This is a very good and effective toothpaste. I have been purchasing this from a very long time. I’ve had a root canal treatment and so the dentist recommend it to me. The cleansing effect is very good and it also has a nice taste. The power of hydrogen is also basic to normal. The burning sensation is also very less if you accidentally directly apply it on your gums. The effect of the toothpaste last long enough, but don’t expect it last long like 8 to 12 hours. All in all this a great toothpaste and I recommend to anyone who have had some problem I their teeth.
