Sometimes i notice some white lines on my front teeth after brushing them.which disappear when i wake up.what are these ?
A doctor has provided 1 answer
Neo-natal line: Top 2 front teeth often have mark about 1/3 of the way from the biting edge to the gum line. The bottom 1/3 is the part of the tooth that developed in utero, the top 2/3 developed after you were born. Depending on dryness, cleanliness, light refraction, etc, it is sometimes easier to see this neo-natal line than other times.
