A dental crown popping off is never convenient, but it happens - usually right before an important event or on a weekend when your dentist’s office is closed. The exposed tooth stub can be sensitive, and leaving the crown off too long risks the tooth shifting or the stub becoming damaged. Temporary dental crown repair cements are OTC products that let you re-seat the crown safely at home while you wait for a professional re-cementation. In 2026, there are several reliable options available on Amazon. Here are the five best.

1. Dentemp Maximum Strength One Step
Dentemp is the most recognized name in OTC dental repair and their Maximum Strength formula is the top choice for re-cementing loose crowns. The putty-like cement is applied inside the crown, the crown is placed over the tooth, and you bite down to seat it. It sets in about 60 seconds and can be chewed on lightly within a few hours. The formula is strong enough to hold for 1-3 weeks in most cases. It’s also pharmacist-recommended and widely available at CVS, Walgreens, and Amazon.
Pros: Strong hold; fast set; easy to apply; widely trusted; available everywhere. Cons: Can be tricky to apply perfectly without dental training; temporary only.
2. Recapit Crown and Cap Cement
Recapit is another highly rated OTC crown cement that comes in a small tube with a precision tip for easier application inside the crown cavity. The zinc oxide-based formula bonds firmly and has a slightly longer working time than Dentemp, giving you a few extra seconds to position the crown correctly before it sets. Users report it holding reliably for 1-4 weeks. The kit includes a small spatula and mixing instructions, making it slightly more user-friendly for first-timers.
Pros: Precision tip applicator; longer working time; reliable hold; easy instructions. Cons: Slightly more expensive per use; tube packaging can clog if not stored properly.
3. DenTek Temparin Max Lost Filling and Loose Cap Repair
DenTek’s Temparin Max is a versatile repair kit that handles both lost fillings and loose crowns in one product. The formula is slightly softer than Dentemp, making it easier to shape around a filling cavity, but it works well for re-seating crowns too. The set includes enough material for multiple applications, which is useful if you need to reapply or if you’re traveling. It’s a good all-in-one kit to keep in a medicine cabinet for dental emergencies.
Pros: Handles both crowns and fillings; multiple-use kit; easy to work with. Cons: Slightly softer hold than dedicated crown cements; shorter hold duration for heavy chewing.
4. Urgent RX Aching Tooth Gum Formula
This product combines a soothing topical analgesic with temporary dental cement, making it useful when a loose or dislodged crown comes with tooth sensitivity or mild pain. The gum-based formula is applied around the crown margins and provides temporary pain relief while sealing the crown. It’s not as strong a structural cement as Dentemp or Recapit, but the pain-relief component makes it valuable for patients with significant sensitivity after crown displacement.
Pros: Pain relief + sealing in one product; soothing formula; good for sensitive teeth. Cons: Weaker structural hold than dedicated cements; better as a stop-gap for pain than as a firm re-cement.
5. OraCare Dental Cement Temporary Formula
OraCare’s temporary dental cement uses a zinc oxide eugenol (ZOE) base - the same chemistry used in professional dental offices for temporary cementation. This gives it a more clinically familiar feel and good antimicrobial properties that help protect the exposed tooth stub. The eugenol component has a mild anesthetic effect, which reduces sensitivity. The downside is that eugenol can interfere with some permanent cements, so be sure to tell your dentist which product you used.
Pros: ZOE formula mirrors professional temporary cement; mild anesthetic effect; antimicrobial. Cons: Eugenol may interfere with some permanent dental cements; stronger taste; less widely stocked.
What to Look For
Hold strength - For active chewers or those who will be waiting more than a few days, choose a maximum-strength formula like Dentemp or Recapit over softer combo kits.
Application method - Precision tips and single-application packs are easier to use correctly than bulk tubes.
Sensitivity relief - If the exposed tooth is painful, choose a formula with eugenol or topical anesthetic.
Number of applications - Single-use packs are hygienic but multi-use tubes offer better value if you need to reapply.
Dentist notification - Always inform your dentist which product you used, especially if it contains eugenol, as this affects the final re-cementation process.
Final Thoughts
Dentemp Maximum Strength earns the top spot for its reliable hold, ease of use, and wide availability. For a slightly more clinical approach, OraCare’s ZOE formula mirrors professional temporary cements. In all cases, these products are temporary bridges - schedule a dentist appointment as quickly as possible. A crown that keeps coming loose often signals a fit issue or decay beneath the crown that needs professional evaluation before permanent re-cementation.
Frequently asked questions
Is it safe to re-cement a dental crown at home?+
Temporary re-cementing is safe as a short-term measure. These products are designed to hold a crown in place for days to weeks while you arrange a dentist appointment. They are not a permanent replacement for professional dental cement.
How long does dental crown repair cement last?+
Most over-the-counter crown cements hold for 1-4 weeks depending on the product, chewing habits, and how well the original crown fits. Dentemp and Recapit can sometimes last longer, but a dentist visit is always recommended within a few days.
What should I do before applying crown repair cement?+
Clean the inside of the crown and the tooth stub thoroughly, dry both surfaces completely, and follow the product instructions carefully. Never use super glue - it bonds permanently and can damage the tooth structure.
