Dental fillings are one of the most common dental treatments, especially considering how almost everyone gets a cavity once in their life. But whether you are about to get a filling to seal a cavity-infected tooth or simply want to replace an old one, the last thing you want to get stuck with is a numb mouth.

Dentists usually administer anesthetic to their patients before the surgery since it helps numb the mouth, allowing them to work faster. However, sometimes, the effects of the anesthetic can last longer than expected. So then, how long does it take for the numbness to go away after a filling, and can you eat with a numb mouth? If you have the same questions, don’t worry. In this blog, we’re going to break down everything related to the dental fillings procedure.

How Long Does It Take For The Numbness To Go Away After A Filling?

It typically takes around 1 to 2 hours for the numbness to go away after a dental filling, although it mainly depends on the type of anesthetic that the dentist used. Not to mention, the entire reason why dentists numb your mouth before a filling procedure is to prevent any pain or discomfort. While fillings aren’t painful in any way, the procedure can feel a little uncomfortable since the cavity has to be removed and cleaned out of the affected tooth.

It is also important to keep in mind that the patient’s metabolism, blood circulation levels, and overall health play a massive role in deciding when the numbness will fade. While some people recover in one hour, for others, it can take slightly longer. Nevertheless, as long as you follow your dentist’s instructions and take basic preventative measures, you won’t have to worry about anything. However, if the numbness persists for more than 6 hours, contact your dentist and let them know.

Can You Eat While Your Mouth is Still Numb?

No matter how tempted you might be, it is crucial to avoid eating anything until the numbness in your mouth has faded away. This is because numbness can impair your ability to chew properly. If you’re not careful, you might accidentally bite your tongue, lips, or the inside of the cheeks, causing more pain.

Additionally, when your mouth is numb, you cannot tell the difference between hot and cold temperatures, which can lead to burns and other oral injuries. It’s best to wait until the numbness completely subsides, typically within 1 to 2 hours, before eating something. Even then, make sure to stick to soft and lukewarm foods to avoid accidentally setting off the filling.

What’s The Takeaway?

All in all, it takes an hour or two for the numbness to go away after a dental filling. The best thing you can do is to wait patiently for the anesthesia to naturally wear off or try performing gentle jaw exercises to improve blood flow in your mouth. Also, make sure to keep yourself hydrated, as water helps to flush the anesthetic out of your system. However, if the numbness refuses to go away, do not wait around.
