Maybe some of us wanna try things and see if there is any truth in it or if it works for us. For me oil pulling has worked in that it makes the environment in the mouth cleaner. It feels like after a visit to the dentist every day after they have removed plaque. I haven't done it long enough to see if it whitens the teeth but I am not that interested in having whiter teeth as that can be fixed in other ways and many do these days.
I read about the importance of using the muscles in the face more and you certainly get a workout with oil pulling which is also good for you. I think what this method does is provide oil and moisture to the gums. We are often told to provide moisture to our skin so why would the gums be any different. This way is better than using those coloured mouthwashes as dental experts have now condemned those as they simply do not work and may even give you darker teeth and that happened to my girlfriend when using mouthwash.
People have reported better eyesight and without saying too much I have experienced that in the last couple of days. But the best part is that I can now use the toilet every day and feel much better for it as a regular visit is a sign that you are ok. I believe in the proven science but I also believe in simple methods that fall out of that category. If you wanna improve something then try and see if it works for you or not. I did in the case of oil pulling and it helps me to keep my teeth and gums feeling much better than they did before.
When my girlfriend have visited her dentist in the near future I will come back and report if her dentist found anything or made any comment before we tell her what method we have been using.
