Exploring Modern Alternatives to Novocain
At times, dentists may need to perform more extensive procedures that go beyond regular cleanings and exams. These treatments may require the use of local anesthetic medication to numb your teeth and gums due to their sensitivity. You may have heard of dentists using Novocain in the past to numb patients' mouths, but nowadays, safer and more effective drugs like Lidocaine are used instead. These medications are often combined with other substances, such as vasoconstrictors, to enhance their effectiveness and duration of numbness.
Dentists typically utilize two types of local anesthetics to numb your mouth. The first is a topical anesthetic, which is applied to a small area on the surface of your mouth or gums. This is usually done to numb the specific area where the dentist plans to administer the injectable anesthetic. The injectable anesthetic is what ensures your comfort and a pain-free experience during the procedure.
What does the term "Local Anesthesia" mean?
Local anesthesia is administered to temporarily numb a small, targeted area of your body, preventing you from feeling any sensations, including pain. Common procedures that may require local anesthesia include fillings, crown placement, and root canals.
The way local anesthesia works is by blocking the nerve cells in the specific area, preventing them from transmitting pain signals to your brain. The numbness typically lasts for two to four hours, so it's normal to still feel some residual numbness after your appointment.
Before undergoing a procedure that requires local anesthesia, we will ask you about any allergies you may have and the medications you are currently taking. Depending on your medical conditions, there is a possibility that you may need a different type of anesthesia. If you have any concerns or would like more information about how we use local anesthesia, please don't hesitate to give us a call.
What can you anticipate?
Even though the topical anesthetic numbs the area, some patients may still experience a stinging sensation from the injection, leading them to believe that it is not effective. However, this sensation is actually a sign that the anesthetic drug is entering the body and starting to take effect. Rest assured, the stinging will fade away within a few seconds.
Side Effects
Local anesthesia does have side effects, but they are typically not severe. One common side effect is a temporary increase in heart rate, which can occur if the anesthetic is injected into a blood vessel. This is because one of the chemicals used in the injection, epinephrine (also known as adrenaline), can travel directly to the heart. Although the rapid heartbeat may be concerning, it is not harmful and should normalize within a few seconds.
Numbness
The effects of local anesthesia will last for a few hours, causing potential difficulties in speaking and eating. It is important to be cautious after your appointment to avoid accidentally biting your tongue or cheek without realizing it due to the numbness. Temporary swelling or drooping of certain areas of your mouth or face may also occur. In some cases, patients may experience temporary inability to blink, but there is no need to be concerned. If necessary, the dentist can tape your eye shut to prevent dryness, and your blinking will return to normal once the anesthesia wears off.
