<human>: Is it true that if I get a root canal, I will have a bad breath?
<bot>: Yes, it is true that if you have a root canal, you may experience some temporary changes in your sense of taste and smell. This can include an increase in the intensity of your breath for up to several weeks after treatment. However, this should not be a cause for concern, as most people do not notice any significant change in their breath after having a root canal.
