Some dental problems are medical emergencies. Get emergency care right away if you have:
- Difficulty breathing or swallowing
- Swelling of the face, jaw, floor of the mouth, or neck — especially if it is spreading
- Swelling that affects your eye or makes it hard to open your mouth
- A high fever combined with mouth or facial swelling
- Bleeding that won't stop after 10–15 minutes of firm pressure
- A knocked-out adult tooth, or an injury to the jaw, head, or face
When in doubt, consider it an emergency and seek care now.
What Happened
A temporary filling is a short-term seal your dentist places over a tooth to protect it between visits. It’s softer and more prone to falling out than a permanent filling, especially if you chew on that side of your mouth, eat sticky foods, or the filling wasn’t fully set. If yours came out, the tooth is now at risk.
Why This Needs Immediate Attention
Temporary fillings protect the interior of your tooth (called the pulp) from bacteria, air, and food debris. When the filling comes out:
- The tooth becomes sensitive. You may notice sharp pain when you bite, or aching when the tooth is exposed to cold air or hot liquids.
- Bacteria can enter. The exposed cavity or prepared tooth can develop an infection, which may lead to more serious problems later.
- The original problem worsens. If the tooth was being treated for decay or after a root canal, leaving it exposed compromises that treatment.
What to Do Right Now
Call your dentist immediately. Don’t wait for your next scheduled appointment. Most dental offices keep emergency slots or can fit you in the same day. Explain that your temporary filling fell out so the office knows to prioritize your call.
If your regular dentist isn’t available, ask for an emergency referral or contact an urgent dental care center.
While You Wait
Avoid chewing on the side of your mouth where the filling came out. Be gentle with that tooth. If you experience sharp pain or swelling in your face or jaw, or if you feel feverish, get urgent care immediately—these can signal infection.
Do not try to re-pack the filling yourself. Over-the-counter filling repair kits may seem convenient, but they don’t seal the tooth properly and can trap bacteria underneath, making the problem worse.
You can rinse your mouth gently with warm salt water to keep the area clean while you wait for your appointment.
What Your Dentist Will Do
Your dentist will examine the tooth to check for decay, damage, or infection. They’ll then replace the temporary filling with a fresh one. Depending on why the tooth was filled in the first place (decay, root canal, crown preparation), they may also discuss the next steps in your treatment plan.
Prevention Tips
- Avoid chewing sticky, hard, or very chewy foods on the side with the temporary filling.
- Don’t use that tooth to bite down on ice or hard objects.
- Be mindful when flossing near the filling—be gentle.
- If you grind your teeth at night, mention this to your dentist; it can cause fillings to loosen.

Frequently asked questions
Can I just put the filling back in myself?
No. Temporary fillings are designed to be placed by a dental professional to seal the tooth properly and protect what's underneath. Trying to repack it yourself can trap bacteria or cause further damage. Call your dentist immediately.
Why is my tooth so sensitive now?
Once the filling comes out, the inside of your tooth (which is much softer than the outer shell) becomes exposed to air, temperature, and bacteria. This sensitivity is normal and underscores why you need prompt care.
What if I can't get in to see my dentist today?
Call your dentist's office right away—many have same-day or emergency slots. If your dentist isn't available, ask for an emergency referral or contact an urgent dental care center. Do not wait; the longer the tooth is exposed, the greater the risk of infection or further damage.
