How Long Does Dental Anesthesia Last?

Anesthesia is very helpful in many medical situations that need the patient not to feel the pain during the treatment or operation. Difficult medical procedures have become easier with the help of anesthesia. Without it, many people cannot endure the pain which can lead to more serious problems. 

In a dental clinic, a local anesthesia is being used to numb the muscles or teeth in an area where the dentist needs to work. Sometimes, that anesthesia comes with epinephrine to increase the numbing effect. 

In America, more dentists use anesthetics with articaine component. A report published by the Journal of American Dental Association in 2011 shows that articaine is more effective than lidocaine in making you numb. If you’re the type of person who has difficulty getting numb, ask your dentist to use articaine as anesthesia.  

If you will go to your dentist Ontario and needs a procedure that will require shot of anesthesia, inform your dentist if you have heart problems. Your dentist needs to use anesthesia without epinephrine. Epinephrine is known to make the heart beat faster, especially if it is injected into a blood vessel. The drawback of an epinephrine is that the numbness does not last long, so you need multiple shots in order for it to be effective. 

The most important question about the use of anesthesia in dentistry is how long the numbness will last. The answer is dependent on the amount of anesthesia injected and its components. Usually, after the injection, local anesthesia will make the tooth and gums numb for up to 2 hours, while your lips and tongue will be numb for 3-5 hours. The pain will be felt once the anesthesia is carried by blood flow away from the area where it was injected, or the anesthesia is broken down or metabolized. 

If you need the numbness to go away quickly, you can talk or do physical activities if your dentist says it’s okay. Or, you can ask your dentist if you can have Oraverse. It helps get rid of numbness twice as fast. Oraverse might cost you $25-75 more, and your dental insurance may not cover it. 

If your child is administered with anesthesia, observe his reactions when it starts to wear off. Because kids don’t know the strange feeling caused by anesthesia, most of them would chew on the inside of their cheeks, tongue, and lips and it might cause serious damage.
