Red line on bottom on gum where the jawbone sticks out. my dentist said i always had it gave me a special rinse and do the salt water- but its worse?

Ginigivostomatitis: The red line indicates gingivitis.Stomatitis means inflammation of the mouth-especially inside of the mouth. tartar is acalcium salt ,some times getting deposited beneath the gum line which can make this inflammation persisting if unremoved. In addn. to the salt water mouth rinse/ antiseptic rinse, you may need a dental xray to r/o tartar beneath the gum line,a good exam and scaling of teeth.

Red Line: You didnt state how long the red line was. Also if it has always been there it might be an area that has less collagen/keratin in it( whitens the tissue), different parts of mouth have different amounts depending on the type of tissue. By the fact you were given a rinse, your dentist feels that area isnt 100% healthy, maybe an ulcer,( cant tell over the web).

Red line on gum: Can't give an accurate diagnosis without a clinical/visual examination. Check back with your dentist. If you are not satisfied with his/her treatment, see another dentist for a 2nd opinion.

Gingivitis: Red, bleeding and swollen gums can be a sign that you are at risk for, or already have, advanced gum disease. Untreated gingivitis can lead to the tooth loss and other health problems. See your dentist ASAP because the sooner you treat it the better the outcome.

Go Back Again: If your symptoms are not improving, you definitely need to go back to your dentist. If he/she can't figure it out, you might have to see a specialist: oral surgeon, periodontist, endodontist, etc. You absolutely must find out what's going on, as there are some oral conditions which can be quite serious. Might even need a biopsy to be sure. In any case, go back to your dentist right away.
