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...

Distinguishing reversible from irreversible pulpitis is the single most consequential decision in endodontic diagnosis, because one leads to a restoration and the other to root canal treatment or extraction. The distinction rests on symptoms and pulp testing rather than on radiographs alone, and ...

A pregnancy epulis is a benign overgrowth of gum tissue that appears during pregnancy, most often in the second or third trimester. It can alarm patients because it grows quickly and bleeds easily, yet in most cases it needs no surgery and settles after delivery. Understanding what drives the gro...

When several teeth are missing, the choice usually narrows to a removable partial denture or a fixed implant-supported restoration, and cost is the factor patients raise first. Upfront price is only part of the comparison, because the two options differ in maintenance, comfort, effects on neighbo...

Most root canal failures are not caused by inadequate cleaning of canals that were found, but by canals that were never located. Molar anatomy varies widely, and the variation is not random: specific teeth in specific populations have predictable additional canals. Knowing where they hide is the ...

Gum massage is one of the oldest recommendations in oral care and one of the least understood. It has been described as a treatment for bleeding gums, a route to firmer tissue and, more recently, a way to reduce brushing force. This article separates the mechanisms that are supported by physiolog...

Interdental cleaning is the part of oral hygiene most people abandon first, and the choice between a floss pick and a length of string floss is often made on convenience. Convenience matters, because a tool that is used daily outperforms a superior tool that stays in the drawer, but the two devic...

Dementia changes the way a denture is worn, cleaned and tolerated, and the people who notice the change first are usually family carers rather than clinicians. Poor denture hygiene in this group is associated with mucosal infection, reduced food intake and, in frail patients, respiratory complica...

Chewing tobacco keeps nicotine and plant irritants in prolonged contact with a small area of mucosa, and the damage that results is concentrated exactly where the quid is held. The lesions that develop are often painless, which is why they are discovered during routine examination rather than bec...

Vitamin D is best known for its role in calcium homeostasis and bone mineralisation, yet it also modulates innate immunity and inflammation, both of which are central to periodontal disease. For that reason it has become one of the most discussed nutrients in periodontology, and the question is w...
