I have a question or in other words a problem
I'm 19 years old
I have a medium thick white line in the upper part of the canine .... went to a dentist and he applied fluoride varnish and it got worse ..... is there any solution to that ? is it a lack of a certain vitamin or mineral ? and ways of how to try to remove that white part of the canine ? does pharmacies released a toothpaste for that issue ?
Thank you for your effort and time
