convenient and highly effective restoration solution when decay compromises natural teeth or a beautiful smile. Although these thin tooth caps are durable and can withstand the same exposure to everyday stresses of chewing and biting as natural teeth, proper care and maintenance can ensure that crowns last as long as possible.

How Durable Are Metal Free Crowns?
Metal free crowns are dental restorations fabricated completely of ceramic. The most appealing feature of metal-free crowns is that they closely resemble natural teeth, making them a popular choice nowadays. Metal free crowns are one of several dental restoration options accessible to patients. Read on to learn more about this type of dental crown.
The need for metal free crowns
Metal free crowns are now widely used in dentistry and are chosen for multiple reasons, not least of which is their biocompatibility. As a result, many people prefer to have this treatment done and receive its additional benefits. Metal free crowns are composed of high-quality materials that are also extremely long-lasting.
Metal free crowns are indicated for those who have a damaged tooth due to trauma, decay, or accidents. The dentist will install the crown to prevent further damage to the tooth and restore its function and structure. Metal free crowns have mechanical qualities similar to standard metal-ceramic crowns, but they also offer other advantages.
There have been several technical improvements in porcelain manufacture and adherence, allowing dentists to preserve more teeth using various metal-free crown choices.
The durability of metal free crowns
When metal restorations are exposed to hot or cold conditions, they expand and contract, potentially putting enough stress on the original tooth beneath to cause it to fracture. Fortunately, metal-free restorations do not have this problem, allowing them to survive far longer than metal-based crowns.
Metal free crowns are constructed of porcelain, which is extremely durable and thus ideal for the teeth. For someone who has experienced tooth decay, the choice of porcelain makes it even better as the material is durable and can protect the tooth from bacteria and other organisms that cause tooth decay. While metal free crowns that are well taken care of can last up to 25 years, there are a number of variables that might affect their longevity. These factors include:
- Dental hygiene: Patients can prevent cavities and gum disease by brushing and flossing regularly. Even though the all-ceramic crown is not susceptible to decay, it can still accumulate plaque and germs, affecting the remaining teeth and gums
- Oral habits: All-ceramic crowns are durable and can resist daily wear and tear at the front of the mouth. However, the crowns might crack or shatter if patients indulge in discouraged habits like nail-biting, ice chewing, and opening packages with the teeth
- Bruxism: Excessive pressure is placed on the teeth when patients grind and clench their teeth, a condition known as bruxism. This can wear down and harm the ceramic crowns as well as the natural teeth. Patients who grind their teeth can get a custom-fit sleep guard to protect their crowns and teeth during the night
With proper care, metal free crowns can be quite durable, making them a good investment in your oral health.
