Your symptoms are most likely due to chronic irritation of the lip border (irritant contact dermatitis) that began after using Sensodyne. Some people develop sensitivity to certain toothpaste ingredients, especially foaming agents or flavoring chemicals. Repeatedly cleaning or rubbing the white area when it gets wet can also thin the skin over time and cause the mild burning sensation you described. This condition is usually not dangerous and does not mean permanent damage, but it can persist if the irritation continues.
What you should do now is switch to a very gentle, non-foaming toothpaste and avoid rubbing or scrubbing the lip border frequently. Apply a simple protective layer like petroleum jelly to the area two to three times daily to help the skin heal. Try to gently pat the area dry after bathing or brushing instead of wiping repeatedly. If the burning continues, a doctor may prescribe a short course of a mild antifungal or anti-inflammatory cream to calm the irritation.
If the skin keeps thinning, develops cracks, bleeding, spreading redness, or does not improve after about two to three weeks of gentle care, you should see a doctor or dentist for an in-person examination.
Your symptoms suggest that you may have developed chronic irritation or contact-related inflammation of the lip border (likely a form of irritant contact cheilitis), possibly triggered initially by the Sensodyne toothpaste and worsened over time by repeated moisture exposure and frequent rubbing or cleaning. The white appearance when wet, along with thinning, flattening, and slight recession of the lip border, indicates ongoing skin barrier damage and mild inflammation. The associated burning sensation further supports irritation rather than infection. Overall, this seems to be a chronic but manageable condition caused by long-term irritation and overhandling of the area, and it typically improves with avoidance of triggers, gentle care, and proper skin barrier repair.

Sir I have also have a chronic stress and I have Dryness so this white color appears on lip border maybe due to sensodine toothpaste and dryness so I used to clean it about a year daily basis unknowny . So now lip border moved down and backwards physically can it be heal. Maybe my texture change of skin .
Your symptoms with the lip border, particularly after using Sensodyne toothpaste, suggest you might be experiencing a local allergic or irritant reaction. This isn’t uncommon with certain toothpaste ingredients such as sodium lauryl sulfate (SLS), flavoring, or other excipients which can cause irritation in sensitive individuals. This could explain the burning sensation and changes to the skin texture and appearance. To address these changes effectively, first, consider switching to a toothpaste formulated for sensitive mouths, that doesn’t contain SLS or artificial flavors. Opt for a milder, hypoallergenic option, which is often labeled as ‘natural’ or ‘SLS-free’. Ensure that you rinse your mouth thoroughly with water after brushing and avoid any toothpaste residue on your lips. Since you’ve described ongoing changes in your lip border over a substantial period, it’s prudent to consult with a dermatologist or your primary care physician. They can assess whether further treatment is needed, like topical steroids or barrier creams to reduce inflammation and protect the skin while it heals. Monitoring for any additional symptoms is important. If you notice increased pain, development of blisters, or wider spread of irritation, seek medical attention swiftly, as this may indicate an infection or more significant underlying cause that requires immediate intervention. Meanwhile, applying a bland, unscented lip balm can help to protect the area without further irritation. Maintain hydration by drinking sufficient water daily, as dry lips can exacerbate discomfort. Avoid licking lips, as saliva can irritate and worsen symptoms. With these strategies, hopefully, irritation and healing will improve, but always align home management with professional healthcare advice whenever in doubt.
