I have been taking the exact same brand and within a couple days of taking one tab a day my teeth started to feel very sensitive. I too stopped taking them and my teeth returned to normal. I'm keen to take CoQ10 so took one tab again yesterday and today my teeth are very sensitive!
Any others had a similar experience?
