Mewing, as a DIY facial restructuring technique, lacks sufficient scientific evidence to definitively prove its effectiveness, though some underlying principles have research backing.
While anecdotal evidence supports claims that mewing – the practice of keeping your tongue pressed to the roof of your mouth to reshape the jawline – can alter facial structure, the scientific community requires more robust studies to validate these claims.
Here's a breakdown:
-
What is Mewing? Mewing involves consciously positioning the tongue against the palate (roof of the mouth). Proponents suggest this practice can improve jawline definition, correct bite issues, and enhance facial aesthetics.
-
The Lack of Scientific Consensus: The core problem lies in the scarcity of well-controlled, large-scale studies specifically investigating mewing. Much of the support comes from individual testimonials and before-and-after photos, which are subjective and lack scientific rigor.
-
Underlying Principles with Some Backing: The fundamental idea behind mewing – that tongue posture and oral habits can influence facial development – aligns with some established orthodontic principles. For example:
- Myofunctional Therapy: This therapy addresses oral habits like tongue thrusting and mouth breathing, recognizing their impact on facial growth.
- Orthotropics: This branch of orthodontics focuses on guiding facial growth through posture and oral habits. John Mew, whose name is associated with "mewing," is a proponent of orthotropics.
-
The Need for Further Research: While the principles may have some merit, applying them through self-directed "mewing" requires careful consideration. Improper technique could potentially lead to jaw pain or other complications. Well-designed clinical trials are needed to determine if mewing is genuinely effective and safe.
In conclusion, while the concept of mewing has gained popularity, concrete scientific evidence supporting its effectiveness remains limited. The underlying principles align with some established orthodontic concepts, but further rigorous research is necessary to validate its claims and ensure safe practice.
