The one medication almost certainly to be used is a local anesthetic, there're numerous types and why they may use them. If they're using medication to relax you is another matter, same as before. The reasons and type is dependent on many issues.
We usually use lidocaine with epinephrine, but to some, we have to use carbocaine, which does not have epinephrine and patients who are allergic to other types of local anesthesia.
He might use topical anesthesia first, and he will use a local anesthetic.
The usual medication is a local anesthesia like lidocaine 2% or septocaine 4%
There are many different medications they may use. It may be lidocaine or septocaine or something else. Ask you doctor. They can answer that for you. If it doesn't suit you, they will choose a different medication.
Lidocaine and carbocaine are very common local anesthetics and can be combined with epinephrine in various concentrations.
There are different local anesthesia that dentists may use
Typically, we use Lidocaine and may supplement with an anesthetic called Septocaine. These anesthetics are very well tolerated by most people. Your dentist will discuss your prior medical history, as well as, any known drug allergies. Don’t worry. You should be just fine.
The choice wil be determined on your needs, and general health state. I am sure that your doctor will choose wisely, and if you have questions, don’t be afraid to ask.
There are several formulations of a 'Novacaine' like drug: Carbocaine, Mepivacaine, Prilocaine, Septocaine...as far as I know, these rarely cause any adverse reactions.
The local anesthetic to be used will likely be Lidocaine or its equivalent in the recommended dose. Prior, check for any allergic reactions which are rare.
The endodontist or dentist will probably start with a topical anesthetic before giving you an injection of local anesthesia which probably will be one or two of the following types depending on your individual needs and where the procedure is located. 1. Lidocaine 2. Septicaine 3. Prilocaine or 4. Carbocaine.
Good luck!
Typically, dentists will use either lidocaine or septocaine for local anesthetic to do a root canal treatment. If you are asking about the anesthesia for sedation it could be something else entirely, but that is rare for a simple root canal. There are other types of anesthestics that can be used if you have certain medical risks. Your dentist should be able to discuss all the alternatives with you and answer all your questions.
Several different medications can be used for anesthesia. The most common brands used are Lidocaine or Septocaine. Lidocaine and Septocaine are used with epinephrine to prolong the effect of the anesthesia. Carbocaine is another anesthetic commonly used that does not contain epinephrine, which decreases the time of which the anesthetic will have its effect. Lastly, depending on the situation, nitrous oxide sedation may be used. All of these depend on the severity of the infection, the location of the tooth, and the patients health history. If the medicine does not suit you the most likely complications are anxiety attacks and possible heart palpitations. However, heart palpitations are unlikely.
The doctor will use whatever anesthetic is best for you and the root canal. He has a number of choices. There is no one anesthetic that all dentists use for all root canals. He will actually probably use more than one kind.
Most of the time, 2% lidocaine with 1:100k epinephrine is used as anesthesia for routine dental procedures, including root canals. There are other types of anesthetics and most are in the class of medications known as amides, which most people have no problem with. Some are combination of esthers and amides. Most of the time, the anesthesia is administered locally, so you are awake the entire time, just numb in the area to be worked on. Your provider knows which anesthesia he/she likes to use and can review that with you if you are concerned.
I hope this answer to your question finds you in time as I'm not used to working under a deadline. There are multitude of anesthetics that are commonly used by both dentist and specialist in root canals called endodontist. You can be assured that by the time you are medicated or pre-medicated in some cases your medical history will have been checked to rule out any allergies of local anesthetics. Which these are statistically low incidence of sensitivity for allergies. Reactions to a local anaesthetic are statistically very low. They are also a multitude of onsets and durations to customize the estimated length of time your procedure will take and depending on whether they are Esters or amides they fall into categories of different effects. Your dentist will possibly offer you a pre sedative to relax you prior to visit, and possibly nitrous oxide which is an inhalation agent used to suppress anxiety prior to the administration of a local anesthetic to actually numb the area around the surgical site. Since some bone may be removed as you specified endo-surgery a vasoconstrictor will be part of the medication in order to control hemorrhaging. Your procedure May last 30 minutes or it may last an hour so the selection of the anaesthetic will determine the effect that it gives based on clinical judgement of your doctor. Also compresses maybe recommended in order to control edema. Relax and be fully confident that you'll be as comfortable as possible in this tedious surgery to save your tooth from further infection.
Most dentists use the latest local anesthetic, such as Lidocaine. If your dentist uses analgesia (gas), ask if that is available.
There are a number of anesthetics that a dentist can choose from to anesthetize your tooth. Every one of them should suit you. If you are concerned about the treatment, discuss it with the dentist.
Typically, a local anesthetic such as articaine (very popularly used by a multitude of dentists). Depending on the status of the nerve, that may be sufficient. The chemistry of an infection competes with that of the anesthetic. So supplemental LA may be needed: PDL which means in the ligament that surrounds each tooth; or into the nerve itself.
Anesthesia pretty much works on every patient unless there is infection, at such time, the doctor may put you on antibiotics. I wouldn't be concerned about the anesthesia, it should work fine regardless of what the doctor uses.

Unless the tooth is infected, probably no medication other than local anesthetic to numb you. After the procedure, the dentist may prescribe an antibiotic and a pain killer. Sometimes, but rarely, a steroid may be prescribed. Your dentist will take a thorough health history to determine what medications will be suitable for you.
The most common local anesthetic is lidocaine 2%, therefore each carpule contains 34 mg of the drug lidocaine and .017 mg epinephrine, which is a vasoconstrictor. HCl is also in the carpule, as a preservative to increase shelf life.

It’s the same as for a filling.
The most common anesthetic is lidocaine with epinephrine. There are other types of "caines" if the licocaine is ineffective. Also, there may be other anesthetic techniques the dentist may use for effective anesthesia. Just let the doctor know what you are feeling.
The type of anesthesia used for root canal therapy or surgery depends on the specific patient. Your dental professional should review your health history and choose an anesthetic that would be amenable to your specific situation.

Hey there! Dental local anaesthetics (e.g. lignocaine, mepivacaine, articaine) are among the most researched, safest and most widely used drugs in the world. The likelihood of allergic reaction or complication because of this drug is minimal to none.

When you think about it, the alternative is to leave pus-forming bacteria inside your jawbone... I'd take the anaesthetic and root canal procedure every day of the week!

All the best, hope it works out really well!

The most common type of local anesthesia the dentist will use is Lidocaine with epinephrine. Most dentists today do not use "Novacaine" and have not since the 1950s due to a higher incidence of allergic reactions. This is why dentists have switched to other local anesthetics. Most anesthetic makers do put some type of preservative in the solution. The type varies from manufacturer, but it is very rare that someone will be allergic to it. The most common "reaction" that people feel to the anesthetic is that their heart may race for a few minutes. This is because some people are more sensitive to the epinephrine (also called Adrenalin) and not the anesthetic itself. The epinephrine is included in with the anesthetic to help constrict the blood vessels in the area to help keep the anesthetic in the area longer. If the medicine does not suit you, there are several other types of local anesthetics that most dentists keep in the office. Finding one that suits you is rarely ever a problem.
