ok.  I am 68.  dont look my age.  pretty healthy.  have had cancer sores in my mouth since I was a teenager, nothing much...maybe 3 per year.  I bit the very tip of my tongue about 3 days ago and my tongue has hurt in this area, and to my thinking, for good reason, I bit it pretty badly.  Today, at work, I looked in a mirror at the tip of my tongue and there is a white spot right where I bit it, that is perfectly round, slightly raised, and pretty white.  I dont know if I should give this a week to see if it goes away or if it develops into a cancer sore, or if this is by happenstance, an indication of something more serious.  Do you think I should watch it for a handful of days before seeing my doc?
Hi. Thanks for the query. As you have bitten your tongue therefore, there is formation of a traumatic ulcer over the tongue due to mucosal injury. The round white lesion on the tongue tip is due to ulcer formation only. Pain is due to inflammation and tear of mucosa caused due to tongue bite. So my suggestion is to apply Lidocaine gel over the tongue tip and do cool compresses. You should also do warm saline gargles. Avoid hot and spicy foods. If there is continuous pain you can take Ibuprofen. Take vitamin B complex for a week. Hope this helps. Regards.
