recently i noticed the ends (say 1/3) of my teach are looking
translucent instead of an opac off white. i'm a 36 man. i was thinking
about things i have changed in the last few months that might have
caused this.

i have changed my diet. eating more roughage, more fruits and veggies.
eating less refined sugars and carbs.

also, per my dentists instructions, wearing a hard mouth guard he made
for me.

i'm drinking green tea, but i have been drinking that for years now.

very recently, the last month, i have been averaging about one coke a
day (mixed with jack daniels). i am a social drinker but hardly ever
drink sodas.

anyone with knowledge on this topic have an idea?

much thanks.
