How to glue a dental crown back on?

Losing a dental crown can be an incredibly jarring experience. Whether it happens while you are eating something sticky, brushing your teeth, or simply out of nowhere, you are suddenly left with an exposed, sensitive tooth structure and a loose restoration. If you are unable to see a professional immediately, knowing how to glue a dental crown back on temporarily can protect your tooth from damage and ease discomfort.

However, it is vital to emphasize right from the start that any self-applied method is strictly a temporary fix. Permanent cementation requires commercial-grade materials, absolute moisture control, and professional expertise to avoid complications like trapping bacteria or misaligning your bite.

The Step-by-Step Guide: How to Glue a Dental Crown Back On

If you are stuck in a situation where dental care is not immediately accessible, follow these steps to secure the crown temporarily using safe, over-the-counter materials.

Step 1: Examine the Tooth and the Crown

Before attempting anything, look at the crown and the underlying tooth. If the tooth structure inside the crown has completely fractured off or the crown itself is broken, do not try to put it back. If the crown is completely hollow and intact, and the remaining stub of your natural tooth is clean and solid, you can proceed.

Step 2: Clean the Crown and the Tooth

The key to getting any temporary adhesive to hold is cleanliness.

• Use a toothbrush and a little bit of toothpaste to gently clean out any old, crusty dental cement remaining inside the crown.

• Carefully rinse the crown and let it dry.

• Gently brush or rinse your exposed natural tooth to ensure no food particles are trapped.

Step 3: Test Fit the Crown

Never apply adhesive without testing the fit first. Place the dry crown over your tooth to see exactly how it aligns. Bite down very gently. If it feels too high, tilted, or unnatural, remove it and try adjusting its position. If you glue it on crooked, you risk fracturing the underlying tooth structure when you chew.

Step 4: Choose a Safe Temporary Adhesive

You must use a safe product meant for oral use.

• Over-the-Counter Temporary Dental Cement: Brands found at local pharmacies are specifically designed for this exact dental emergency.

• Temporary Denture Adhesive: This is a safe alternative that provides a weaker hold but is incredibly easy to clean off once you get to the dentist.

• What to Avoid: Never, under any circumstances, use industrial superglue, gorilla glue, or household craft adhesives. These chemicals are highly toxic, can kill the nerve of your tooth, and will permanently destroy both your crown and the remaining tooth structure.

Step 5: Mix and Apply the Material

If you are using temporary dental cement, follow the mixing instructions on the packet. Place a very small amount of the material inside the hollow cap of the crown. You only need enough to lightly coat the inner walls. Overfilling it will prevent the crown from seating properly.

Step 6: Seat the Crown and Bite Down

Align the crown properly over your tooth and push it down firmly with your finger. Once it is mostly in place, place a piece of gauze or a cotton roll over the crown and bite down with even, gentle pressure to squeeze out any excess material. Keep your jaw closed for a few minutes until the temporary cement begins to set.

Step 7: Clean Up Excess Cement

Once the material has firmly set, use a toothpick or a toothbrush to gently scrape away any excess cement that squeezed out around your gum line. Leaving excess material behind can severely irritate your gums.

When to See a Professional

This home remedy is only a stopgap measure designed to last a few days at most. You must schedule an appointment with a professional clinic to ensure the health of your tooth. For instance, global dental providers like the renowned Vitrin Clinic specialize in restorative dentistry.

At a professional facility like Vitrin Clinic, the average cost of a brand-new, premium dental crown typically ranges from $200 to $450, depending on whether you choose high-quality materials like Zirconia or E-max porcelain. If your old crown is completely healthy, a dentist will simply clean it professionally and secure it with permanent, durable dental resin at a much lower cost. Leaving a temporary home fix in your mouth for too long will inevitably cause saliva to leak underneath, inviting rapid tooth decay, pain, and eventual tooth loss.
