How Dental Crowns Help Protect Teeth After Root Canal Treatment

Many patients think that once their root canal is done, the hard part is over. While that's mostly true, a tooth that has had a root canal is more fragile than it appears. Without a crown, the tooth is at a higher risk of cracking or breaking. A dental crown can give the tooth the strength it needs to function properly for years. 

 At Junée F. Gardy DDS, PA in Naples, FL, Dr. Junée F. Gardy uses a comprehensive approach to restorative dentistry to ensure each treated tooth is protected. Call us today to learn more about root canal recovery and book a consultation. 

Why is a tooth more fragile after a root canal? 

During a root canal, the infected or damaged pulp inside the tooth is removed, and the interior is cleaned and sealed. This saves the tooth from extraction, but it also leaves it hollowed out and significantly more brittle than a healthy tooth. Without that resilience, the remaining structure is prone to fracturing. 

Root canal recovery involves more than just waiting for your tooth to heal. The tooth also needs to be properly reinforced before it can function normally again. A dental crown can achieve this and more. 

What to know about dental crowns 

A dental crown, sometimes called a dental cap, is a custom-made covering that fits over the visible portion of a tooth. It restores the tooth's shape, size, and strength while protecting the structure underneath from further damage. 

In the context of restorative dentistry, a dental cap is one of the most reliable ways to extend the life of a tooth compromised by decay, damage, or root canal treatment. 

Crowns are made from a variety of materials, including porcelain and ceramic, and Dr. Gardy will recommend the right option based on the location of the tooth and your unique needs. 

Getting a crown after root canal treatment 

Getting a crown after root canal treatment typically involves two appointments. During the first visit, Dr. Gardy will shape the tooth to accommodate the crown, take custom impressions, and place a temporary dental cap while the new one is being fabricated. 

At the second appointment, the crown is fitted, adjusted, and cemented into place. The process is straightforward and comfortable, and most patients find that root canal recovery feels much more complete once the crown is in place. At Junée F. Gardy DDS, PA in Naples, FL, each crown is crafted to match the surrounding teeth in color and shape for a seamless, natural-looking result. 

How long do dental crowns last? 

So, how long do dental crowns last? With proper care, most crowns last between 10 – 15 years, and many last much longer. The longevity of a dental cap is based on the material used, where it's located, and how well it's maintained. 

Brushing and flossing regularly, avoiding habits like chewing ice or grinding teeth, and keeping up with routine dental visits all contribute to a longer lifespan.
