Dentists use pain control products to control pain and discomfort their procedures may cause. The best way to achieve pain control is with the traditional use of local anesthetics. A local anesthetic is a substance that is injected to a specific area inside the mouth to cause a reversible loss of sensation. This means that after a certain amount of time, the numbing goes away. Each anesthetic drug does the same thing – they all “numb”. However there are different anesthetic drugs in the dental market that can be used on patients. This is a decision that the dentist will make based on the age, weight and medical history of the patient.

There are 5 different types of anesthetics that are available in the dental market, but only one that is designed and used strictly for dentistry – Ultracaine®. Ultracaine® is a brand of anesthetic drug that is available to dentists across Canada and is known as a very profound anesthetic. Ultracaine® is clinically proven effective by proving anesthetic success in routine dental procedures. Ultracaine® is a rapidly growing anesthetic in the dental market, and with 30+ years of experience, there have been zero recalls on the solution!

About Ultracaine® 

Ultracaine® History

Ultracaine® is the original Articaine, one of the main local anesthetic drugs used in dentistry. It was designed specifically for dentistry and was developed in the late 1970’s by a German company, which is now a part of Sanofi – one of the largest pharmaceutical companies in the world. Ultracaine®was launched in Canada in 1983, while the distribution was taken over by HANSAmed in 1999. Presently, we are still the sole distributor of Ultracaine® worldwide!

Ultracaine® Manufacturing

Each individual Ultracaine® cartridge is manufactured aseptically and is latex-free. Ultracaine® is the only anesthetic that is packaged in a unique environmentally-friendly, all-cardboard packaging that is easy to recycle. Ultracaine® is manufactured with two epinephrine concentrations: Ultracaine® DS and Ultracaine®DS-Forte. The only difference between Ultracaine® DS and Ultracaine® DS-Forte is how long the numbing will last.  Ultracaine® DS-Forte is known as “the surgeons anesthetic” because it lasts longer than Ultracaine®DS.


Ultracaine®4% (articaine hydrochloride with epinephrine) is indicated for infiltration anesthesia and nerve block anesthesia in clinical dentistry.

How the patient will benefit from Ultracaine® 

As a patient seeking dental treatment, you are hoping to be treated with the most premium dental products on the market to ensure success and safety. Ultracaine® has unique properties that are different than any other local anesthetic drug available. The chemical structure of Ultracaine® gives the medication a quick onset (the time it takes for the medication to work) of 1-3 minutes. This ensures the patient is comfortable right from the start of the treatment until the end. Ultracaine® also has additional safety properties. The way the medication is broken down in the body naturally reduces the risk of toxicity and overdose. This happens because Ultracaine® has the shortest half-life (the time it takes for half of the medication to be metabolized) of 27 minutes.
As a patient, you have a right to know which materials are being used in your mouth at each procedure – including dental anesthetics. Ask your dentist about Ultracaine®, a clinically proven effective anesthetic drug.
