[|Human|] I have a lump on the side of my tongue with indentation all around it and two sores on the back top part - the dentist shone the light in my mouth that s supposed to detect abnormal cell growth and it didn t sho anything -- are those lights effective or should I be worried?
[|AI|]  Hi Dear, Indentations sometimes occur along the lateral borders (the sides), as the result of compression of the tongue against the adjacent teeth. When tongue becomes larger than normal, it will press onto your teeth. This tends to cause indentations. There can be many reasons for indentations like Swollen tongue, which could be due to allergies, some disease and conditions such as amyloidosis, hypothyroidism, tongue cancer, canker sores, scarlet fever and angioedema. If light test doesn't show anything then there is nothing to panic. The lumps you mention in query are probably due to canker sore due to frictional trauma. These usually go away in few days without any treatment. Do Betadine rinses, speak less so that your tongue doesn't get hurt and do HY Chat Doctor.  If condition persist then consult oral pathologist for proper evaluation. Hope your concern has been resolved.
