Benzocaine spray is often used to numb the membranes of the mouth. It can be used prior to dental or medical procedures, or to relieve the pain of sore gums or throats. The pain and itching associated with hemorrhoids and sunburns can also be relieved with benzocaine spray. Some people also use this type of numbing spray prior to hair removal procedures, such as waxing.
Benzocaine is primarily used as a pain reliever. It is an anesthetic that works by blocking the nerve endings near the skin's surface. When these nerve endings are blocked, a person can't feel any sensations on the skin, including pain.
This type of anesthetic spray is often used in the mouth. Some dentists use benzocaine spray to numb an area of a patient's mouth before a minor dental procedure. It may also be used to help ease the discomfort of new dentures, but it should not be used as a long-term solution for ill-fitting dentures. Doctors might also use benzocaine spray to numb a patient's throat prior to inserting or removing a tracheal tube, or breathing tube.
Individuals can also purchase over-the-counter benzocaine spray. These types of anesthetic sprays can be used to relieve pain due to minor mouth sores, such as canker sores. Some sore throat sprays may also contain benzocaine. Spraying the back of the throat with these types of sprays can lubricate the area as well as numb it, which can make dealing with a sore throat much more comfortable.
Hemorrhoids occur when small blood vessels in the anus or rectum become inflamed and bulge. This can be a very painful and uncomfortable condition. A variety of products help treat hemorrhoid symptoms, including hemorrhoid sprays. Some hemorrhoid sprays contain benzocaine, which can help relieve the pain and itching associated with this condition.
Benzocaine spray may also be sold as a product to help relieve the pain of burns. Sunburn sprays, for instance, can often be used to minimize the discomfort of burned skin due to prolonged sun exposure. Many of these sprays can also be used to help relieve discomfort caused by insect bites and poison ivy. These types of sprays also usually contain a soothing compound to promote healing, such as aloe vera.
Some hair removal procedures can be somewhat painful. Salons often use a numbing spray, such as benzocaine spray, prior to waxing. Some home waxing kits also contain small bottles of benzocaine spray.
