When Should Dental Crowns be Replaced

Dental crowns are commonly used to restore the structure and function of damaged or decayed teeth. They provide strength, support, and enhance the appearance of a tooth. However, like any dental restoration, crowns have a lifespan and may need to be replaced at some point. In this article, we will explore the factors that determine when dental crowns should be replaced.

1. Wear and Tear

Over time, dental crowns can become worn down or damaged due to regular use. The constant pressure of biting and chewing, as well as habits like teeth grinding, may cause the crown to chip or crack. If the wear and tear are significant, it can affect the crown's functionality and esthetics.

It's essential to pay attention to any visible signs of wear on your crown, such as rough or jagged edges, discoloration, or loose crown. If you notice these issues, it is advisable to consult your dentist for an evaluation.

The average lifespan of a dental crown is around 10-15 years. However, this can vary depending on several factors.

2. Decay or Cavities

Although dental crowns are designed to protect the underlying tooth, they are not invincible. Decay or cavities can still develop around or underneath the crown if proper oral hygiene is not maintained. If your dentist detects decay below the crown during a routine check-up or through an X-ray, removing the crown and treating the decay will be necessary.

The cost of crown replacement due to decay may range from $500 to $1500, depending on factors such as the location of the tooth and the complexity of the procedure.

3. Gum Recession

Gum recession refers to the condition where the gum tissue surrounding the tooth starts to pull back, exposing the tooth's root. If gum recession occurs around a dental crown, it can compromise the crown's stability and expose the underlying tooth structure to bacteria and decay-causing agents.

If you experience gum recession around your crown, consult your dentist. They may recommend crown replacement to ensure proper coverage of the tooth and protect the exposed root.

4. Aesthetic Concerns

Over time, the color of your natural teeth may change due to aging, staining, or certain habits like smoking or consuming foods and beverages that cause discoloration. If you have a dental crown that no longer matches the shade of your natural teeth, you may consider replacing it for cosmetic purposes.

The cost of replacing a crown for aesthetic concerns can range from $800 to $2500, depending on factors such as the type of crown material and the location of the tooth.

5. Crown Failure

In some cases, dental crowns may fail due to various reasons, such as improper fit, recurrent decay, or damage to the underlying tooth structure. If a crown fails, it may cause pain, discomfort, or difficulty in biting and chewing. Seeking prompt dental care is crucial to prevent further damage or complications.

The cost of crown replacement due to failure may vary depending on the specific case and necessary treatment options. It is best to consult with your dentist to determine the appropriate course of action.

6. Root Canal Treatment

When a tooth requires a root canal procedure, it often results in a weakened tooth structure. In such cases, a dental crown is commonly placed to provide strength and protection to the treated tooth. However, if the crown becomes loose, damaged, or if decay develops, crown replacement may be necessary.

The cost of crown replacement after root canal treatment can range from $1200 to $2500, depending on factors such as the tooth's location and the complexity of the case.

7. Shifting or Misalignment

Teeth can shift over time due to various factors, including genetics, age, trauma, or gum disease. If the alignment of your natural teeth changes, it can affect the fit and functionality of a dental crown. Additionally, misaligned teeth can cause uneven biting forces, leading to potential crown damage.

If you experience shifting or misalignment of your teeth, consult your dentist. They will assess the situation and determine if crown replacement or other orthodontic treatments are necessary.

8. Allergic Reactions or Sensitivity

In rare cases, people may develop allergic reactions or sensitivity to the materials used in dental crowns, such as metal alloys or porcelain. If you experience persistent discomfort, gum irritation, or allergic symptoms like swelling or rash, it is important to consult your dentist promptly.

Your dentist may recommend crown replacement using alternative materials that suit your specific needs and minimize the risk of allergic reactions.

9. Upgrading to Better Materials

Advancements in dental technology continually introduce new and improved materials for dental crowns. If you have an older crown made from less durable or aesthetically pleasing materials, you may consider upgrading to a crown that offers better longevity, strength, or esthetics.

The cost of upgrading a dental crown can vary depending on factors such as the choice of material and the complexity of the procedure. Discuss with your dentist to determine the best option for your specific case.

10. Regular Dental Check-ups

Regular dental check-ups are crucial for maintaining your oral health and detecting any issues with your dental crowns early on. Your dentist will assess the condition of your crowns, check for any signs of wear or damage, and recommend appropriate treatment or replacement if needed.

3. What is the process of replacing a dental crown?

Replacing a dental crown involves numbing the area, removing the existing crown, preparing the tooth, and taking impressions for the new crown. The impressions are then sent to a dental laboratory for fabrication. In the meantime, a temporary crown may be placed. Once the new crown is ready, it is cemented onto the tooth.
