Understanding Anesthesia: The Basics from Your Hamilton Dental Clinic

Here is what you should know about anesthesia before you undergo a dental procedure in Stoney Creek:



  • What is it?: Anesthesia is a combination of liquid medicines that contribute to freezing and limit discomfort during dental procedures. These are typically injected as a combination of numbing drugs, vasoconstrictors that narrow blood vessels and extend the numbness period, sodium hydroxide that increases the efficacy of numbing drugs, and sodium chloride that speeds up the process of getting the drugs into your bloodstream. 
  • How is it administered?: Local anesthesia will usually be done through a combination of techniques. A topical gel may be used to numb the area before a needle is used for the numbing injection. 
  • What kinds are there?: Two types may be used. The first is a block injection that has a larger impact by numbing an entire area of your mouth, such as the upper jaw. An infiltration injection is the second, which is appropriate when a smaller location needs attention.
  • How can I prepare?Your dentist will give you instructions to prepare you for your appointment. In some cases, you may be asked to refrain from eating and drinking before treatment.
  • What are common side effects?: Some people face allergic reactions. Any allergies should be discussed with your Hamilton dentist at your initial consultation, along with any other concerns about anesthesia or dental care. In rare cases, some individuals experience a blood-filled swelling called a hematoma, increased heart rate, or injured nerves at the injection site. Sometimes patients experience numbness beyond the target area, which can lead to trouble blinking or drooping in the eyelids and mouth until the drugs wear off.

Common Dental Treatments that May Require Anesthesia

Each case is individual, and your Hamilton family dentist will be able to provide information about your particular dental appointment. However, these are some typical dentistry procedures that may involve dental freezing or local anesthesia:
