is autoclaving same as heating the tooth?

in general autoclaving is indeed heating

Specifically, autoclaving is a method for sterilizing equipment under pressure at 121 degrees C for 15-20 minutes. You can Google "autoclaving" for more information. I have seen this done by dentists for natural teeth that are to be re-inserted as part of the dental procedure but I don't know if it is safe for dentures.

No, autoclaving is not the same as heating a tooth. Autoclaving is a process used to sterilize equipment, including dental instruments, by subjecting them to high-pressure saturated steam at a high temperature. This method effectively kills bacteria, viruses, and other microorganisms that may be present on the instrument's surface.

On the other hand, heating a tooth refers to the application of heat to a tooth during certain dental procedures. Dentists may use heat for various purposes, such as reshaping dental materials or curing dental fillings. Heat can also be used in endodontic treatments like root canal therapy to help soften dental materials for easier manipulation and filling of the root canal system.

So, while both processes involve applying heat, autoclaving focuses on sterilizing equipment, whereas heating a tooth is a dental treatment technique that serves different purposes.
