Losing a filling or crown can be uncomfortable and stressful — but knowing what to do in the moment can reduce pain, protect your tooth, prevent further damage, and help you feel more in control. At Oroville Gentle Dentistry, we understand how unsettling dental emergencies can be, and we’re here to support you with compassionate care and clear guidance whenever possible.

Whether it’s a lost filling, a crown that has come off, or a crown that broke, this guide walks you through what to do right now — from practical tips to gentle self-care solutions until your appointment.

What Happens When a Filling or Crown Comes Off?

When a filling or crown is lost, the underlying tooth is left exposed. This can lead to:

  • Tooth sensitivity to hot, cold, or sweet foods
  • Pain or discomfort when chewing
  • Increased risk of infection or decay
  • Sharp edges that can irritate your tongue or cheek
  • Food getting packed between your teeth

Leaving the area unprotected can cause additional damage or weaken the tooth further, so taking steps to temporarily protect it is recommended.

Step-By-Step: How to Protect Your Tooth After a Lost Crown

1. Rinse Your Mouth Gently

Start by rinsing with warm salt water to cleanse the area and reduce bacteria:

How to make a salt water rinse:

  • 1/8 teaspoon of salt
  • 1 cup warm (not hot) water

Swish gently and spit. This helps keep the exposed surface clean.

2. Inspect the Tooth — But Don’t Panic

Look in a mirror and see what’s going on:

  • If the crown is intact, keep it in a clean container — we may be able to re-cement it!
  • If pieces are broken or sharp, take extra care not to bite down on that side.
  • Try not to irritate your tongue by playing with it or checking it out. Good luck with that!

If you feel any sharp edges, you can try protecting your cheek or tongue by placing a small piece of chewed sugar-free gum or dental wax over the area.

3. Manage Pain and Sensitivity

A lost crown can expose the sensitive part of your tooth. To ease discomfort:

  • Take over-the-counter pain relief as directed
  • Avoid very hot, cold, or sugary foods
  • Stick with soft foods
  • An old school method that works is to apply oil of cloves to the exposed area. It has a moderate numbing effect.

If sensitivity is mild, chewed sugar-free gum placed over the tooth can help temporarily seal it.

4. Try Denture Adhesive

Most any denture adhesive paste or gel will temporarily hold a crown in place as long as there is enough structure remaining.

Clean any loose material and food out of the crown.

Try the crown on to make sure you know which way it fits.

Fill the crown about half way with adhesive and place it back in. Press with your finger to make sure it seats solidly. The excess adhesive should squeeze out and can be wiped off. Gently bite to verify it is seated correctly.

Remember this is a temporary fix and be vigilant when eating so it doesn’t come off and you bite it, breaking it or one of your other teeth.

If you are concerned about it coming off in your sleep we recommend you take it out and put it in a safe location away from pets (they will be attracted to it and would love to eat it) while you sleep then put it back in the morning.

5.  Chewed sugarless gum or gel toothpaste.

If you don’t have denture adhesive you can try the same technique with chewed sugarless gum (it will take very little inside the crown to hold it) or gel toothpaste, it’s not as sticky but will often create a seal that will hold it in place fairly well.

Store bought temporary dental cement is typically much too thick to use to cement a crown

Filling out or a broken tooth with a hole.

Make sure the hole is cleaned out well; rinsing, brushing, and irrigating all work well. You are very unlikely to cause any further damage with any of these and making sure the area is clean will help slow the destruction.

Dental wax, chewed sugarless gum, and store bought filling material are reasonable options to place in the hole. Be careful not to push too hard and cause discomfort on the gums and be careful when biting as you may push it in further.

These are NOT permanent fixes — they are temporary solutions only. You still need to see your dentist as soon as possible.

5. What Not to Do

Avoid:

  • Using super glue, or household adhesives to fill the gap
  • Chewing on hard foods or ice on the affected side
  • Ignoring persistent pain or swelling

These can worsen the problem or damage surrounding structures.

Why Prompt Dental Care Matters

A lost filling or crown doesn’t always hurt at first — but the risk of infection, decay, and structural damage increases over time. At Oroville Gentle Dentistry, we take your comfort seriously and provide:

Delaying care can turn a simple fix into a major procedure like a root canal or extraction — and we want to help you avoid that.

When to Call the Dentist Right Away

Seek immediate care if you notice:

  • Severe pain that doesn’t go away
  • Swelling of gums or face
  • Painful tooth associated with the area feeling hot to the touch or a systemic fever or signs of infection
  • Anything lodged in your gum

These can indicate a more serious problem requiring urgent treatment.
