Many drugstores and pharmacies sell denture repair kits, an emergency-only liquid and powder combination that you can mix together to form a glue. This glue can temporarily mend cracks and breaks until you can get in to see your dentist.
Types of Denture Breaks
Dentures are made to be durable, but there are four ways they commonly break.
- A tooth comes off or breaks.
- The acrylic plate of the denture breaks in half.
- A piece of the pink acrylic plate breaks off.
- If you have a partial denture, the metal clasp can come loose or break.
Dental repair kits are sold to mend the first three problems on a temporary basis.
Repairs You Can Make
While denture repair kits can work well for replacing teeth that may come out, most denture professionals don’t recommend using them for a break in the denture. That’s because the denture will only work well if it has been adhered together absolutely perfectly. If you don’t manage to match up the pieces exactly, there will be a ridge that can be uncomfortable, keep your bite from being aligned correctly or prevent it from staying in properly. Plus, the denture will almost certainly come apart or break again, possibly in a different spot near the original crack.
If you use a denture repair kit and form an adhesive seal to temporarily fix the main plate, it may not be possible to get it apart again for a professional to make an exact fix. That means you’ll be purchasing new dentures, where if you had not used the kit, your dentist could have made a long-lasting repair.
How the Kits Work
Denture repair kits work by forming a waterproof adhesive that is nontoxic and can bind the acrylic pieces in your dentures back together.
Each kit contains powder and liquid in separate packets. You empty a packet of the powder into an included mixing cup, then follow the manufacturer’s directions for how much liquid to add. This liquid can be harmful to your skin, so wear gloves or be very careful not to come into contact with it.
The mixed adhesive can have a strong odor, so use it in a well-ventilated area. It should have the consistency of syrup.
Use the included wooden tool to apply a thin layer of the adhesive to both surfaces of the broken denture. Put them together and hold for 5 minutes or as long as the instructions state. Once the adhesive has set, you can scrape off any excess adhesive.
Depending on the type of kit you have, you may need to soak the dentures in water or let them sit for a set period of time. You may also need to sand the repaired area lightly to make it smooth.
When Not to Use Denture Repair Kits
You should use these kits only on acrylic dentures. If you have a flexible denture, the kits will not work.
Also, do not try to use the denture kits to mend caps or crowns. They are for use on removable dentures only.
How Long to Use the Repaired Denture
Because the adhesive used in denture repair kits is fairly strong, the repair should last a few days until you can make it into your dentist.
Don’t be tempted to use the denture kits to make a permanent fix. They are not designed to be long lasting and your denture is likely to break again. Your dentist can use a much stronger acrylic bonding product to make a permanent repair.
Another reason why you should visit your dentist right away if your denture breaks is that you may have had some change to your mouth or to the fit of the denture that resulted in the initial break. A dentist (such as one from Boviz Denture Clinic Services) can assess your mouth and determine if you need a new denture or if there are any other issues with your mouth or oral health.
