Experiencing facial numbness after a dental appointment is a common and often disorienting sensation. This article explains why it occurs and offers practical advice to manage this temporary feeling until full sensation returns.
Understanding Dental Numbness
Dental numbness arises from local anesthetics, which block nerve signals in a specific mouth area. This ensures a pain-free experience during dental procedures. The numbing effect’s duration varies based on factors like anesthetic type and concentration. For example, lidocaine typically provides numbness for one to three hours, while bupivacaine might last up to eight hours.
The extent of the procedure and the injection site also influence how long the numbness persists. Procedures requiring more extensive work or injections near larger nerves, such as those in the lower jaw, can result in a longer numbing period. An individual’s metabolism, age, weight, and overall health influence how quickly the body processes and eliminates the anesthetic.
Strategies to Encourage Numbness Dissipation
While patience is often the primary approach as numbness naturally subsides, certain strategies can help sensation return by stimulating blood flow. Gently massaging the lips, cheeks, and jaw can increase circulation to the affected areas. Use light, circular motions with clean hands, avoiding the direct injection site if tender.
Engaging in light physical activity, such as a short walk or mild household chores, can boost blood circulation. Increased blood flow aids the body in metabolizing and clearing the anesthetic more efficiently. Applying a warm compress to the outside of the face, if no swelling is present, can further encourage blood flow and dissipate numbness.
Gentle jaw movements, like slow wiggling, and moving the tongue from side to side can re-stimulate nerves and improve local circulation. Staying well-hydrated by drinking water supports the body in flushing out the anesthetic. Some dental practices offer reversal injections that can significantly shorten numbness duration, though these may not be covered by insurance.
Navigating Activities While Numb
While your face is numb, take precautions to avoid injury. Refrain from eating or drinking hot liquids, as lack of sensation can prevent you from recognizing extreme temperatures, potentially leading to burns. Avoid chewing until full sensation returns, as you could inadvertently bite your cheek, tongue, or lip. If you must eat, choose soft foods requiring minimal chewing, such as yogurt, mashed potatoes, or smoothies, and chew carefully on the non-numb side of your mouth.
Avoid consuming alcohol or smoking immediately after your appointment, as these can interfere with the anesthetic’s effects and delay healing. Defer activities requiring precise facial movements or speech until sensation fully returns. Patience during this period helps prevent complications and ensures a safer recovery.
When to Contact Your Dentist
While temporary numbness is normal after dental procedures, certain signs indicate you should contact your dentist. If numbness persists significantly longer than expected, typically beyond four to six hours, or more than 12 to 24 hours, it warrants a call. Prolonged numbness could, in rare instances, suggest nerve irritation or damage.
Contact your dental professional if numbness is accompanied by new or worsening pain, swelling, or unusual symptoms. This includes sharp pain, persistent tingling, or difficulty moving facial muscles. Early communication allows your dentist to assess the situation and provide appropriate guidance or intervention.
