Just for the record. If you do not consume any sugar, carbohydrates, fruits or grains. There is no reason to worry about toothache. By eating carbs you feed the bacteria. If you do not consume any the bacteria only gets as much food they need to barely survive. This is why animals living in nature don't need a dentist. I'm not eating any of these things for more than 2 years and I can attest I would probably not even need to brush my teeth. i did not have any toothache since.
