Dental professionals, "transparent teeth"?

Enamel: If you are referring to the edges of the front teeth being transparent, this is usually due to the natural transparency of enamel. Also, severely worn teeth can look transparent.

Depends: You might mean the natural look some front teeth have by their edges, where it looks like very clear, or also can be if teeth are worn out and the edges of the teeth can be very thin.

H2O2 Use?: If you are asking about how to get, or what causes 'Transparent Teeth' then my initial answer would be prolonged use of Hydrogen Peroxide. Many studies have shown, as well as my own clinical experience, that prolonged use of H2O2 can result in extreme translucence of the incisal edges of anterior teeth, and posterior cusp tips. This is not usually a problem, unless sensitivity results.

Clearer teeth: The enamel that covers teeth can be more translucent or opaque in different patients and may give the appearance of transparent teeth at the edges where the re is no dentin under the enamel

Thin teeth?: Do you drink a lot of soda and/or citrus? Must remove the cause before trying to protect ; preserve what you have left of your enamel. Acids from soda and lemons, etc, as well as over-whitening them wear away the teeth enamel, making them look too thin. Solution: proenamel toothpaste, act Fluoride mouthwash, ; seeing a dentist to make sure they do not need some kind of protective restorations.
