Lip Trauma From Biting After Local Anesthesia Treatment


Dental procedures that include the use of local anesthetic of the inferior alveolar nerve have the risk of causing lip trauma from biting after local anesthesia treatment. This risk is especially prevalent among youngsters.

Children who come with this ailment that resolves on its own are sometimes mistaken as having a bacterial infection that is confined to a specific area.

In the most severe situations, children have been hospitalized against their parent's wishes and treated with antibiotics given via their systems or surgical procedures. Following a visit to the dentist, the youngster in question bit his lip and was later sent to the hospital for observation.

This case report details this incident. Pediatric nurses are in a unique position to assist both parents and primary care doctors in correctly diagnosing and palliatively managing this benign disease.

Treatment Of Lip Trauma From Biting After Local Anesthesia Treatment

Masticatory lip ulceration caused by anesthesia of the mandibular nerve might be a scary sight for a doctor who has never seen it before. Perhaps this is why some doctors have been reported to treat these non-bacterial ulcers with systemic antibiotics or to order surgical incisions and drainage.

Even though lip biting ulcers often manifest with some regional swelling and edema, they are typically not infections and should be treated as such.

It is difficult for a youngster to know or even feel whether they are biting their upper lip or the inside of their cheek after their mouth has been numbed for dental surgery since this makes it impossible for them to tell the difference between the two.

It should not come as a surprise that this complication has become more prevalent during the COVID-19 pandemic because children are wearing face masks coming and going from the dental office. It is significantly more difficult for a parent to discern whether or not their child has bitten their lip through a face mask.

After undergoing a dental procedure that required the administration of anesthesia, it is vitally important for both children and the adults who care for them to be aware of the fact that they must exercise extreme caution in order to avoid biting their lips or cheeks by accident for the next two to three hours, or until the numbness subsides.

During this period, no food nor drink should be offered to the patient. It is recommended to stay in a setting where the wearing of masks is not necessary so that parents may have a better opportunity to examine their child's mouth. This will help to guarantee that this does not occur.

If your kid bites or chews on their lip or cheek, a traumatic ulcer with a yellowish appearance may occur when the area heals. It might take up to two weeks for this to go gone completely.

During this period, it is essential to keep the affected region clean, to continue with regular dental hygiene practices such as brushing and flossing and to avoid anything that can irritate the wound, such as citrus juices or dishes based on tomatoes. Ibuprofen or acetaminophen may be given to your child as required if they are experiencing any kind of discomfort.
