Lost Filling or Crown? Here’s What Glendale Patients Should Do Before Seeing Us

It’s a startling moment: you’re chewing, and you feel something hard and unnatural in your mouth that definitely isn’t food. Your tongue probes the area, only to find a new, hollow space where a filling used to be. Or perhaps you’re flossing, and a dental crown suddenly pops loose. A lost filling or crown is a common dental issue, but it can cause immediate concern and discomfort. What does this mean for your tooth? Is it a true emergency? What should you do next? For our patients in Glendale, CA, knowing the right steps to take can prevent pain, protect the tooth from further damage, and make the restoration process smoother. At Infinite Dental Wellness, we want to equip you with clear, practical instructions for managing this situation before you can get to our office. This guide will cover immediate actions, temporary home care solutions, crucial things to avoid, and why seeking prompt professional help is essential. Handling this correctly from the moment it happens can make all the difference. This article provides a step-by-step plan for when a filling comes out or a crown falls off. We will explain how to manage the situation, what to use for temporary protection, and why delaying a visit to the dentist is a bad idea.

The First 30 Minutes: Immediate Steps After Losing a Filling or Crown

The moments right after a restoration comes loose are critical. Your calm and careful actions can protect the exposed tooth and manage any initial discomfort.

Step 1: Remove the Restoration from Your Mouth

First and foremost, carefully remove the lost crown or piece of filling from your mouth. You want to avoid accidentally swallowing it or, worse, inhaling it into your lungs, which is a serious medical emergency. Once you have it, set it aside in a safe place.

Step 2: Inspect the Crown or Filling

Take a quick look at the object.

• Is it a Crown? If a crown came off, is it mostly hollow? Is it intact, or does it look like there’s a piece of your natural tooth stuck inside it? An intact crown might be able to be re-cemented. If the crown is broken or has tooth structure inside, it’s a sign of a more significant problem like underlying decay or a tooth fracture.
• Is it a Filling? A lost filling will look like a solid chunk of material, either silver (amalgam) or tooth-colored (composite). It cannot be put back in, but its size can give you an idea of how large the hole in your tooth is.

Step 3: Rinse Your Mouth Gently

Rinse your mouth with warm salt water. Mix half a teaspoon of salt into a glass of warm water and swish it around gently. This will help clean the area, remove any food debris from the exposed cavity, and soothe the gum tissue, which might be irritated. Do not rinse aggressively.

Step 4: Assess Your Pain Level

Your level of pain is a key indicator of the situation’s urgency.

• No Pain or Mild Sensitivity: If the tooth isn’t hurting, that’s a good sign. The dentin (the layer beneath the enamel) is exposed, but the nerve-filled pulp is likely still protected. You may feel some sensitivity to air or temperature.
• Sharp or Throbbing Pain: If you are experiencing significant pain, it’s a sign that the dentin is highly sensitive or, in more severe cases, that the pulp is exposed or inflamed. This elevates the urgency.

Step 5: Call Your Dentist Immediately

Regardless of your pain level, this is the most important step. Contact your dental office right away. If you’ve experienced a lost filling in Glendale, CA, or had a crown fell off, an emergency dentist should be your first call. Explain exactly what happened. Let the scheduler know:

• Which tooth it is.
• Whether it was a filling or a crown.
• If you have the crown and if it appears intact.
• Your pain level.

This information will help the dental team assess the urgency and schedule you for the appropriate appointment. Even if you aren’t in pain, the tooth is weakened and vulnerable, and you should be seen as soon as possible.

At-Home Care: Protecting Your Tooth Before Your Appointment

After you’ve made your dental appointment, you may have to wait a day or two to be seen. During this time, your main goal is to protect the compromised tooth from damage, sensitivity, and infection. Here are safe, temporary measures you can take at home.

For a Lost Filling

When a filling falls out, it leaves behind an open cavity in your tooth. This space can trap food and bacteria, and the exposed dentin can be very sensitive.

Temporary Filling Material

You can find temporary dental filling material at most pharmacies. It’s usually a zinc oxide-based paste that you can use to temporarily plug the hole.

• How to Use It: First, make sure the tooth is clean and dry. You can use a small piece of cotton to gently dry the cavity. Take a small amount of the temporary material, roll it into a ball, and press it gently into the hole. Bite down carefully to ensure it’s not too high and doesn’t interfere with your bite. The material will set over a short period.
• Important Note: This is strictly a temporary fix. It is not strong, will wear down quickly, and does not perfectly seal the tooth. It is only meant to protect the tooth and reduce sensitivity for a very short time.

Dental Wax

If you can’t find temporary filling material, a small piece of dental wax (the kind used for braces) or even sugar-free chewing gum can be used in a pinch. This can help cover the exposed area and smooth over any sharp edges of the tooth that might irritate your tongue.

For a Lost Crown

If your crown has fallen off, you have a different situation. The underlying tooth has been prepared and shaped specifically for that crown, leaving it weak and exposed.

If You Have the Crown and It’s Intact

Your dentist may be able to re-cement the original crown, so it’s important to keep it safe. Store it in a small, clean container. Before your appointment, you might be able to temporarily reseat it.

• Clean the Crown and Tooth: Gently clean the inside of the crown with a toothbrush, and carefully clean the exposed tooth. Make sure both are dry.
• Use a Temporary Cement: Pharmacies sell temporary dental crown cement. Do NOT use super glue or any other household adhesive. Apply a small amount of the temporary cement inside the crown and carefully place it back onto your tooth, making sure it is aligned correctly.
• Check Your Bite: Bite down gently but firmly. If the bite feels high or “off,” remove the crown, clean it, and try again with less cement. Excess cement will squeeze out the sides; wipe this away.
• Denture Adhesive as an Alternative: If you cannot find temporary crown cement, a small dab of denture adhesive (like Fixodent or Poligrip) can also work to hold the crown in place for a few hours.

If the Crown is Broken or You Don’t Have It

If the crown is lost or damaged, you cannot reseat it. The priority is to protect the underlying tooth, which is now very vulnerable.

• Protect the Tooth: The prepared tooth will be sensitive and have a rough texture. You can cover it with temporary filling material or dental wax to reduce sensitivity and prevent it from shifting.
• Be Extremely Careful: A tooth prepared for a crown is not meant to withstand chewing forces on its own. It can easily fracture. Avoid chewing on that side of your mouth entirely.

What NOT to Do: Common Mistakes to Avoid

What you don’t do is just as important as what you do. Making the wrong move can cause more damage, lead to intense pain, or make the final restoration more complex and costly.

DO NOT Use Super Glue or Household Adhesives

This is the most critical warning. It might seem like a quick, strong fix, but using super glue to reattach a crown is a terrible idea for several reasons:

• It’s Toxic: Household glues contain chemicals that are not meant to be in your mouth and can damage the tooth and surrounding gum tissue.
• It Causes an Improper Fit: You will never be able to seat the crown perfectly with super glue. Even a microscopic misalignment can throw off your bite, leading to jaw pain, damage to opposing teeth, and potential fracture of the crowned tooth.
• It Makes Professional Repair Impossible: Once super glue sets, it’s incredibly difficult for a dentist to remove the crown without destroying it and potentially damaging the underlying tooth. What might have been a simple re-cementing procedure will now automatically require a new, expensive crown.

DO NOT Ignore the Problem, Even if It Doesn’t Hurt

A lack of pain is not a sign that everything is okay. When a restoration falls out, the tooth loses its protective layer.

• Risk of Shifting: Your teeth are held in place by their neighbors. When a crown or filling is missing, the adjacent and opposing teeth can start to shift into the empty space. This can happen surprisingly quickly. If the teeth shift, the original crown may no longer fit, and a new one will be needed.
• Risk of Fracture: The remaining tooth structure is weakened. Biting down on something hard can easily cause the tooth to crack or fracture, potentially below the gum line. A simple filling replacement could turn into a situation requiring a crown, a root canal, or even an extraction.
• Risk of Decay and Infection: The exposed dentin is much softer than enamel and more susceptible to decay. Bacteria can quickly lead to a new cavity or, if the pulp is nearby, a painful infection and abscess.

DO NOT Chew on the Affected Side

This might seem obvious, but it’s easy to forget. Chewing on the unprotected tooth puts it at high risk of fracturing. Stick to soft foods and consciously chew on the opposite side of your mouth until you can see your dentist.

Why Do Fillings and Crowns Fall Out? Understanding the Cause

When a restoration fails, it’s rarely a random event. Understanding the underlying cause is key to preventing it from happening again. Your dentist will investigate these possibilities during your visit.

New Tooth Decay

The most common reason for a failing restoration is new decay forming around its edges. A filling or crown does not get cavities, but the natural tooth structure around it can. As bacteria create decay, they eat away at the tooth supporting the restoration, weakening the bond until it comes loose.

Biting and Chewing Forces

Over years of use, the constant pressure from chewing and biting can cause the dental cement holding a crown to break down. Similarly, a filling can develop microfractures and eventually fail. This is especially true for patients who grind their teeth (bruxism) or chew on hard items like ice or pens.

Failure of the Dental Cement

The cement used to bond a crown is designed to last for many years, but it isn’t permanent. Over time, it can wash out or dissolve, breaking the seal between the crown and the tooth.

Trauma or Injury

A sudden blow to the face or biting down on something unexpectedly hard (like a popcorn kernel or olive pit) can be enough to dislodge a filling or crown.

Poor Oral Hygiene

Neglecting to brush and floss properly allows plaque and bacteria to accumulate around the margins of your restorations. This is a primary cause of the new decay that leads to failure.

Age of the Restoration

Nothing lasts forever. Dental restorations have a typical lifespan. Amalgam fillings might last 15 years or more, while composite fillings may last 5-7 years. Crowns can last anywhere from 5 to 20+ years, depending on the material and care. An old restoration is simply more likely to fail.

Professional Treatment: Restoring Your Tooth at Infinite Dental Wellness

When you come to our office, we will start by examining the tooth, taking an X-ray, and discussing your symptoms. Our goal is to provide a durable, long-term solution.

For a Lost Filling

The treatment for a lost filling in Glendale, CA, usually involves placing a new one.

1. Assessment: We will check for any new decay and ensure the tooth is structurally sound.
2. Cleaning: The area will be numbed, and any remaining old filling material and new decay will be removed. The tooth is then thoroughly cleaned.
3. New Filling: A new filling will be placed. We often use tooth-colored composite resin, which is bonded directly to the tooth for a strong and aesthetic result. If the filling was very large, the tooth might now be too weak for another filling. In this case, a more protective restoration like an onlay or a full dental crown may be recommended.

For a Lost Crown

When your crown fell off, our emergency dentist will first determine if the original crown can be reused.

1. Re-cementing the Original Crown: If the crown still fits well, the underlying tooth is healthy, and your bite is correct, we may be able to simply re-cement it. This is the quickest and most cost-effective solution. We will thoroughly clean the tooth and the inside of the crown before bonding it back into place with permanent dental cement.
2. Fabricating a New Crown: A new crown will be necessary if:
   • The old crown is damaged or no longer fits properly.
   • There is new decay on the underlying tooth that needs to be removed, changing its shape.
   • The tooth itself has fractured. The process involves preparing the tooth, taking a new impression, and creating a new custom crown that fits perfectly and restores your bite.

When More Treatment is Needed

Sometimes, a lost restoration reveals a more serious problem. If decay or a fracture has reached the pulp, you may need a root canal treatment to save the tooth before a new filling or crown can be placed. If the tooth is fractured beyond repair, an extraction might be the only option to protect your oral health.
