A temporary crown falling off is a common issue many people experience during the dental restoration process. This situation can cause anxiety and uncertainty about how to handle it safely. So, what should you do if you find yourself saying: “my temporary crown fell off“? Read the following article to find the most accurate and effective solution!
Why my temporary crown fell off?
A temporary crown is a dental device used to cover and protect a natural tooth while waiting for the permanent porcelain crown to be made. During this period, the temporary crown may fall off for several reasons:
- Ill-fitting temporary crown: If the crown does not fit snugly on the natural tooth, gaps may form between them. Food debris and bacteria can accumulate in these spaces, weakening the adhesive bond and causing the temporary crown to loosen or fall off. In some cases, early gum irritation may also appear, similar to concerns many patients have about conditions like black gum line around crown.
- Weak dental adhesive: The temporary crown is attached to the tooth using specialized dental cement. If the adhesive quality is poor or the crown is frequently exposed to hot and cold foods, the bond will weaken over time, leading to detachment.
- Chewing too hard: Habits such as biting down too forcefully or chewing predominantly on one side can damage the temporary crown. Hard foods like nuts, sunflower seeds, beef jerky, or hard candy can exert strong pressure, causing cracks or dislodgement.
- Improper oral hygiene: Brushing too aggressively or pulling dental floss vertically can loosen the temporary crown, potentially causing it to come off completely.
- Wearing the temporary crown for too long: Temporary crowns are designed for short-term use while waiting for the permanent crown. If worn for an extended period, the adhesive can lose its strength, increasing the likelihood of detachment.

What to do if my temporary crown falls off?
If your temporary crown falls off, remain calm; this is a common occurrence and usually doesn’t pose a serious risk to your oral health. However, it’s important to follow the right steps to protect your tooth and prevent further complications:
- Find the temporary crown: If your crown has fallen onto the floor or another surface, locate it immediately. Check to see if it is still intact by looking for any cracks, chips, or other damage before attempting to reuse it. This is particularly important because some patients may confuse small fractures with issues similar to chipped porcelain crowns, even though the materials used in temporary crowns are different.
- Clean the temporary crown: Once you find it, gently rinse the crown with warm water to remove any dirt or debris. Avoid using harsh cleaning agents. If the crown is damaged, store it in a clean plastic container or sealed bag and bring it to your dental clinic.
- Check for oral injuries: After the crown falls off, your natural tooth or gum may become irritated or slightly injured, especially while chewing. Carefully examine your mouth, and if you experience any discomfort or soreness, consult your dentist. They may recommend applying orthodontic wax or another soothing agent to protect the exposed area.
- Reattach the temporary crown: If the crown is still usable, your dentist will thoroughly clean your tooth and reattach the crown using professional dental adhesive. This will restore normal chewing and speaking functions until your permanent crown is ready.
- Maintain proper oral hygiene: After the temporary crown is reattached, rinse your mouth several times daily with a specialized mouthwash to remove food particles and reduce bacterial buildup. Keeping your mouth clean helps prevent tooth decay and ensures that the temporary crown remains securely in place.

Is a fallen temporary crown considered a dental emergency?
In dentistry, a fallen temporary crown is generally not classified as a dental emergency. If the crown remains intact and functional, it can typically be reattached without any issues. However, it’s important to act quickly and with care. Without the crown, the exposed tooth beneath is vulnerable to infection, gum damage, and sensitivity. Additionally, you may experience difficulties when chewing or speaking during this time.
In summary, if your temporary crown falls off, contact your dentist as soon as possible. They can guide you on how to protect the exposed tooth and create an effective treatment plan to prevent complications.

Ways to prevent a temporary crown from coming off
Here are several effective strategies to help prevent your temporary crown from coming loose:
- Eat soft foods and chew gently: To minimize the risk of the crown loosening or falling off, stick to soft foods like soups, porridge, and mashed vegetables. Avoid sticky, hard, or chewy foods that could dislodge the crown.
- Avoid chewing on the crown side: For the first few days after receiving your temporary crown, avoid chewing on that side of your mouth. The adhesive needs time to fully set, and excess pressure can cause the crown to come off.
- Maintain proper oral hygiene: Use a soft-bristled toothbrush and brush gently, moving from top to bottom and inside to outside. Avoid vigorous brushing near the crown area, and be cautious when using dental floss to prevent loosening the crown.
- Avoid teeth grinding and biting hard objects: Grinding your teeth or biting hard objects (like ice, pens, or fingernails) is a common cause of temporary crowns falling off. Be mindful and try to break these habits.
- Attend regular dental check-ups: Your dentist will likely schedule follow-up visits after placing a temporary crown. Make sure to keep these appointments so they can check for any looseness or adhesive issues and address them before the crown falls off.

FAQ
Can I brush my teeth if my crown fell off?
Yes, you can brush your teeth after your temporary crown falls off. However, be gentle and use a soft-bristled toothbrush to avoid irritating the exposed tooth or gums. Don’t scrub the affected area harshly. After brushing, rinse with salt water or an antiseptic mouthwash to keep the area clean and prevent bacterial buildup.
How long can you go if your temporary crown falls off?
If your temporary crown comes off, it’s best to have it reattached or replaced within 1 to 2 days. Waiting too long increases the risk of infection, tooth sensitivity, and gum irritation. The longer the underlying tooth remains exposed, the more likely it is to sustain damage or require additional dental treatment.
