A filling falls out at the worst possible time. You’re halfway through lunch when you feel something hard and metallic on your tongue, and the sharp edge of your tooth suddenly exposed sends a wave of concern through you. This moment can feel unsettling, but understanding what to do next transforms panic into action.

At Red Rock Dental, Dr. McCaffrey and Dr. Booker have helped countless Las Vegas patients handle this exact situation with over 20 years of combined experience. Our team treats dental emergencies seriously and strives to accommodate you immediately, providing the care you need when unexpected dental issues arise.

What Should You Do After Losing a Filling? 

Call your dentist right away. Even if you’re not experiencing severe pain, the exposed tooth is susceptible to further damage and decay. Protect the exposed tooth by avoiding chewing on that side of your mouth to avoid additional damage.

If you’re experiencing discomfort, over-the-counter pain medication can provide temporary relief. Rinsing your mouth with salt water keeps the area clean and reduces inflammation. Temporary dental filling kits available at pharmacies can cover the exposed area for a short time, though these aren’t permanent solutions.

Why Dental Fillings Fall Out

Several factors contribute to a lost filling. Decay can develop around the edges of an old filling, compromising its hold on the tooth. The materials used to restore your tooth face constant pressure from chewing and temperature changes from hot and cold foods.

Biting down on something hard, like ice or a popcorn kernel, can dislodge even a well-placed filling. Teeth grinding during sleep places excessive force on dental work, gradually loosening it. Sometimes, the filling simply reaches the end of its lifespan, which typically ranges from 5 to 15 years depending on the material used.

What to Expect During Your Dental Visit

Dr. McCaffrey will examine the tooth to assess the extent of damage and decide the best course of action. Digital X-rays may be necessary to check for decay under the surface or damage to the tooth’s root.

Treatment Options Available

If the tooth is otherwise healthy, your dentist will clean out any decay, prepare the cavity, and place a new filling. Modern filling materials like composite resin can be matched to your natural tooth color, providing both strength and appearance. The procedure typically takes less than an hour and is completed in a single visit.

When significant tooth structure has been lost or the remaining tooth is weakened, a crown may be necessary instead of another filling. A crown surrounds the entire visible portion of the tooth, providing protection and preventing future fractures.

Managing Discomfort at Home

Sensitivity after losing a filling is normal. The inner layers of your tooth, which were previously protected, are now exposed. Several strategies help you manage this discomfort until your appointment:

• Soft foods: stick to room-temperature foods and avoid anything sticky, crunchy, or chewy.
• Temperature awareness: cold foods and drinks may cause sharp, shooting pains, so avoid extreme temperatures.
• Sugar caution: sweet foods can trigger discomfort as sugars contact the vulnerable tooth structure.
• Gentle cleaning: brush carefully around the affected tooth and use warm salt water rinses after meals.

These steps prevent bacteria from accumulating in the exposed cavity, which could lead to decay or infection before your repair appointment.

Preventing Future Filling Loss

Routine checkups allow your dentist to monitor existing fillings and identify potential problems before they become emergencies. Good oral hygiene prolongs the life of your dental work. Brushing twice a day with fluoride toothpaste and flossing once daily, according to recommendations from dental professionals, removes plaque and protects both your natural teeth and your dental restorations.

Avoid habits that stress your teeth. Don’t use your teeth as tools to open packages or crack nuts. If you grind your teeth at night, ask about a night guard to protect your teeth and dental work from excessive force. Be mindful when eating hard foods like candy, ice, or popcorn kernels.
