Disk displacement is the most common internal derangement of the temporomandibular joint (TMJ) and a frequent reason for orofacial pain consultations. Magnetic resonance imaging (MRI) is the accepted gold standard for confirming the position of the articular disk because it visualizes soft tissue...

Pulp sensibility testing remains the first diagnostic step before any endodontic intervention. Cold, heat and electric pulp tests (EPT) probe the neural response of the pulp through enamel and dentin, and their results decide whether a tooth needs root canal treatment, a direct pulp cap or simple...

Mouthguards protect teeth from sports trauma and night-time grinding, but a dirty guard can become a reservoir for bacteria, fungi and oral disease. Studies show that used mouthguards accumulate plaque, streptococci and Candida within days of normal wear, and poor hygiene has been linked to gingi...

Halitosis, or persistent bad breath, affects a large share of the adult population and carries real social and psychological consequences. In the vast majority of cases the source is the mouth itself, and the most important reservoir is the coating on the dorsal surface of the tongue. Understandi...

Root canal treatment succeeds only when instrumentation stops at the right place. Working length is the distance from a stable coronal reference point to the apical constriction, and every millimeter of error changes the outcome: over-instrumentation pushes debris and irrigant beyond the apex, wh...

Dry mouth is one of the most common complaints in dental practice, yet it is frequently underestimated. Xerostomia is the subjective feeling of oral dryness, while salivary hypofunction is the measurable reduction in saliva output, and the two do not always coincide. Because saliva protects teeth...

Diabetes affects more than blood sugar, and the mouth is often one of the first places where the disease makes itself known. The relationship is genuinely bidirectional: uncontrolled diabetes increases the risk and severity of periodontal disease, while severe gum inflammation makes blood sugar h...

Enamel is the hardest tissue in the human body, but it is not indestructible. Dental erosion is the chemical dissolution of enamel by acids that are not produced by bacteria, and modern diets supply those acids in abundance. Understanding how acidic foods and drinks attack the tooth surface is th...

A good toothbrush should work as well in a hotel bathroom as it does at home, and that is exactly what BrushO Travel Mode is designed to do. By lowering motor speed and trimming acoustic output, Travel Mode keeps the full two-minute cleaning routine in a form that is discreet enough for shared ro...

Coffee and red wine are two of the most common causes of teeth staining, and the stains they leave behind are often considered a cosmetic nuisance rather than a dental health issue. However, these extrinsic stains can make teeth look dull, yellow or brown, and they can affect a person's confidenc...

Mouth sores and ulcers are common oral health issues that can cause significant discomfort and pain. These lesions can affect eating, speaking, and overall quality of life, and understanding their healing times and treatment options can help patients manage them effectively. From common canker so...

X-ray imaging has been the gold standard for detecting cavities for decades, but laser-based technologies now offer a different approach to finding tooth decay. Laser cavity detection uses fluorescence and laser light to identify changes in tooth structure before they appear on an x-ray, and unde...

Facial furrows are not just a cosmetic concern, they are visible markers of the way skin ages and how it responds to dehydration. Dry skin is one of the most common contributors to early and deepening facial lines, and understanding the underlying causes helps explain why certain areas of the fac...

Grinding or clenching the teeth at night, known as bruxism, is more than a dental issue. The muscles that close the jaw are among the strongest in the body, and their chronic overactivation can trigger headaches, ear pain, facial discomfort and disrupted sleep. The connection between bruxism and ...

Decortication, the deliberate removal of a cortical plate to expose or to decompress the tissue beneath it, appears in oral surgery under several names and in several contexts, from transalveolar extraction of a deeply impacted third molar to alveoloplasty of an irregular ridge and to decompressi...

Lichenoid lesions of the oral mucosa present a diagnostic problem before they present a therapeutic one, because the same white reticulated pattern can represent idiopathic oral lichen planus, a contact reaction to a restoration, a drug eruption, or an entirely benign variation such as leukoedema...

Bone in the adult jaw is never quiescent. Roughly 10 percent of the human skeleton is replaced every year, and the alveolar process turns over faster than most skeletal sites because it is loaded intermittently by mastication and by the forces transmitted through the periodontal ligament. The ost...

Root canal treatment succeeds or fails at the interface between the filling material and the dentin wall, and no material has changed that interface more in the past two decades than the calcium silicate bioceramic sealer. These materials descend from Portland cement, set in the presence of moist...

Ameloblastoma is the most common clinically significant odontogenic tumor, and its behaviour is defined less by its ability to spread than by its tendency to return after apparently complete removal. Conservative surgery preserves function and facial contour, and decortication is the procedure mo...

Fluoride in drinking water is the most cost-effective caries preventive measure in public health, and it is also the source of most avoidable fluoride exposure in young children. The balance between benefit and risk depends on concentration, on total intake from all sources and on the age of the ...

A mouthguard is the only piece of protective equipment that a dentist can prescribe, and the difference between the cheapest and the best version is often less than the cost of a single repair. This guide explains what each type of mouthguard actually protects, how to judge fit, and what to check...
