It does not take a great deal of damage to put your tooth pulp at risk for an infection. A cavity or even a crack that is almost too small to see can allow bacteria to create a problem. In the past, this issue would have required an extraction. But at Lake Highlands Dental, our dentists can use a root canal treatment in Dallas, Texas, to preserve your tooth and your smile. Call 214-613-1279 to schedule an appointment with Dr. Sajjad Ashnagar and Dr. Kyle Young.
