# Filling fell out? What to do right now and when to call your dentist A filling that fell out leaves a hole in the tooth, and that hole fills with bacteria fast. Rinse gently, protect the tooth with pharmacy temporary filling material if you like, chew on the other side, and call your dentist within a day or two. Most lost fillings are replaced in a single visit. - Fuente: https://neoladental.com/blog/filling-fell-out-what-to-do - Autor: Dr. Josaida Contreras, DDS - Publicado: 2026-10-14 - Revisado: 2026-10-14 - Idioma: en - Consultorio: Neola Dental, 825 US-27 #104, Minneola, FL 34715 ยท (352) 717-2177 --- If a filling fell out, rinse your mouth with warm water, save any pieces, avoid chewing on that tooth, and call your dentist within a day or two. The hole left behind traps food and bacteria, and decay can move deeper quickly. Most lost fillings are replaced in one visit, and the sooner you come in, the more of your natural tooth we can keep. If the tooth is cracked or badly broken down, we may suggest a [crown](/crowns) instead of a new filling. Until then, pharmacy temporary filling material can cover the hole, and you should chew on the other side and skip sticky, hard, hot and cold foods. Never put super glue or any household adhesive in the tooth. Call the same day if you have swelling, fever, or strong pain. Need to be seen? Call Neola Dental at (352) 717-2177 or [book online](/schedule). Tell the front desk a filling came out and whether the tooth hurts. That helps us decide how quickly to fit you in. ## What should I do first when a filling falls out? Work through these steps in order. Each one takes a minute or less. First, check that nothing went down the wrong way. A small filling is easy to swallow without noticing. If you are coughing or struggling to breathe, get medical care right away. Second, rinse. Swish warm water around your mouth, gently, to clear food and loose fragments. If the gum is tender, use warm salt water, about half a teaspoon of salt in a glass of water. Third, look for the filling or any pieces and put them in a clean container. We rarely reuse an old filling, but seeing it tells us how it failed. Fourth, look at the tooth in a mirror. Note any dark area, crack, or sharp edge so you can describe it on the phone. You do not need to diagnose anything. Fifth, protect the tooth, as the next sections explain, and call the office. ## What should I never do when a filling comes out? A few well-meant fixes cause real damage. Skip these. Do not use super glue, nail glue, or any household adhesive. These products are not made for the mouth. They can irritate the gum and the tooth, and glue packed into the hole makes the tooth harder to clean and repair. Our guide to a [crown that fell off](/blog/crown-fell-off-what-to-do) covers the same rule. Do not pack the hole with candy, wax, chewing gum that contains sugar, or anything sticky. Sugar feeds bacteria. Do not poke at the tooth with a pin or toothpick. Probing pushes food and bacteria deeper. Do not keep chewing on that side. A weakened tooth can crack under normal chewing, and a crack turns a simple filling into a larger repair. Do not ignore it because it feels fine. Pain is a late sign of decay, not an early one. ## Can I use temporary filling material from the pharmacy? Yes, for a day or two. Most pharmacies sell temporary filling material in the dental aisle. It can cover a sensitive hole and keep food out until you are seen. Use it as the package directs. Rinse and dry the tooth as well as you can, press a small amount into the hole, and close your teeth gently to check your bite. If the tooth feels high, remove some material before it sets, because a high temporary filling hurts when you chew. Treat it as a bridge to your appointment, not a repair. It washes out quickly, it does not seal the way a real filling does, and decay keeps moving underneath it. Do not use it if there is swelling, a bad taste, pus, or throbbing pain. Those signs point to infection, and covering the area can trap bacteria inside. Call us instead. ## Why do fillings fall out? Fillings do not last forever. The American Dental Association notes that fillings can weaken, fracture, and leak around the edges over time, and that bacteria collect in those tiny gaps. A few causes come up again and again. Wear and age. Over years of chewing, the edges chip and the seal loosens. New decay under or around the filling. Decay can start at the edge where the filling meets the tooth, then undermine the filling from beneath until it lets go. If you want to know what that looks like, our guide on [how to tell if you have a cavity](/blog/how-to-tell-if-you-have-a-cavity) lists the signs. A cracked tooth. If the tooth around the filling cracks, the filling loses its support and pops out with a piece of tooth attached. A heavy bite. Clenching or grinding puts far more force on a filling than chewing does. A large filling. The bigger the filling, the less natural tooth remains to hold it, and that is where an inlay, onlay, or crown tends to come in. Sticky or hard food, such as caramel and ice, can also break a filling that was already weak. ## Is a filling that fell out a dental emergency? Usually it is urgent but not an emergency. Without the red flags below, you do not need the ER, but do not wait weeks either. Plan to be seen within a day or two. Our page on [emergency dentistry in Minneola](/emergency-dentist-minneola) covers what counts as an emergency. Call the same day if you have: - Swelling in the gum, cheek, jaw, or face - Throbbing pain that keeps you up at night - Fever, a bad taste, or pus near the tooth - Pain that over-the-counter medicine does not control - A cracked or broken tooth with a sharp edge cutting your tongue or cheek - Bleeding that does not stop on its own If none of those apply, soft foods, warm salt water rinses, and an over-the-counter pain reliever taken as the label directs usually get you through. Then schedule the visit. Sharp pain when you bite down is also a reason to be seen sooner. ## Why is the tooth suddenly sensitive? The filling covered the inner part of the tooth. Without it, the layer underneath, called dentin, is exposed to air, temperature, and sugar. Dentin has tiny channels that lead toward the nerve, which is why cold water or a breath of air can send a quick jolt. That reaction is common, and it is also a clue about depth. A brief zing that passes quickly usually means an irritated nerve. Pain that lingers after the cold is gone, or that wakes you up, suggests deeper involvement and a faster visit. Our article on [tooth sensitivity causes](/blog/tooth-sensitivity-causes) explains how to tell the two apart. ## What happens if I leave it alone? Waiting a few days does little harm in most cases. Waiting weeks or months is different. The hole gets bigger. Food packs into the space, bacteria feed on it, and decay spreads into the tooth, past the point where a filling will hold. The tooth weakens. As more structure erodes, the remaining walls thin out and can break away, which is a bigger repair than a lost filling. The nerve gets involved. Once decay reaches the pulp, the choice moves from a filling to root canal treatment or, in worse cases, extraction. Cleveland Clinic notes that a cavity that reaches the dentin needs a filling, a crown, or another restoration, and that deeper decay can call for root canal therapy. None of this happens overnight, but each week of waiting makes the eventual fix larger. ## What will the dentist do when a filling falls out? The visit usually follows the same pattern. We start by asking what happened and whether the tooth hurts, then examine it and take an X-ray. The picture shows how deep the hole is, whether decay is hiding under the old filling, and whether the tooth is cracked. Next, the dentist numbs the area if needed, then cleans out any decay and the leftover filling material, shapes the tooth, and places the new filling. A tooth-colored composite resin is common for most teeth, though the right material depends on the size and location of the cavity. The ADA encourages patients to talk with the dentist about material options, taking into account the size and location of the cavity, appearance, how long the filling might last, and insurance coverage. Finally, the dentist checks your bite and polishes the filling. Most patients leave the same day. ## Do I need a new filling, an inlay or onlay, or a crown? The answer depends on how much healthy tooth remains, and we decide it after the exam and X-ray. A new filling fits when the tooth is solid and the hole is small to medium. It is the most conservative choice. An inlay or onlay fits when the damage is too large for a filling but the tooth does not need full coverage. An inlay sits within the chewing surface, and an onlay covers one or more cusps. Both are made to fit the tooth and bonded in place, and they support it better than a large filling does. A crown fits when a large part of the tooth is gone, cracked, or weakened, or when the tooth has had root canal treatment. A crown wraps the whole tooth and protects it from splitting. You can learn more on our [crowns](/crowns) page, and our post on [what to do when a crown falls off](/blog/crown-fell-off-what-to-do) covers the opposite situation. If the tooth cannot be saved, we explain the replacement options openly. So it pays to come in promptly. ## Can I eat and brush normally until my appointment? Chew on the other side. Choose soft foods such as eggs, yogurt, oatmeal, soup, pasta, and well-cooked vegetables. Skip sticky foods, hard foods, and anything very hot or very cold, since the exposed dentin reacts to temperature. Keep brushing. Use a soft toothbrush and brush around the area gently rather than avoiding it, since plaque on an exposed tooth speeds up decay. Floss carefully and do not snap the floss into the hole. Rinse with warm salt water after meals, and avoid sugary drinks. If you grind your teeth at night, tell us at the visit. A night guard protects new fillings. ## How much does it cost to replace a lost filling? The cost depends on the size of the filling, the material, the number of surfaces involved, and whether the tooth needs more than a simple replacement. A small replacement costs far less than an inlay, onlay, or crown, and none of these can be priced without looking at the tooth. We do not quote numbers over the phone. After the exam and X-ray you get your options and a written estimate before any work begins. We are a privately owned, non-corporate practice, so the person who explains the plan is the person who treats you. We work with major PPO plans, including Delta, Aetna, MetLife, Cigna, Guardian, BCBS, United Concordia, and Humana, and with Medicare Advantage plans that include dental benefits. Ask the front desk to check your benefits when you call. Our [payment options](/payment-options) page covers other ways to spread out the cost. ## Filling fell out in Minneola or Clermont? how Neola Dental handles it Neola Dental is at 825 US-27 #104, Minneola, FL 34715, minutes from Clermont, Groveland, Winter Garden, Mascotte, Montverde, and the rest of Lake County.

Call within a day or two, even if nothing hurts. The open space collects food and bacteria, and decay can move deeper into the tooth within weeks. If you have swelling, a fever, or throbbing pain, call the same day. ### Is a lost filling a dental emergency? Usually it is urgent but not an emergency. It becomes an emergency if you have facial swelling, fever, pus, severe pain that over-the-counter medicine does not control, or a broken tooth with a sharp edge. Without those signs, plan to be seen within a few days. ### Can I use super glue to put a filling back in? No. Super glue and other household adhesives are not made for the mouth, can irritate the gum, and make the tooth harder to repair. If you need cover before your visit, use temporary filling material from a pharmacy and follow the label. ### Why did my filling fall out? The most common reasons are wear over time, new decay at the edge of the filling, a bite that puts too much force on the tooth, and a crack in the tooth or the filling. Fillings are not permanent, and older ones tend to leak around the edges. ### Will the dentist just put in a new filling? Often, yes. If the tooth is solid, the dentist cleans out any new decay and places a new filling. If too much tooth is missing or cracked, an inlay, onlay, or crown protects it better. We examine the tooth and take an X-ray before recommending anything. ## Sources - [American Dental Association, MouthHealthy - Dental Filling Options](https://www.mouthhealthy.org/all-topics-a-z/dental-filling-options) - [American Dental Association, MouthHealthy - Cavities](https://www.mouthhealthy.org/all-topics-a-z/cavities) - [American Dental Association, MouthHealthy - Dental Emergencies](https://www.mouthhealthy.org/all-topics-a-z/dental-emergencies) - [Cleveland Clinic - Cavities (Tooth Decay): Symptoms, Causes and Treatment](https://my.clevelandclinic.org/health/diseases/10946-cavities) - [National Institute of Dental and Craniofacial Research - Tooth Decay](https://www.nidcr.nih.gov/health-info/tooth-decay)
