Hello Thanks for sharing these details. It sounds like you’re dealing with a persistent lip border issue that started after using Sensodyne toothpaste, with white buildup after getting wet, thinning and flattening of the lip border, and mild burning.

### What This Could Be Your symptoms suggest a form of chronic irritant contact dermatitis or possibly cheilitis (inflammation of the lips), likely triggered by an ingredient in the toothpaste. Over time, repeated irritation and cleaning can thin and flatten the delicate skin at the lip border, and cause mild burning.

### What You Can Do 1. Stop Using the Trigger: If you haven’t already, switch to a very mild, non-fluoridated, non-foaming toothpaste for a few weeks. 2. Gentle Lip Care: Avoid scrubbing or cleaning the area aggressively. Pat dry after washing your face. 3. Moisturize: Use a bland, fragrance-free lip balm (like plain petroleum jelly/Vaseline) several times a day, especially after eating or washing. 4. Avoid Irritants: Don’t use flavored, colored, or medicated lip balms, and avoid spicy or acidic foods that can worsen burning. 5. Sun Protection: Use a lip balm with SPF if you’re outdoors, as sun can worsen lip inflammation.

### When to See a Doctor - If the burning, thinning, or white patches worsen or don’t improve in 2–3 weeks with gentle care. - If you notice cracks, bleeding, persistent pain, or any new lumps/ulcers. - A dermatologist can examine your lips, rule out other causes (like lichen planus, fungal infection, or vitamin deficiencies), and may prescribe a mild topical ointment if needed.

### Will It Get Better? Most cases like yours do improve with gentle care and avoiding triggers, but it can take a few weeks for the lip border to heal and regain its normal texture. Try not to worry—this is not usually a serious condition, but it does need patience and gentle handling.

Thank you

But my lip border is moved down and backwards due to dryness of a year and white color appears after bath when I clean it now this area looks like flat and part of lips line.how will be normal and heal

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. Use zytec gel Tab folvite 5 1 tab daily for 10-14 days.

Hello dear See sensodyne has been successfully tested in human trial and no side-effects have been reported Probably it is an allergic reaction to one of the components probably desensitised agent. I suggest you to please stop and replace sensodyne with Colagate or pepsodent Do regular mouthrinsing with water Take zincovit multivitamin therapy for b2 deficiency and lip irritation Please follow fir atleast a week In case of no improvement consult nearby dentist for better clarity Regards

Hello

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.

Take care

It seems you’re experiencing a dermatological reaction related to the use of Sensodyne toothpaste, possibly an allergic reaction or irritation triggered by specific ingredients. Some toothpaste formulations contain SLS (Sodium Lauryl Sulfate) or certain flavorings that can irritate sensitive skin, especially around the lips. The symptoms you’re describing — thinning skin, burning sensation, and the appearance of a white color after exposure to water — may indicate that there’s some ongoing inflammation or irritation. Initially, it would be advisable to stop using the toothpaste immediately, and switch to a hypoallergenic or SLS-free alternative. Make sure to choose a toothpaste that’s free of strong flavorings or other potential irritants. Next, apply a gentle, fragrance-free moisturizer or a medical-grade lip balm to the affected area to help repair the skin barrier. Look for products containing ceramides, as they can aid in skin restoration. Additionaly, avoid licking your lips or touching the area frequently, as this can exacerbate the irritation. If your symptoms persist despite these changes, or if the condition worsens, it’s important to consult a healthcare professional or dermatologist. They can assess whether there’s an underlying dermatological condition that needs addressing. Sometimes, topical treatments with corticosteroids or other medications might be needed to reduce inflammation and promote healing. Remember, if you experience any severe reactions like swelling, difficulty breathing, or intense pain, seek immediate medical attention. A professional evaluation is crucial for persistent or worsening symptoms, so you can get an accurate diagnosis and appropriate treatment plan.
