I have noticed 3 cuts/chips on my teeth at the lower front near the gum (no other damage). This is the first time in my life I have damage to my teeth (I am 40 years old).
The cuts are sensitive to brushing and touch (for example a touch with a fingernail).
I went to a dentist and I asked if that was caused by hygienist cleaning (I complained about the hygienist few times and I think she got upset and did this damage to me last time I have seen her; she quit the job shortly after my last visit).
The doctor mentioned that the teeth damage was probably caused by using a hard toothbrush or grinding teeth. It is hard to believe that I got damage on the 3 teeth at once due to the toothbrush. He offered me to buy an electric toothbrush from him. He also filled those 3 chipped teeth.
Can you please advise what is your opinion.
