Numbness is a common and anticipated experience following a deep teeth cleaning, a procedure also known as scaling and root planing. This sensation is a direct result of local anesthetics administered to ensure comfort during the cleaning process.
Why Numbness Occurs
Deep teeth cleaning involves working below the gumline, which can be sensitive, so dentists use local anesthetics to numb the area. These medications temporarily block nerve signals in the treated region, preventing pain from reaching the brain.
Common local anesthetics used in dentistry include lidocaine and articaine. These substances are typically injected into the gums or near the affected nerves. The anesthetic molecules interfere with nerve signals, temporarily numbing the area.
Expected Numbness Duration
The numbness experienced after a deep teeth cleaning typically lasts for a few hours. Most patients can expect the sensation to diminish within 1 to 4 hours, though this can vary. For instance, lidocaine commonly provides numbness for about 1 to 3 hours, while articaine may last slightly longer, usually 2 to 4 hours.
Several factors influence how long the numbness persists. The specific type and amount of anesthetic administered play a significant role. The injection site also matters; areas with higher blood flow, such as the upper jaw, may experience a quicker return of sensation compared to the denser bone structure of the lower jaw, where numbness can linger longer. Individual patient factors, including metabolism, age, weight, and overall health, also affect how quickly the body processes and eliminates the anesthetic. More extensive cleaning procedures requiring higher doses of anesthetic may also lead to a longer duration of numbness.
Managing Numbness and Post-Procedure Care
While the mouth is numb, it is important to take precautions to prevent accidental injury. Patients should avoid chewing on the numb side of their mouth to prevent inadvertently biting their cheek, tongue, or lips. It is also advisable to avoid hot beverages and foods until the numbness has completely worn off, as the lack of sensation can lead to burns.
General post-procedure care for deep cleaning involves maintaining good oral hygiene and being mindful of dietary choices. Patients should avoid hard, sticky, or sharp foods that could irritate the healing gums. Mild discomfort can be managed with over-the-counter pain relievers as needed. Gentle brushing with a soft toothbrush and rinsing with warm salt water can help alleviate discomfort and promote healing.
When to Contact Your Dentist
While temporary numbness is a normal part of recovery from deep teeth cleaning, certain signs indicate that professional advice should be sought. If numbness persists significantly longer than expected, for example, beyond 8 to 12 hours or into the next day, it is important to contact your dentist. Prolonged numbness could, in rare cases, indicate nerve irritation or damage, which requires evaluation.
Other symptoms that warrant contacting your dentist include severe or worsening pain, swelling that increases instead of improving, or any signs of infection such as fever or pus. If you experience any unexpected side effects or concerning symptoms, reaching out to your dental office for guidance is always recommended.
