Hey Docs! My 13 years old son got his bottom of his teeth transparent, it doesn't seem so pleasant, is there anyway to treat it?

Do not worry! This is called incisal translucence. It is normal and cannot be changed or prevented. The condition is not indicative of any pathology or deficiency and no treatment is needed. Just relax, it is a completely normal, especially among younger people who do not have much wear on the biting edges of their front teeth. Take care.
