I had been using crest 3D white toothpaste last night and it made my gums swell. So I am switching toothpaste. The toothpaste I am going to use is called UltraBrite. So I did not know if it was was safe to use crest 3D white mouthwash after brushing my teeth with UltraBrite toothpaste? Any help would be appreciated. Thank you so much.
