Mouth Breathing in Children and Adults: Why It Is Harmful and How to Manage It

Mouth breathing is a chronic dysfunctional breathing pattern linked to anatomical obstruction, habits, and sleep-related disorders.

📌 Recommended Article :

Dental Article 🔽 Oral breathing: new early treatment protocol ... Mouth breathing is multifactorial, and its consequences are short and long term, and it is evident in the oral cavity and in general health. Early evaluation and treatment by the pediatric dentistry and pediatrician is necessary.

Its long-term consequences affect craniofacial development, oral health, systemic physiology, and quality of life. Early diagnosis and intervention are essential to prevent irreversible changes, particularly in children.

✅ Introduction
Mouth breathing refers to the predominant use of the oral cavity instead of the nose for airflow at rest. While occasional mouth breathing during a cold or intense exercise is normal, persistent oral respiration is clinically significant. Research shows that chronic mouth breathing disrupts nasal filtration, alters muscle activity, modifies dental arch development, and contributes to both malocclusions and sleep-disordered breathing (Zaghi et al., 2022). Early identification is crucial because craniofacial structures in children are still developing and more susceptible to functional changes.

▪️ Ensuring correct fulcrum position to avoid cortical plate fracture.

📊 Comparative Table: Differences Between Adult and Pediatric Forceps

Aspect	Advantages	Limitations
Size & Dimensions	Pediatric forceps are smaller and designed to fit limited oral openings; reduce soft-tissue interference.	Smaller size provides less mechanical advantage and may limit grip on large or multi-rooted teeth.
Beak Design & Adaptation	Pediatric beaks are shaped to match primary tooth crowns and slender roots, minimizing accidental damage to developing permanent teeth.	Adult beaks offer broader purchase on permanent tooth anatomy; pediatric beaks may not engage adequately on malformed or erupted permanent teeth.
Handle Length & Leverage	Shorter handles improve control in small mouths and reduce operator hand fatigue during pediatric procedures.	Reduced leverage can make difficult extractions more challenging and may necessitate adjunctive techniques (e.g., elevators).
Trauma Risk & Clinical Use	Pediatric forceps tend to be less traumatic to alveolar bone and adjacent tissues when used correctly; suited for atraumatic extractions in children.	Adult forceps provide greater force and may cause collateral damage in small jaws; pediatric instruments may be unavailable in some settings.

💬 Discussion
Current literature emphasizes that extraction success depends not only on clinician skill but also on matching forceps geometry to tooth anatomy. Forceps with anatomical beaks distribute forces more efficiently, reducing risk of alveolar bone damage. However, universal forceps remain valuable in pediatric and general practice settings due to their adaptability.
Newer ergonomic designs and improved steel alloys have increased precision and tactile feedback, but biomechanical principles remain unchanged: controlled force, correct fulcrum, and proper luxation are essential.

📌 Recommended Article :

Dental Article 🔽 Inferior Alveolar Nerve Block: Risks, Complications, and Prevention ...However, due to its proximity to vital neurovascular structures, improper technique or anatomical variations can lead to neurological, vascular, and muscular complications, which may be transient or, in rare cases, permanent.

✍️ Conclusion
Correct forceps selection according to tooth type enhances procedural predictability, minimizes trauma, and improves postoperative healing. Universal forceps are practical, but anatomy-specific instruments provide superior biomechanical efficiency in complex extractions. Mastery of both instrument selection and atraumatic technique remains essential for safe and successful practice.

🔎 Recommendations
▪️ Use universal forceps for routine anterior extractions but switch to anatomy-specific instruments for molars.
▪️ Apply controlled luxation before traction to minimize fractures.
▪️ Incorporate clinical radiographic evaluation to anticipate root divergence, curvature, or anomalies.
▪️ Consider specialized forceps (#23 cowhorn) for mandibular molars with advanced interradicular bone loss.

▪️ Use systemic fluoride only when strictly indicated, following updated FDA criteria.
▪️ Evaluate each child’s total fluoride exposure, including water, toothpaste ingestion, and diet.
▪️ Educate parents on safe brushing practices to minimize swallowing.
▪️ Monitor for early signs of dental fluorosis in high-risk communities.

✍️ Conclusion
Determining how much fluoride is “too much” requires balancing preventive benefits with safety, especially in developing dentition. The 2025 FDA restrictions reinforce a conservative approach to systemic fluoride use and highlight topical fluoride as the mainstay of pediatric caries prevention. Clinicians must remain updated and tailor fluoride exposure to each child’s unique risk factors.
