Does beer mess with your teeth?

You might be experiencing the pain because you brush your teeth too hard. It's best to use a soft toothbrush and make sure not to press down too hard when brushing. You may also want to try some toothpaste for sensitive teeth (like Sensodyne).

I've been told by a Dentist friend of mine that this is a very common issue.

no no, its nothing like that.

I have never ever had sensitive teeth in my life. But just today, all my teeth feel wobbly & sore, sensitive at the roots (pressure) and tips (temperature) really extreme.

But I guess it shall pass.
