Dental Crown Replacement: When and How to Get It Done

Dental crowns play a crucial role in protecting and restoring damaged teeth. Over time, however, these crowns can wear down, crack, or become loose, requiring a replacement. A dental crown replacement ensures continued protection for your tooth while maintaining its function and aesthetics. In this article, we will discuss when patients should consider replacing their crowns and what to expect during the procedure.

When Should You Replace a Dental Crown?

Dental crowns are designed to last for many years, but several factors can affect their longevity.

Cracked, Chipped, or Worn-Out Crowns

Dental crowns endure chewing forces, teeth grinding, and exposure to varying temperatures. Over time, small cracks or chips may develop, reducing their durability. Minor cracks may be repairable, but if the damage is severe, dental crown replacement is necessary. Habitual teeth grinding can also accelerate wear, shortening the crown’s lifespan.

Loose or Detached Crowns

The cement that holds a crown in place can weaken over time, causing the crown to loosen or fall off. A loose crown allows bacteria to enter, increasing the risk of decay underneath. If a crown is unstable or completely detached, a visit to the dentist is required for proper reattachment or replacement.

Discolored or Unattractive Crowns

Dental crowns are designed to blend seamlessly with natural teeth, but discoloration may occur over time. This is especially true for porcelain-fused-to-metal (PFM) crowns, where gum recession can expose the metal underneath. If a crown no longer matches the surrounding teeth, replacing it can restore a more natural and aesthetically pleasing smile.

Decay or Damage Beneath the Crown

Although crowns cover and protect the natural tooth, decay can still develop underneath, particularly if the crown does not fit properly or if oral hygiene is inadequate. If a dentist detects decay or infection beneath a crown, it must be replaced to prevent further complications.

The Dental Crown Replacement Procedure

Examination and Evaluation

The dentist will examine your existing crown and the underlying tooth. This may include taking X-rays to detect signs of decay, infection, or structural damage. If the supporting tooth is damaged, additional treatment, such as a root canal, may be required before placing the new crown.

Removal of the Old Crown

Before replacing the crown, the dentist will use specialized tools to remove the old crown without damaging the tooth underneath. If decay or damage is discovered, the dentist will treat it before proceeding to the next steps.

Preparing the Tooth

Once the old crown is removed, the dentist will fill and reshape the tooth to ensure it fits properly with the new crown. This may involve removing a small layer of enamel to create a stable foundation. If the tooth is severely damaged, filling or building up a core may be necessary to support the new crown.

Taking Impressions for the New Crown

After preparing the tooth, the dentist will take an impression of the tooth using traditional molds or digital scanning technology. This impression will be sent to the dental lab to craft a new crown that matches the color, shape, and size of your natural teeth.

Placing a Temporary Crown (if needed)

While the permanent crown is being made, the dentist may place a temporary crown to protect the prepared tooth. Temporary crowns, usually made from acrylic resin, are a short-term solution until the permanent crown is ready.

Fitting and Securing the New Crown

Once the permanent crown is ready, you will return to the dentist to have it placed. The dentist will check the fit and bite, make adjustments if needed, and secure the crown with dental cement. Finally, the crown will be polished to ensure a smooth, natural-looking surface.

How Long Can a New Crown Last?

The lifespan of a dental crown depends on several factors, including the material, oral hygiene habits, and daily wear and tear. On average, a well-maintained crown can last anywhere from 10 to 15 years, or even longer. To ensure a long-lasting crown, maintain good oral hygiene, avoid chewing on hard objects, and visit your dentist regularly for check-ups.

How to Care for a New Dental Crown

Proper care is essential to extend the life of your crown. Here are some important tips:

Maintain good oral hygiene: Brush your teeth twice a day and floss to prevent plaque buildup around the crown.

Avoid hard and sticky foods: Do not chew ice, hard candy, or sticky foods that could damage the crown.

Wear a night guard if necessary: If you grind your teeth at night, use a night guard to reduce wear on the crown.

Visit the dentist regularly: Regular check-ups can detect and address any issues with your crown early.
