Dental injections are a common part of routine dental work, helping to make treatments easier and more comfortable for patients. But how long do they take to heal? The answer depends on the amount of anesthesia used and the individual's metabolism. Generally, the effects of local anesthesia will last between two and five hours, gradually wearing off as sensation returns to the area. In most cases, the anesthesia used by the dentist will numb the tooth for 1 to 2 hours. However, this doesn't mean that numbness subsides immediately after that.
The effects of novocaine can last for 3 to 5 more hours after leaving the dental office. This can be frustrating if you try to return to your normal activities immediately after your appointment. Be patient and let the feeling and sensation in your mouth return. While the numbness will naturally go away over time, there are home remedies that can help speed up the process. Additionally, some people have a fast metabolism and may need several rounds of anesthesia during a dental procedure to maintain dental anesthesia. Surprisingly, it is also possible to quickly resolve the feeling of numbness in the mouth once the dental treatment has been completed by receiving an additional injection after the treatment is over.
