NHS trials new cooling mask to soothe pain and swelling after dental surgery
The NHS is trialling a new cooling mask, which could be used to reduce pain and swelling that occurs following dental surgery.
It is common for patients to suffer from trismus, which causes pain and makes it difficult to open the mouth after surgery, and the new mask could help to make patients feel more comfortable in the days after the procedure. The plastic mask, which is designed to fit closely to the face, contains tubes, through which water is piped. There are holes for the eyes, mouth, and nose, and the aim is to tackle pain and decrease inflammation.
Cooling the skin has been used for decades to treat swelling and alleviate pain, but the new mask uses targeted relief at the optimum temperature for narrowing blood vessels. Research suggests that 15 degrees is the optimum temperature for cooling the skin and constricting blood vessels. This mask is attached to a machine, which is located at the patient’s bedside; it pumps water into the tiny tubes inside the mask at 15 degrees. The mask can be applied during the procedure, which means that the patient can enjoy instant benefits.
Prof Thomas Dietrich is leading the trial at Birmingham Dental Hospital, and he believes that the mask could be beneficial for thousands of patients who experience pain and swelling following procedures like wisdom tooth extraction. Although the mechanics are relatively simple, it is hoped that the feedback will be positive. A group of 60 patients will take part in the trial with half using the mask after treatment.
