It depends on which parts of the the tooth are considered, but pH 6.7 and below is an accurate answer in a general sense. In a living organism, a tooth is constantly being demineralised and remineralised and at pH 5.5 the rates of demineralisation and remineralisation are roughly equal. Below pH 5.5 the rate of demineralisation is the greater and the tooth is effectively being corroded away.
Lemons can corrode your tooth enamel due to the Citric Acid contained within. Lemons can also cause an upset stomach due to an imbalance in the pH levels.
Al is resistant to water-corrosion and will only corrode in acid-based conditions (pH<7).
The pH range for carbonate-bicarbonate buffer is 9,2.
PH levels indicate how acidic or basic a substance is. A pH lower than 7 is acidic and higher than 7 is basic. Since acids dissolve tooth enamel, I would say that substance with lower pHs are more likely to lead to tooth decay.
the pH range is around 10

cavity formation is the word.The tooth tissue starts to decay and corrode .
Al is resistant to water-corrosion and will only corrode in acid-based conditions (pH<7).
10
The range of pH values is 0 - 14.
Nonreactive. They don't rust/corrode
It neutralises any excess acid left in the mouth which might corrode your teeth.
7-14 is the range of base in a pH scale
No.
The toothpaste is slightly basic.
The pH range for carbonate-bicarbonate buffer is 9,2.
no tooth paste is a weak alkali and it's pH nuber is 8
