Mouth Feels Numb After Filling? How Long Does This Sensation Last?

We understand your dread when it comes to going to the dentist for a filling, not only because of the work but also because of the numbness that follows. But that does not mean you put off the idea of getting your oral health in check. Moreover, the numbness after getting your cavities filled lasts for just 1 to 2 hours, something that you can manage easily.

Understanding the Numbness

Dentists use local anesthesia to make sure that there is no pain during the treatment. While the effect lasts for about 1 to 2 hours in the tooth, it may leave your lips, face, and tongue numb as well for 3 to 5 additional hours.

Relieving Numbness After Filling

Here’s what you can do:

  1. Massage Your Skin
    In case there is no swelling in the treated area, use a warm compress to wake it up. Apply it to enhance blood flow and reduce numbness. Moreover, a gentle massage of your lips can warm them up and boost blood circulation. Just make sure to wash your hands before and after.
  2. Get Active
    Before you go home, ask your dentist if it is safe to engage in physical activities right away or not. Activities such as brisk walking, a bike ride, or home chores can help reduce numbness in a natural manner. Physical activity stimulates blood flow that helps carry the anesthesia away from your injection site.
  3. Take a Nap
    We recommend you take a rest. Napping can help you take your mind off the numbness. Just relax and let the sensation pass by.
  4. Ask for An Antidote
    Some dental practices also offer an antidote to reverse the effects of local anesthesia. It can make the numbness go away twice as fast as just waiting it out. However, do keep in mind about the additional cost.
  5. Stay Calm
    The standard duration of numbness is 1 to 2 hours; however, the actual number varies from one person to another, depending on the severity of filling and factors like your height, weight, and how fast your body metabolizes the anesthesia.

When To Seek Your Dentist Help?

While it is a given to experience lip and mouth numbness for a few hours following your dental filling, persistent numbness that passes the 5-hour mark is a problem. Lingering numbness might indicate nerve damage during the procedure, so a follow-up visit is crucial.

Closing Note

Dealing with a lack of mouth sensation post dental filling is a bit frustrating, but with the steps mentioned above, you can speed up the recovery process.
