Foul taste and smell

I am currently 5 months pregnant. I have my teeth cleaned yesterday and for the past week or so I have been experiencing a foul taste coming from between two of my back teeth. The dentist did not say anything about it yesterday. The taste is terrible and when I floss between those two teeth it smells awful. What do I do?

Answer: Foul taste and smell

By Sarah h
Dental Professional

It sounds like you may have an open contact between the two teeth or possibly decay. When the contact point between the two teeth is open, or a larger space than normal, food and plaque can collect. If not removed immediately the food starts to decompose and produces a gas, which could be the odor you are smelling. If there are crowns on one or both of the teeth, there is a possibility of an open margin. In this situation you could be collecting plaque and/or have recurrent decay under the restoration. If the dentist didn't take radiographs, due to you being pregnant, they cannot see what is going on in between your teeth. It doesn't hurt to call the office and explain the circumstances and that you would like the area looked at. In the meantime, keep the area very clean with brushing, flossing, and mouthwash or warm salt water rinses. This will help to eliminate the amount of bacteria in the area until it is healed or restored.
