It usually starts with a sudden, sharp pain in one of your teeth when you bite down on something extremely hot or cold. After a bit, the pain goes away and you think that it was just an isolated incident. Then, it happens again the next time you indulge in a cup of coffee or a bowl of ice cream. At this point, it does not take you long to realize that there is a serious problem deep within your tooth that is now hurting you much of the day and night. Here is where our Baton Rouge dentistry services can uncover a hidden cavity or hairline fracture in your tooth that can be easily and effectively remedied with root canal therapy.
