Mouthbreathing is heavily associated with tooth proclination. This means the teeth are tilted more forwards and set less balanced on each other. This obviously causes you to bite your lips easier cause the lips are way more pressed upon the place where your teeth touch
"The upper incisor proclination (P = 0.012) and facial convexity (P = 0.003) were significantly higher in mouthbreathers with adenoid hypertrophy. However, upper incisor proclination (P = 0.009) was statistically signifi cant only in group MB when compared to NB. Conclusion: All subjects with mouth-breathing habit exhibited a significant increase in lower incisor proclination, lip incompetency and convex facial profile."
