What Happens When a Filling or Crown Falls Out?

When a filling or crown comes loose or falls out, the underlying tooth structure is suddenly exposed. This exposure can cause intense sensitivity to temperature and pressure, allow bacteria to enter the tooth and cause decay or infection, and lead to further structural weakening that may result in the tooth cracking or breaking under normal biting forces.

The tooth underneath a crown has been shaped and reduced in size to accommodate the restoration. Without the protective covering, it is significantly weaker than a natural, unaltered tooth. Similarly, a tooth with a lost filling has an open cavity that provides a direct pathway for bacteria to reach the inner layers of the tooth.

The longer the tooth remains unprotected, the greater the risk of needing more extensive and expensive treatment. What might be a simple recementation or filling replacement today could become a root canal, extraction, or implant if left untreated for weeks.

Why Fillings and Crowns Fail

Understanding why restorations fail can help you watch for early warning signs and seek care before a complete failure occurs. Here are the most common reasons our Lansing dental team sees:

Decay Underneath the Restoration

New decay can form at the margins where the filling or crown meets the natural tooth. This undermines the bond and causes the restoration to loosen. Regular dental check-ups catch this early.

Normal Wear and Aging

Dental cement and filling materials break down over time. An average filling lasts 7 to 15 years, and crowns typically last 10 to 15 years. As materials age, the seal weakens and failure becomes more likely.

Teeth Grinding (Bruxism)

Grinding or clenching your teeth places excessive force on restorations, especially during sleep. This repetitive stress can crack fillings, break crowns, or loosen the cement bond.

Biting on Hard Objects

Chewing ice, hard candy, popcorn kernels, or using your teeth to open packaging can crack or dislodge restorations. These forces exceed what fillings and crowns are designed to withstand.

Insufficient Tooth Structure

If the original tooth did not have enough healthy structure to anchor the restoration, the bond may fail prematurely. This is common with very large fillings or crowns placed on heavily restored teeth.

Temperature Fluctuations

Repeatedly eating very hot food followed immediately by cold drinks causes dental materials and natural tooth structure to expand and contract at different rates, weakening the seal over time.

Our Treatment Options for Lost Restorations

Emergency Dentist Lansing offers a complete range of restoration services so we can address your specific situation during a single visit whenever possible. Here is what each treatment involves:

Crown Recementation

If your existing crown is intact and the underlying tooth is healthy, we can clean both surfaces, apply new dental cement, and reattach your crown in a single quick visit. This is the simplest and most affordable option when the original crown is in good condition.

New Custom Crown

When a new crown is needed, we prepare the tooth, take precise impressions, and place a durable, natural-looking crown made from porcelain, zirconia, or porcelain-fused-to-metal. The material is selected based on the tooth location, your bite pattern, and your aesthetic preferences.

Composite Filling Replacement

For lost fillings, we remove any new decay, prepare the cavity, and place a new tooth-colored composite filling that bonds directly to the tooth structure. Modern composites are strong, durable, and virtually invisible in the mouth.

Onlay or Inlay Restoration

When the damage is too large for a standard filling but does not require a full crown, an onlay or inlay provides a conservative middle ground. These lab-fabricated restorations fit precisely into the prepared cavity and offer excellent durability.

Temporary Protective Restoration

If a permanent crown requires lab fabrication time, we place a high-quality temporary restoration to protect your tooth from bacteria, sensitivity, and further damage while you wait.

What to Do Until You Reach Our Office

If you lose a filling or crown outside of office hours or cannot get to Emergency Dentist Lansing right away, these temporary steps can protect your tooth until your appointment:

Lost Crown

Try to place the crown back over the tooth using dental cement, denture adhesive, or even a thin layer of toothpaste as a temporary adhesive. Make sure it faces the right direction. Do not use household glue. If the crown does not stay on, bring it with you to your appointment.

Lost Filling

Cover the open cavity with temporary dental filling material (available at most pharmacies under brands like DenTemp or Dentemp). In a pinch, sugar-free chewing gum can serve as a short-term barrier. Avoid chewing on that side.

Managing Sensitivity

The exposed tooth may be sensitive to air, temperature, and pressure. Over-the-counter pain relievers like ibuprofen can help. Avoid very hot or cold foods and beverages. Rinsing with warm saltwater can soothe irritated tissue around the tooth.

Protecting the Tooth

Eat soft foods and chew on the opposite side. Avoid sticky, hard, or crunchy foods that could cause further damage. Be gentle when brushing near the affected tooth to avoid dislodging more material.

When Temporary Measures Are Not Enough

Seek same-day care if the exposed tooth is causing severe pain, you notice swelling or signs of infection around the tooth, the tooth has cracked or broken further, or you swallowed the crown or filling (while generally harmless, you should inform your dentist). Call Emergency Dentist Lansing at (517) 645-3037 and we will get you in as quickly as possible.

Making Your Restorations Last Longer

After we replace your filling or crown, these habits will help extend the life of your new restoration and prevent future emergencies:

Maintain excellent oral hygiene with twice-daily brushing and daily flossing

Wear a night guard if you grind your teeth while sleeping

Avoid chewing ice, hard candy, and other extremely hard foods

Do not use your teeth as tools to open packages or bottles

Visit your dentist every six months for check-ups so early signs of wear are caught

Let your dentist know if a restoration feels rough, loose, or different when you bite

Lost Filling & Crown FAQ

What should I do if my filling falls out?
If a filling falls out, keep the area clean by gently rinsing with warm saltwater. You can temporarily fill the cavity with sugar-free gum or dental cement from a pharmacy. Avoid chewing on that side and call Emergency Dentist Lansing at (517) 645-3037 for a same-day appointment to have it properly replaced.
How long can I wait to replace a lost crown?
You should replace a lost crown as soon as possible, ideally within 24–48 hours. The exposed tooth underneath is vulnerable to decay, sensitivity, and further breakage. If you cannot get to our Lansing office immediately, try to temporarily reattach the crown with dental cement (available at pharmacies).
Why do fillings and crowns fall out?
Fillings and crowns can fall out due to decay forming underneath the restoration, normal wear and tear over time, biting on hard foods, teeth grinding (bruxism), or the cement wearing down. Our Lansing dental team will determine the cause and provide a long-lasting replacement.
Can a lost filling or crown be put back?
Sometimes the original crown can be recemented if it is intact and the underlying tooth is healthy. Fillings generally need to be replaced with new material. At Emergency Dentist Lansing, we assess whether the original restoration can be reused or if a new one is needed, always choosing the most effective option.
How much does crown replacement cost in Lansing?
Recementation of an existing crown typically costs $50–$200. A new dental crown ranges from $500–$1,500 depending on the material. Filling replacements cost $100–$400. We accept Delta Dental of Michigan, BCBS, and all major insurance plans at our Lansing office.
Is a lost filling considered a dental emergency?
Yes, a lost filling is considered a dental emergency because the exposed tooth is vulnerable to bacteria, decay, and further structural damage. The cavity that was filled is now open, and without the protective barrier of the filling, sensitivity and pain can develop quickly. Call Emergency Dentist Lansing for same-day treatment.
How long do dental crowns typically last?
With proper care, dental crowns can last 10 to 15 years or longer. Factors that affect longevity include oral hygiene habits, teeth grinding, biting on hard objects, and the material used. Porcelain and zirconia crowns tend to be the most durable. Regular dental check-ups help us catch early signs of crown wear before failure occurs.
What materials are used for dental crowns?
Modern dental crowns are made from several materials including porcelain (natural-looking, ideal for front teeth), zirconia (extremely strong and tooth-colored), porcelain-fused-to-metal (combines strength with aesthetics), and gold alloy (highly durable for back teeth). Our Lansing team recommends the best material based on the tooth location, your bite, and your preferences.
