Hi,
I have two teeth, the ones two and three teeth to the right of my front most tooth (sorry I don't know how to describe the location better). The past few weeks they have been very sensitive when it comes to rinsing my mouth with cold water after brushing. So much so that I started using warm water to do so. I have discovered that they each have a ridge along the very top on the front side of the tooth. Above the ridge, if touched with a finger, is extremely sensitive. None of my other teeth have this particular ridge or sensitivity issue.
Thank you so much for your help.
