I found orajel that expired in 2005, is it safe to use, will it just work less or will it be dangerous to my mouth?

Oragel: Oraljel that has been expired for 15 years! When in doubt throw it out !

Way too old...: That poor old tube of Orajel is waaay past its prime. It probably isn't worth the effort to use it. Go spring for a new tube or container of a similar product and then you'll get more years from it, let alone immediate relief.

Oragel: Not dangerous, but after 15 years, not effective. Throw it out and buy new.

Dated med: Rule of thumb, meds May be therapeutic for about a year beyond expiration date. Toss it and buy a new tube.

May not help: For almost all drugs, the expiration date reflects how long a drug has been studied and determined to still be potent. The product’s effectiveness may decrease once it goes past its expiration date. In a handful of drugs, toxic chemicals may form after the expiration date. As for Orajel in question, just understand that it may not work. If you can afford to purchase a new tube, that would be best.
