A cracked filling or a suddenly missing crown has a special talent for happening at the worst time—right before a meeting, during dinner, or when you’re traveling. Still, the good news is this: most of the time, you can protect the tooth safely at home for a short period.
The goal isn’t to “fix it forever.” Instead, your job is to reduce sensitivity, keep the area clean, and avoid damage until a dentist can properly repair it. Done right, a temporary solution can keep you comfortable. Done wrong (hello, random glue), it can turn a simple re-cement into a bigger procedure.
At White Swan Dental Clinic, we see this situation often—and with the right steps, it usually stays manageable.
First, what’s actually happening?
When a filling cracks
A filling can chip, fracture, or loosen. Sometimes you feel a sharp edge. Other times, it’s a “weird bite” feeling or sudden sensitivity to cold water.
When a crown comes off
A crown acts like a protective cover. If it becomes loose or falls off, the tooth underneath comes out and causes pain. Moreover, if food particles constantly get trapped in the gap, the surrounding gums can quickly become infected
In any case, this is not the time for conducting experiments. Instead, keep it simple and safe. Looking for a Dental Clinic in Business Bay?
The quick rule: Protect, don’t “permanently bond”
Temporary care should:
- Lightly cover the area.
- Stay away from strong chemicals
- Avoid changing your bite
- Avoid forcing anything into place
Important:If you use nail glue, super glue, or any other adhesive, there is a chance it could get into your mouth, making it difficult to properly align your teeth.
What to do immediately (5-minute action plan)
- clean gently
Just use water. Use warm salt water if your gums hurt. A glass of warm water and half teaspoon of salt added to it. - Save the crown or broken piece
If the crown comes out, store it in a clean container. Don’t scrub it aggressively. - Chew on the other side
This single action stops many unintended damages. - avoid very hot, very cold, and very sticky foods
Sensitivity increases with temperature extremes.. Sticky foods can pull temporary material out. - Book a dental visit soon
It’s more likely that your tooth or gum will get sore if you wait too long.
If you have a cracked filling: safe temporary fixes
A cracked filling can feel minor at first. Even yet, minor fractures can grow into bigger breaks, especially if you keep chewing on it.
Step-by-step
Step 1: Clean mildly
Brush as usual, but slow down near the tooth. Then rinse.
Step 2: Smooth sharp edges
If a sharp edge hurts your tongue or cheek, put tooth wax on it. This is the kind of wax that comes with orthodontic treatment. Put some wax on the rough spot and press it down.
Step 3: Consider a temporary filling material
Pharmacies often sell temporary filling kits (temporary dental cement). Used correctly, they can cover the gap and reduce sensitivity until your appointment. Get details on Best Dental Clinic for Teeth Filling.
How to use it safely
- Wash hands, dry the tooth gently (as much as possible)
- Use a small amount—don’t overpack
- Bite down gently to check the bite
- If it feels “high” (your teeth hit it first), remove it and use less
What NOT to do for a cracked filling
- Don’t shove toothpicks into the gap (it irritates gums and can widen the space)
- Don’t keep testing it with hard foods
- Don’t ignore pain that’s increasing day by day
If your crown fell off: safe temporary options
When a crown comes off, two things matter most:
- protecting the exposed tooth
- keeping the crown safe (because it may be reusable)
Step-by-step
Step 1: Rinse the crown and your mouth
Use water only. Stay away from harsh chemicals.
Step 2: Check if it seats easily (no force)
If it comes naturally and seems stable, you might be able to put it down for a while.
Step 3: Use a pharmacy-grade temporary cement
If you choose to re-seat it:
- Use temporary dental cement (not permanent glue)
- Apply a small amount inside the crown
- Seat it gently
- Remove excess carefully
Floss tip: Slide floss out sideways instead of pulling upward, so you don’t lift the crown. Get details on Dental Crowns.
If the crown doesn’t fit back
Don’t force it. Store it safely and come in. Forcing can chip the tooth, crack the crown, or irritate the gum.
Comfort and pain control (safe, simple)
If you’re sore or sensitive, these help:
- Soft foods for a couple of days (eggs, rice, pasta, smoothies—not icy cold)
- If you experience gum swelling, rinse your mouth with warm salt water.
- If you have sharp sensitivity you have to avoid acidic foods like citrus, soda
- You can use sensitive toothpaste and apply a small dab on the tooth for a few minutes before swelling
If the pain gets worse, burns, or keeps you awake, don’t wait it out. That could mean you have a deeper problem or pain. Looking for a General Dentistry in Business Bay?
What to eat (and what to skip) until you’re treated
Safer choices
- Soups (warm, not boiling)
- Yogurt, oats, bananas
- Soft rice dishes
- Scrambled eggs
- Well-cooked vegetables
Skip these for now
- Nuts, hard crusty bread
- Popcorn (kernels are trouble)
- Sticky candy, chewing gum
- Ice and very crunchy snacks

What we do at White Swan Dental Clinic
When you come in, we typically:
- Examine the tooth and gum line carefully
- Check the bite (a big deal with crowns and temporary materials)
- Decide if the crown can be re-cemented or needs replacement
- Replace or repair the filling properly
- Look for decay under the crown/filling (common if a gap stayed open)
- Only recommend extra treatment if it is really necessary, such as if the nerve is injured.
The most crucial factor is that a good repair will allow you to resume regular chewing and protect the tooth for a long time.
