My Temporary Crown on the Back Tooth Came Off- Do I Need To Cement Temporarily Until Dentist Visit?

Temporary crowns can come off the best thing to do is to place the temporary crown back on the tooth. Sometimes it will hold good enough till you see your dentist and avoid hot and cold foods. If due to lack of retention, you can get dental cement from pharmacy and place a little amount inside the crown and place it back on and follow the directions. You always want to put the crown back in your mouth so teeth do not shift and your teeth are not sensitive.

Visit the nearest dentist in a day or two to get the temporary crown fixed with a temporary cement. I will not suggest Self cementation using over the counter dental cements. Delaying too much will cause migration of adjacent teeth and supra eruption of opposing teeth and the impression measurements will not match with the teeth position in the mouth. Thereby outcome of the treatment will not be good.
During the day time , if it permits , you can place the crown on the tooth yourself without cement and remove it during consumption of food. Also remove during sleep. This will prevent movement of adjacent teeth to a great extent till you see a dentist in 2 days time.

Hi,
I would suggest gluing it back in so that you can eat properly without pain.  Usually when crowns come off they can be easily recemented by removing the excess cement and using some conventional dental cement (these can be found at drug stores in the dental aisle) until you get to see your doctor in a few days.  Hope you feel better!

Call your dentist and get in to recement the temporary as soon as possible. Until then, place some Fixodent in the crown and put it back on yourself. Wipe away the excess. You need to keep it covered so it does not become sensitive and is not exposed. Also, the tooth can drift slightly and the tissue may overgrow if it is uncovered for too long.

If your temporary crown falls off or breaks while you're waiting for your final crown to be delivered, first, I recommend you call your dentist's office. If they are closed, leave a message. If the crown is still in tact and you're able to figure out how it fits back on the tooth, you can actually buy over the counter temporary cement and put it back on yourself. I would recommend to clean the inside of the crown as best you can, put a small amount of the temporary cement inside the crown and push it back on the tooth with firm pressure. Then, make sure to try to remove the excess temporary cement that extrudes out (with a toothpick or something similar, but don't try too hard to push around it or it may come off again). Teeth can shift in as little as 24-28 hours so it is important to have the temporary crown hold it in place so your final crown will fit.

Although significant drifting of your tooth is unlikely to occur in 2 days, you should just put it back on. If you can't find any temp cement then a little bit of toothpaste inside the temporary is a little trick that can hold it in place for a short amount of time. Avoid sticky stuff and go see your dentist asap. 

If you're not in any pain and your tooth isn't sensitive, it's probably fine to leave it alone for two days - just be extra careful. You shouldn't leave it for more than two days, though. If you'd rather be on the safe side, you can get some temporary dental cement and put it back on yourself until you can see your dentist. Make sure to test out the position of the crown before putting the cement in to make sure it fits back in properly. 

Hi:It’s always best to have the temporary tooth recemented to avoid any tooth movement that may interfere with cemenatation of the final crown.Best,Dr. Maddahi

Try to get an appointment with your dentist as soon as possible. Some store emergency cement kits have a chemical called eugenol in them. If your dentist was planning to attach your permanent crown with a resin based adhesive for a good bond, then eugenol can significantly reduce the adhesion of the final crown to the tooth. 
Call your dentist before sticking something in, as in the worst case s/he will not be able to fit it on the next visit until the eugenol has worn off.

Good luck and kind regards

Temporary crowns do come out on occasion. Ideally it should be placed back on the tooth right away, because teeth shift. Without having it on, teeth might move and create a situation, where is NOT enough space for a permanent crown to fit well. At best it will take a longer appointment to deliver a permanent crown.
