I would not do it yourself for a number of reasons. You may think you are saving $85 in the short term but may be doing damage that will cost you alot more in the long term. Do yourself a favor and don't play dentist. Let the professionals do their job.
1. dental cements are not "glue". Glue is toxic.
2. Crowns come off for a reason. It is likely there is something wrong with the tooth underneath.
Why are you being charged to reset it? I've had a couple pop off before and my dentist never charged me to reset it. He considered that part of the cost I originally paid for what was supposed to be a permanently cemented crown.
