I think it would be fair to say that tongue can only produce light force. Even pushing with all your might, the resulting pressure would not be that intense. Try resisting the upward push of the tongue with a couple of fingers. You will likely find out that the fingers can easily overpower an even seemingly strong push. There should be no harm in mewing really hard as long as you are doing it in proper posture. It worked out for jamo/neveragain. It worked out for others on this forum before him too.

He emphasizes how bones are very susceptible to constant light forces, such as forces from oral posture, as he explains it. However, what about constant mid or high forces? Maybe that works as well, or even better?

Strengthening the tongue is very important for the process regardless of the mewing approach, so for that reason alone I agree that a certain amount of hard mewing always is good.

The AGGA creates forwards expansion/remodeling like nothing ever seen before (even though it of course makes for a different type of change than the change mewing results in, an inferior type of change since it changes the dental arches more than it changes the maxilla itself, even though it seemingly can affect other areas of the face as well), even in adults (see Ronald Ead). To my knowledge it relies on a constant light force, lighter than forces from other devices such as from braces or other palatal expanders (except for maybe the ALF, which might work with a similar force). Whether this is key for its efficiency or not I do not know, but it is worth thinking about.

As for my self, I am pretty much mixing all types, pushing real hard for long sessions mixed with longer sessions of a more gentle push, or with something in between. However, as Progress wrote, perhaps even when one tries to go real hard the force might not be that high..

Hard mewing is a flawed concept because it contradicts two principles set by Dr. Mew, namely bones respond to light and constant pressure and the posterior tongue should rest against the hard and soft palate subconsciously. Forcing the posterior tongue up there over long periods will not achieve that.

It’s common knowledge in physiotherapy that isometric exercises should not last more than 1-2 minutes. The tongue is no different than any other muscle. Hold it for too long and it will strain. People instead should be looking into ways to have it reach that level subconsciously.

A good way to achieve that is to perform tongue chewing and correct swallowing. Such exercises strengthen the tongue and train it to assume the correct position. And speaking of position if the tongue is sitting too low it’s not going to be able to function well.  

That’s why you need to correct your forward head posture. When the neck assumes correct position, the hyoid bone, which the tongue attaches to, goes up giving extra momentum to the tongue.

And none of those exercises can be performed with force. If you watch any video from any expert about forward head posture correction you will find a general note of performing exercises gently. Going hard strains the muscles and causes overcorrection. Other muscles pick up the slack and mess up the function.

It’s like performing a deadlift you have to focus on form before force. I always notice this while performing tongue chewing. If I press too hard I start feeling my teeth clinching. That is a good sign that my mastication muscles are over engaging. Hence that is why you need to chew as well. Everything has to be in balance.  

If you watch dr. mew’s videos in chronological order you will see how this view starts developing over time until he reaches the current understanding presented in his latest video “doing Mewing”.

There is no information available on the full physical effects of FAGGA. The changes you see in Ronald's pictures are not final. FAGGA practitioners contend that further remodling will take place over time. We can't make a final judgement until he presents his pictures after completing the second phase.

As for pressure, FAGGA relies on the patient stimulating the pad with his tongue. It applies a very light force, just to keep the pad in contact with the "spot". If the patient fails to stimulate the spot with his tongue very little expansion will take place.

I would say it contradicts neither principle, because 1) hard mewing is not an actual hard force 2) hard mewing can be done just as constantly and subconsciously as light mewing. It's the same exact action and mechanism. Only the intensity varies.  Of course though, when you push hard with the tongue, the surrounding musculature has to step up its game too. You can only be as strong as your weakest muscle. So in this way I agree with your concerns. 

Thanks for replying guys and @abdulraan good comment I think that might help me out a bit. The reason I posted this wasn’t for hard mewing but it was to point out that everyone’s loght forces differ because some people have stronger tongues than other and I think that hard mewing or tongue chewing( high intensity) short period of time is really beneficial in gainging that strength

A while back you were saying you weren't sure if mewing was actually making you look better.  Then I remember you said that things were starting to look up.  Any updates since then?
