Converting 740 torr to mm Hg: 1 torr = 1 mm Hg so 740 torr = 740 mm Hg
Total pressure = partial pressure O2 + partial pressure N2O (nitrous oxide, not nitrogen oxide)
Pressure of N2O = 740 mm Hg - 370 mm Hg = 370 mm Hg
To take out a molar, a dentist will first numb the area with a local anesthetic. They will then use special tools to loosen the tooth from the socket and carefully extract it. In some cases, stitches may be needed to close the extraction site.
William Morton, a dentist, is credited with first publicly demonstrating the use of ether as an anesthetic in 1846. Charles Jackson, a physician and chemist, claimed to have suggested the use of ether to Morton.
You have to go to a dentist to find out
you take it to a dentist
fermantion is different by the dentist
1) When I had surgery on me teeth the dentist used the anesthetic, so their wasn't pain.
an anesthetic is a drug that numbs your sensation and sometimes dampens your alertness. There are many types of anesthetic including topical (benzocaine cream for example), local (a novacaine injection at the dentist for example) and general (which is what they would use to "knock you out" for a major surgery)

Yeah, kind of . Pinching . Ask the dentist for a topical anesthetic.
If the dentist plans to cut, yes, he will numb you. Braces can be painful at first but don't usually require anesthetic.
The options include oral medication to help with anxiety, an injectable anesthetic to numb the area (and a good bit of your face), nitrous oxide (Inhalation Sedation) to alleviate pain, or general anesthesia in which you are completely knocked out for the procedure. Not all dentists offer all options. Many of the options can be used in concert with one another (oral medication, nitrous and injected anesthetic, for example). The available options depend on what your dentist offers and what the two of you decide is the best plan for you.
The first recorded use of ether as an anesthetic agent in surgery is attributed to dentist William T. G. Morton, who successfully demonstrated its use during a tooth extraction in 1846 at the Massachusetts General Hospital in Boston.
Generally speaking, tooth extractions do not require a hospital visit, they can be done at your dentist's office. There may be exceptions for people who are allergic to the anesthetic the dentist uses or if the patient has an underlying health condition which may make an extraction in a hospital setting a safer alternative.
I'm going to be honest... yes.Another View: If you have a 'good' doctor or dentist, they will numb the place where you will receive the novacaine shot with a topical anesthetic which they will apply with a cotton swab first.
The job description of an expanded functions dental assistant varies dentist to dentist and state to state. Some duties may include coronal polish, sealants, topical fluoride, and topical anesthetic which are not normally performed by dental assistants.
Root canals can and are done without anesthetic if a tooth is known to be dead. This can usually be determined *before* the root canal is started. To answer your question, if a tooth is dead and asymptomatic, you may be able to have the procedure without anesthetic but the main reason would be to avoid having a shot and hours of numbness, rather than to "see if you feel pain." I would see an endodontic specialist if possible. It could be, but never let a dentist do a root canal without anesthetic, even if the nerve is removed there is still tissue there which feels pain. I know, I had it done by a dental student. She thought that because the nerve was removed (the week before) I wouldn't feel pain, and her supervisor thought she had given me a local anesthetic.
