"IF" you were eating foods which were supplying your body with enough Alkaline Minerals and in particular, enough Calcium so that the roots of your teeth were able to supply the rest of your tooth with what it needs to build a strong and healthy tooth, then your teeth would be healthy enough that the lemon juice or the ACV would not cause any problems!
But, since you have not yet figured out, that "IF" the root cause of your overall problems is from a Lack of enough Alkaline Minerals to be able to neutralize the Acid Thoughts and the Acid environment and the Acid foods which you may be consuming, then until you figure this out and take some planned action to correct these problems, then your body is not going to be able to heal it's self from your over-acidic problems!!!!!!!!!!!
You have continually complained about how Calcium Hydroxide just can not work and how most of these ideas can not work and have tried one or the other and then did not get the results you wanted and so would continued to Complain, yet have been unwilling to utilize them together as has been suggested!!!!!!!!!
So, because of your Acidic attitude you may "NEVER" get healthy , until you correct the way you think and are willing to consider it all together and to start thinking Positive!
You are as bad as the person who gets a car and the car needs oil in the engine to lubricate the bearings and water to cool the engine and gasoline to burn to power the engine, yet you have decided that you do not need to add water to the radiator or oil to the crank case, and you are "ONLY" willing to add gasoline to the gas tank, and you start the car up and do not make it out of the drive way, because the engine Locks up from lack of oil and water!!!!!!!!!!
Do "NOT" come on this forum any more and say these ideas do not work, when you are not willing to do the needed planned action to obtain positive results which these other people who are making the Positive efforts and taking planned action and are getting Positive results!!!!!!!!!!!!
When you are able to Grow up and take responsibility for your own actions,and stop complaining, then, maybe you will get some Positive results??????
And when you are willing to grow up and take responsibility for your own actions without complaining , then you may be welcome again on this forum??
