Allergic reactions to foods, medications, or certain materials, such as latex, can cause the lip to swell. Allergic reactions to food usually develop within minutes of contact with food. However, some reactions can take hours to develop. Allergic reactions to medications can take hours or weeks to develop. This means that a person may wake up with swollen lips if they have eaten a particular type of food or taken a drug that they are allergic to several days before.

Oral allergy syndrome

Oral allergy syndrome, also called pollen-food syndrome, is a type of reaction to raw fruits and vegetables and certain nuts and seeds that can develop in adulthood. Symptoms of oral allergy syndrome are an itchy mouth or tongue and swollen lips or tongue. Symptoms only affect the mouth and do not last long. Consumption of uncooked food is the main culprit. If a person wakes up with swollen lips, they may have eaten foods that triggered a reaction during the night or developed sensitivity to medications over time.

dental appliances

The most common reason a brace can cause lip swelling is that it can rub against the soft tissues inside the lips and cheek, causing swelling and irritation.

Braces are sometimes made of nickel, so anyone with a nickel allergy can have a reaction. However, there are options other than metal braces if a person is allergic.

If a person is punched in the mouth while wearing braces, tissue from their lips or cheeks can get caught in the wire. Separating the lip tissue from the braces can cause additional trauma to the lips, causing swelling as they heal.
