Q: What is the black line at my gum line under my crown?
A: This is one of two things. If the crown is not all porcelain, then it is porcelain fused to metal, meaning there is a metal substructure with the tooth colored porcelain on top. Many times the metal band will show through along the gum line because the porcelain is thinner there. Another cause could be that the tooth under the crown is darkening and you are seeing the natural tooth just below the crown margin. It is normal for this to occur. However, if it is causing you pain or discomfort please contact Dr. Perry and let her evaluate the area.
Q: I just had my braces removed and there are white spots on my teeth?
A: White spots on the tooth are caused by a demineralization. Basically that portion of the tooth has less minerals and calcium. In this particular case, it was caused from poor oral hygiene while the brackets were bonded to your teeth. If you have found yourself in this situation, ask Dr. Perry about treating it with MI paste. For more information about MI paste see our blog.
Q: Why are my teeth sensitive?
A: Sensitive teeth are most commonly caused by exposure of your root structure. The roots of our teeth are more porous than the crown of the tooth (the portion of the tooth that is visible) and are therefore significantly more sensitive. Why would your roots be exposed? Gums recede from age or trauma and expose the roots, which can cause sensitivity. Toothpaste for sensitive teeth is beneficial in these scenarios.
Q: I just had a filling and now my tooth is sensitive. Is that normal?
A: Sometimes, yes. It can be normal to have sensitivity to hot and cold after a filling is completed. The sensitivity should be mild and it will resolve on its own, usually within a few weeks, sometimes taking a few months. The sensitivity will continue to diminish and become less frequent every day until it goes away completely. If your tooth is sensitive or painful when biting then the filling may be “too high” or “too tall”. If this is the case, call the office and come back in for an adjustment to your filling.
