How to Fix a Loose Dental Crown At Home

How to Fix a Loose Dental Crown At Home

A dental crown is a common dental restoration that is used to protect and strengthen a damaged tooth. However, sometimes a dental crown may become loose or dislodged, causing discomfort and potential dental issues. 

In this comprehensive guide, we will walk you through the process of fixing a loose dental crown at home. With our step-by-step instructions and expert tips, you’ll be able to address this issue promptly and effectively. Dental crowns can become loose due to various reasons. Some common causes include:

Tooth Decay: 

If the underlying tooth structure supporting the crown is affected by decay, it can weaken the bond between the crown and the tooth.

Trauma or Injury: 

A blow to the face or a significant impact on the dental crown can cause it to loosen or dislodge.

Age and Wear: 

Over time, the cement used to secure the crown may degrade, leading to its loosening.

Incorrect Fit: 

If the dental crown is not properly fitted or if there are issues with the bite alignment, it can contribute to the crown becoming loose.

Is It Safe to Fix a Loose Dental Crown at Home?

While it is possible to fix a loose dental crown at home, it is essential to exercise caution. It is always recommended to consult your dentist before attempting any DIY fixes. 

However, if you are unable to reach your dentist immediately or if you experience minimal discomfort, there are temporary solutions you can try at home. 

Remember, these fixes are temporary and should not replace professional dental care.

Materials You Will Need:

Before you begin the process of fixing a loose dental crown at home, gather the following materials:

  • Dental mirror
  • Dental floss
  • Toothbrush
  • Toothpaste
  • Dental adhesive (available at most pharmacies)
  • Cotton swabs
  • Tweezers
  • Dental wax (optional)

Step-by-Step Guide to Fix a Loose Dental Crown

A loose crown can cause other complications like decay under the crown or damage to neighboring teeth. This guide is intended for emergency situations when immediate professional dental care isn’t available.

1. Remove the Crown

Use a dental mirror to carefully examine the loose dental crown. Gently grasp the crown with your fingers or a pair of clean tweezers and try to remove it. Be cautious not to apply excessive force, as you may damage the crown or the tooth structure.

2. Clean the Crown and Tooth

Thoroughly clean both the inside of the crown and the tooth that it fits onto. Use a toothbrush and toothpaste to brush the tooth, removing any debris or residue. Rinse your mouth with water to ensure a clean surface.

3. Apply Dental Adhesive

Apply a small amount of dental adhesive to the inner surface of the crown. Be sure to follow the instructions provided with the adhesive and avoid using excessive amounts. Dental adhesives are designed to provide temporary fixation for dental restorations.

4. Reposition the Crown

Carefully place the crown back onto the tooth, ensuring it is aligned properly. Gently bite down to ensure a secure fit. Avoid chewing on the crown excessively, as it may cause further loosening.

5. Bite Down Gently

Hold the crown in place by biting down gently on a piece of cotton or a dental roll for a few minutes. This will help the adhesive bond the crown to the tooth effectively.

6. Remove Excess Adhesive

Using dental floss or a cotton swab, remove any excess adhesive that may have oozed out from the margins of the crown. This will help prevent discomfort or irritation.

Alternative Solutions for Temporary Relief (for a Loose Dental Crown)

1. Dental Wax:

Dental wax is a soft, moldable material often used to cover sharp orthodontic wires to prevent them from cutting the mouth.

If the crown is missing and you’re unable to reattach it, you can mold a small amount of dental wax over the exposed tooth. This can help protect the tooth and surrounding tissue from irritation.

2. Temporary Filling Material:

This is a putty-like substance designed to fill cavities or cover exposed teeth temporarily.

Mold the material over the affected tooth to protect it until you can visit a dentist.

3. Clove Oil:

Clove oil has been used traditionally for dental pain relief due to its eugenol content, which is a natural anesthetic.

A few drops can be applied to a cotton ball and dabbed on the affected area for temporary pain relief.

4. Over-the-Counter Pain Relievers:

Non-prescription pain relievers can help reduce pain and inflammation.

Follow the recommended dosage as listed on the label. Common options include ibuprofen or acetaminophen.

5. Salt Water Rinse:

A warm salt water rinse can help clean the area and reduce pain and swelling.

Dissolve half a teaspoon of salt in 8 ounces of warm water, swish around the mouth for 30 seconds, and spit it out.

Precautions after Temporary Fix (for a Loose Dental Crown)

After having a temporary fix for a loose dental crown, it’s vital to take certain precautions to ensure proper healing and prevent further damage.

  1. Steer clear of foods that require a strong biting force like raw carrots, nuts, or hard candies. These could further dislodge or damage the temporarily fixed crown.
  2. Foods such as chewing gum, caramels, or sticky candies can easily pull off the crown again.
  3. Hot drinks like coffee or cold treats like ice cream can cause sensitivity or pain on the exposed tooth beneath the crown. Avoid consuming extremely hot or cold beverages and foods.
  4. To reduce the risk of the crown coming off again, try to chew on the opposite side of your mouth.
  5. Continue to brush gently around the affected tooth, using a soft-bristled toothbrush. Consider rinsing with a saltwater solution or antimicrobial mouthwash to keep the area clean and prevent potential infection.


Fixing a loose dental crown at home can provide temporary relief until you can see your dentist. However, it is important to remember that these solutions are temporary and should not replace professional dental care. If you experience persistent discomfort or have difficulty fixing the crown at home, it is essential to seek prompt dental attention. Your dentist will assess the situation, address any underlying issues, and provide the necessary treatment to ensure the long-term stability of your dental crown.
