Tooth crowns, also known as dental crowns, are a type of dental restoration that covers the entire visible portion of a tooth. They are typically made of materials like porcelain, ceramic, or metal, and are designed to restore the shape, size, strength, and appearance of a damaged or weakened tooth. They can be used to protect a tooth that has been severely damaged by decay, injury, or other factors, or to improve the aesthetics of a discoloured or misshapen tooth.
They are a common dental treatment, and they can be an effective way to restore the function and appearance of your teeth. However, like any dental restoration, they may need to be replaced over time. Understanding the factors that can affect their lifespan can help you make informed decisions about your oral health.
Reasons for replacing dental crowns
There are several reasons why you may need to replace them, including:
- Wear and tear: Over time, the materials used to make them can wear down or become damaged, reducing their effectiveness and appearance.
- Decay or damage: If the tooth underneath them becomes decayed or damaged, they may need to be replaced to protect the tooth and prevent further complications.
- Poor fit: If a crown is not properly fitted or becomes loose over time, it may need to be replaced to ensure a secure and comfortable fit.
- Aesthetic concerns: If their colour or appearance no longer matches the rest of your teeth, you may choose to have them replaced for cosmetic reasons.
How many times can tooth crowns be replaced?
There is no definitive answer to how many times they can be replaced, as it depends on a variety of factors. Generally, well-maintained ones can last 10 to 15 years or more before they need to be replaced. However, in some cases, they may need to be replaced more frequently, such as every 5 to 7 years.
It’s important to note that each time a crown is replaced, a small amount of the underlying tooth structure is removed to accommodate it. This means that the more times a crown is replaced, the less natural tooth structure remains. In some cases, if a tooth has been heavily restored, it may not be able to support a new one, and an alternative treatment, such as a dental implant, may be necessary.
Factors to consider when replacing dental crowns
When it comes to replacing, there are several factors to consider, including:
- Material type: The type of material used to make your crown can affect its lifespan. For example, porcelain ones may be more prone to chipping or wear over time, while metal or ceramic ones may be more durable.
- Oral hygiene: Your daily oral hygiene routine, including brushing, flossing, and regular dental cleanings, can help extend their life.
- Grinding or clenching: If you grind or clench your teeth, this can put additional stress on them and cause them to wear down more quickly.
- Underlying tooth health: The health of the tooth underneath the crown can also affect its lifespan. If the tooth becomes decayed or damaged, it may need to be replaced.
- Fit and placement: The way the crown is fitted and placed on the tooth can also impact its longevity. Poorly fitted or improperly placed ones are more likely to become loose or need replacement.
The procedure for replacement
It typically involves the following steps:
- Removal of the old crown: Your dentist will carefully remove the old crown, taking care to preserve as much of the underlying tooth structure as possible.
- Preparation of the tooth: The dentist will then prepare the tooth by removing any decay or damaged tissue and reshaping the tooth to accommodate the new crown.
- Impression and fabrication: An impression of the prepared tooth will be taken, and a new crown will be fabricated based on this impression.
- Placement of the new crown: Once the new crown is ready, your dentist will cement it in place, ensuring a secure and comfortable fit.
The entire process can take two or more dental visits, depending on the complexity of the case and the materials used.
Benefits of replacement
- Improved appearance: A new crown can restore the natural look and feel of your tooth, improving the overall aesthetics of your smile.
- Increased functionality: A properly fitted one can help restore the full function and chewing ability of the tooth, making it easier to eat and speak.
- Enhanced protection: A new crown can help protect the underlying tooth from further damage or decay, preserving the overall health of your oral cavity.
- Increased comfort: A well-fitted one can provide a more comfortable and natural-feeling tooth, reducing any discomfort or sensitivity you may have experienced with the old crown.
How to Take care
To ensure the longevity of your dental crowns, it’s important to follow these tips:
- Practice good oral hygiene: Brush and floss your teeth regularly, and visit your dentist for routine cleanings and checkups.
- Avoid hard or sticky foods: Certain foods, such as hard candies, nuts, or taffy, can put extra stress on them and cause them to chip or crack.
- Wear a nightguard: If you grind or clench your teeth, wearing a custom-fitted nightguard can help protect them from wear and tear.
- Seek prompt treatment for any issues: If you notice any changes in their fit, appearance, or function, be sure to contact your dentist right away to address the problem.
