Understanding Wisdom Teeth and Excess Saliva
Wisdom teeth, also known as third molars, are the last set of adult teeth to emerge in the mouth. They typically appear during the late teens or early twenties. While many people experience no issues with their wisdom teeth, some individuals may encounter various problems as these molars develop. A common question arises regarding whether these developing teeth can lead to an increase in saliva production.
How Wisdom Teeth Can Cause Excess Saliva
The emergence or impaction of wisdom teeth can contribute to increased saliva production, a condition sometimes called sialorrhea or ptyalism. This response is often linked to irritation and inflammation. As a wisdom tooth attempts to erupt, it can cause friction or pressure on surrounding gum tissues and the inner lining of the cheek.
This irritation can lead to inflammation, especially if the tooth is only partially erupted. A flap of gum tissue, known as an operculum, might cover part of the tooth, creating a space where food particles and bacteria can become trapped. The presence of bacteria and subsequent infection, termed pericoronitis, further exacerbates the inflammatory response. The body reacts to this discomfort by increasing saliva flow, which helps cleanse the area and flush away irritants and bacteria.
Additionally, discomfort and pressure from an erupting or impacted wisdom tooth can stimulate nerves in the jaw and surrounding oral tissues, triggering the salivary glands to produce more saliva. Saliva also acts as a natural lubricant, soothing irritated tissues and aiding healing.
Accompanying Symptoms of Wisdom Teeth Issues
Problematic wisdom teeth often present with other noticeable symptoms, which may occur with or without excess saliva. One common indicator is pain or tenderness in the back of the mouth, such as a dull ache or throbbing sensation. This discomfort can sometimes radiate to the jaw, ear, or even the side of the head.
The gums around the emerging or impacted wisdom tooth may appear red and swollen, feeling tender to the touch or even bleeding. Swelling can extend to the jaw area, making it difficult to fully open the mouth or chew. An unpleasant taste or persistent bad breath can also occur, often due to trapped food particles and bacterial buildup around the partially erupted tooth.
When to Seek Dental Care
If you experience excess saliva or other symptoms of problematic wisdom teeth, consult a dentist. A diagnosis is important to determine the cause of your discomfort. During an examination, a dentist will ask about your symptoms and medical history.
They will also inspect your teeth and gums, focusing on the wisdom tooth area. X-rays provide a detailed view of the wisdom teeth’s position, their relationship to other teeth and nerves, and any signs of impaction or damage. Based on this assessment, the dentist can recommend action, such as monitoring or extraction, if the teeth are causing current problems or are likely to lead to future complications. Dentists often recommend removal in the late teens or early twenties, even without symptoms, as the procedure is simpler and recovery faster at a younger age.
