Fever blisters are caused by a herpesvirus. They do know that sometimes too much sunlight, or illness may result in a break-out of fever blisters, which are very contagious, especially when the fluid filled blisters are present. Siegel says dentists should be observant if they have a patient who's being treated for sun-damaged skin. The most common pre-malignant skin lesions show up on the prominent parts of the face, such as right above the eyebrows or on the lower lip. The sun shines down and so the lower lip is one of the most common sites for skin cancer.
Dentists also look for cancer in the mouth.
Dentists routinely look for oral cancer during regular check-ups. Siegel reminds people with dentures, who may not go to the dentist as often as they should, to visit the dentist at least once a year to make sure the inside of their mouth is healthy.
