I used jojoba and it didn't work very well.
I suggest you brush your teeth with toothpaste.
Step 2: Use mouthwash
This is what I am using now, and the effect is very good. My mouthwash and toothpaste are Colgate's, and they are quite easy to use.
Just don't use it often. Colgate 360 toothpaste can clean your teeth.
