Have you noticed a thin white line running along the inside of your cheek?
This condition, called linea alba, is often harmless and linked to pressure or friction in the mouth. However, it’s important to know when it could indicate a more serious issue, such as leukoplakia or other oral health concerns.
In this article, we will explain the causes of linea alba in the mouth, how it differs from other conditions like leukoplakia, and when you should consult a dental expert.

Linea alba is typically a harmless condition caused by friction or irritation, but persistent oral changes should never be ignored. If you have concerns about oral health, AZ Max Oral Surgeons are here to help.
What Is Linea Alba?
Linea alba appears as a thin, white line on the buccal mucosa (the lining inside the cheeks), where your upper and lower teeth meet.
It’s typically benign and results from repeated friction, pressure, or irritation.
Common Causes of Linea Alba:
- Cheek biting: Habits like cheek chewing can irritate the soft tissues, creating a visible white ridge.
- Orthodontic appliances: Braces, aligners, or dentures may apply excessive pressure on the cheeks.
- Uneven teeth: Misaligned teeth can lead to chronic friction against the cheek lining.
- Dry mouth: Reduced saliva increases friction and irritation in the oral tissue.
| 💡Did you know? Linea alba is especially common in Invisalign wearers due to the snug fit of the aligners, which can create friction against the cheeks. Actions like clenching or trying to clear excess saliva by drawing it away with your tongue can increase irritation, leading to the formation of the white line. While usually harmless, persistent irritation should be discussed with your dentist or orthodontist. |
Linea Alba vs. Leukoplakia: Key Differences
While linea alba is harmless, leukoplakia may indicate a more serious issue.
Leukoplakia appears as persistent white patches that cannot be wiped away and sometimes signals precancerous changes.
What About Hairy Leukoplakia?
Hairy leukoplakia, often associated with immunocompromised individuals, typically develops on the sides of the tongue. It may appear corrugated or “hairy” and requires prompt evaluation by a dental professional.
Can Linea Alba Be Linked to Oral Cancer?
Most cases of linea alba are benign. However, chronic irritation or lifestyle factors like tobacco and alcohol use can increase the risk of developing oral cancer. Warning signs include:
- Asymmetrical lesions or patches
- Reddish spots or persistent white lesions
- Pain, swelling, or unusual growths
Regular oral cancer screenings are crucial for identifying and addressing these conditions early.
Tips to Maintain a Healthy Mouth
Practicing good oral hygiene and addressing potential irritants can minimize the risk of linea alba and other oral health issues.
- Brush and floss daily to keep your teeth and gums healthy.
- Stay hydrated to prevent dry mouth.
- Limit tobacco and alcohol, which are common risk factors for oral cancer.
- Correct dental misalignments to reduce friction and irritation.
- Schedule regular dental exams to catch any concerning changes early.
- Perform regular oral cancer checks at home.
