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...

The toothbrush aisle offers dozens of options, but the variable that matters most is not the handle colour or the grip. It is the stiffness of the bristles. This article compares soft and medium bristles using the evidence that actually informs clinical advice, from plaque removal to gingival saf...

Few topics generate more parental anxiety than teething, and few are surrounded by more persistent myths. The evidence shows that tooth eruption causes milder and narrower symptoms than most caregivers expect, which means that a distressed infant with a fever usually needs a diagnosis rather than...

What you eat in the week after a tooth extraction shapes how comfortable that week feels and how quickly the socket closes. A soft food diet is not simply an instruction about texture; it protects the blood clot, supplies the nutrients that rebuild tissue and prevents the pressure and suction tha...

A crown that is designed, milled and fitted in a single appointment sounds like a straightforward improvement on the two-visit routine, but the comparison is more nuanced than marketing suggests. Fit, survival and cost all depend on the material and the operator as much as on the technology used ...

Osteoporosis treatment and dental care intersect at a single, serious complication: medication-related osteonecrosis of the jaw. The condition is uncommon but consequential, and the risk is strongly shaped by decisions made long before a tooth becomes a problem, which is why patients and clinicia...

A click in the jaw when opening the mouth is one of the most common findings in dentistry, and one of the least understood by patients. For most people it is a harmless mechanical event, but in a minority it signals a joint problem that benefits from assessment and conservative treatment.

Fluoride is the most effective caries-preventive agent available, and parents encounter it in two very different forms: the toothpaste used at home every day and the varnish applied in the dental chair. The two are complementary rather than competing, and understanding what each contributes preve...

Enamel defects in children range from small white patches that cause no trouble to large areas of missing enamel that expose dentine and break down soon after eruption. Recognising the type of defect and its cause allows clinicians to prevent the breakdown rather than simply repair the damage.

A short sharp sensation on drinking cold water is one of the most common complaints in the days after a restoration, and it is also one of the most misunderstood. Most episodes resolve without intervention, but a minority reflect problems that need attention, so knowing the timeline and the warni...

Hyperdontia is the presence of one or more teeth in excess of the normal dental formula, and the resulting teeth are described as supernumerary. The condition is common enough to appear in routine practice but variable enough in presentation that the decision to intervene is rarely straightforwar...
