Local anesthesia is a technique to coax the absence of sensation in a specific part of the human body, generally for the aim of inducing local analgesia, that is, local insensitivity to pain, although other local senses may be affected as well.

  • Injection

In case of topical anesthetics: These are applied directly to your skin or mucus membranes, such as the inside of your mouth, nose, or throat. They can also be applied to the exterior of your eye. Topical anesthetics come in the form of gels, liquid, creams, sprays and patches.

In case of Injection: Local anesthetics can also be given as an injection. Inject able anesthetics are typically used for numbing during operations, rather than pain management.

Your consultant will determine the best type for you based on several factors, including: the length of operation, if you take any kind of medicines, any type of underlying health conditions you have and the size and location of the particular area that  needs numbing.

What are the side effects of anesthesia?

In case of local anesthetics are generally safe and usually don’t cause any kind of side effects, aside from some tingling as it comes off. However, if you’re given too much, or the injection goes into a vein instead of tissue, you might have many side effects, such as: numbness, dizziness, ringing in ears or a metallic taste in mouth.

Local anesthesia is a relatively safe way to numb a small area before a operation. It can also help to manage pain on your skin or in your mouth. While it can occasionally cause side effects, this usually only happens in cases that involve doses above the recommended amount.
