Tips to Deal With a Loose Dental Crown

Dental crowns are an excellent solution for protecting, strengthening, and enhancing the appearance of our teeth. However, they can sometimes become loose or come out of place for various reasons. Whilst this rarely constitutes a medical emergency, it can be quite frustrating, particularly if it affects the front teeth. If you find yourself with a loose dental crown, here is what you need to know and do:

Why do dental crowns become loose?

There are many possible reasons why your crown might become loose. If you notice this happening, it is best to consult your dentist without delay to protect the tooth underneath and prevent more serious infections.

Tooth decay beneath the crown

As crowns are made of porcelain or metal alloys, they do not decay; however, the natural tooth structure beneath them remains vulnerable to decay. If areas around the edges of the crown cannot be cleaned properly, bacterial plaque accumulates and may lead to gum recession. As the tooth structure decays, the foundation weakens, and the crown becomes loose or falls out.

Excessive forces and trauma

Sudden forces, such as biting hard objects, or trauma like a fall, can weaken the bond and dislodge the crown.

Teeth clenching and grinding (Parafunctional habits)

Bruxism creates constant pressure, increasing chewing forces and potentially damaging the adhesive or dislodging the crown.

Loss of cement’s properties

Over time, dental cement may weaken or dissolve due to saliva exposure or improper fit, causing the crown to loosen.

Screw loosening in implant-supported crowns

Implant crowns are secured with screws that can loosen over time due to chewing forces.

Incorrect design or preparation process

Improper tooth preparation or crown design can lead to poor fit and eventual loosening.

What to do if your dental crown comes loose

Contact your dentist immediately

Seek professional help as soon as possible to prevent further damage.

Prepare the crown and tooth

• Cleaning: Gently clean the crown interior.
• Check: Test if it fits correctly.
• Drying: Dry both tooth and crown before placing.

Temporary fixation (First aid)

• Temporary dental cement: Use pharmacy kits as directed.
• Alternatives: Use Vaseline or denture glue short-term.
• Pain management: Use temporary cement or painkillers if needed.

Help from a professional

Your dentist will assess and reattach or replace the crown if necessary.

Steps to keep your dental crown from coming loose

Maintain oral hygiene

• Cleaning margins: Prevent plaque accumulation.
• Brushing & flossing: At least twice daily.
• Special tools: Use superfloss or floss holders.

Be mindful of chewing forces

• Avoid hard and sticky foods.
• Manage grinding habits with night guards.

Regular dental check-ups

• Early detection: Identify issues early.
• Professional care: Maintain gum health.

Special precautions for implant-supported crowns

• Force balance: Avoid lateral forces.
• Passive fit: Ensure proper contact with adjacent teeth.
