Can a Crown Damage a Tooth? – Debunking Myths

Crowns play a pivotal role in dental care, restoring and protecting damaged teeth. However, myths surrounding their potential to harm teeth persist, often causing unnecessary concern among patients.

Today, we will answer one of the most asked questions about this treatment: Can a crown damage a tooth?

There are multiple myths surrounding this question, and understanding the truth can be crucial for someone who is considering dental crown treatment. 

Join us as we debunk the common myths about whether a crown can damage a tooth and the actual risks associated with dental crown treatment.

What is a Dental Crown?

Dental crowns are tooth-shaped caps placed over a damaged or decayed tooth to restore its shape, size, strength, and appearance. Once it is cemented into place, it fully encases the visible portion of the tooth above the gum line.

Crowns are most commonly used to protect and restore teeth that have been severely decayed, cracked, or weakened. By covering the entire visible portion of the tooth, they provide structural support and prevent further damage while enhancing your smile’s appearance.

Why Would You Need a Dental Crown?

  • To protect a weakened tooth 
  • To restore the original shape and function of a broken or fractured tooth
  • To strengthen and protect a tooth that has undergone root canal treatment
  • To cover large fillings and hold the remaining tooth structure intact
  • To improve the appearance of misshapen, discolored, or poorly aligned teeth
  • To cover dental implants 
  • To provide support and stability for dental bridges

Can a Crown Damage a Tooth? – Common Myths

Myth: Crowns cause tooth decay.

Reality: Crowns themselves do not cause decay. However, improper oral hygiene or decay underneath an ill-fitting crown can lead to decay of the underlying tooth structure. Regular dental check-ups and proper maintenance of your crown can help in preventing this.

Myth: Crowns weaken the tooth they cover.

Reality: When properly placed, crowns actually strengthen the tooth by covering and protecting it from further damage. They distribute biting forces evenly across the tooth, reducing the risk of fractures.

Myth: Crowns lead to nerve damage or sensitivity.

Reality: While sensitivity immediately after crown placement is possible, it is usually temporary and resolves as the tooth adjusts to the new crown. Properly fitting crowns should not cause permanent nerve damage.

Myth: Crowns are purely cosmetic and unnecessary.

Reality: While crowns sure do improve the appearance of a tooth, they are primarily used to restore and protect teeth that are damaged, decayed, or weakened. They are crucial in maintaining oral health and preventing further dental problems.

Myth: Crowns always require tooth extraction.

Reality: Crowns are often used to save and preserve natural teeth. They can be placed over teeth that have received root canal therapy or have large fillings, actually reducing the need for extraction.

Myth: Crowns are uncomfortable or easily dislodged.

Reality: Modern dental crowns are designed to fit snugly and comfortably over teeth. With proper care and maintenance, they should not cause discomfort or become dislodged under normal circumstances.

How to Care for Your Tooth with a Crown

Brush & Floss Daily

Use a soft-bristled toothbrush and fluoride toothpaste to gently brush your teeth at least twice a day. Use dental floss or interdental cleaners to carefully clean along the sides of the crown and between teeth.

Be Gentle

Avoid using excessive force when brushing and flossing around the crown to prevent loosening or dislodging it. Gentle, circular motions with the toothbrush and careful maneuvering of floss will be more than enough.

Avoid Sticky or Hard Foods

Refrain from chewing on hard objects like ice, hard candies, or pens, as these can potentially damage the crown or cause it to come loose. Similarly, sticky foods can stick to the crown and increase the risk of decay.

Protect Your Crown

If you grind your teeth or participate in contact sports, consider wearing a night guard prescribed by your dentist. This protective device helps cushion the teeth and crown from the forces of grinding or clenching during sleep.

Regular Dental Check-Ups

Visit your dentist for routine check-ups and professional cleanings. Your dentist can inspect the crown for any signs of wear, decay, or damage and address any issues promptly.

Quit Smoking

Smoking and using tobacco products can stain and weaken dental crowns over time. Quitting smoking or reducing tobacco use can help preserve the appearance of your crowns and make sure that they last longer.


The answer to the question, “Can a crown damage a tooth?” solely depends on the expertise of the dentist who applies the crown to the tooth and on your oral care regime. 

Dental crowns offer many benefits for damaged, discolored, or fractured teeth. They can help restore a tooth’s functionality and prevent further damage. However, crowns can sometimes pose risks and challenges if not properly placed or cared for. 

But all of these risks can be minimized or avoided with proper dental care, regular check-ups, and adherence to your dentist’s recommendations for oral hygiene and maintenance.

No, a properly placed dental crown does not cause decay or weaken the underlying tooth. In fact, crowns are used to protect and strengthen teeth that are damaged, cracked, or have undergone extensive decay.
Dental crowns are durable and can last for many years with proper care and maintenance. However, they may eventually need replacement due to normal wear and tear, changes in the underlying tooth structure, or if the crown becomes damaged or dislodged.
