Sometimes during a dental operation, your dentist may need to numb some parts of your mouth by injecting local anesthesia into your inner cheek or gums. While dentistry and pain are synonymous in the minds of most dental patients, the local anesthesia at Dental Wellness clinic in Kellyville has benefited them and most of their patients by enabling them to make advances that would have not happened. One of the most common local anesthesia is lidocaine.

However, the numbing medicine is only part of what’s injected. The liquid in the drug also contains;

•Sodium hydroxide that helps the drug to work
•Vasoconstrictor which is a drug that not only narrows the blood vessels but also makes the numbness to last longer.
•Sodium chloride which makes the drugs to get into your blood well.
•A special chemical that prevents the vasoconstrictor from breaking down.

Types of local anesthesia dentistry

There are two types of local anesthesia. An infiltration drug that only numbs the area where the operation will be done and a block injection that numbs the entire part of your mouth. Depending on the type of drug used, local anesthesia can last for up to 7 hours.

Preparation

If you are going to have dental surgery, that involves the use of local anesthesia, the doctor should explain to you how to prepare. However, you must inform the doctor about other medications that you are using especially if you are using thinning agents such as warfarin and aspirin. Once you are in the dentist office, he will apply the local anesthetic agent to the relevant areas of the mouth. If you do not feel the numbing effect the dentist will not proceed with the procedure. While the drug will prevent you from feeling any pain, you may still feel some pressure during the operation.

Side effects

Since local anesthetics are the most common drugs being used, they have very few side effects. One possible effect is a hematoma which can be described as a blood-filled swelling that can form when the needle hits one of the blood vessels. The medicine may also cause numbness to non-targeted areas. In addition, the needle being used may injure a nerve leading to pain and numbness for several months.

It’s therefore important that anyone administering local anesthesia dentistry is fully trained and qualified.
