Can Oral Vacuuming Cause Salivary Cysts? Dental Issues - Dentistry

The concern regarding whether oral vacuuming can cause salivary cysts is quite valid, especially in the context of recent dental work such as the extraction of a tooth and the placement of a dental bridge. Salivary cysts, also known as mucocele, can occur when there is a blockage or damage to the salivary glands, leading to the accumulation of saliva in the surrounding tissues.
In your case, the act of "sucking" or creating a vacuum in the oral cavity, particularly around the areas where dental work has been done, may indeed contribute to the formation of a mucocele. This is especially true if the suction disrupts the normal flow of saliva or causes trauma to the minor salivary glands located in the mucosa of the lips and cheeks. When these glands are damaged or blocked, saliva can accumulate, leading to the formation of a cyst.

The fact that you noticed the cyst appearing after you began to frequently suck on your lower lip and that it reduced in size after you started using a mouthguard suggests a potential link between the two. The mouthguard likely prevented you from engaging in the sucking behavior, allowing the area to heal and the cyst to diminish.

It is also important to consider that after dental procedures, the oral environment can change significantly. The placement of a dental bridge can alter the way your teeth come together, potentially leading to new habits such as sucking or licking the area, which may not have been present before. This change in behavior can inadvertently lead to trauma or irritation of the surrounding tissues, contributing to the development of a mucocele.

In terms of treatment and management, it seems that the use of the mouthguard has been beneficial in preventing further irritation and allowing the cyst to heal. While it may be inconvenient or aesthetically unpleasing, wearing the mouthguard during activities that might provoke the sucking behavior could be a practical solution.
If the mucocele persists or if you experience any additional symptoms such as pain, swelling, or changes in the texture of the cyst, it would be prudent to consult with your dentist or an oral surgeon. They can provide a thorough examination and determine if any further intervention is necessary. In some cases, if a mucocele does not resolve on its own, surgical removal may be recommended.

In summary, while oral vacuuming or sucking can potentially lead to the formation of salivary cysts, it is often a result of the interplay between oral habits and the anatomical changes following dental procedures. Monitoring the situation and maintaining good oral hygiene, along with the use of a mouthguard, should help in managing the condition effectively. If you have ongoing concerns, do not hesitate to seek professional advice to ensure your oral health is maintained.
